ABSTRACT
Scientific Study of fish fauna of River Swat was started by McClelland in 1842. Fish being one
of the most important part of the biodiversity has remained the focus of many researchers in the
area. It is included in most food chains and all food webs of aquatic bodies. Fish is considered as
one of the most important and efficient bioindicator of the water body. Biodiversity studies of
aquatic ecosystems cannot be considered complete unless fish diversity/ ichthyodiversity in the
water body has not been fully explored and identified. Study and identification of fish fauna of a
water body gives us the idea about its health and about its economic value. Main objective of the
study was to idntify the complete fish diversity of the River Swat and make a pictorial
identification key.
In present study fish fauna of River Swat and one of its major tributaries, River Panjkora was
collected and identification of species was done.
The work was started in 2012 and collection was made using cast nets, hand nets and many local
devices with the help of fishermen of the area. The main focus was to collect all species present
in the area. Using standard keys fishes were identified.
An exclusive pictorial dichotomous taxonomic key was constructed for the identification of
fishes of river swat. The most important quality of the key is that it can be used not only by
researchers and students working on the fauna of River Swat, but it can also be used by a lay
man as coloured pictures of all the fishes are given in the key. This key also provides the local
names of the fishes along with scientific names for ready reference. Using the key, the fish fauna
/ ichthyofauna of river Swat was identified to species level.
14
All the 62 species identified from the river belong to Superclass Gnathostomata, class
Actinopterygii, subclass Neopterygii, division Teleostei and superorder Ostaryophysi. These
fishes belong to seven orders namely Cypriniformes, Siluriformes, Salmoniformes,
Mastacembeliformes, Perciformes, Beloniformes and Channiformes. Fishes are included in 11
families; Cyprinidae, Nemacheilidae, Bagridae, Schilbeidae, Sisoridae, Salmonidae,
Mastacembelidae, Ambassidae (Chandidae), Belontiidae, Belonidae and Channidae. These 11
families are further divided into 38 genera. Order Cypriniformes and family Cyprinidae have
been proved as the largest family and order of the fishes in River Swat. The most abundant
species were Barilius pakistanicus and Triplophysa microps and the least abundant were
Schistura macrolepis, Glyptosternon reticulatum. The comparison of the present collection
revealed that some fishes like species of Tor and Schizothorax are under great stress of
extinction from River Swat. Some fishes seem to be missing from this river now as they were
reported previously but not found in present collection example being Chela cachius,
Aspidoparia morar, Amblypharyngodon mola, Devario devario, Naziritor zhobensis, Schistura
naseeri, Glyptothorax naseeri, Colisa faciata and Colisa lalia etc. The reasons for this species
loss may include mighty flood of 2010, illegal fishing, pollution and habitat loss.
It was concluded that although River Swat has favourable environment for fish survival but due
to above mentioned reasons it is not an ideal habitat for fish now. Conclusion was made that
River Swat can help in solving protein deficiency issue and improve socio economic conditions
of the area.
Proper management, implementation of laws and awareness of masses is strongly recommended
to conserve fish and aquatic resources of this area.

Chapter 1
INTRODUCTION
1.1 Aquatic EcosystemWater can be called the most important chemical compound for the survival and
distribution of life on the earth. It can rightly be called as womb of life as life appeared, sustained
and flourished in the water and it seems to be the driving force in creating biodiversity on this
planet. Allah (SWT) emphasized its importance in the holy book, Al Quran by saying
“And We have created everything from water, will they not then believe”? (Al-Quran,
21:30).
Despite being the most abundant compound on earth, its availability for the earth’s
terrestrial life processes has remained limited in many parts of the world and with heavy human
demand this essential commodity is becoming increasingly scarce.
1.1.1 Aquatic ecosystem and its RoleWater creates a very vast, unique and diverse ecosystem. Aquatic ecosystem is unique
because of its dynamic physical and chemical implications on life. It is more viscous than air and
has more effects on biogeochemical cycles as well as activities and behavior of organisms
(Alexander and Fairbridge, 1999). It provides reduction in weight due to an upward thrust that
reduces the effects of gravitational chains which always bind/tie up the life of organisms on land
and needs a large amount of energy to overcome hence causes great ease in
movement/locomotion of organisms present in it.
1
Aquatic ecosystem carries out different significant conservation utilities, e.g. recycling of
nutrients, refreshing Earth’s water and deliver habitations for biota.
Aquatic ecosystem is comprised of two major types; marine and freshwater whereas
brackish water is a transition between them. About 71% Earth’s surface is covered by marine
ecosystem and comprise almost 97% of the world’s water (Alexander and Fairbridge, 1999).
These are differing from freshwater ecosystems by the existence of high water dissolved salts. Of
the dissolved compounds in sea water about 85% are chlorine and sodium. Marine water has
mean salinity value of 35 ppt (3.5%). Marine ecosystems account for about 32% of the planet’s
net primary productivity (Pfafflin and Zeigler, 2006)
Approximately 0.8% surface of earth is enclosed by freshwater ecosystems and consists
of 0.009% of the Earth’s total water (Alexander and Fairbridge, 1999). Freshwater ecosystems
have three main types i.e. lentic (standing or slow water flow), containing ponds, lakes, and
pools, lotic (running or fast water flow), like rivers and streams and wetlands; water saturated
places (Kalff, 2002). They produce approximately 3% of the Earth’s net primary productivity.
According to Gleick (1996) total water present on earth is about 1.386 billion Km3, whereas only
178,520 Km3 is available as freshwater (176,400 Km3 in lakes + 2,120 Km3 in rivers); This tiny
fraction of global freshwater is the home of thousands of species of insects, nematodes, worms,
plants and is very important for human consumption. Approximately 41% fish species of the
world inhabit freshwater ecosystems which is only 0.1% of the total earth water resources
(Nelson, 1994). In addition, the available freshwater is utilized by human beings for their
domestic, household purposes as well as in agriculture and industries.
2
Importance of water is not limited to freshwater only, rather its role in both freshwater
and marine ecosystems are paramount for life diversity. Both these basic forms of aquatic
ecosystems harbour the great diversity of life, generally termed as biodiversity.
1.2 Study of BiodiversityBiodiversity is knowing all about, everything, finding, collecting, and naming or
identification of all the species present in the research site. Natural diversity means different for
different scientists (Pearce and Warford, 1992).
1) It may be native species number or their number of individuals in any habitat or area.
2) Diversity of habitats within some area.
3) Different types of interactions occurring among species in some habitat.
4) Genetic variation present amongst same species, different genes present, and their
relative abundance.
As biodiversity is very complex and we know little about it much therefore it is required
to know and quantify it by knowing the most basic “genetic variation” also known as “genetic
diversity”. This could be described as genetic variation which affect the productivity,
characteristics, survival, resistance to stress and alter the performance of ecosystem (Naeem et
al., 1994).
Species diversity is another recognizable part of biodiversity. It is the most common type
which is generally studied extensively (laymen consider and recognize only this type of diversity
as biodiversity). Generally, all the species or all the species of some specific group of an area are
studied in biodiversity (Maes et al., 2014). Some species e.g. talking in terms of fish diversity,
Schizothorax plagiostomus and Gara gotyla are abundant, other such as Xenentodon cancila,
Tor putitora, Labeo dero etc. are declining and may become extinct in our waters.
3
Associations among different species is 3rd aspect of biological diversity. This type of
association makes biological communities which may include areas like forests or wetlands (Das
and Pande, 1978). Communities form the biotic parts of ecosystems i.e. anthropogenic activities
influence the biodiversity (Beyer et al. 2010). Diversity of ecological processes and set of
environmental factors confirms the diversity in an ecosystem and thus enhance the reliability of
the ecosystem (Naeem and Li, 1997).
In general, biological diversity may include all kinds of ecosystems, patterns present in
them. Therefore, it could be said that "totality of genes and species and totality of all the
ecosystems in a region is called biodiversity.
1.3 Importance of Aquatic BiodiversityMarine and freshwater ecosystems especially supply a large variety of food resources,
services and other goods for the human population. For aquatic ecosystems, biodiversity is very
important feature for the protection and stabilization of an ecosystem as mentioned by Ehrlich
and Wilson (1991), is also necessary for the commercial fisheries and maintenance of aquatic
natural resources for the future. Obviously aquatic biodiversity is vital to the sustainable
productivity of fisheries. Therefore, fisheries, with developing more species or populations have
balanced clasps than fisheries developing with the presence of one species (Hilborn et al., 2003;
Dulvy et al., 2000). Conserving such diversity or biological density of population, provides
flexibility and protects against the changes in habitat (Yachi and Loreau, 1999). Biodiversity
gives help to save ecosystems services which are essentially important for the people of poor
countries.
Environment of river can be assessed by studying fish biodiversity; therefore, it is
important to study it (Shinde et al., 2009). Generally, not only fishing but other geological and
4
physical changes cause major changes in fish diversity. In the last few decades, a steady increase
in the habitat loss in aquatic environments, especially of rivers has been observed which suffer
the fish fauna with high mortality due to change in river bed as well as habitat (Pearsons et al.,
1992). In 2010 massive flooding caused serious damage to the fish resources of northern parts of
Pakistan. This loss is directly affecting the fisheries resources which need to be conserved for
future generation by passing conservation laws and making masses aware (Welcomme, 1985).
1.4 Factors affecting Aquatic diversity and their resultsRecently aquatic diversity has gained more attention of natural and social scientists due
to its economic importance (Clausen and York, 2008). In Millennium Environmental Assessment
(MEA) conference, 1400 scientists assembled from 95 countries, stated, that the changes
occurred in biodiversity in last 50 years as the result of human activities were the fastest if
compared with the past changes in human history (MEA, 2005). As for as the loss of aquatic
fauna is concerned, its distribution and arrangement is more, rather absolutely, dependent on
biotic (e.g. Human activities, competition, predation, recruitment) and abiotic (Hydrodynamics
Salinity, temperature of water, habitat differences, variation in seasons, etc.) factors (Whitfield,
1980, 1999; Blaber and Blaber, 1980; Day et al., 1989).
Aquatic diversity is threatened worldwide by a number of human based issues like habitat
loss, changes in climate, eutrophication, pollution and invasive species (Solbrig, 1996). The most
extreme and most recent threats are introduction of invasive species into culture systems and
lakes etc. which later make their way to running water habitat as well. One of the biggest
examples in our country is the introduction of Cyprinus carpio and Oreochromis spp. which
being very hardy are giving a very tough time to our native fish. Although there is no study
available, but these fishes have almost become invasive. An extra threat in this regard has begun
5
currently, is the escape, and in many cases, introduction of genetically modified fish (Dale et al.,
2002) whose effects on diversity would be far more severe. Changes in use of land is also
disturbing biodiversity. Construction of dams is one of the most serious threats to aquatic and
especially fish diversity. In Pakistan, energy crisis has forced the governments to make number
of large and dozens of small dams which are posing serious threats to fish fauna. Change in
climate is previously disturbing the distribution of species and its upcoming effects are expected
to be more widespread (Sala et al., 2000).
In Pakistan a huge flood in 2010 whose severity was the most prominent in Khyber
Pakhtunkhwa (KP) was a clear evidence of climate change which had destroyed and depleted our
aquatic diversity to a great extant.
Fishing rather overfishing is another core issue that threatens the ichthyodiversity
globally. Due to overexploitation worldwide over forty different marine fish populations became
extinct (Dulvy et al., 2003). These damages show global biodiversity destrucion.
This issue of overfishing is not confined to oceans only, rather freshwater habitats are
more affected by overfishing. Even in our province our important food fishes like Tor and
Clupisoma are seriously threatened and their catch is becoming meager every year. Tor putitora
has been in the assessed as endangered in IUCN Red list of threatened species of 2018
(www.iucnredlist.org).
There are many common challenges to the aquatic diversity of the world which are also
destroying the fish and other species of aquatic environments in Pakistan, in Khyber
Pakhtunkhwa and in River Swat as well. Among these the most common and most important are
deforestation, aquatic pollution due to dumping of domestic wastes, industrial wastes and
agricultural runoff etc. (Dudgeon et al., 2006; Moyle and Cech, 2011).
6
1.5 Role and importance of fish in Aquatic ecosystem Freshwater fish fauna constitutes an important part of the aquatic ecosystem and are very
important for their economic, aesthetic and social importance. The freshwater fish fauna is not
only the most diverse assemblage among vertebrates, but also the most endangered one (Duncan
and Lockwood, 2001). Relatively freshwater fishes have inhabited in a limited space (i.e. Lake or
river etc.) having very low capability of inter-basin movement (Unmack, 2001); in comparison,
marine fishes have comparatively free-movement, so freshwater fishes are facing more severe
conservation problems.
Fishes are the keystone species of aquatic ecosystem which confirm the existence and
richness of other organism representing the health and indicate the quality of water in an
ecosystem (Kumar, 2000). Fishes are concerned with the indication of ecological and
biodiversity quality and have been used successfully in the study of biogeography, conservation
evaluation, delineations of the ecoregion and assessment of water quality management
(Economoua et al., 2007).
In modern world fish is the most important component of the aquatic ecosystems because
of its economic value. According to FAO (2018), about 3.2 billion people, mainly in
unindustrialized countries, depend on fish as their main (20%) animal protein source. According
to Kura et al. (2004), small island countries and sub-Saharan African countries, mostly rely on
fish as a food, numerous of which depend on fish for over 50% of their animal protein sources.
In Pakistan, dependence on fish is still lesser as compared to other sources of animal protein like
poultry, mutton and beef.
Fishing is a vital source of employment in numerous developing countries, mainly for
little-income families in rural regions. It is estimated by the FAO that some thirty five million
7
men are directly involved whichever full or part-time, in practices of fishing. More than 95% of
them belong to developing countries, and majority of them is limited fishers (FAO, 2002). In
Pakistan, fish and fish associated industries make about 1% of our GDP.
1.6 Need of studying Fish diversityAs a stable item of diet of the most people, fishes are the essential element in the
economy of countries. Measuring the abundance of species ((which means to study total species
present in a habitat at some location) is basic step for not only field studies but also for studying
community ecology proper management and conservation of biodiversity (Colwell and
Codington, 1994; May, 1988). Count data is a term used for total number of species counted at
some place at given time is used to measure the richness of species as studies carried out by
(Karr et al., 1990; Dawson et al., 1995; Knick and Rotenberry, 1995; Enoksson et al., 1995;
Schiek et al., 1995; Thiollay, 1995; McIntyre, 1995; Riffell et al., 1996). Such works examine
temporal trends which means the space and position to find the richness of species or sometimes
natural conditions on species present locally.
Pakistan has a good diversity of freshwater fishes. The total number of fish species are
182 whereas KP has a diversity of about 78 fishes (Mirza, 2016).
1.7 Special Status of Ichthyodiversity of Khyber PakhtunkhwaOur province has generously been gifted large natural water resources by Allah
Almighty. Fish and fishing have remained one of the most important part of the economy of the
people of the province. A sizeable majority of the people, especially living near freshwater
bodies like rivers, streams, lakes, dams etc. earn their livelihood from fishing. Therefore, it is
very important to find out about the actual ichthyodiversity which will be helpful in conservation
management and further enhancing this precious resource. Identification of fish diversity will
8
help to understand the quality (species number) and quantity (relative richness of species) of the
fish resources.
Study of ichthyodiversity also helps to identify the potential candidates for fish culture as
our culture system is running on only 5 species (rohu, mori, grass, silver and china carp) from
last 5 decades.
Our province has vast natural water resources. We have many big rivers like River Kabul
and River Swat which join to form River Indus. Many other small rivers like Panjkora, Tochi,
Kurram, Kalpani, Jindi etc. also flow across the length of the province and mainly fall into two
major rivers i.e. Swat and Kabul.
For the present study, River Swat, one of the largest rivers of the province was selected.
Importance of this river is that it flows through a course of 150 Km from Kalam to Charsaddah.
Another reason for selecting this river for Ichthyodiversity studies is its unique feature of having
three distinct temperature zones;
1- Cold water zone
2- Semi cold-water zone
3- Warm water zone
1.8 Fish Identification and its importance
The key developed for the fish fauna of this river will help a lot for identifying common
species of fishes of this province as this river contains majority of the fish species found in this
province.
Fish can be identified by following three methods
9
1- Inspection method
2- Taxonomic Key method
3- DNA barcoding/fingerprinting
In first method a fish is identified only by its very prominent physical features. Some
fishes are recognized by their shape e.g. eel can easily be identified by its long snake like
body. Some fish have special marks on the body like those of genus Puntius and Barallius
which have specific black spots (Puntius) and black bands (Barilius) on their body. some
has specific type of fins like curved dorsal fin of Cyprinus carpio and others have some
specific colouration like goldfish etc. These permanent features make them easily
identifiable. However, confirmation of identification still requires other methods to be
followed.
The second method of fish identification which is the most prevalent and the most
commonly used method, is the identification through taxonomic keys. These keys are
basically dichotomous keys as they are developed on the basis of pair of contrasting
characters. Mostly these characters are external, but some internal characters are also
included for the identification of certain fishes. These characters in case of fish are of two
types
a. Morphometric measurements
b. Meristic count
Morphometric measurements are lengths taken from different parts of the fish body. Following
are some important morphometric lengths
i. Total length
10
ii. Forked length
iii. Standard length
iv. Head length
v. Eye diameter
vi. Snout length
vii. Pre orbital length
viii. Post orbital length
ix. Pre dorsal length
x. Post dorsal length
xi. Body height/depth
xii. Body thickness
xiii. Length of CP (caudal peduncle)
xiv. Height of CP
Practically these lengths are not used in fish identification. Actually, the ratios between
different lengths are used for identification and confirmation of species. Similarly, all these
lengths are not required for identification of every fish.
Meristic count is the counting of the fin rays and lateral line scales of a fish. This count is a
tool for species confirmation.
An old method of fish identification is by using its otolith which could also be used to
assess the age of the fish as well.
11
Third method of fish identification is a modern method evolved after the recent
development in biotechnology. This method is based on DNA analysis and is considered very
perfect although selection of DNA source and target DNA segments are objected by some
researchers. Another limitation of this method is its high cost due to the the requirement of high
quality lab equipment and computer analysis softwares which are scarcely available in
underdeveloped countries like Pakistan. Hence this method of fish identification is rather not
used for identification rather confirmation of the species identified by taxonomic key method.
1.9 Introduction to Study areaRiver Swat is part of Malakand Division along with many other rivers of the area. Before
describing the River Swat a view of the whole riverine network will enhance the understanding
of the true picture of the area and that of river swat. Malakand Division is characterized by
green forest, glaciers, high mountains and abundance of water resources. Its Riverine Network
consists of five rivers namely River Swat (district Swat), River Barandu (district Buner), River
Shangla (district Shangla), River Chitral (district Chitral) and River Panjkora (District Dir) along
with their tributaries. Being rich in fauna and especially cold waters, MRN freshwater ecosystem
and especially River Swat has tremendous biological importance.

Fig. 1.1 Main water resources of Pakistan (source: https://en.wikipedia.org/wiki/List_of_rivers_of_Pakistan)
This network of rivers is considered as the main pillar of the economy of this region. Its
water is utilized for household, for irrigation, for industries and above all the water creates a
unique ecosystem in which large number of aquatic animals and plant species are present.
1.9.1 Swat Valley and River Swat:River Swat (34.1166662 - 71.7166638) (http://latitude.to/articles-by-country/pk/
pakistan /39059/swat-river ) originates in the form of rapid stream arising from glacial lakes and
snow covered high mountains of Swat Kohistan. These streams get united and form Ushu and
Gabral Rivers which both unite to form River Swat at Kalam. River Gabral originates from the
mountains around Chitral, whereas river Ushu arises from the hills present in Badagai area of
northern Swat Kohistan. River Swat enters Malakand Agency at Landaki and then flowing across
the agency, as a natural boundary between Malakand and Dir, it receives water from its major
tributary, River Panjkora, near the village Totakan. Dozens of streams fall in River Swat during
this run from Kalam to village Totakan.
13
The lush green and historic Swat valley lies between 34.30`- 35.55`N latitudes and
71.45`-72.45`E longitudes. Swat is the masterpiece of natural beauty and is full of a variety of
plant and animal resources. Swat has an area about 5337 sq. km.
The old name of Swat in Buddhist era was “Udyana” means garden. Historians from
Alexander time has mentioned the name of “Swastu” for River Swat which is derived from the
word Sweta means “white” which seems true for its clear water. In Tuzak-e-Baburi, Babar, the
great Mughal king has mentioned the name “Swad” for this area (D.C. R, 1999).
Melting of snow is the main cause of water flow in spring (March) to summer (June) but
after this the flow of river is due to rain fall especially, in monsoon (July, August). The elevation
of the mountains in Swat varies 600 to 6000 feet and this fluctuation has a great effect on the fish
diversity. The only drainage basin of this area is River Swat and its canal network. Therefore, it
has a main role in socio- economic strength of the Swat valley. Its water is important from
drinking to power generation and from protein source to ecotourism.
As mentioned above, River Swat starts at Kalam after the confluence of River Ushu and
Utror/ Gabral. Up to Chakdara it flows for 160 km in the valley, and then flows some 90 km
more (total 250 Km) up to Naguman, Charsadda where it joins River Kabul. Large number of
tributaries join the main river along its course.
River Swat flows at higher speed in mountainous areas, from Kalam to Madyan, where
its average width is between 35-40m and this narrow course continuous up to Thalapand
(Baghderai). From here downstream the River Swat may spreads up to 400m. it again becomes
narrow in the extreme south of the valley and receives water from River Panjkora at village
Qalangi. Two big canals; Lower Swat canal and Upper Swat canal have been made for electricity
generation at Jaban and Dargai and irrigation of plains of Peshawar valley.
14
Swat is situated in upper part of Khyber Pakhtunkhwa and River Swat is running in the
middle of the district between the hard rocks while somewhere in the plane areas. it start from
Fig. 1.2 Rivers of Khyber Pakhtunkhwa
15
The snow filled peaks of Hindukush feed small streams which join to make the river Swat. The
river has its value in the agriculture of the area. Its irrigation system gives a lot of benefit to the
province. From the river swat two large canals namely, Upper Swat Canal and Lower Swat canal
or the Abbazai canal have been constructed and now a new canal is also under construction these
canals irrigate large parts of the province like the Malakand agency areas some parts of the
Mardan district and Nowshehra and some area of Swabi district on the river hydro power
projects also runs which gives a high voltage electricity.
But above all these, it has a lot of fish species which are famous for their delicious taste
and have a high value in the markets and gives a lot of job opportunities to the peoples of the
area.
River Swat from Kalam to Talapanr flows in a narrow course ranging 15-30 m and then
spread up to 400 m in the width. Water flow increases down the stream due to the tributaries
which join it. These tributaries are mostly rainwater fed. These tributaries join and the flow of
water as well as water quality of the river is affected. Some tributaries are seasonal while others
are perennial. Water volume in these tributaries fluctuates a lot due to seasonal variation. Details
of these tributaries are as follows.
Some of the tributaries of river Swat are listed as follow,
i. Gahil stream
It is the 1st stream which joins river after Kalam. It is a big water body. It starts from the
lofty glacier of Gahil catchments.
ii. Mankial stream
16
Mankial stream joins main river at an area called Mankial. Water of this tributary is very
cold and ideal for trout growth and culture.
iii. Darral khwar
This stream originates from lake of Darral and enters Swat river at a town Bahrain. This
water is suitable for trout culture.
iv. Chail Khwar
This khwar starts in Chail area of village Beshigram (danda) and falls in River Swat at
Madyan. Government of KP has established a Trout hatchery on this khwar in Madyan.
v. Bawari khwar
This originates from Sakhra Lalku catchments andenters River Swat at Kalakot. Its water
is comparatively warm and Schizothorax species are present in it.
vi. Haronai River
Spinsar area is the origin, water comes from alpine catchments. It enters main river swat
at Bamakhela. Schizothorax spawns in this water.
vii. Minglawar khwar
This stream originates from Malam Jaba and enters river swat near Sangota.
We use the term upper Swat for the area above Mingora and lower Swat for the area
below Mingora to Dargai. Rather more correct is that lower parts of River Swat include areas up
17
to Charsadda where it joins River Kabul. Thus, the above-mentioned tributaries lie in the range
of upper Swat. Major tributaries of lower Swat region of River Swat are given below.
i. Hazara khwar
It originates from the mountains of Nekpekhail, Shah Dherai and join River Swat near
Hazara.
ii. Jambil khwar
It originates from the mountains of Jambil and another of its tributary, (Marghazar
Khwar) comes from Elum Mountain both join at Mingora. It is highly contaminated with various
pollutants from Mingora city and its water enters the Swat River as dead water body (E.P.S
Swat, 2003).
iii. Ghalagay khwar
It originates from the mountains of Ghalagay and join river Swat at village Ghalagay. It is
a seasonal tributary that flows in monsoon season.
iv. Amluk darra khwar
It originates from Elum and joins river Swat at Barikot. It is a perennial tributary of river
Swat, having warm water (Temperature 25° to 30°c). Mostly having species of Schizothorax,
Barilius, Carassius, etc. (Findings of the present study).
v. Mulk e adam khwar
It originates from the junction of Swat and Buner Mountains and Join River Swat near
Barikot. The Amlukdara Khwar and Mulk-e-Adam Khwar both join at Barikot before falling into
18
river Swat. It has species of Garra, Crossocheilus, Schizothorax, Mastacembelus, etc. (Findings
of the present study).
vi. Kota khwar
It starts from mountains of Chowa and Sandoka and meet with river Swat near Landakay.
It is perennial tributary and having species of Barilius, Channa, Mastacembelus, Carassius,
Schistura, Puntius, etc. (Findings of the present study).
vii. Parrai khwar
Its start from mountains of Parrai and meet the River Swat near Barikot. It is also a
seasonal tributary that flows in monsoon season.
viii. Thana khwar
Its start from the mountains of Nalloo (Malakand Agency) and enter river Swat near
Thana Bypass. It mostly depends on rain water (DCR, 1999).
ix. Amandara head works
Amandara Head Works is the point from where upper Swat canal arises and irrigates
299979 Acres agricultural area of Peshawar & Mardan. It was completed in 1918. River Swat
has an annual flow volume of 5440 M illion Cubic Meter here with a winter minimum discharge
of 36.5 Cusecs and a maximum summer flow up to 443 Cusecs (www.malakand.com).
Many other streams like swat Ranizai and Adenzai also joins the river swat but the
catchments of these streams have lost its vegetation covers and hence lost its production.
19
1.9.2 River Swat’s Division: River Swat can be differentiated in two major zones on the bases of trout. Trout zone and the
other non-trout one (Fisheries dept. KP)
a. Trout Zone:
This zone starts from initiation of River Swat up to the Bridge at Madyan. This zone
cannot be considered a border for the presence of trout as people catch trout near Talapanr bridge
Baghderai and sometimes in Fiza Gut park. This zone is an arbitrary division and may be
extended upto Baghderai Bridge as trout is generally caught upto here.
Trout area has its unique water characteristic. The average aquatic temperature remains
up to 15o Ċ and average air temperature up to25o Ċ. Generally, temperature is highest during
July- August. Speed of water in this zone is fast due to presence of rocks. Minimum water depth
in summer is 10 m and in winter about 5 m whereas its average width remains between 15-30
meters. Oncorhynchus mykiss (Rainbow trout) and Salmo trutta fario (Brown trout) are two main
species found here.
b. Non Trout Zone:
This zone comprises the part of river below Madyan up to its confluence with River
Naguman near Charsadda; including its tributaries. A great variation of temperature is found in
this zone which has its effects on fish diversity.
In this part water temperature fluctuates from 15o Ċ-18o Ċ whereas in its tributaries from
Mingora downstream it fluctuates between 20o Ċ-25o Ċ. The ariel temperature during summer
fluctuates a lot and at Madyan it is 25oĊ and at Chakdara 37o Ċ. The ecological zone supports
many fish species e.g. Schizothorax esocinus, S. plagiostomus, R. labiata, G. gotyla, C. carpio,
20
C. auratus, C. gachua, M. armatus, T. macrolepis, T. naziri, T. choprai, S. alipodotus, B.
pakistanicus, P. sophore etc. Lebeo dero, Glyptothorax cavia, Xenontodon cancila,
Crossocheilus latius diplocheilus, Glyptosternon reticulatum etc. are also found in it.
1.9.3 River Panjkora; the major tributary of River SwatPanjkora is the biggest tributary of the river. The term Panjkora is derived from Persian
“Panj” means “Five” and “Kora” means “River”) distributing the upper and lower District Dir
into 2 equivalent parts flows southwards and is initiated from Kohistan, District upper Dir. River
Panjkora then joins River Swat at Bosaq bridge in Village Sharbatti. The name Panjkora as
described above, is because of five streams that fall in it at four different locations. River
Panjkora flows in north–south direction. Many streams join it on both sides during course of
flow in district. The river falls, near village Kolangi, into river Swat in the extreme south of
district Dir.

2) Barawal falls in River Panjkora at Chukiatan, Dir Upper.
3) Ushera Dara stream falls in River Panjkora at Darora, Dir Upper.
4) Nurhund stream falls in River Panjkora at Darora, Dir Upper.
5) Karoodara stream falls in River Panjkora at Akhagram, Dir Upper.
1.10 Aims and Objectives To identify the complete icthyodiversity of river Swat
To develop a most recent, pictorial key for the identification of the fishes (as the keys
available are obsolete and cause lots of problems in identification. Available keys are
either written by Indian authors or by researchers from the Punjab which donot fulfil our
needs. Some species of KP are even missing from these keys).
To compare the diversity with other rivers of KP and search for the unique features of
this river.
To analyze the specific changes in the fish diversity of River Swat by comparing it with
the fishes reported by previous workers.
To compare the pre flood and post flood situation of faunistic diversity of river swat.
To strengthen Natural History Museum, Department of Zoology, University of Peshawar.

LITERATURE REVIEW
River Swat is an important water body of Khyber Pakhtunkhwa. Fishery biologists have
started showing their interest towards it two centuries ago. The very first work on the
identification of fishes from River Swat was published by McClelland in 1842. He worked on the
collection of freshwater fishes made by William Griffth during his travel to Swat from 1835 to
1842.
After the creation of Pakistan many researchers worked on this river but most of the work
was focused either on certain important species or confined to certain easily accessible areas of
the valley. A preliminary survey of ichthyofauna of Swat was conducted by Hussain and Shah
(1960) who identified only six fish species from the river viz. Schizothorax curvifrons,
Schizothorax longipinnus, Schizothorax esocinus, Schizothorax plantifrons, Schizothorax nasus,
Schizothorax progastus. Surprisingly they did not mention any other group of fish from the river
except Schizothorax. None of these fish have been reported by any other worker till now. One of
the reasons seems misidentification as these fishes have neither been reported earlier nor after
them.
Ahmad and Mirza (1963a) worked on the loachs of Genus Nemacheilus and published
two papers. This study includes only one family of the fishes found in River Swat. In the same
year, Ahmed and Mirza (1963b) published another work on “Hill Streams Fishes of Kaghan and
Swat” and described only 9 species from the area.
25
Ahmad (1969) reported only 8 species including Salmo trutta fario, Schizothorax
labiatus, Schizothorax plagiostomus, Nemacheilus choprai, Nemacheilus rupicola alipidotus,
Nemacheilus naziri, Nemacheilus punjabensis naseeri, Glyptosternon reticulatum.
Mirza (1973) conducted fish fauna survey of Swat and adjoining areas; Mingora,
Madyan, Bahrain and Kalam. He reported 27 species; Salmo trutta fario, Salmostoma
punjabensis, Barilius vagra, Danio devario, Aspidoparta morar, Labeo dero, Crossocheilus
latius diplocheilus, Tor putitora, Puntius ticto, Schizothoraichthys labiatus, Schizothoraicthys

four new records namely Barilius vagra, Puntius ticto, Crossocheilus latius diplocheilus and
Channa gachua.
Mirza and Hameed (1975) worked on the fishes of sub family Schizothoracinae in which
they referred to three species found in River Swat.
Butt (1986) made an extensive work on ichthyofauna of N.W.F.P. in which he described
15 fish species from different parts of River.
Latif (1999) worked on the fauna of lower part of River Swat at Malkand Agency and
described 15 species; Puntius ticto, Garra gotyla, Mastacembelus armatus, Channa puctata,
Barilius vagra, Triplophysa naziri, Schistora alepidota, Schizothorax plagiostomus,
Schizothorax labiatus, Schizothorax esocinus, Tor macrolepis, Crossocheilus latius,
Glyptothorax reticulatum, Glyptothorax stocki and Eutropiichthys vacha.
26
Rafique and Javed (2002) also worked on fish fauna of River Swat and Bunair and
reported 24 species from both areas.
Yousuf (2004) studied the fish diversity of lower part of River Swat and reported 20 fish
species including Barilius pakistanicus, Crossocheilus diplocheilus, Carassius auratus,

Xenentodon cancila, Oncorhynchus mykiss and Channa gachua.
Mirza (2007) reported fishes of whole River Swat. This work was not based on personal
collection rather it was a review of all the work done in this regard previously. He included all
the fish fauna of upper part of River Swat from Mingora to Kalam and lower part of River Swat
downward Mingora upto Charsadda. He reported 45 fish species viz. Onchorhynchus mykiss,

MATERIALS AND METHODS
3.1 Collection of fishesThe whole stretch of River Swat and River Panjkora was divided into different collection zones
considering their ecology and topography. From Kalam to Bahrain was nominated as Zone 1,
from Bahrain to Madyan zone 2, from Madyan to Matta, from Matta to Mingora and so on upto
Charsadda. The same way of collection was also adapted for River Panjkora. All possible efforts
were made to make collection from minor tributaries, streams and khwars and even from iraabs.
Catch efforts were made monthly from June 2011 and continued for the whole year till May
2012. The collection was made with the help of hook and line, semi automatic rod, cast net, hand
net and other locally adapted devices, except poisoning with toxic chemical, dynamiting and
other inhuman, unethical and illegal ways. The size of the mesh used for capturing fish was in
range of 0.6mm to 2.2cm. This is why the collection included small size fishes like Puntius and
Barilius as well as large size fishes like Schizothorax, Racoma, etc.
A big collection of fishes from River Swat was present in fisheries lab made by research
students of Department of Zoology, University of Peshawar. This collection was also utilized
and considered for the present studies.
32
3.2 Preservation of fish
Fishes thus caught alive were killed by a hit on the head and was then immediately
preserved 5 % formalin solution. 20 parts of water were mixed with one part of commercial
formalin (37%) to make above solution. The solution was kept in plastic bottles. Fishes were
dropped into bottles and lids were placed. The above procedure assists in identification.
3.3 Formalin InjectionsFishes with length 15 cm or more were injected with formalin through a hypodermic syringe in
their belly with full pressure of the thumb on syringe so as to spread the chemical in the whole
viscera. This process keeps the preserved fish from decay by stopping bacterial infection from
inside.
33
3.4 Caring the collectionThe fishes preserved, were shifted to laboratory. Every bottle/jar was labeled mentioning
collection locality, date and time.
3.5 Measurement and laboratory work Prior to identification, each fish was taken out from the bottle with the help of forceps and was
placed in a petri dish. The specimen was washed with tap water for 2-3 minutes.
At first fish was identified by inspection method which generally works in most cases upto genus
level identification.
Then meristic counts and Morphometric characters were measured, and fishes were identified up
to specie level.
Vernier caliper and ruler were used to take various morphometric measurements. During lab
work instruments like magnifying glass of different focal lengths, forceps, counting needles,
divider, light microscope, binocular microscope, dissecting microscope, surgical gloves, and
Petri-dishes were used.
3.6 Procedure for IdentificationFollowing Morphometric measurements were taken as described by Ali (2012)
a. Total length
b. Standard length
c. Forked length
d. Pre dorsal length
e. Post dorsal length
f. Lateral line scales
g. Snout length
34
h. Post orbital length
i. Body depth
j. Eye diameter
k. Length of caudal peduncle
l. Meristic count
3.7 ClassificationClassification of fishes was made using various taxonomic or systematic keys.
Fishes were identified according for their scientific names which followed the taxonomist
name who first described it. This identification according to binomial nomenclature is a
method of uniform identification which is understandable all over the world. For this
purpose, following standard keys were used:
1. Inland fishes of India and adjacent countries. Talwar. & Jhingran. (1991).
2. The freshwater fishes of the Indian region. Jayaram (1999).
3. Fishes of the Punjab Pakistan. Lahore. Mirza. & Sandhu (2007).
4. Pakistan May Taza Pani Ki Machliyan (1st ed.). Mirza (1990).
5. Pakistan May Taza Pani Ki Machliyan (2nd ed.). Mirza (2004).
6. Natural History of Fishes and Systematics of freshwater Fishes of India (Munshi
& Srivastava (1988).
8. Fishes of the World (Nelson, 1994, 2006, 2016)
3.8 Confirmation of ClassificationFinally, the identification was confirmed by paying regular visits to the two most
renowned fish taxonomists; Prof. (R) Dr. Mohammad Ramzan Mirza, GC, Lahore and
Dr. Ajaz Ahmad Sandhu, Professor, GPGC, Gujranwala.

3.9 Development of KeyAnalyzing all the data a most recent identification key was developed. The key provides
the detailed morphometric characters of all the type specimens. This key contains coloured
pictures of all the fishes which make it more valuable and unique from all the other keys
published in Pakistan and India.

RESULTS
Fish fauna of River Swat was studied from Kalam, situated in Upper Swat to Charsadda
where this river joins with River Kabul losing its identity to make River Indus, one of the largest
rivers of not only Pakistan but of Asia as well.
The collection of fish was identified using many published papers helpful in this regard and
standard keys. After identification of fishes a most recent Pictorial Key was developed. The key
and details of individual species along with their classification, morphometric measurements, fin
formulae, general characters like colour, size, habitat and distribution in Pakistan as well as in
other countries of Asia are presented here.

4.3 General Description of Fish Species
4.3.1 ORDER CYPRINIFORMES Mouth is always without teeth and mostly protractile.
Barbels may present or absent.
Dorsal fin is comprised of soft divided or branched rays, but anterior rays (one or more)
are generally unbranched and in many species first simple ray is ossified to make a
spine. Sine may bear either weak or strong serrations.
Adipose dorsal fin absent (except in some cobitids).
Pelvic fins always abdominal.
Head is always scaleless. Body enwrapped with cycloid scales. It is very rare that a
cyprinidis either partially or completely devioid of scales.
A completelLateral line is present in all species.
Branchiostegal rays always three.
All species are oviparous.
This is the largest order of the freshwater fishes which includes 3268 species (Nelson,
2016).
The group consists solely of freshwater fish and is widespread in tropical and temperate
waters of Europe, Africa, Asia and North America.
The greatest diversity is in South-Eastern Asia.
Cypriniforms fishes are very famous as aquarium fishes e.g. loaches and minnows.

4.3.2 Order: SILURIFORMES (Catfishes)
Body elongated and usually dorso ventrally compressed, scales mostly absent or some
may be having bony plates.
Eyes are mostly small as they use barbels in searching food.
Maxilla usually rudimentary and serve as a support for a barbel.
A spine is present in dorsal and pectoral fins (first ray). No spine in pelvic fin.
An adipose dorsal fin, posterior to 1st dorsal is usually present.
Pectoral fins are attached low.
Caudal fin rays mostly 17 or in few cases 18.
Branchiostegal rays are 4 to 17 in number.
Catfishes can easily be identified by their usually long barbels extending from sides of
the upper jaw and in some fishes from lower jaw as well.
Catfishes are of great economic importance as sports fish, valued food items and as pet in
tropical aquaria.
These fishes are numerously present in the Indian region and their size range between 3-5
cm.
Most of the species inhabit freshwater only.
Several species of catfishes are known to be venomous (Halstead, 1970). Sharp spines
present in pectorals can cause severe wounds and a poison could be injected which is
produced by epidermal tissue covering the spines and having glandular cells for poison
production.

4.3.4 ORDER CHANIFORMES (Snakeheads)
Body elongate and cylindrical. dorsal and anal fins are long, completely soft-rayed.
Large mouth with toothed jaws and palate.
Eyes placed in anterior-half of head, dorsolateral in position.
Have wider gill-openings but gill membranes confluent with each other but free from
isthmus.
Pelvic fins usually present having six rays. A typical rounded caudal fin.
Ctenoid or cycloid small size scales on the body. Scales present on head are larger as
compared to those present on the body and provided with concentric rings towards their
margin, a few arranged in form of a rosette.
Air bladder elongated, extending almost to caudal peduncle.
Fishes of this family can be recognized by their head shape which resembles with snake.
The snakeheads inhabit mainly permanent shallow, lentic waters (ponds and lakes); the
larger species (Channa marulius) also inhabit rivers and large lakes.
These fishes are air-breathers. They live for many hours (and sometimes days) out of
water and can migrate across land from one freshwater pool to another.
These fishes can be kept alive for days with the minimum quantity of water, or even if the
respiratory apparatus and the body are kept moist.
All are carnivorous: These fishes are monogamous and great parental care is exercised by
the various species.

Discussion
River Swat is an important river of Khyber Pakhtunkhwa province as well as of Pakistan.
It has a very long stretch of about 250 Km from its origin in the lofty mountains of Chitral and
Kalam to its confluence with River Kabul at Nisatta in District Charsaddah. It is a unique water
body to have a great diversity of temperature regimes from very cold to warm. Its water
temperature fluctuates from below freezing point to 350 C. Similarly, its topography is also
greatly variable from very high mountains to hilly areas and then a run in plain areas. Bottom
conditions too vary a lot from rocky, pebbly and gravelly bottom conditions to sandy bottom in
plain area.
These diverse environmental and topographical conditions have made this river a heaven
for the animal diversity including fish. It is clear from the fact that about a total of 95 fish species
have been reported from Khyber Pakhtunkhwa (Butt, 1986; Mirza, 2007;) out of which 62
(65.2%) species are found in River Swat. Mirza and Bhatti (1999) had reported 179 fish species
and Sandhu (2017) has reported 195 fish species from all over Pakistan. If we compare the
ichthyodiversity of River Swat with the ichthyodiversity of Pakistan, it is about 32% of the total
fish diversity of Pakistan which shows how much diverse are the fish fauna of river Swat.
To completely identify the fish fauna of this river efforts have been made since 19 th
century when McCleland (1842) described the fish fauna of the River Swat for the first time.
Prof. Dr. Muhammad Ramzan Mirza from Govt College Lahore who has published more than
200 research papers on fish diversity of different water bodies of Pakistan, has also started his
work from investigating the fauna of river swat. His first study was about the taxonomy of the
hill stream fishes of Swat and Kaghan (Mirza, 1962).
171
Present work is also a continuation of this chain of research work in which not only the
fishes were collected from the whole length of this river but after their identification a pictorial
key has been developed for identification of those species.
During present work fishes which were collected from upper part of River Swat were
Triplophysa microps, Triplophysa naziri, Schistura alepidota, Schistura prashari, Schistura
curtistigma, Crossocheilus diplocheilus, Carassius auratus, Cyprinus carpio, Garra gotyla,
Glyptosternon reticulatum, Glyptosternon maculatum, Schizothorax plagiostomus, Schizothorax
esocinus, Orienus plagiostomus, Racoma labiata, Acanthocobitis botia, Oncorhynchus mykiss,
Salmo trutta fario, Puntius conchonius, Barilius pakistanicus, Bariliu modestus, Barilius
naseeri, Barilius vagra and Labeo calbasu ( Table 4.7).
Most of the fish species present in the upper region are similar to fauna of lower swat like
Triplophysa microps, Schistura alepidota, Schistura prashari, Schistura curtistigma,
Crossocheilus diplocheilus, Carassius auratus, Garra gotyla, Schizothorax plagiostomus
Schizothorax esocinus, Orienus plagiostomus, Racoma labiata, Acanthocobitis botia, Puntius
conchonius, Barilius pakistanicus, Barilius naseeri, Barilius vagra and Labeo calbasu but fishes
like Barilius naseeri, Oncorhynchus mykiss, Salmo trutta fario, Glyptosternon maculatum and
Glyptosternon reticulatum are only confined to upper river Swat as these fishes can survive in
very highly oxygenated cold water. This is in agreement with many authors (Nelson, 2016; Ali,
2012; Mirza, 2007;) who have confirmed the presence of trouts only in very cold waters.
Glyptosternon is also confined to upper cold regime of River Swat although one specimen was
found from Matta (Hasan et al., 2013) in a perineal tributary in a collection in 2010. It was
considered that the fish had started expanding its range of distribution, but it was never found
172
again in this area in following collections. It seems that the fish might had brought by strong
flood downstream and was surviving in some way.
In the present study an effort was made to collect all possible fish species from the whole
stretch of River Swat. According to the results, fauna comprised of seven orders, eleven families,
38 genera and 62 species (Table 4.2). Order Cypriniforms was proved to be the largest groups of
fishes with two families and nine sub families. About 64.5% fish species belong to this order in
present study (Fig. 4.63). This is the same observation as described by Munshi and Srivastava
(1988), Talwar and Jhingran (1991) and recently Nelson (2016) for the whole Indian region.
The orders which are least common (1.6% species diversity) are Mastacembeliformes and
Beloniformes as they were represented by only a single species each. Ishaq et al (2014) has also
presented the similar information about River Swat.
As for as the diversity of families is concerned the maximum diversity lies in order
Siluriformes which is represented by three families (27.3%) in River Swat namely Sisoridae,
Bagridae and Schilbidae whereas order Cypriniformes is represented only by two families
(18.2%) i.e. Cyprinidae and Nemacheilidae. This is a unique observation because most
researchers have described former as most diverse order in all respects (Akhtar et al., 2014;
Ishaq et al., 2014). One of the reasons might be the low temperature of the water here which
support silurids (catfishes) more as compared to cyprinids. Another reason might lie in the
feeding habits of the fishes as most catfishes are carnivorous and cold waters generally do not
have high productivity and hence can’t support herbivorous fishes which are more represented in
Cypriniforms.
Statistical analysis of the diversity data of River Swat shows that it has a very high
diversity. Values of diversity indices like Simpson’s diversity index ( D= 0.058), Simpson
173
Dominance index (0.942) and Simpson Reciprocal Index (17.34) show a very high fish diversity
both in terms of richness and evenness. Similarly, Shannon Index is a measure of evenness and
abundance. Its value (4.62) confirms the high and evenly distributed fish diversity in River Swat.
Wahab and Yousafzai (2017) reported 10 cyprinids from River Panjkora, a major
tributary of River Swat, including Barilius vagra, B. pakistanicus, Garra gotyla, Tor putitora,
Crossocheilus diplocheilus, Schizothorax esocinus, S. labiatus, S. plagiostomus, Cyprinus carpio
and Carassius auratus. In present study 25 species have been reported from River Panjkora
(Table 4.3). Although Carassius auratus is found in River Swat but in Panjkora it was not found
in present study. Similarly, presence of Schizothorax labiatus is in doubt as no one has reported
it earlier from Pakistan. It might have been confused/missed with Racoma labiata. Hence the
presence of Schizothorax plagiostomus as most abundant species is similar to the present study.
Some fish species in River Swat are of special taxonomic interest like that of Indus
Golden Mahasher Tor putitora and Tor macrolepis. These two species are very similar and fish
taxonomists have questions about their status. The seasoned and most renowned taxonomist Prof.
Dr. M. Ramzan Mirza considers it Tor macrolepis (Mirza and Sandhu, 2007; Sandhu and
Ambreen, 2017) whereas Director, Pakistan Museum of Natural History (PMNH), Dr. M. Rafiq
describes the species as Tor putitora (Rafiq and Javed, 2002). As for as the species’ morphology
is concerned it is generally very difficult to differentiate as the minor difference between the two
is only in the count of lateral line scales. In Azad Kashmir an identification work has been done
at molecular level (Khaliq et al., 2015) to decide the status of golden Mahasher but it remained
indecisive as they had analyzed only one gene which doesn’t gave clear idea about the
classification.
174
Comparison of the diversity of River Swat with other big rivers of the area was also an
aim of the present study. Although River Panjkora is a tributary of River Swat but it itself is
quite a big river with a reasonable fish diversity. Its fish diversity (Table 4.3) is very pronounced
and 25 fish species have been reported so far from this river and its tributaries (Hasan et al.,
2015). River Punjkora shares all the fish species with River Swat except Cyprinion watsoni
which belongs to family Cyprinidae, sub family Cyprininae and it seems to be restricted in this
river. However, sub family Barbinae is present in River Panjkora as Cyprinus carpio is found
here. The reason of its absence from River Swat might be the difference in environmental
factors and topography but actual reasons need to be investigated in future studies.
River Kabul is another big river of Khyber Pakhtunkhwa, Pakistan. Its total length is 700
Km out of which 560 Km flows in Afghanistan. Two recent works have been done to investigate
the ichthyofauna of River Kabul by Khattak et al (2015) and Suleman et al (2016). Former have
reported 25 species and later 22 species most of which are overlapping. Comparison shows that
most of the fish fauna is similar to that of River Swat except for eight species which are unique
to River Kabul and are not present in River Swat. Among them Hypophthalmicthys molitrix and
Labeo rohita belong to family Cyprinidae whereas four fishes Ompak bimaculatus, Wallago attu,
Separata sarwari and Bagarius bagarius belong to family Siluridae. A single species each from
family Cobitidae and family Heteropneustidae is also found namely Botia birdi and
Heteropneustes fossilis respectively. This alteration is due to great difference in ecology of both
the rivers. Not only temperature but bottom conditions, water flow speed, water volume, oxygen
contents, CO2 level, turbidity, minerals etc. are different between these rivers.
175
Floods are natural catastrophes which cause major changes in all environmental factors
which in turn affect the organisms living in the aquatic ecosystem (Godlewska et al., 2003).
During flooding, young fishes generally die in large number because flooding season follows
breeding seasons of most warm water fish (Nehring and Miller, 1987). Therefore, young fishes
are susceptible to damage in floods as their swimming capacity is poor and size is too small
(Harvey, 1987). River Swat has also faced the highest flood in the history in July, 2010. Water
discharge reached 355,000 cusecs (Akhtar et al., 2014) and the whole of KP province suffered
major physical and economic loses.
In the present study some species loss was also observed after the mighty flood.
Collection made in 2011 and afterward depicts that some species which were reported earlier
were missing in the River Swat after flooding. Among them a cyprinid of the subfamily
Cultrinae Chela cachius is a beautiful fish which has been lost now.
Mirza (2007) has reported Naziritor zhobensis but this fish has not been collected from
any part of River Swat again neither before flooding nor after. It seems that the fish was reported
from this area by mistake. Although during other projects my students have captured it from
River Kurram, from North Waziristan and from South Waziristan in last three years which have
a connection with River Zhob and its catch from Waziristan shows that fish has started
expanding its area of distribution downstream.
Mirza (2007), from lower swat and Rafiq and Javed (2002), from Mingora have reported
Schizopyge esocinus/ Schizothorax esocinus from this river. This fish was present in very little
number and only two specimens from Barikot were collected before flooding but now it has not
been caught in any catch. It seems this very important edible species has been lost due to damage
to its habitat.
176
Schistura naseeri and Triplophysa choprai have also been reported from upper River
Swat (Mirza, 2007; Rafiq and Javed, 2002) and many specimens were collected from Barikot
and Chakdara by me in 2004 but now these species seems to be eliminated from this river as they
are not present in catches after floods.
Three species of family Siluridae namely Glyptothorax sufii, Glyptothorax cavia and
Glyptothorax naziri were reported by previous workers from River Swat and were also collected
by one of my students but after the floods of 2010 they are not present in any catch. Similarly,
Xenentodon cancilla (family Belonidae) was collected in 2004 but after floods it has been
disappeared from the river.
Two very beautiful ornamental fishes of family Belontidae namely Colisa faciata and
Colisa lalia were reported by Mirza (2007) from below Mingora i.e. lower part of River Swat but
they are no more present in the river now. Being very small in size and delicate in nature these
beautiful aquarium fishes are no more present. Flood deposits heaps of alluvial soil which might
have completely damaged the breeding grounds of these valuable ornamental species.
Fish is a gift from nature and nutritionally and medicinally it is very important for human
health. Its meat is very digestible (about 85%) and 379 grams of common carp’s flesh contains
approximately 9.25 grams of Nitrogen (lagler et al., 1962). In other words, we require about 410
grams of Fish flesh for obtaining 10 grams proteins. In present study it was observed that some
of the fishes are edible and some are nonedible. Although all the fishes are edible but generally
in Pakistan people don’t like to eat small sized fish (Haq et al., 2014). Amongst the fishes
reported from River Swat 16 species (Table 4.5) which means 25.8% of the total diversity (Fig.
4.66) can be classified as major edible species as they grow to marketable size which people like
177
to buy and eat. These fishes include Labeo calbasu, Labeo diplostomus, Cirrhinus mrigala, Tor
putitora, Tor macrolepis, Schizopyge/Shizothorax esocinus, Orienus plagiostomus, Racoma
labiata, Cyprinus carpio, Ctenopharyngodon Idella, Oncorhynchus mykiss, Salmo trutta fario,
Clupisoma garua, Clupisoma naziri, Eutropiicthys vacha and Mastacembelus armatus.
There are some other fishes which are generally considered non- edible due to their small
size but still in some areas people like to eat them because of their very soft flesh. As these fishes
are of small size, they are eaten as a whole and have high nutritional value (Table 4.6). People
consider their meat sweater and soft. These fishes include 13 species viz. Cyprinion watsoni,
Naziritor zhobensis, Crossocheilus diplocheilus, Garra gotyla, Carassius auratus, five species of
genus Glyptothorax, two species of genus Glyptosternon and Mystus bleekri. These species make
about 21% of the total fishes of the area (Fig.4.66). It is quite clear that the river has a great
economic potential as almost half of the fish species are edible and could solve the issue of the
protein deficiency and food security which are major issues of the third world countries.
Some fishes especially from genera like Chela, Salmophasia, Salmostoma,
Barilius, Aspidoparia, Devario, Rasbora, Puntius, Schistura, Triplophysa, Acanthocobitis,
Carassius, Cyprinus (coloured varieties), Gagata, Chanda and Colisa are really very beautiful and
could be kept in aquaria (Table 4.1). Aquarium fishes is a big business throughout the world
which was started in Sri lanka (Rao et al., 2013). The trade of ornamental fish is composed of
about 1450 marine fish species and about 4500 freshwater fish species (Alam et al., 2016;
Ahmad,1996). Pakistan is a big importer of ornamental fishes where main markets are located in
big cities like Karachi, Lahore, Islamabad, Faisalabad, Peshawar etc. In Pakistan even, those
species are imported which are found in our waters (Bakhtzada, 2016). As mentioned above 18
genera of aquarium fishes exist in River Swat which if properly managed and harvested could
178
become a big economic activity for the poor people of the area. These fishes could be cultured or
artificially bred and could become a permanent source of income for the public.
Another important issue, although not directly related with the scope of the present study,
is one of the important reasons in fish decline and species loss is illegal and inhuman fishing
methods like poisoning, dynamiting, electrofishing and fishing in local utensils and Jals (nets)
have adverse impact on fish fauna. The above practices affect the water quality and river ecology
and in response disturb the livelihood, social and economic conditions of the community. In
some places the young boys stop water in channels made for irrigation and small streams to catch
fish. This results not only destruction of small fishes in the dried stream but a greater loss to
aquatic creatures. Stopping of water in irrigation canals also causes the destruction of breeding
ground of most of the fishes. The number of brooder fish has been reduced in the river because
of high fishing, therefore, catching undersized fish may be an additional factor in vanishing fish
population. Due to all these factors, “Tor putitora and T. macrolepis” (Mahseers) and
“Schizothorax esocinus” (Thalk) are near to extinction in the river. This is the same observation
made by Ali et al (2010) that Schizothoracines and Mahseer are becoming rarer because of over-
fishing and spawning grounds destruction.
Conclusion
The present study on River Swat concludes that the river keeps a very favourable
set of environmental factors and is supporting a great diversity of fish. Its ichthyodiversity is
highest if compared with other rivers of the province. However, historical flood in 2010,
pollution and habitat loss are causing stress on fish and other aquatic fauna and some species
have apparently disappeared from the river.
179
It is also concluded that the river has a great impact on the economy of the people of the area not
only in terms of irrigation and household utilization but for having a great variety of edible and
ornamental fish species which, if properly managed and utilized, can change the destiny of the
people of the area.
Recommendations
1. Aquaculture is not well developed in the swat. The activities are only present for
Mahasheer culture in Thana and Trout culture in upper part of Swat district. The fish
farming activities are limited in the area. Local people are interested in making fish farm
for additional income generation, but they neither have any guidance nor encouragement
and motivation.
2. To ensure the conservation of natural fish resources Hatcheries for local fish species need
to be developed. These hatcheries may provide seed to local fish farmer as well as stock
in natural water resources.
3. Professional fishermen should be given proper training by fisheries department.
4. Seminars and workshops should also be arranged in schools, colleges and universities to
aware teachers and students about the importance of fish, and their conservation.
5. Laws promulgated for fish conservation need refinement and their implementation in true
spirit is needed.
6. Public walks should be arranged to motivate the people for fish and biodiversity
conservation.
7. Existing management plans for fish reserves need reconsideration as the previous ones
are badly failed.
180
8. Local people and communities need to be involved in the fish management and
conservation strategies for future.
9. Laws to control illegal fishing and use of cruel methods should be updated and with high
penalties more strong law enforcement is required.
10. Total and effective ban on fishing during breeding season should be implemented.
11. Standard size nets should be used to minimize the risk of undersized fish being caught in
the net.
12. Effort for recapitulation of endangered and critical fish species like Mahseer “Tor
macrolepis” and Thalk “Schizothorax esocinus” should be made.
13. Research centers and restocking centers like hatcheries are recommended in Swat for
endangered fish species to ensure their conservation.
14. Water pollution should be controlled to protect the fish habitats destruction.
15. Coordination among government departments, NGOs and law enforcing authorities is
required for the conservation of not only fish fauna but freshwater ecosystem too.
16. Fish taxonomic identification should also be conducted in River Swat based on their
genetics through DNA analysis as future work to overcome the ambiguities in
identification.
