DESIGN OF CARP HATCHERY

Introduction

The most important pre-requisite for the development of fish culture is the

establishment of dependable fish seed resources of commonly cultivable species. The

hatchery is perhaps a vital component in a modern fish farm. It is logical corollary of the

development of induce breeding as a technique for commercial production of carp seed. The

design and construction of hatchery systems require sound technical skills. Very good skill is

required for water quality management. Efficient and economical water filtration and

disinfection system are needed for this. A good design helps to produce healthy seed

economically with ease of operation. The hatchery consists of water quality section, breeding

section and larval rearing section. There should be good coordination between the sections.

The basic requirement for a hatchery is to ascertain the ecological parameters of the

embryonic development of the fish eggs and then to provide them with the most satisfactory

incubation condition. This increases the hatching rate. A hatchery complex not only provides

the facility for spawning and hatching but also provides the facilities for brood stock rearing

and seed rearing to produce stocking material for grow out ponds and other fish production

units.

History

Inspite of natural fish seed production, breeding of fish in ponds in hapa and hatching

of eggs in Earthen pot hatchery, Tub hatchery, Nowgaon type hatchery and in hapa (single

wall, double wall and floating hapa) were the only techniques for spawn production. Later on

improved hatching devices like Glass Jar hatchery, Galvanised hatchery, Shirgur plastic bin

hatchery are being developed and are used for hatching of eggs. In the year 1980, modern

carp hatchery model C.I.F.E. D-80 was designed which was a combined unit for breeding of

fish and hatching of eggs. This model was again improved as D-81 and D-85 with slight

modification. At the same time, Chinese Hatchery/Circular Hatchery came into existence and

are found best hatchery for mass breeding and hatching of fish eggs. Based on Chinese

principles, Eco-hatchery has first been established in West Bengal in 1984. A number of Eco-

hatcheries have since been established in different States of the Country and they are capable

of handling mass quantity of eggs at a time.

Chinese eco-hatchery

Chinese eco-hatchery has been named because it is economic and maintains optimum

ecological parameters during fish breeding and hatching. Within a small space, this system

simulates some aspects of riverine environment and has proved itself to be a very successful

method for large scale production of Indian major carps, minor carps and exotic carps. In

modern times, more and more hatcheries are incorporating circular breeding tanks with

continuous water flow.

Site Selection

A carp hatchery (Chinese hatchery) should be located by the side of a perennial

source of good quality water. There should be adequate water to fill the ponds and maintain

water level which does not fluctuate more than 0.6 meter. Equally important is the need for

avoiding excess water. The common water sources are rivers, streams, springs, canals,

surface run-off from rainfall and the ground water sources. Any of these water would be

suitable provided control of the supply is possible and water is not contaminated.

The topography of the area proposed for construction of the hatchery complex should

generally be flat or gently sloping towards the outlet. The site should be easily approachable

so that no difficulty arises for easy transportation of fish seed. It should also be close to the

source of quality brood fish. The location should have facilities of electricity and

communication. The labour and the materials required for construction and operation of the

hatchery should be easily available at economic rates.

A carp hatchery complex (Chinese hatchery) would generally have the following

units:

1. The brood stock unit for rearing and management of brood stock.

2. The main hatchery unit for spawn production.

3. The nursery unit for raising fry from stocked spawn (4-5 mm to 25-30 mm).

4. The rearing unit for raising fry up to fingerlings (50 mm & above).

5. The packing and marketing unit.

1. The brood Stock unit

The brood stock unit would generally have the ponds, the size of which may vary

from 0.2 -1.0 ha but the preferable size would be of 0.3-0.5 ha and depth of 2.0-2.5 m. for

better management of brood stock, the ponds should have the facilities of water supply and

drainage, so that the desired water level in the pond can be accomplished, if needed. The

bottom of the ponds should be gently sloping towards the outlet. The slopes of the dykes may

generally be 2:1 (2 horizontal : 1 vertical).

2. The main Hatchery unit

The main hatchery unit for spawn production comprises the following essential sub-

units:

i. Water supply

ii. Brood spawning

iii. Egg incubation

iv. Spawn collection

(i) Water supply

The most important requirement of an eco–hatchery is the water supply which can be

accomplished either from a surface water source or from a ground water source.

Most surface water contains fish and other organisms which may attack eggs and

spawn in the hatchery. Some surface water carries suspended solids which may coat eggs and

clog the gills. Filtration of surface water can be accomplished by sand filters which should

filter out particles larger than 0.025 mm size. This will remove most suspended solids

including eggs and parasite. After filtering if the water is at low elevation for use in hatchery

by gravity, it must be lifted to the storage reservoir overhead tank. The reservoir should have

a capacity large enough to serve all hatchery needs for several hours. The reservoir can also

be equipped with an auto water level guard switch to automatically turn electric pump on and

off at pre selected levels.

Ground water (water from open wells/bore wells) is usually free from fish pathogens

and suspended solids and does not require filtering before being pumped into the reservoir.

However, most well water is having low dissolved oxygen (DO) and may contain ferrous

salts. Therefore, for ground water, aeration may be required and the DO content would be at

least 4mg/lt. If water contains ferrous salts, it would be necessary to have two reservoirs. One

can be use, while other acts as a settling tank for precipitation. If needed, water can be aerated

before entering into settling tank. Water take off point for the hatchery should be well above

the bottom of the reservoirs for removing precipitate. The iron content of water should not

exceed 0.2 mg/lit. The water temperature should preferably be 18-27oC, water pH 7.4-8.4

and there should not be any pollution at the source. Since all component parts of the hatchery

are required to be provided with controllable water supply, a very careful attention should be

given for designing the water supply installations.

(ii) Spawning Pool (brood spawning/breeding)

Fig1. Spawning pool showing central outlet

The breeding pool is a circular smooth cistern of brick or R.C.C (Re-enforced

concrete cement) or F.R.P (Fibre Reinforced Plastic) with provisions of showers and water

current in the pond. Diameter of the tank may vary from 6-8 m and depth 1-1.5 m for

standard commercial carp hatchery. Water current in the circular pool is created at a speed of

0.2-0.5 m/sec.

For a breeding pool having inside dimension of 8.00 m diameter, the inside depth at

periphery is 1.20 m which slopes down to the center at 1.50 m. The water supply to the pool

is from overhead tank by means of 7.50 cm diameter pipe. It is provided with inlets, placed

equally at an angle of 45o

in relation to the vertical wall and along the periphery of the bottom

of the tank. All nozzles of the inlet pipes are directed to one side. Water from the overhead

tank passes by gravity down to pipes and ejected through the nozzles. As all the nozzles are

pointing towards the same clockwise side, a circular current of water is created at the tank.

Along the upper margin of the circular tank runs a circular pipe provided with holes at regular

interval. Through these holes the water is ejected and falls on the water surface of the tank

giving the impression of rain. In the center, an outlet pipe of 10.00 cm diameter is fitted,

through which on opening the valve, fertilized eggs along with water are transferred into

incubation pond for hatching.

(iii) Incubation Pool (Egg incubation/hatching pool)

The hatching unit is a double circular smooth cistern of brick or R.C.C or F.R.P

material. For a commercial production unit, the outer chamber diameter ranges from 3-6m

and the inner chamber diameter ranges from 1-1.5 m with a depth of the pool from 1-1.5 m.

Fig 2. Incubation pool showing inner Fig 3. Duck mouth Inlets

Chamber with vertical outlet

For a 4 meter dimension incubation pool, the internal diameter is 3.6 meter and the

inner chamber is constructed at 0.74 meter clear distance from the outer wall. The inner

chamber has sufficient gaps and in these gaps, iron rods are fitted so that the nylon screen

(mesh size-0.3 mm) can be fastened tightly to avoid the passing of hatchlings and spawn from

outer chamber. Based on the running water principle, water enters into the outer chamber by

a series of duck mouth inlets fitted at the bottom and drains out through a screen encircled on

the inner chamber. The central outlet pipe 10 cm diameter being vertically erected maintains

water depth in the incubation chamber. The egg receiving pipe from the breeding pool is

generally fixed at about 0.3 m above the base of the incubation chamber to avail a water

cushion against mechanical injury of eggs.

From the breeding pool, this pond receives water and eggs in the outer chamber while

the excess water is drained through the inner chamber. The spawn along with water flows

from these ponds to spawn collection tank through an outlet pipe. This opening is also used

for complete dewatering of the hatching pool. Water in the hatching pool should flow at the

rate of 0.2 to 0.4 m. per second. Number of incubation pool depends on the requirement.

Usually two incubation pools are constructed for the breeding pool.

Water circulation in the pools

Good circulation of water in the pools is the most important consideration for the

success of eco-hatchery. Proper circulation prevents settling of egg cells, dead animals, etc.

on the bottom of the tank. If they settle at the bottom, the decomposition will be anaerobic

and will form harmful metabolites causing death or encouraging growth of diseases and

parasites. If the particles are kept moving in water in presence of oxygen, then decomposition

is aerobic and the by-products are not harmful.

For eco-hatchery the capacity of the hatching tank is about 5 cubic meters and about

500 litres (60-70 lakhs) eggs can be put for hatching at a time. Initially a flow rate of 2.51/sec

is maintained in the hatchery with circular motion in the tanks. After the embryo are hatched

the water flow rate is increased to 3.51/sec for keeping the hatchlings in floating condition as

their buoyancy reduces and their swimming ability is weak.

(iv) Spawn Receiving tank

After completion of incubation, the spawn is received in a pond of various

dimensions. Rectangular cement tank having inside dimension of 4.00 m X 2.50 m X 1.20 m

can be used for this purpose. This is located at a lower elevation than the incubation pool, so

as to drain out the water from it by gravity. Hooks are fixed in two opposite walls of the tank

for fixing net for collection of spawn. From each of the hatching pool, pipes are provided for

transfer of spawn into the receiving tank where they are collected, measured and transferred

into well prepared nursery tanks for rearing. Over flow pipe maintains water depth and

adequate screen arrangement prevents escape of spawn.

Fig. Spawn receiving tank

Operation

Mature brooders are loaded in the spawning pool for about 4 - 8 hr for conditioning.

At a time 40 kg females and 60 kg males are kept. Water jets are started for circular motion

of the water. After about 8 - 10 hr of inducing hormone spawning takes place. The eggs are

collected from the bottom and transferred to the incubation pools through pipes by opening

the valves. For a breeding pool of 8 m diameter having two incubation pools, one crore of

eggs can be incubated at a time in one operation.

Arrangements are made to circulate the water in the incubation pools. After hatching,

they are allowed to remain till yolksac is absorbed. In four days time the spawn gets ready,

then collected through spawn collection tank and transferred or stocked in well prepared

nursery pond for further rearing till fry stage.

3. The nursery unit

The nursery unit of the hatchery complex is for raising fry from stocked spawn (4-5

mm to 25-30 mm size). Nursery ponds should preferably be small and shallow. Ponds of

0.02-0.06 ha size and 1 m to 1.5 m in depth are generally suitable. Since the culture is for a

very short duration and for about 3 weeks only, the pond should have good water supply and

drainage arrangement, with controlled inlets and outlets so that they can be emptied, dried

and refilled at will. This is for easy and better management.

4. The rearing unit

This unit is for raising fry up to fingerlings (50mm and above). The rearing pond

should be slightly larger but not too deep. Rectangular shaped ponds of 0.06-0.10 ha in size

and 1.5 to 2.0 m in depth are preferred.

5. The packing and marketing unit

In a hatchery complex, a unit for packing and marketing is required so as to facilitate

the seed supply scientifically after due acclimatization and proper oxygen packing in the

polythene bags. This will reduce the transportation and handling mortality leaving a good

name for the hatchery to its customers.

The merits of this type of hatchery are:

I. It produces a better and natural environment for breeders to spawn.

II. In incubation pool, the regularity and uniformity of current leads to uniform

distribution of fry.

III. The fry, because of current are better spread compared to stagnant water where they

tend to concentrate in corners or upstream.

IV. Because of better spread, such tanks can take a greater number of fishes than in other

devices.
