Transport the zygote to the Zog Transport the zygote to the Zog jars: jars:

1. But between (150-200g) zygote for each zog jar.

2. But gradually zygote inside zog jar quit after full zog jar to the half by water.

3. Determine interred water flow rate to zog jar slowly for the first (12) hours.

4. increase water flow rate (1-2) liter/minute.

5. Another types of carp differ from egg quantity (50-70g) of egg for each zog jars with decrease water flow rate to the minimum value.

6. disinfect the eggs by malachite green one time after (12) hours and stop in when egg hatching start.

Egg hatching period:Egg hatching period:1. Egg still in zog jars between (3-5)

days according to the water temp.2. Looking after the eggs for exiting

the destroyed eggs. 3. Disinfect the egg by malachite green

twice a day (daily & nightly).4. You can see the fry at the zog jar

sides.

Fry transporting to dry nurse Fry transporting to dry nurse (incubator):(incubator):

1. Fry hatch in the incubator for 24 hours without artificial feeding because this fry depend on yolk sac for feeding.

2. Put between (400-500) fry for each incubator. 3. Fry feeds artificially when they can swim horizontally.

Fry feeding inside incubators:Fry feeding inside incubators:1. Fry feeds on emulsifyلوقDبيض المسDفار الDتحلب صDمس of boiled egg.2. One Egg yolk enough for two incubators.3. Feeding continue one time over (4) four hours for (3) three

days.

Ground ponds preparing for fry Ground ponds preparing for fry culture:culture:

1. before fry culture check pond inlet and outlet for leaking.

2. Check for a while before fry transfer to avoid aquatic organisms & insects grows which harm fry.

3. Gradually increase pond depth to (50-70cm).

4. Preferring fry culture in cages to easy control it.

5. The quantity of water must be increase after (10-15) days.

Fry feeding in ponds:Fry feeding in ponds:1. Fry feeds on soybean emulsify

on the first days.2. Emulsify quantity about

(5mg/1 million fry).3. Emulsify quantity increased

after three days.4. After (20) days of culture, fry

weighing (0.5-1g) feeds on ground brew diet.

5. When fry reach (0.5-1g) weight prefer to transport it to another big ponds with low density for marketing purpose.

Continue growing process:Continue growing process:1. Fishing the fish & record growth rate by recording length &

width.2. Re-record these measurements to know the grow increase to

determined the enough diet.3. Analyze the physical & chemical parameters of water such

as temperature, pH & oxygen.4. These processes must done before and after fry culture and

continue daily.
