4. Pond Management
 Monitor your fish ponds
regularly.
 You can also judge how
well supplementary feeds
are being utilized and how
fast your fish are growing.
 you can plan the
stocking, transfer, and
harvesting of your fish.

5. Steps of pond preparation
Draining and Drying
Fertilization
Soil Conditioning

6. Draining and Drying
Ponds should be dried for 7-10
days till the soil cracks the ponds
with clayey soil, in sandy soils,
they should be dried till the soil
supports a person and footprints
do not form on the soil.

7. Fertilization
 Fertilization of a fish pond actually
increases the production of beneficial
phytoplankton.
 By increasing the phytoplankton
in a pond, more food items are
available for smaller fish

8. Soil conditioning
Adding organic matter in the
form of compost, manure, or
readily available materials
like coffee grounds is a reliable
means of improving soil quality.

9. UVAS fish hatchery
A fish hatchery is a place for artificial breeding,
hatching, and rearing through the early life stages of
animals—finfish and shellfish in particular.

10. Importance of Fish Hatchery
Hatcheries provide the seed for aquaculture and some
commercial fisheries. All kinds of fish and shellfish
begin life in tanks in a hatchery. A hatchery is a mix of a
laboratory and a farm, where fish and shellfish are
spawned, then hatched and cared for.
Function of Fish Hatchery
A hatchery is a facility where eggs are hatched under
artificial conditions.

11. Types of Tanks in UVAS Fish
Hatchery
They have two types of tanks in the UVAS fish hatchery,
 One is circular tanks
 The second is rectangular tanks

12. Induce breeding
Induced breeding is the technique where the fish
breeders use the pituitary hormone to ripe the fish.
This stimulation results in a timely release of sperms
and eggs from the ripe fishes.
 Induced breeding can also be called artificial breeding.
The gonadotropin hormones are used in induced
breeding.

14. Steps of induced breeding technique
The following steps of inducing breeding technique,
Collection of Pituitary Extract
Brooders Selection
Injection to the Brooders
Spawning

15. Brooders Selection
 Medium-sized fully ripe and healthy fish is
preferred for breeding.
 Age 2 to 4 years.
 The weight should be 1 to 5 kg.
 Healthy male and female breeders should be
identified.
 They should be provided with supplementary food
with high protein.

17. Injection to the Brooders
 Insert the needle between the pelvic fin and the
anal fine.
 Both males and females were injected with
ovaprim.
 Male injected 0.2 ml/kg body weight.
 Female injected 0.4 ml/kg body weight.

19. Spawning
Males and females were released into respective
circular spawning tanks at Suitable temperatures.
 The tank was covered with a net to prevent the escape
of fish.
Males and females were observed with an interval of
half an hour regularly till oozing out of eggs.

21. Stripping
The female started releasing eggs.
It was netted out with the help of a hand net.
Clean with a dry towel.
The female belly was pressed and the eggs were
collected in the clean dry tub.
After stripping the female, the male was captured and
the milt was sprayed on the eggs by pressing its belly.
Eggs and milt were thoroughly mixed with bird
feathers for 3-4 minutes.
Then water was slowly added to the tub.
Then a separate clean circular tank was filled with
fresh clean water, and release the egg.

24. Name of different carps breeding at
UVAS fish hatchery
The following carps breeding in uvas fish hatchery,
 Silver Carp
Thala
Rohu
Grass carp

25. First trail Silver carp

26. Second trail Thala

27. Third trail Rohu

28. Forth trial Grass carp in Sandhua
fish hatchery

29. Examination of egg developmental
stages
Eggs were collected at different time intervals from the
incubation tank.
These eggs were observed under a microscope.
