It is presentation that gives basic information about induced breeding in carps and moreover it summerise pre- and post stocking managment.

1. “ON BREEDING AND SEED REARING OF
INDIAN MAJOR CARPS”
PRESENTED BY:- SHIVANI VERMA
B.F.SC - IV YEAR
VII SEMESTER
Presentation on in hands on training 2017-18 :-

2. SITE OF WORK/ TRAINING PLACE
AQUACULTURE RESEARCH AND SEED PRODUCTION UNIT, UDAIPUR
1. The Seed Production Unit of MPUAT , Udaipur was started in the year 2002 with the financial assistance from
ICAR under the “Revolving Fund Scheme" .
2. The new farm at new promises was developed with financial assistance of rupees 112 lakh from TAD department
under central sponsored scheme.

3. INFRAStructure of Farm
• Total area of farm = 4 ha.
• Total ponds = 10 cemented + 2 earthen = 12 ponds
• Water source = Tubewell
• Infrastructure facilities :---
• 1) Carp hatchery unit
• 2) Watering facilities
• 3) Brood stock ponds
• 4) Rearing ponds
• 5) Nursery pond
• 6) Office & Laboratory – Fish Biotechnology , Aquaculture,Health management,Wet lab.

4. Biology of Cultivable Fishes
• Bisexual,sexes can be distinguished only during the breeding season.
• All 3 major carps attain sexual maturity in the second year.
• Males mature earlier than female.
• Carps of 2+ year and up to 5 year are preferred for breeding.
• Spawning season – Seasonal riverine spawners , spawning during the
southwest monsoon.
• Why induced breeding ?
• IMC do not spawn in confined waters.
• For the increased production of carp it is necessary that they
should be made to breed in confined water so this can be done by
INDUCED BREEDING TECHNIQUES.
• Synthetic compounds used for IB :- Gonadotropins, OVAPRIM , OVATIDE

5. FISH SEED PRODUCTION TECHNIQUES ADOPTED IN FIELD
INDUCED BREEDING :-
Breeding fish with pituitary gland( hypophysis) extract is tremandous hypophysation. Induced breeding refers to
inducing fish to release gamets through the application of pituitary extract or hormones or chemicals ..
INJECTING THE FISH:-
1. INTRA-MUSCULAR INJECTION:
2. Administration into the muscle on the caudal peduncle or behind the dorsal fin.
But above the lateral line fin.Above the lateral line avoiding the lateral line,
it is most effective convenient,simple and less risky.
2. INTRA-PERITONEAL INJECTION:
It is give through the soft regions of the body,generally at the base of the pelvic fin or the pectoral fin.It is risky
as it may damage the gonads or liver.

7. S.N. Characteristics Male Female
1. Pectoral fin Dorsal surface is
rough
Dorsal surface is
smooth
2. Genital aperture It is not prominent.
Further on pressing
milt oozes out
It is reddish and
swollen. Further on
pressing eggs ooze
out.
3. Shape of belly Not bulgy and soft
to touch .
Belly is soft and
bulgy.
SELECTION OF MALE AND FEMALE BROOD STOCK :
Male and female broodstock were selected by visual examine.
Selection of fish is difficult when that fish is selected second time for breeding, some times belly may be bulgy
due to fat deposition. Main criteria for selection of male and female were given below in table :

8. SEED REARING TECHNIQUES
NURSERY POND MANAGEMENT:-
 PRE-SPAWN STOCKING NURSERY POND MANAGEMENT
a) DEWATERING AND SUN DRYING
b) CONTROL OF PREDATORS

REARING POND MANAGEMENT:-
 PRE-STOCKING MANAGEMENT
ERADICATION OF AQUATIC WEEDS
ERADICATION OF PREDATORY AND WEED FISHES

10. HATCHERY COMPONENTS OF CHIENESE CIRCULAR
HATCHERY
THE CHINESE SPAWNING AND HATCHING SYSTEMS ARE BASED ON CONTINUOUS FLOW OF
