Abstract

In the present study economically important and fast growing food fishes grass carp (Ctenopharyngodon idella)
and silver carp (Hypophthalmichthys molitrix) were successfully spawned with Ovatide (combination of GnRH
analogue with dopamine antagonist pimozide) in Kashmir. The preparations were administered by an intramuscular
injection of single dose of 0.7 and 0.8-0.9 ml/kg body weight for female grass carp and silver carp and a single dose
of 0.35 and 0.4-0.45 ml/kg body wt. body wt. for male fishes respectively. After dosing, the fishes were immediately
carried to breeding pools in the Chinese Hatchery. After 14-16 hours of dosing spawning took place. After 10-12 hours
of spawning, twitching movement started. Hatching occurred after 20-30 hours of fertilization at 24-26°C. Fecundity
of grass carp and silver carp were recorded as 70000- 80000 and 1-1.10 lac eggs/kg body wt. of fish respectively.
The fertilization percentage of grass carp and silver carp were recorded as 80.03% and 78.12% respectively. The
hatching percentage of grass carp and silver carp were recorded as 70.10% and 69.71% respectively. And the fry
survival percentage of grass carp and silver carp were recorded as 15. 21% and 14.56% respectively. The source
of water was Manasbal Lake that favored most of the water quality parameters for spawning, hatching and survival
of fry than ground water.
