Abstract:
The present paper of breeding performance and larval survival of Cirrhinus mrigala was carried out at two different locations, i.e. Dhaura Reservoir and College of Fisheries, G.B.P.U.A.T. Pantnagar, Uttarakhand from July 2014 to November 2014. For the present investigation 3 types of inducing agents were taken viz. Ovatide, Wova FH and Carp pituitary gland extract. Results obtained from each stimulant were analyzed with the respect to total number of eggs, relative fecundity, percentage of fertilization rate, hatching rate, hatching time and fry survival rate. All parameters were studied and maximum in case of Ovatide induced fishes followed by Wova FH and carp pituitary extract at both Dhaura reservoir and Pantnagar. In the larval rearing period of 140 days at Dhaura reservoir the net weight gain and maximum length gain was maximum in Ovatide. In case of Pantnagar larval rearing the net weight gain was maximum in Ovatide induced fishes while maximum length gain was found in carp pituitary gland extract induced fish. The present study concludes that the Ovatide inducing hormone is effective breeding hormone for fish production.
