In the present study, intramuscular injection of ovaprim-C was studied on the number of eggs/kg, fertilization rate and hatching percentage during April to August 2015 at Punjab Fish and Seed Hatchery Rawal Town Islamabad on Silver carp (Hypophthalmichthys molitrix) and Grass carp (Ctenopharyngodon idella). Fishes were spawned successfully following a single dose of injection of ovaprim-C (luteinizing hormone releasing hormone analogue) with 0.5 ml/kg for female and 0.1 ml/kg for male. Experiment was conducted in circular spawning tank. The results showed successful spawning of both fish species silver carp (Hypophthalmichthys molitrix) and Grass carp (Ctenopharyngodon idella) with the constant dose of ovaprim in captivity which was found to be fruitful for commercial scale fish production and we conclude that ovaprim proved the advantages over other commercial pituitary and not it reduces the brood handling problems but also reduces the post spawning mortality of fish as for as it increases spawning response too.
