Abstract

The present study was conducted to investigate the comparative effect of Ovaprim and Pituitary gland Extract (PGE) on the induced spawning of Silver carp (H. molitrix) from May to July 2024 at Carp Fish Hatchery University of Peshawar, Khyber Pakhtunkhwa Pakistan. Two pairs of healthy, active and sexually matured brooders were selected and calculated their weight between 750 kg to 2100g. The standard dose for brooders, 2mg/kg Pituitary gland extract (PGE) and 0.25 ml Ovaprim were injected once to male and twice to female after 4-6 hours of the administration of the first dose. The Pituitary gland extract (PGE) response was recorded with an average fertilization rate was 62.09 % and the average fertilization rate of Ovaprim was 75.64%. The present study disclose that the synthetic hormone Ovaprim is more effective and efficient as compared to Pituitary gland extract (PGE).
