The present study was conducted to investigate the induced spawning of Grass carp (Ctenopharyngodon idella) and Rohu (Labeo rohita) from April to June 2013 at Carp Fish Hatchery Char Banda District Mardan (Khyber Pakhtunkhwa). The weight of brooder fishes was calculated between 2 kg to 4 kg. The fish response was compared between PGE and synthetic Ovaprim. The standard dose for both PGE and synthetic Ovaprim was injected to each brooder and the ovulation period was noted. The PGE response in Grass carp (Ctenopharyngodon idella) was recorded with an average fertilization rate of 53.36 % and in Rohu (Labeo rohita) a fertilization rate of 75 %, respectively. The fertilization rate of Ovaprim in all fishes remained the same as 86.3%. This study revealed that the synthetic Ovaprim response is more effective as compared to PGE.
