    Abstract

    Farm reared pengba, Osteobrama belangeri were induced to spawn in captivity during August, 2012 by injecting three different synthetic hormones, Ovaprim, Ovatide and Gonopro-FH. Single dose (1 ml kg-1 body weight) of each hormone was administered and results were recorded. Spawning was observed within 8 h after injection. Hatching of eggs were observed after 22±2 h of incubation at 27±1OC. The mean fertilization rate was 84.05±0.36% for Ovaprim, 79.17±3.95% for Ovatide and 84.85±0.89% for Gonopro-FH treated fish. The mean hatching rate was 84.69±1.73% with Ovaprim, 75.01±1.92% with Ovatide and 86.52±0.88% with Gonopro-FH. Gonopro-FH and Ovaprim gave 5.67 and 4.88% higher fertilization rate as well as 11.5 and 9.69% more hatching rate of eggs respectively as compared to Ovatide. Ovaprim and Gonopro-FH were found to be more effective in induced breeding of O. belangeri.
