Captive Breeding of an Endemic Medium Carp Pengba, <i>Osteobrama belangeri </i> (Val.) With Wova-FH in Manipur

Abstract

Induced breeding of the endemic medium carp, Osteobrama belangeri (Val.) was conducted using synthetic hormone Wova-FH in three doses @ 0.3, 0.5, 0.7 ml/kg to female and 0.1, 0.2 and 0.3 ml/kg to male body weight in groups A, B and C, respectively. The male and female brooders were injected and left to spawn in the breeding hapas at 2:1 ratio. It was found that Wova-FH could induce the fishes to breed, whereas no breeding was observed in control set. The latency period was found to be 7-8 hours. The egg output/female with Wova-FH at a dose of 0.5 ml/kg of female and 0.2 ml/kg of male body weight in group B was significantly higher (P<0.05) than groups A and C. A female of 250 g could produce 55,000-65,000 eggs by induced breeding. Fertilization and hatching rates of 91.7 and 85% respectively, with Wova-FH dose of 0.5 ml/kg of female and 0.2 ml/kg of male body weight was found to be significantly higher (P<0.05) than the other doses.
