Abstract |
Reproductive performance of Heterobranchus bidorsalis was assessed over 8 weeks feeding experiment. The feeding regimes (starved {control}, 2 and 4% body weight/day, and satiation) were involved and replicated thrice. Gonad weight (GW), oocyte weight (OW) and gonadosomatic index (GSI) increased as the rearing period increased. There was a significant difference (P<0.05) in the relative fecundity (RF), GW, OW, GSI, % fertilisation, % hatchability, % deformation and progeny survival of control and fed treatments. Best results were achieved at 2% body weight/day (bw/d). |
