Efficacy of Dry Pituitary Gland, Wet Pituitary Gland and the Synthetic Hormone Ovaprim on Labeo catla Breeding

An induced breeding experiment with Indian major carp, catla (Labeo catla) was conducted to know the efficacies of three different doses dry Pituitary gland and wet in comparison that ovaprim. Intra- peritoneal injections were given at base pelvic fin PG low dose (DPL), 1 mg/Kg body weight for first female fish after 6 hours interval second (2 weight) administered; same time male. For medium (DPM), 2 six 4 high (DPH), 3 male fish. Wet (WPL), 7 10 (WPM), 11 15 And (WPH), 20 ovaprim, 0.25ml/kg 0.5 ml/Kg single respectively. These used determination fertilization, hatching survival rates. The fertilization rates 83.25 ± 0.85%, 92.01 0.45%, 82.45 1.04%, 83.18 0.68%, 88.59 0.48% 72.85 0.43% DPL, DPM, DPH, WPL, WPM ovaprim 78.58 0.94%, 85.54 0.38%, 74.8 0.22%, 77.89 0.82%, 81.56 0.59% 71.54 respectively 77.24 0.49%, 87.12 0.46%, 73.09 0.42%, 75.8 0.30%, 80.76 0.64% 69.2 0.77% Among all synthetic hormone DPM gave best result case rate. So, may use as dose.
