Effect of carp PG doses on induced breeding of Shing, Heteropneustes fossilis (Bloch)
Five hormone doses viz. 25, 50, 75, 100, and 125 mg of carp PG/kg of body weight of therecipient fish were tested and they were designated as T1 T2, T3, T4, and T5 respectively.Significantly higher fertilization (98%) and hatching rates (38%) were obtained from T3(75 mg of carp PG extract/kg body weight). While T4 (100 mg of carp PG extract/kg bodyweight) and T5 (125 mg of carp PG extract/kg body weight) gave the highest (90%)ovulation rate. In June and July the highest fertilization rate of 96 and 96.4%respectively and hatching rate 42.5 and 48.7% respectively were obtained. In over allconsideration carp PG extract at a dose of 75 mg/kg body weight appears to be thesuitable dose for induced breeding of H. fossilis and June and July are the suitable timefor its induced breeding.
