The research work was conducted for induced breeding of Vietnames Koi (Anabas testudineus) using carp PG and Ovaprim hormone at Tasty Fish and Feeds Industries Limited, Melandah, Jamalpur during March to May, 2015. Brood fishes were reared for 4-5 months in the brood rearing pond by providing farn maid artificial feed (containing 32% protein) for maturation before onset of breeding season. Two different hormones as inducing agents PG-PG, and PG-Ovaprim were used for the purpose of A. testudineus breeding in the months of March to May, 2015. In the present experiment, the broods were induced with PG-PG hormone (2 mg PG/ Kg body weight for male and 7 mg PG/Kg body weight for female) and PG-Ovaprim hormone (2 mg PG/Kg for male and 7 ml Ovaprim/Kg for female) were designated as treatments T1 and T2 respectively. Ovulation rates 100%, fertilization rates were 78.11 ± 3.24% and 71.00 ± 3.97%, hatching rates were 70.22 ± 3.40% and 60.89 ± 4.20% and survival rates were 51.22 ± 3.96% and 48.89 ± 4.41% in T1 and T2 respectively. The highest fertilization rate (78.11%), hatching rate (70.22%) and survival rate (51.22%) were found in the T1. Comparing the PG-PG and PG-Ovaprim doses, the highest breeding performance was observed in PG-PG dose.
