Abstract :
Induced breeding of pangas, Pangasianodon hypophthalmus was carried out from May to
August, 2020. The experiment was carried out in the month of May, June, July and August 2020 with
PG and LHRH-A. Two hormonal sources were tested to evaluate their efficacy on ovulation, fertility
and hatching rate of pangas under controlled condition. Double doses of PG (an initial dose of 2.0
mg/kg body weight and final dose of 8.0-10.0 mg/kg body weight) and single dose of Ovuline®
(LHRH-A) (0.50 -0.60 ml/kg body weight) showed better results in case of female. In the month of
June, PG and LHRH-A showed better results in ovulation, fertility and hatching rate. Males were
administered with a single dose of LHRH-A (0.15 ml/kg body weight) and PG (2 mg/kg body weight)
showed better results in spermiation. The hatchery operators may use both PG and LHRH-A for
induction of spawning better performance of P. hypophthalmus breeding.
