Abstract: The performance of various inducing agents in induced breeding of Pangasius pangasius, the catfish, is compared in this study. Three set of brooders were used for treatment of three hormones, during the disquisition. Pituitary gland extract (PGE) was given at a dose of 5 mg/ kg body weight for males and female in low (0.2 mg), medium (0.4 ml) and high (0.6 ml) in three triplicates and same for other two analogues synthetic hormones. In comparison to PGE and ovasis - convinced individualities, breeding success was shown to be advanced in ovatide - treated individualities in this study in all orders, including latency period, ovulation rate, fertilization rate, hatching rate, and incubation length. The latency period was 15 hours for PGE and ovasis given brooders and within 10 hours for ovatide doses individualities. Likewise, the current study showed that using ovatide at a rate of 0.6 ml/ kg body weight of female fishes is more effective than using other breeding hormones in terms of ovulation, fertilization, and hatching rates. The current study's findings will help hatchery directors in overseeing convinced parentage.
