ABSTRACT: Boal fish or Indian major catfish are generally available in large river, swamps and freshwater lakes but now-a-days those natural habitats are severely degraded. This decreasing rate of Boal fish can be reduced through natural restoration, and breeding practices should be increased. This is the first attempt to breeding Boal fish through hormone-induced breeding by stripping in Bangladesh. The ovulation and fertilization rate was found 90% - 95% and 75% - 85%. Unfortunately, after the gastrula stage, embryogenesis success can be affected by various factors like water quality and handling of larvae. This encouraging finding of preliminary success will motivate researcher to work on brood management, improvement and/or perfection of induced breeding techniques, larval food and rearing, and mass seed production.
