Abstract

The reproductive biology of Catla, an important Indian major carp, plays a crucial role in aquaculture productivity. Controlled hatchery conditions have made large-scale seed production possible through hormonal induction and environmental manipulation. This study reviews key reproductive traits, gonadal development, fecundity, spawning behaviour, and hatchery-based breeding performance of Catla. Data generated from controlled hatchery trials demonstrate high fertilization and hatching success when optimal physico-chemical parameters and brood stock management practices are followed.
