This study investigates the reproductive seasonality variation in Indian Major Carps (IMC), specifically Rohu (Labeo rohita) and Catla (Labeo catla). Utilizing field observations and analysis of gonadosomatic index (GSI), distinct reproductive patterns were observed among these species. The findings highlight that, in the absence of scientific interventions such as photoperiod manipulation and feeding management, a significant portion of Rohu and Catla fish reach maturity and breed after and before monsoon period (December and March). Understanding these reproductive variations is crucial for the identification of genetically distinct stocks suitable for line development that can reproduce during the winter seasons. This knowledge contributes to the strategic management of year-round seed availability. By elucidating the natural reproductive cycles of these economically important species, researchers can optimize breeding programs to align with environmental conditions, potentially identifying genetically different stock for line development, which can breed during winter seasons.
