Major Indian carps including catla and rohu are the most important freshwater aquaculture fish in South Asia, with welfare considerations largely unexplored in this massive sector.
Indian major carp welfare represents one of the largest gaps between production scale and welfare oversight in global aquaculture. These species collectively represent hundreds of millions of individual fish, yet welfare standards, research, and monitoring are essentially absent in South Asian aquaculture. Traditional extensive pond polyculture may actually provide relatively benign welfare conditions through lower stocking density and natural food availability, but intensive monoculture with high stocking densities creates crowding stress and disease susceptibility. Harvest methods including seine netting and traditional killing practices have received minimal welfare scrutiny. Developing basic welfare standards for this sector, even at a very basic level, would have enormous aggregate welfare impact given the scale of production.
