Abstract: Better nutrition in aquaculture is essential for higher growth and improved yields. Enhancing production through the intensification of cultural practices ensures profitability and a sustained supply of fish protein. However, such intensification of aquaculture practices shifts the emphasis to feed-based culture. Feed cost represents the significant operational cost in animal production. In aquaculture, it represents about 50-60% of the operational costs and plays a vital role in determining the profitability of aquaculture. As fish meal resources are declining, the ingredients for these feeds will have to be sourced mainly from plants. Plant-based ingredients are widely available, renewable, and are already being used in aquafeed. These agro-industrial residues like cottonseed meal can be suitable, especially after fermentation, due to their low production cost and high nutritional value. Improved nutritional quality of agro-waste as feed is considered very important for its practical application in fish feed. The improvement in nutrient quality is best obtained by solid-state fermentation, resulting in decreased antinutritional factors of agro-waste products.
