Aquaculture has emerged as a vital solution to meet the growing global demand for fish amid declining wild stocks and increasing population pressure. Technological innovations in aquaculture have significantly boosted productivity, efficiency, and sustainability. This paper reviews recent advances in aquaculture techniques aimed at enhancing fish production, including recirculating aquaculture systems (RAS), biofloc technology, integrated multi-trophic aquaculture (IMTA), selective breeding, and digital monitoring. These methods collectively address challenges such as disease control, environmental degradation, and resource efficiency. The study emphasizes the importance of adopting sustainable practices to ensure long-term growth in the aquaculture industry.
