Aquaculture systems are methods used to cultivate aquatic organisms, such as fish, shellfish, and plants, in controlled environments. These systems can be found in various forms, including ponds, cages, and recirculating aquaculture systems (RAS). They aim to produce seafood efficiently while minimizing environmental impact. These systems can be categorized into extensive, semi-intensive, and intensive systems, depending on the level of management and input. Extensive systems rely on natural food sources, while intensive systems use artificial feeds and advanced technology to maximize production. Overall, aquaculture plays a crucial role in meeting global seafood demand.
