Aquaculture is the practice of farming aquatic organisms, such as fish, shellfish, and aquatic plants, in controlled environments. This method can take place in freshwater or saltwater and includes various techniques like pond farming, cage farming, and recirculating systems. Aquaculture aims to produce food, restore habitats, and support local economies. This industry plays a crucial role in global food production, providing a significant source of protein for many people. It helps reduce pressure on wild fish populations and can contribute to sustainable practices when managed responsibly. Key species in aquaculture include salmon, shrimp, and tilapia.
