Aquaculture may take place in enclosed shallow coastal areas, in cages at or below the surface of the open sea, in freshwater ponds, or in large tanks. It is a commercially important method of producing seafood such as mussels, oysters, clams, lobsters, crawfish, and shrimps, and fish such as salmon, tilapia, and catfish. Seaweeds may be grown in similar situations. The method of growing plants in nutrient solution instead of soil is called hydroponics.
