Aquaculture is the farming of fish and shellfish. It is the process of breeding, rearing, and harvesting of plant and animal life for human consumption from all types of aquatic environments.
Aquaculture facilities house fish and shellfish which are grown to food market size in ponds, tanks, or simulated streams. There are also open water aquaculture systems. These open water systems house fish or shellfish in enclosures that keep them safe from predators while allowing water to flow freely. This is especially popular with mussel farmers. Aquaculture makes stock restoration possible. Stock restoration is the process of raising fish and shellfish in hatcheries to release into the wild to rebuild native populations or coastal habitats. Aquaculture also includes the production of fish for the aquarium trade, and live plants for use in a wide range of food, and pharmaceutical products.
