Mariculture is a specialized branch of aquaculture involving the cultivation of marine organisms for food and other products in the open ocean, an enclosed section of the ocean, or in tanks, ponds or raceways which are filled with seawater. An example of the latter is the farming of marine fish, including finfish and shellfish e.g.prawns, or oysters and seaweed in saltwater ponds. Non-food products produced by mariculture include: fish meal, nutrient agar, jewellery (e.g. cultured pearls), and cosmetics.

Algae

Seawater algae such as kelp can be farmed in at least two ways. It can be grown around a rope that is anchored to the sea floor so that they do not drift away. Off the coast of California, boats with mowers harvest the top few feet of natural kelp beds. Kelp provides alginin, an edible material used in ice cream and cosmetics. The industry also supplies the dietary supplement industry.
