Sea foods. Most common sea foods.

Sea Foods:

Sea foods includes all those animals and plants found in sea water used as food by human being. For example fish and shellfish and seaweeds and microalgae. Shellfish include various species of molluscs, crustaceans, and echinoderms while edible sea plants, such as some seaweeds and microalgae, are widely eaten as seafood around the world, especially in Asia. Man has been using aquatic animals and plants as food since the his birth. Man had been harvesting wild sea food as a primary source of food. The harvesting of wild seafood is usually known as fishing or hunting, and the cultivation and farming of seafood is known as aquaculture, or fish farming in the case of fish. Seafood is often distinguished from meat, although it is still animal and is excluded in a strict vegetarian diet. Seafood is an important source of protein in many dietsaround the world, especially in coastal areas.

Most of the seafood harvest is consumed by humans, but a significant proportion is used as fish food to farm other fish or rear farm animals. Some seafoods (kelp) are used as food for other plants (fertilizer). In these ways, seafoods are indirectly used to produce further food for human consumption. Products, such as fish oil and spirulina tablets are also extracted from seafoods. Some seafood is feed to aquarium fish, or used to feed domestic pets, such as cats, and a small proportion is used in medicine, or is used industrially for non-food purposes (leather).
