Industrial practice of catching, processing or selling aquatic animals such as fish and shellfish is called fishery.

Shellfish is a fisheries term used to represent the aquatic invertebrates bearing an exoskeleton. These are widely used as food across the world. It includes various species of molluscs (mussels and oysters), arthropods (crabs, prawns), and echinoderms.

Fish is a cold-blooded vertebrate with gills and fins. They live in water and are widely used as food. They are broadly divided into 2 types based on their habitat: marine fishes and freshwater fishes.

Marine fishes are fishes that live in sea or ocean water. Common examples include Hilsa, mackerel, sardine and pomfret.

Freshwater fishes are those which live in freshwater, such as rivers, ponds and lakes. Common examples include common carp, rohu and catla.
