The poor cod, Trisopterus minutus, is a temperate marine fish belonging to the cod family (Gadidae). It is red brown in color and has a pronounced chin barbel. It may grow up to a length of 40cm. It is usually found in small shoals at depths between 10 and 300 meters on muddy or sandy bottoms. Its distribution spans the eastern Atlantic; from Norwegian coasts to Portugal and along the Atlantic coast of Morocco; also in the Mediterranean. Spawning takes place towards the end of winter.
It feeds on crustaceans and small fishes. They are eaten by seals, whales and dolphins. It is commercially harvested for the production of fish meal, and in southern Europe as food.
Cod is the common name for the genus Gadus of demersal fishes, belonging to the family Gadidae. Cod is also used as part of the common name for a number of other fishes, and there are species suggested to belong to genus Gadus that are not called cod (the Alaska pollock).
The two most important species of cod are the Atlantic cod (Gadus morhua), which lives in the colder waters and deeper sea regions throughout the North Atlantic, and the Pacific cod (Gadus macrocephalus), found in both eastern and western regions of the northern Pacific. Gadus morhua was named by Linnaeus in 1758. (However, G. morhua callarias, a low salinity, non-migratory race restricted to parts of the Baltic, was originally described as Gadus callarias by Linnaeus.)
