Description

The chum salmon is a large Pacific salmon of the family Salmonidae reaching about 1 metre. At sea it is streamlined and silvery, but spawning fish develop green flanks with purple-red, calico-like vertical bars; males grow a hooked lower jaw and large teeth. The species is anadromous: it grows up in the northern Pacific, where it eats zooplankton, small fish and squid, and migrates to spawn in the rivers of Northeast Asia and Northwest America. Like other Pacific salmon it spawns once and then dies. With its tasty flesh and roe (salmon caviar) it is one of the most important commercial salmon species in the world.
