The Rainbow trout (Oncorhynchus mykiss) is a fish that lives in both fresh and salt water of the family Salmonidae that grows up to 122 cm.
Description
The rainbow trout is a streamlined salmonid of the family Salmonidae that can reach about 120 cm but usually stays much smaller. It is characterised by the adipose fin between dorsal and tail fin and a broad pink to rainbow-coloured band along the silvery, dark-speckled flank. The species is native to the cool waters of western North America but has been introduced worldwide for sport fishing and aquaculture and now also occurs in many European rivers and lakes. It hunts insects, crustaceans and small fish and spawns in cool, flowing water. Some populations migrate to sea as 'steelhead'. Because of its tasty flesh it is a highly valued food and sport fish.
