The Keta salmon (Oncorhynchus keta) is also called the Dog salmon because its canine teeth become prominent when it is time for reproduction. It lives mainly off the north-west coast of North America. But it is also fished from the Californian coast up as far as Canada, in Russia (the Bering Sea) and in Japan. This Pacific salmon is close to the Pink salmon in terms of size (less than 1 metre) and shape; but the male can be distinguished by the violet-coloured grooves on an olive-green background at the time of reproduction. The Keta lives 4 years between birth and spawning (and its death). Its growth accelerates before the period of reproduction, when it will prepare to go back up the river. The largest fish are found near the coastline. There are no farmed Keta salmon.
