OCEAN TYPE

ocean type: translation

chinook salmon (Oncorhynchus tshawytscha) populations primarily migrating to the ocean as sub-yearlings, although yearling migrants do occur in some populations. Once in the ocean, they tend to migrate along the coastlines rather than move directly offshore. They have fewer vertebrae (<70) than stream-type chinook salmon (>70). Also called ocean-type fish
