Cohoe is a type of salmon that is commonly found in the waters of Alaska. It is also known by several synonyms such as silver salmon, fall salmon, and blueback salmon. The silver salmon nickname is given because of the shiny silver scales that shine under the sun. The name fall salmon refers to the fact that these fish swim back to their natal streams to spawn during the fall season. Blueback salmon is another term that is used to describe this type of fish because of the blue-green tint on their backs. Regardless of the name, these delicious fish are highly sought after in the world of fishing and cuisine.
