Silver salmon are a popular type of salmon fish known for their silvery skin and rich flavor. They are also referred to as Coho salmon, which is their scientific name. Other common synonyms for silver salmon include hooknose salmon, blueback salmon, and silver Coho. These synonyms are often used interchangeably with silver salmon to describe the species. Hooknose salmon is derived from the distinctive hook shape on the males' noses during spawning. Blueback salmon, on the other hand, comes from their blue-green hue and silver scales. Overall, these synonyms are just as accurate as the term "silver salmon" to describe this sought-after fish.
