How do I tell the difference between a Salmon and a Sea-Trout?

Well Sea-Trout tails are square and thick at the wrist whilst Salmon tails are concaved and slender at the wrist. Spots on a sea-Trout continue below the lateral line whilst Salmon have fewer spots below the lateral line. The eyes on a Sea-Trout are further forward in the head than the Salmon. Finally if you’re still unsure count the scales between the adipose fin and the lateral line, a count of less than twelve, it is a Salmon, more than twelve and it’s a Sea-Trout.
