Trouts and Salmons

Identifying the Sockeye Salmon

The sockeye salmon is native to the Pacific Ocean and streams of the Pacific Northwest, where it is known as the red salmon. Freshwater versions are usually bright silver on the sides, and steel-blue to green-blue on the head and back with no markings or spots. The fish found in the Great Lakes tend to be about 15 to 17 inches long and weigh around 2.5 pounds.

Look for:

-No spots on tail, but small dark speckles may be present
-Rays in anal fin ranging from 13 to 19
-Outer edge of anal fin at an angle to vertical when fin is stretched
