Challenge Mystery Fish
It's a COHO!

Coho swimming in a stream

This is a tricky one. It looks like this fish could be either a coho, a sockeye, or even a chinook. But, the identification characteristics that gives this fish away are its size, the horizontal stripe along its side, and the red splotch of color near its cheek. Notice that the back of the fish is dark, and the sides are red. If this was a sockeye, the whole body would be bright red (if it was a male) or would be dull colored (if it was a female). But this fish has a black back and brilliant sides, characteristic of a coho. It also has the characteristic splotch of color on its cheek and lacks a massive size, like a chinook. Great work if you successfully identified this salmon.
