I've been fishing for SRC in the Sound for several years. However, I've never been good at identifying fish species, especially the different kinds of salmon. I've always associated the very spotted ones with yellowish fin tips as SRC. Every once in a while, I hook into a fish that's a little extra silvery, or has fewer spots, but never quite sure. Since they all go back into the water, I've never worried about it too much. But now I'm curious, and after reading some stuff online, I'm not any more confident about my abilities. Any tips? First pic is an SRC with the typical look. The second I'm not so sure.
