Damnit!
This has me perplexed. The angle in which the fish is being held makes it hard to say definitively that it is any one species
Forked tail......coho or chinook. That just doesn't have the spots or "square-ness of a steelhead's tail
Lack of heavy chinook spots on tail......coho
Tidewater fresh......early springer or winter steelhead
VERY white gumline......coho or steelhead(Todd, I'm surprised that gumline doesn't sway you against it being a chinook)
Lean, slender body.....Could be a hen of any of the 3 species.
Time of year......EARLY springer or winter steel. I've never seen a platinum coho this late in the year. Bright ones? yes. Platinum ones? no.
Bunghole not protruding......Very unripe winter steel or early springer
There's too much wrong with the fins for it to be a steelhead, I've decided. Any coho hen this late is going to be riper than ripe....too bright and no protruding bunghole so I have to rule out coho. (except for that white gumline; I can't get past that)
So, I'll grudgeingly say early springer on the assumption that the fish is just so damn early and fresh that the darker gumline and spots haven't become apparent in the river environment yet.
I still don't feel like I've solved a thing.
