Regardless the adipose gives it away and its visible for your viewing pleasure. Wh don't you just compare it to a picture of one of the 50+ fish you caught? Its anglers like this that drive me nuts talk a big game about their catch but can't even properly ID it. I can only imagine what a trout or lmb looks like to you. That's where I'm leaving this at.You can't base it on the anal fin if the anal fin isn't visible.
All the channels we catch are a dark grey.
