A lot of the fish up that far, especially the hens, will have meat similar to what you're talking about. We have made it a practice that if there is a shade of pink in the opercle (cheek), then we rub her belly, if she is loose, she goes back. The bucks will hold up far better, even when they take a more bronze color...but the hens
I see so many people bonking fish that I would bet my life saving on have mush for meat. There were some last week that looked like spawning silvers, just blood red sides with black bellies. Its a hatchery fish, and a personal choice, but I don't keep them.
The fish on the right had meat as pale as the skin on my face...some can be very decieving. The one on the left had *decent* meat...
This big girl was past my "keeper" stage also so she went back...notice how limp the body looks. The better fish we have gotten stay firm when held for pics... like the pics of Amermans big nates...very straight body.
The NF is often good for numbers of fish(and people

), but the quality isn't always there...
