I am actually getting my catfish on the main lake and it's some of the best fish I've ever eaten but only after careful trimming. I'm not getting the big guys yet like I did on the Yellowstone River but I just started doing it here. It may seem like there's not much meat on these smaller cats after trimming but it's worth it. I used to just cut off yellow meat and fry it. Now I trim out the middle vein, yellow meat, and all meat that's discolored or has a weird texture. The remaining meat smells fresh and the pile of trimmings smells fishy. I feed the nasty to my long haired tortie cat.
I soak all my fillets in saltwater overnight in a fridge. It's crazy how much slime comes out.
