Depends on where I'm fishing, but usually 5-10lbs. I keep the fish to eat, and I personally don't trust the amount of poisons absorbed from pesticides, fertilizers, and industrial pollution that are absorbed over the lifetime of a larger fish. It's a much bigger problem than most people realize, in fact there aren't many places left where poisons can't be detected at some level in the water. Where I live in Arkansas it's still pretty clean...with the spring fed creeks, and higher elevation rivers. The cats don't get humongous around here, anyway, but you can bet when I go fishing elsewhere I'm not interested in eating anything larger. Besides...let the big ones live to spawn...I figure a huge cat has to lay more eggs than a dink, and probably much better about protecting them, too. That's my two cents.
