when I catch a fish that I'm going to keep it goes in the box with its throat cut to bleed out. so I'm not going to do any culling myself. I fish the central basin and keep larger fish to go towards my limit but would much prefer the smaller eaters. but on the central basin there are a lot of days you just don't catch that many smaller fish. I personally don't believe in culling fish. I believe once you keep a fish be it bass or walleye it should be counted as part of your daily limit. but that's just for me. if the law allows others to practice culling then I'm not one to say its wrong. I do practice some catch and release on the central basin and I believe fish caught from the deep water on the central basin has a high mortality rate. but its not as high as keeping everything I catch. so each person must decide for themselves what is ethical for them.
