I recently started Catfishing on the MN river. It runs through a lot of farm country with considerable run off. Most of the people that I talk to think that its harmful and the fish are full of chemicals. (Note: Catfishing is not a sought after fish in a state full of Walley, Bass and Pike) According to the DNR stats for the state of MN they make no mention of that (pesticides) as a safety issue. At first I was content with catch and release but after reading the recipies and posts on BOC. I was ready to take a bite out of a couple of live ones last time I was out fishing. My thoughts are that most of the runoff is basically harmless otherwise it would probably be illegal. And I would really like to eat some of my catch. Any input appreciated.
