Can anybody tell me anything about these? Ran 6 crankbaits into one on KY lake this weekend, and discovered a 80 yard long net by 10' deep hanging off 6-7 jugs. The net was made up of a high lb fishing line that had approximately 4" x 4" holes in it. I thought the jugs were normal catfish just or I would have avoided it all together. The jugs were labeled and had a name and phone number. It looked like there was 3 or 4 sets of these. Does anybody know what these are for or if they are even legal?
