Frank, I use a fish trap all the time. I made one from 1 inch PVC pipe (so it floats) and semi-rigid plastic netting you can buy from pond suppliers. It is about the same size as you describe. It has 4 entry points, 2 on each of opposite sides. They are simple round holes with a cone in the inside. I catch BG very easily. Can catch as big a BG as can get through the hole. Never caught a bass. I can put this out over night and some times have 30 to 50 fish by next day. Sometimes I get all small ones sometimes I get all big ones. Depends on where I put it and if the fish are moving around.
