they are worried about people dumping the leftovers in the pond. And many bait shops do not sort there fish well if at all so you can end up with some Greensunfish, bullheads, and other unwanted fish.
Excellent reply. A lot of fisherman purchase "minnow" traps and set them in small streams or lake edges. That becomes their bait for the day. As our friend above said, it can become a disaster in a pond if they are dumped. Most larger bait dealers buy their bait fish from reputable fish farms where the chance of cross contamination is far less.
