Reasoning for not allowing "hunting" is they don't want the hogs to become a commodity leading to folks illegally dumping more hogs in there. But I can tell you from experience no one will say a word if you kill 1 or 5 while deer hunting. Game bags in a pack work wonders. They are intensively trapping and night hunting them to keep numbers down and I stick an arrow in every one I see if I can.
