they fall under "baitfish" .. you can catch them by fishing for them, netting or trapping them .. I am not sure about bow and arrow though .. I thought that was only carp .. dont have a regs book handy to find out for sure .. as for there uses you can cut them up to catch catfish (leave them out in the sun for a few days to get them good and stinky) or use the smaller ones for pike/muskie
