I'd take that to be hunting game species and might challenge "any" in court if given a citation.
Bottom line is it's not illegal to use lead shot on public waterways unless hunting migratory birds or on a national wildlife refuge, it's not illegal to discharge a firearm on a waterway and unless you're hunting - the regulation cited pertains to hunting, which is specifically stated in the header - it's not illegal to shoot a snake or animal from a moving vessel (except maybe in certain situations).
Crossman pellet rifles are OK, Dixie!
