I always use my 30.06, never had one get away. Watch out for the water drops though. LOL. For photography any lens will work. Sorry, just could not pass up the "shot" at this.
A shotgun would be easiest, but if you’re looking for challenge try a BB gun. For a real challenge a slingshot.
A grenade launcher would get them all with a single shot. They couldn't escape by hugging the bottom of the barrel. I suspect that a couple of feet of water would make the shotgun and BB gun ineffective.
