RBC, are you sure it's really a snapper ? Snappers have well defined ridges and points on their shell...with a VERY long tail, it's generally as long as the shell. If it's truely a snapper, patiently wait him out with a .22, if it's a common turtle, let him clean up the injured or sick left-overs. The reasoning is that you don't want a Snapper to breed, they are VERY dangerous and do eat live fish. Consider an adult Snapper much like a dangerous snake, it only takes once, and you'll have a LOT of regrets.
