Just saw a big snapper (30-50 pounds) in my new pond. Is this a problem? Do I need to get rid of him (her)? how would I do that? It is the same size as the Kentucky Turtleman catches in that crazy youtube video (I am not going to try that!).
30-50 lbs. could certainly be a problem. As was stated above, this is probably a female that will lay eggs, leading to more problems. I've never been grabbed by one, but I've sure been hissed at by some big ones, and I've had them break some pretty big sticks as we were catching them.
I love to have wildlife around my pond, but some critters are just not welcome. Large breeding size snappers are one. I've used chicken quarters and 6/0 circle hooks under a big free floating jug to catch them. When I catch them, I usually "dispatch" them with a .22 shot just behind where the neck goes into the shell.
They are excellent table fare for soups, stews, and casseroles. If you cut the head off, just keep your hands and fingers away from it for quite a while, as it can stay active and dangerous for several hours. Pond Boss had a great article within the last two years about big snappers.
The problem is not the one turtle. It is that particular turtle bringing in the whole extended family, and the generations that follow.
Good luck,
Ken
P. S. If you catch one, don't try to transport it live in the trunk of your car. As a teenager, I tried this with my dad's fairly new car. A friend and I caught a big one crossing a country road one night. We rolled it over, and tossed it in the trunk. By the time we got it home for butchering, it had peed (marinated) the car trunk into an unbelievably nasty odor that never left that car.
