There ONE BIG THING TO DO that makes them a breeze with a sharp knife. I CAUGHT, CLEANED dozzens and had 2 cousins that sold turtle meat to restrants for 8 or 10 years. tHEY CAUGHT 100'S OF POUNDS A YEAR.
It's simple heat up a pot to a boil. Big enough to dip the turle in. PUT HIM IN , LEAVE HIM LONG ENOUGH THAT THE OUTER SKIN ,MUD, SKUM COMES OFF WITH A PINCH. Flib him up on his shell (back)This SKULLING makes the seam around his upper shell and the bottom shells solf. fIRST Take a sharp knife cut around the seams that bonds the leg skin to the bottom shell first. Next cut the seam that holds the upper to the bottem shell together.
Next I shin off the heavey leg skin. 7 Different kinds of meat in a turtle.
My favoret way ti fix them is BQ (SWEAT BABY RAYS) THEM IN A COOKING BAG ON 2OO% FOR A FEW HOURS (TO THEY FALLOFF THE BONE).
I fish a lot of bass ponds and as soon as I see one I set some milk jugs.
