There is a lot of ways to catch turtles. I used to go turtle hunting with guys that would wade river's up to their chest and run their hands up in holes in the bank and catch the turtles with their hands. This is called graveling. They would catch 40 to 50 turtles a day. I didn't have the guts to do it, so I held the bag to put them in.
In Feb. and March we would punch for them. We would take a 1/2" pipe a bout 6 foot long, put a hook on one end. We would go to a Spring or wet place from the river and run the pipe down in the mud and you could tell if you hit one by the sound, then you would run the hook down and pull the turtle out of the mud. I have also set hooks baited with groundhog meat. It was tuff and stayed on longer. We only kept the hard shell turtles because the soft shell didn't have much meat in them. Turtle meat is really good if fixed the right way. Carl L.
