Im new to snapping turtle fishing.?

I have never set lines for snapping turtles and would love to catch some for some stew. A friend told me to buy large turtle hooks and some b boat anchor rope. The place i want to fish is a decent size river bend with a depth of about six feet. I am thinking of tying off on a decent size tree branch or trunk... my questions are really what is the best set up for me to use, what materials to use, and what techniques to use. Any comments, links or videos would be very help full thanks.
