What we do is use a small boat the man in the back paddles up to the frog ,on cool evnings there in the water, warm evenings there on the bank ,I hang over the front of the boat and when I'm close I grab them .They stay alive and fresh.It take practice but you get to good at it ,I have cleaned out miles of rivers this way,so leave a few breeders.If the boat or paddler hit anything they are gone for a hour or so.I love the stalk. good luck and let us know how you do.Are frogs are always full of crawfish.
