My little trick to getting crawfish is to go fish a creek. Caatch a little bluegill and put him on a stringer. lay a landing net in the water with the handle on the bank.. then I put my little bluegil in the water centered on the net. All the crawfish will come up and start eating the bluegil. it's like a feeding frenzy!! then put up the net and get all the crawfish. and set the net back out again for another set! it works great.
