This past Saturday night I was visiting a friend who has a small creek in his yard. After dinner a few of us went down to the water with our headlamps.
Using the light (incandescent) we were able to locate a whole lot of crayfish. Then we waded in, held their heads down with a twig and grabbed their tails. We caught a dozen in just a few minutes.

This made me think. Crawdads are easier to find and catch than fish. As long as wading into a creek will not cause you to get hypothermic catching crayfish could be an easy way to find food in the wilderness. They also make great bait as well.

Man I felt like a 10 year old kid all over again standing in that tiny creek hunting for "mudbugs".
