The hardest part to this snare is the trigger, but with a bit of simple carving it's easily done.
Your bait is as varied as your imagination, dig a worm, flip over a rock, catch a grasshopper, anything that fish eat will work.
It's best not to be in a survival situation, but if it happens "be prepared" burn this image into your mind... It may save your life
