Hey! I am just starting to fish in a lake and is more of a aquarium guy so I am going to bring some nightcrawlers but wen i go fishing i sometimes find these crayfish at the end of my line. Can I use them as bait? Live of course. I am trying to catch catfish but there r also other fish that might wind up and i am okay with it. There r small amount of rainbow trout, catfish, crappie, and bluegill.
