Tim and Barbara, You are right that a hook and line is a poor way to catch crawdads. You'd always snag one or two going after pan fish like sunfish, bluegill, and MUDCATS, but never enough to make a mess. Besides, those are the big ones, and they're not so good. If you want to catch crawdads, seining is the only way to go. Back couple hundred year ago when we were kids, my brother and I had 3 or 4 farm ponds we'd hit, and in 20 or 30 minutes we'd have all we could handle. We'd sell 200 dozen or so to the bait shops up and down the river and eat the rest. Now these were the little soft shell crawdads, and they're pretty good. They peel real easy, and you just pull that mud vein out of the tail-it comes right out. Doesn't take any time to clean a mess. Only eat the tail though, that's the meat of it. It's about the same as shrimp. I never knew them to be in moving water, only in still, but They might be in creeks and rivers too.
