I have eaten crayfish (we call them 'mudbugs') from cleanwater creeks. You can catch as many as you want with a curved stick and a little net. They are excellent eating when steamed or quick boiled. Since we were camping last time we caught and ate them, we had butter with us to melt and dip the tails in.

Oh man, I love crawdads! I've wondered if that bottle trap really works. If the pictures can be trusted I guess the answer is yes.

Something I've been looking for is a crawdad trap that folds flat for easy storage in my backpack. Has anyone seen anything like this or do I need to invent it myself?

Blast, that type of device works.

One modification I used as a kid was to enlarge the funnel hole by cutting below the screw top. The small diameter of the top limits the size of crawdads that can get inside. If you want the big boys you've got to open the hole.

Also, I dug a hole to bury most of the bottle, then piled rocks up around it to make it easier for them to climb inside.

One thing we discovered is that crawdads can't really swim up -- meaning that you don't really need a funnel to keep them if the trap is small and tall. If the trap is on its side the funnel is mandatory -- but if it's standing up the funnel won't be needed.

The trap works in cloudy/deep water. And it works without supervision -- a much better survival technique because it gives time to do other things. Multiple traps increases the size of supper.

Fishing also works well. But it has to be done by hand and by sight. Meaning it's time consuming. But if you don't have something to transform into a trap, fishing might be the only method that a person in a survival situation can use.

While the trap requires meat of some sort for bait, fishing for crawdads does not. Any bright tidbit of cloth tied to strip can entice a crawdad to pinch. But bait works better.

Regarding a folding trap, I guess any box will work -- a plastic one of some sort. Because the crawdads can't swim up, as long as the box is tall and skinny, it should work as a trap.

Sounds like something to add to the spring experiment list.

Promar has at least a couple sizes of traps that fold flat.

Blast:

I think you can still find the fold-flat nets around here. If I can get one, I'll see if we can stick it in the luggage in a few weeks.

But, they only work for crawfish - we don't eat crayfish round these parts. Wouldn't know what to do with the darn things.

(like, who else?)

I don't know about these crawdads and crawfish, in Eastern Australia we call them yabbies. Just as tasty though, and easy to catch.

I like the name "Yabbies", but I've never eaten them. I'm guessing they taste like shrimp or rock lobster?

Frabill, also.
