It's to force them to discharge the waste inside them. Think about it ... and you will always do it.

From a site that sells live crawfish like people buy lobsters. 10. What does it mean to "purge" live crawfish and do we have to purge our live crawfish before we boil? NO, you do not have to purge. Purging is a process to help a live crawfish excrete any waste it may be carrying prior to boiling. Method calls for submerging live crawfish in say a small baby pool with cold water and salt. Live crawfish submerged 10-15 minutes will reportedly help live crawfish purge their waste system. They do need to be boiled soon after if you elect to purge! Many live crawfish will arrive with cleaned veins where purging is a personal preference and NOT mandatory! Crawfish veins are easier to peel away than say boiled shrimp. So we do NOT typically purge as it is NOT a guaranteed process.

Well, you eat their tails. What runs down the tails? Yep, the poop line. If it's cleaned out (from salt water, which makes them purge) then you can eat the whole thing and not worry about having to peel the "vein."
This is why you purge lobster or shrimp in fresh water... same theory.

I beg to disagree with Sam. I'd use catfish as crawfish bait, not vice versa. Crawfish, lobster, prawns and shrimp are among the best of all seafood.

Aside from cleaning them out, the salt will actually help season them

To force them to clean out their own insides. They have a lot of silt going through them which is not nice to eat.

I dont know why but I do know that I would not eat those nasty looking creatures. We do use them for catfish bait, and the catfish love them.
