Good to know. I’ve wondered if they are edible. I have an RV on a canal in Sargent, Texas and these things showed up five or six years ago and started digging burrows behind my bulkhead. I set a game cam out and it took me a while, but I finally caught one of them on film. They would dig from my yard all the way down to below the waterline, or vice versa.
You could go to home depot get some chicken wire and bailing wire make a simple barrel trap and bait it with castaway chicken scraps the more off smelling the better set it up right by their burrow holes and boom crab dinner. They tend to be sizable suckers too.
