I honestly have never tried it, maybe you could do a bit of research online.
I wouldn't think they would have too much meat, or at least not as much as a crayfish.

This morning I found teeny bugs all over her enclosure, thought OMG NO! Well, on closer examination, they are pinhead crickets!!! Apparently the crickets Moggie didn't dig out yet, BRED! Great on the fiddler crabs, since my aunt lives on the intercoastal and I can grab as many as I like from her.
She enjoyed chasing them down, and that is what I am after. Not making htem a diet, but supplementing with something she can dig out and chase. Like the earthworms, which I still haven't gotten yet. Zoos call it "environmental enrichment".
