Hi,

Thanks for the welcome.

Australian freshwater crayfish are great but they have proven to be a problem in some US waterways where they have displaced local crayfish species.......in much the same way that the American Red Signal crayfish is proving to be a nuisance in UK waterways.

It's probably best to stick to local species where practicable.

Having said that, it's legal to keep Redclaw (native to Queensland) in several US states. Check with your local fisheries agency for more information.
