i wouldnt release into the wild again, problems could occur.
personally i wouldnt have cought the mother in the first place, i like to leave the wild alone, and bought a captve bred crayfish instead, saying that, the shrimplets are cute and look ace, and the mother must be happy to have them all.
try selling to a lfs if they will take them, or give them to friends,
just promise me you wont sell to a restaraunt,
