How much bigger is your turtle than the crab and crayfish? If they are close in size your turtle may ignore them and eventually get used to them as tank mates. I say "may" but it's not likely. Like iac637 said, once those guys molt they are very vulnerable. But then again, even their hardened shells are no match for a turtle's beak. That's another thing, crustaceans are pretty sensitive to water quality.
