Decapoda (Crayfish and Freshwater Shrimp) of Michigan

Relative to neighboring states to our south, Michigan tends to be rather depauperate in crayfish diversity, with only 8 cambarid species recorded from the state. Orconectes rusticus, native to the Ohio River watershed, is not native to Michigan, its common occurence a result of being used as fish bait and released. Similarly, Procambarus clarkii, native to the southern US, has become introduced far outside its native range due to aquaculture, the aquarium trade, and its use as fish bait. One species of freshwater shrimp occurs in Michigan.
