Maine is now home to several non-native crayfish species. Of those species known to be from ‘away’, two are considered by state experts to pose the greatest threat to native ecosystems: rusty crayfish (Orconectes rusticus) and red swamp crayfish (Procambarus clarkii). Working in concert with a team of researchers, LSM is looking for volunteers to help determine the statewide distribution of these and other crayfish species and address the “Faxonious quinebaugensis Problem”.

Please visit the Maine Crayfish Project website for more information or to participate.
