USFWS announce a 12-month finding on a petition to list the spinytail crayfish (Procambarus fitzpatricki) as an endangered or threatened species under the ESA. The spinytail crayfish is a small, burrowing freshwater crayfish endemic to southern Mississippi. After a thorough review of the best available scientific and commercial information, they find that listing the spinytail crayfish as an endangered or threatened species is not warranted at this time. However, they ask the public to submit to us at any time any new information relevant to the status of the spinytail crayfish or its habitat.. The finding in this document was made on March 11, 2025. POC is James Austin, Field Supervisor, Mississippi Ecological Services Field Office, 601-540-2576, james_austin@fws.gov. (Federal Register 11 March 2025 [Proposed Rule] Pages 11696-11698)
