USFWS proposes to list the Fish Lake Valley tui chub (Siphateles obesus ssp.), a fish found in Esmeralda County in southwestern Nevada, as an endangered species under the ESA. This determination also serves as their 12-month finding on a petition to list the Fish Lake Valley tui chub. After a review of the best scientific and commercial data available, USFWS find that listing the Fish Lake Valley tui chub is warranted. If adopted as proposed, this rule would extend the Act's protections to the Fish Lake Valley tui chub. USFWS will accept comments received or postmarked on or before 21 July 2025. POC is Justin Barrett, Acting Field Supervisor, USFWS, Reno Fish and Wildlife Office, 1340 Financial Blvd., Suite 234, Reno, NV 89502; tele 775-861-6338.
