USFWS proposes to list the San Francisco Bay-Delta distinct population segment (DPS) of longfin smelt (Spirinchus thaleichthys) (Bay-Delta longfin smelt), a fish species of the Pacific Coast, as an endangered species under the ESA. After a review of the best scientific and commercial information available, they find that listing the DPS is warranted. Accordingly, they propose to list the Bay-Delta longfin smelt DPS as an endangered species under the Act. If finalized this rule as proposed, it would add this DPS to the List of Endangered and Threatened Wildlife and extend the Act's protections to the DPS. They also find that the designation of critical habitat for the Bay-Delta longfin smelt is not determinable at this time. They will accept comments received or postmarked on or before 6 December 2022.
