PROJECTS

The Southern distinct population segment (sDPS) of green sturgeon Acipenser medirostris is federally listed as a threatened species under the United States (U.S.) Endangered Species Act (ESA). Large aggregations of both the Northern distinct population segment (nDPS) and sDPS of green sturgeon can be found congregating in Washington’s coastal estuaries mid-summer. This provides a unique opportunity to capture and study this elusive species. Existing telemetric data indicates that these fish make long migrations along the Pacific Coast with a possible year-round presence in near-shore marine waters along Washington and Oregon’s coastline. The U.S. Navy is interested in the occurrence of the threatened sDPS of green sturgeon in the Northwest Training and Testing (NWTT) study area (offshore of Washington, Oregon, and northern California).

Large aggregations of both the Northern distinct population segment (DPS) and ESA-listed Southern DPS of the green sturgeon Acipenser medirostris can be found congregating in Washington’s coastal estuaries mid-summer. This provides a unique opportunity to capture and study this elusive species. Existing telemetric data indicates that these fish make long migrations along the Pacific Coast with a possible year-round presence in near-shore marine waters along Washington and Oregon’s coastline. The U.S. Navy is interested in evaluating the impacts of military training and testing operations to protected species and, for the purpose of this project, is specifically interested in assessing impacts to the threatened Southern DPS of green sturgeon.
