Abstract
Acoustic transmitters implanted in green sturgeon (Acipenser medirostris) captured in rivers in California were detected by acoustic receivers deployed within and around Baker Bay. The receivers were deployed at eight locations in the Bay and adjacent navigation channels of the Lower Columbia River during a period of anticipated channel dredging. Three of the transmitters detected were confirmed to have been implanted into green sturgeon in previous years; two were from the Sacramento River and one was from the Klamath River. The transmitters (fish) were within detection range of the receivers for only a short period, which is consistent with findings of earlier studies that green sturgeon make rapid and extensive intra-estuary movements.
