资源简介：

The upper Sacramento River in California contains spawning and rearing habitat for the Southern Distinct Population Segment (DPS) of North American Green Sturgeon Acipenser medirostris. In 2006, National Marine Fisheries Service published notification of the listing of the Southern DPS of North American Green Sturgeon as Threatened (71 FR 17757). The U.S. Fish and Wildlife Service’s Mainstem Juvenile Monitoring Program in Red Bluff, California has been investigating the outmigration of juvenile green sturgeon from the upper Sacramento River to the Sacramento- San Joaquin Delta. In 2016, 19 individual juvenile green sturgeon were tagged with two types of Juvenile Salmon Acoustic Telemetry System (JSATS) micro-acoustic tags. Their outmigration towards the Delta was monitored by the use of the JSATS receiver array maintained through a collaborative effort by U.S. Fish and Wildlife Service, U.S. Army Corps of Engineers and the National Oceanic and Atmospheric Administration.<div style='font-family: "Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size: 16px;'>This Web Map depicts sturgeon movement observed during a flow event produced by a rain storm on October 31st, 2016.</div>
