Toward a national animal telemetry network for aquatic observations in the United States. Each quantitative PCR replicate consisted of a 5-μL reaction volume. Canadian Journal of Fisheries and Aquatic Sciences. During our snorkel survey we located an adult sturgeon and recorded its image and location using a GoPro® HERO 4 (GoPro, Inc., San Mateo, CA) video camera (Video S1, Supplemental Material) and a Trimble® GeoXT (Trimble, Inc., Sunnyvale, CA) handheld global positioning system unit.

The rapid, frequent long‐distance migrations by these fish may make them vulnerable to bycatch in bottom trawl fisheries on the shelf waters of western North America. Freshwater and marine migration and survival of endangered Cultus Lake sockeye salmon (Oncorhynchus nerka) smolts using POST, a large-scale acoustic telemetry array. Additional research is needed to better understand limitations to passage of these fish relative to river flow and depth levels. If not, we may lose thousands of years of genetic evolution and progress to extinction. In: Leet WS, Dewees CM, Haugen CW (eds) California’s living marine resources and their utilization. Upon returning we conducted a snorkel survey, captured the fish on camera, and used a gridded environmental deoxyribonucleic acid (eDNA) sampling regime to verify the species of the observed fish. 2015). Migration of green sturgeon, Acipenser medirostris, in the Sacramento River. 2016) and Green Sturgeon both have large geographic ranges (Moyle 2002; NMFS 2015; Moser et al.

The two main spawning populations in the Rogue and Klamath-Trinity rivers occupy separate basins reducing the potential for loss of the DPS through catastrophic events.

Additionally, all White Sturgeon eDNA samples were negative. We detected Green Sturgeon eDNA in two samples collected at the deep pool (site 2) where the sturgeon was visually recorded on 5 October 2017 (Table 1). Green sturgeon were first described by Ayres (1854) from San Francisco Bay.

) This confirmed observation of an adult Green Sturgeon in the Stanislaus River near Knights Ferry (rkm 86.1) is an important discovery that extends the previously accepted geographical range for the species by an additional ∼86 rkm upstream into the Stanislaus River. This pattern of detections suggests that important overwintering grounds may be north of Vancouver Island and south of Cape Spencer, Alaska. White Sturgeon (Hildebrand et al.
