This book was released on 2014-03 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Juvenile Chinook salmon (Oncorhynchus tshawytscha) emigrating from natal tributaries of the Sacramento River may use a number of migration routes to negotiate the Sacramento-San Joaquin River Delta (hereafter, "the Delta"), each of which may influence their probability of surviving. We applied a mark-recapture model to data from acoustically tagged juvenile late-fall Chinook salmon that migrated through the Delta during the winter of 2009-10 (hereafter, 2010). This report presents findings from our fourth year of research.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Outmigration is an important life stage for Chinook salmon (Oncorhynchus tshawytscha) survival in the Sacramento River, and yet our understanding of their behavior and needs during this time is limited. To gain a better understanding of their survival and movement rates during outmigration, late fall run Chinook salmon smolts were tracked using acoustic telemetry techniques. Habitat features were measured and quantified throughout the study area to evaluate how Chinook salmon respond to key levee features including shade, instream woody material, and aquatic vegetation. The overall average movement speed through the entire study area was 0.77 m/s with an overall survival of 86%. Based on multiple linear regressions, vegetation was found to have the largest effect on speed with fish slowing down with increased vegetation cover. Shade, river mile, and velocity also had significant effects on movement speeds, but instream woody material was not significant. The result for woody material was surprising since it was anticipated to have a large impact on movement speeds. A positive correlation was found between faster fish movement speeds and higher survival. No evidence of diel movement patterns was found after releasing the fish. These finding can help managers create sites better designed to help Chinook salmon in the Sacramento River system. Results from this paper indicate that the type of woody material being installed might not be appropriate for this life stage of salmon.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extirpation of Central Valley spring-run Chinook salmon ESU (Oncorhynchus tshawytscha) from the San Joaquin River is emblematic of salmonid declines across the Pacific Northwest. Previous telemetry studies monitoring reintroduction of threatened spring-run Chinook salmon to the San Joaquin River revealed low out-migration survival of juveniles from rehabilitated upriver habitats to the ocean. To evaluate the link between overall habitat conditions and survivorship, we combined state-of-the-art habitat mapping approaches (Fast Automated Limnological Measurements or "FLAMe") with classic acoustic telemetry technology along the 270 km emigration corridor in Spring of 2019. We used classification algorithms on FLAMe data to develop a zonation scheme for aquatic habitats along the mainstem San Joaquin River, including a portion of the Delta. Despite elevated flow conditions in 2019, outmigration survival of smolts was again comparatively low (5%). However, our habitat-based classification scheme described variation in survival of acoustic-tagged juvenile spring-run Chinook salmon better than other candidate models based on geography or distance. Two regional mortality sinks were evident along the water quality transect, revealing poor survival in areas with higher temperatures and low levels of chlorophyll-[alpha], fDOM, and turbidity. These findings illustrate an overall value in integrating simple classification frameworks to improve our understanding of habitat variation on survival dynamics of imperiled salmonid populations.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Riverine ecosystems around the world have undergone extensive anthropogenic alterations, often to the detriment of native aquatic biodiversity. Migratory fishes are particularly vulnerable to habitat fragmentation and degradation. For example, Chinook Salmon populations in the Sacramento and San Joaquin Rivers, CA have been declining for nearly a century. Its Mediterranean climate, position in a landscape dominated by urban and agricultural land use, and the presence of an inland delta that serves as the hub of California's vast water conveyance system, makes this a particularly perilous region for migrating juvenile salmon. These studies use acoustic telemetry as tool to investigate survival and routing of juvenile fall and spring-run Chinook salmon during their riverine and estuarine migratory phases in the Sacramento and San Joaquin Rivers. Survival to the ocean in these river systems is already lower relative to other Chinook Salmon populations in North American. Tracking studies included investigations of the sub-lethal effects of tagging fish with acoustic transmitters, movement ecology and survival of two distinct evolutionary significant units of Chinook Salmon during an historic drought, and the movement ecology and survival of a reintroduced population of Chinook Salmon in the San Joaquin River.
