Survival of migrating salmon smolts in large rivers with and without dams.
Autor: David W Welch, Erin L Rechisky, Michael C Melnychuk, Aswea D Porter, Carl J Walters, Shaun Clements, Benjamin J Clemens, R Scott McKinley, Carl Schreck
Publikováno v: PLoS Biology, Vol 6, Iss 10, p e265 (2008)
The mortality of salmon smolts during their migration out of freshwater and into the ocean has been difficult to measure. In the Columbia River, which has an extensive network of hydroelectric dams, the decline in abundance of adult salmon returning

Performance of a high-frequency (180 kHz) acoustic array for tracking juvenile Pacific salmon in the coastal ocean
Autor: Erin L. Rechisky, Aswea D. Porter, Paul M. Winchell, David W. Welch
Publikováno v: Animal Biotelemetry, Vol 8, Iss 1, Pp 1-13 (2020)
Abstract Background Acoustic telemetry is now a key research tool used to quantify juvenile salmon survival, but transmitter size has limited past studies to larger smolts (> 130 mm fork length). New, smaller, higher-frequency transmitters (“tags

Use of time-depth recorders to determine fishing depth of commercial setnets and inform management in Cook Inlet, Alaska
Autor: David W. Welch, Aswea D. Porter, Paul Winchell
Publikováno v: Animal Biotelemetry, Vol 5, Iss 1, Pp 1-9 (2017)
Abstract Background Access to harvestable surpluses of sockeye salmon is often limited by incidental harvest of Chinook salmon in the mixed-species gillnet fishery of Cook Inlet, Alaska, particularly in years of low Chinook abundance. This is restric

In situ experimental evaluation of tag burden and gill biopsy reveals survival impacts on migrating juvenile sockeye salmon
Autor: Aswea D. Porter, Christine F. Stevenson, Scott G. Hinch, Erin L. Rechisky, Nathan B. Furey, Andrew G. Lotto, Stephen J. Healy, Arthur L. Bass, Adam M. Kanigan, David Welch
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 77:1865-1869
Although telemetry is commonly used to study fishes, researchers rarely design experiments that facilitate in situ quantification of tagging-related impacts to survival. We experimentally applied high (mean burden = 9.6%) and low (2.6%) acoustic tag

Infectious agents and gene expression differ between sockeye salmon (Oncorhynchus nerka) smolt age classes but do not predict migration survival
Autor: David Welch, Kristina M. Miller, Arthur L. Bass, Erin L. Rechisky, Shaorong Li, Aswea D. Porter, Christine F. Stevenson, Nathan B. Furey, Scott G. Hinch
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 77:484-495
In some salmonid populations, multiple smolt age classes co-emigrate owing to variation in the duration of freshwater residence. While it is assumed that smolts prolong freshwater residence to maximize survival, infectious agent profiles and host gen

Quantifying survival of age-2 Chilko Lake sockeye salmon during the first 50 days of migration
Autor: Erin L. Rechisky, Nathan B. Furey, Timothy Clark, Scott G. Hinch, Aswea D. Porter, David Welch, Marika Kirstin Gale
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 76:136-152
We used acoustic telemetry to investigate survival of age-2 sockeye salmon (Oncorhynchus nerka) as they emigrated from Chilko Lake, British Columbia, Canada, to northeastern Vancouver Island (NEVI) from 2010 to 2014. We built on our previously report
