Experimental measurement of hydrosystem-induced delayed mortality in juvenile Snake River spring Chinook salmon (Oncorhynchus tshawytscha) using a large-scale acoustic array

Out-migrating Snake River salmon smolts must pass eight major hydro dams before reaching the Pacific Ocean. Direct mortality at the dams is generally low; however, the cumulative stress caused by dam passage is hypothesized to result in delayed morta

Freshwater and early marine migration and survival of endangered Cultus Lake sockeye ( Oncorhynchus nerka ) salmon were studied using the Pacific Ocean Shelf Tracking (POST) array. Smolts were acoustically tagged in 2004–2007, and their migration w

We captured 196 adult Fraser River sockeye salmon (Oncorhynchus nerka) in the Gulf of Alaska and collected blood and tissue samples to describe their energetics and physiology at an early stage of homeward migration. Somatic energy concentrations dif

Maximum tag to body size ratios for an endangered coho salmon (O. kisutch) stock based on physiology and performance

Autor: K. Fiona Cubitt, Cedar M. Chittenden, Adrian LadouceurA. Ladouceur, Kevin G. Butterworth, David Welch, Melinda C. Jacobs, R. Scott McKinley

Publikováno v: Environmental Biology of Fishes. 84:129-140

Many coho salmon stocks (Oncorhynchus kisutch) have been in decline during the past three decades. Canada’s most endangered salmon stock, the Thompson River coho salmon, is being studied extensively as managers attempt to reverse these population d

Digestion of pelagic Ctenophora and Cnidaria by fish

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 60:825-829

The diet of chum salmon (Oncorhynchus keta) can range from a primarily arthropod to a primarily gelatinous composition. Because no data exist for the digestion rates of gelatinous prey in any fish, it has not been possible to convert data on stomach

Influence of multiple dam passage on survival of juvenile Chinook salmon in the Columbia River estuary and coastal ocean

Autor: Aswea D. Porter, Melinda C. Jacobs-Scott, Paul M. Winchell, Erin L. Rechisky, David Welch

Multiple dam passage during seaward migration is thought to reduce the subsequent survival of Snake River Chinook salmon. This hypothesis developed because juvenile Chinook salmon from the Snake River, the Columbia River’s largest tributary, migrat

Estuarine and early-marine survival of transported and in-river migrant Snake River spring Chinook salmon smolts

Autor: Erin L. Rechisky, Paul M. Winchell, John L. McKern, David Welch, Melinda C. Jacobs-Scott, Aswea D. Porter

Publikováno v: Scientific Reports

Many juvenile Snake River Chinook salmon are transported downriver to avoid hydroelectric dams in the Columbia River basin. As mortality to the final dam is ∼50%, transported fish should return as adults at roughly double the rate of nontransported
