Possible Effects of the Sitka Eddy on Sockeye (Oncorhynchus nerka) and Pink Salmon (Oncorhynchus gorbuscha) Migration off Southeast Alaska

open access: yes, 1986
The interannual variability of sockeye (Oncorhynchus nerka) and pink salmon (Oncorhynchus gorbuscha) catches during 1952–62 from southeast Alaska and northern British Columbia is examined in relation to the appearance and disappearance of the Sitka eddy

Genetic and phenotypic diversity in sockeye salmon, Oncorhynchus nerka

open access: yes, 2013
The research described here is the collective efforts of my MS work in two labs at the Univeristy of Washington, the Seeb Lab and the Roberts Lab, on two different projects. The first chapter was motivated by a need for improved genetic tools for the management of sockeye salmon specifically those populations inhabiting Bristol Bay.

Genotyping-in-Thousands by sequencing panel development and application for informing multi-scaled kokanee salmon (Oncorhynchus nerka) fisheries management

open access: yes, 2021
The ability to differentiate life history variants is vital for estimating fisheries management parameters, yet traditional survey methods can be inaccurate in mixed-stock fisheries.

Возрастной состав чукотской нерки Oncorhynchus nerka

open access: yesИзвестия ТИНРО (Тихоокеанского научно-исследовательского рыбохозяйственного центра), 2014
Long-term data on age composition for Chukchi populations of sockeye salmon are presented. Spawners of 23 ages are recognized in the period 1970-2013 for 10 populations: 2+, 3+, 0.1+, 0.2+, 0.3+, 0.4+, 0.5+, 1.1+, 1.2+, 1.3+, 1.4+, 1.5+, 2.1+, 2.2+, 2.3+, 2.4+, 2.5+, 3.1+, 3.2+, 3.3+, 3.4+, 4.2+, and 4.3+. The brood stock basis is formed by fiveand six-

Vertical eDNA distribution of cold‐water fishes in response to environmental variables in stratified lake

open access: yesEcology and Evolution
In summer, the survival zones of cold‐water species are predicted to narrow by both increasing water temperatures from the surface and by expanding hypoxic zones from the lake bottom.

Quantifying cutthroat trout (Oncorhynchus clarki) predation on sockeye salmon (Oncorhynchus nerka) fry using a bioenergetics approach

open access: yes, 1998
Although some sockeye salmon (Oncorhynchus nerka) enhancement programs achieve production goals in Alaskan lakes, others like the Margaret Lake project fall well below expected levels. We used bioenergetics model simulations, coupled with field sampling

Tracking Pacific salmon migrations with a prototype eDNA autosampler

open access: yesFrontiers in Ecology and Evolution
Pacific salmon (Oncorhynchus spp.) are keystone species that support commercial and recreational fisheries and play a significant role in Indigenous cultures.

X-Ray Spectrometric and Multivariate Analysis of Sockeye Salmon (Oncorhynchus nerka) from Different Geographic Regions

open access: yes, 1971
The chemical composition of samples of fry and adult sockeye salmon (Oncorhynchus nerka) collected in different areas was characterized by X-ray fluorescence spectrometry.

Blood pH and Mortality in Rainbow Trout (Salmo gairdnerii) and Sockeye Salmon (Oncorhynchus nerka)

open access: yes, 1962
Rainbow trout (Salmo gairdnerii) under light anaesthesia with MS 222 (tricaine methanesulphonate) died when their blood pH was lowered into the range of 6.8 to 6.9 by injection of either lactic acid or hydrochloric acid.

Travel specific resource selection by female Kodiak brown bears during the sockeye salmon spawning season

open access: yesMovement Ecology
Background Access to salmon resources is vital to coastal brown bear (Ursus arctos) populations. Deciphering patterns of travel allowing coastal brown bears to exploit salmon resources dispersed across the landscape is critical to understanding their ...
