Sea louse infection of juvenile sockeye salmon in relation to marine salmon farms on Canada's west coast. [PDF]

open access: yesPLoS ONE, 2011
BackgroundPathogens are growing threats to wildlife. The rapid growth of marine salmon farms over the past two decades has increased host abundance for pathogenic sea lice in coastal waters, and wild juvenile salmon swimming past farms are frequently ...

Age composition of Chukchi sockeye salmon Oncorhynchus nerka [PDF]

open access: yesИзвестия ТИНРО, 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+,

Spatial and ecological structure of the sockeye salmon population Oncorhynchus nerka of Kuril Lake [PDF]

open access: yesE3S Web of Conferences
This study examines the genetic structure of sockeye salmon populations in Kuril lake basin, focusing on the allelic frequencies of SNP loci that potentially carry an adaptive load. Our results reveal the division of sockeye salmon populations into three

Evaluating relationships between wild Skeena river sockeye salmon productivity and the abundance of spawning channel enhanced sockeye smolts. [PDF]

open access: yesPLoS ONE, 2014
The enhancement of salmon populations has long been used to increase the abundance of salmon returning to spawn and/or to be captured in fisheries. However, in some instances enhancement can have adverse impacts on adjacent non-enhanced populations.

Consequences of a sockeye salmon shortage for the brown bear in the basin of Lake Kurilskoe, Southern Kamchatka

open access: yesNature Conservation Research: Заповедная наука, 2021
We studied the behavioural ecology of Ursus arctos (hereinafter – brown bear or bear) in the basin of Lake Kurilskoe (Kamchatka Peninsula) in the summer and autumn of 2017–2018. The aim of this study was a comparative assessment of the behaviour of brown

Meta-Analysis of Salmon Trophic Ecology Reveals Spatial and Interspecies Dynamics Across the North Pacific Ocean

open access: yesFrontiers in Marine Science, 2021
We examined spatial patterns in diet, trophic niche width and niche overlap for chum, pink and sockeye salmon across the North Pacific during 1959–1969. This is a baseline period before major hatchery enhancement occurred coinciding with a negative phase

ON BIOLOGY OF SOCKEYE SALMON ONCORHYNCHGUS NERKA FROM THE ZHUPANOVA RIVER (EAST KAMCHATKA)

open access: yesИзвестия ТИНРО, 2018
Runs and escapements of sockeye salmon to the Zhupanova River have increased since 1985 with the run of 10.63 . 103 ind. instead of 1.45 . 103 ind. in 1960–1984, on average.
