Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Passage Route Survival and Behavior of Juvenile Salmon at Priest Rapids Dam, Columbia River, WA [PDF]

open access: yes, 2015
Columbia River hydropower is an economic mainstay of the Pacific Northwest. However, it is well known that the construction of hydropower dams has added anthropogenic pressure to Columbia River salmon populations.

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

open access: yesJournal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

Spatial and temporal patterns of covariation in productivity of Chinook salmon populations of the northeastern Pacific Ocean

open access: yesCanadian Journal of Fisheries and Aquatic Sciences, 2018
We expand on previous analyses of environmental factors related to productivity of Chinook salmon (Oncorhynchus tshawytscha) populations by analysing data on adult recruits per spawner from 24 wild (not hatchery) Chinook salmon stocks from Oregon through

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Food base of nekton in deep-sea areas of the western Bering Sea: dynamics, current state and its consumption by pacific salmon

open access: yesИзвестия ТИНРО
Long-term dynamics of the food base for nekton in the deep-sea waters of the western Bering Sea are analyzed on the data of ecosystem surveys in 1986–2022.

Demographic changes in Chinook salmon across the Northeast Pacific Ocean

open access: yes, 2018
The demographic structure of populations is affected by life history strategies and how these interact with natural and anthropogenic factors such as exploitation, climate change, and biotic interactions. Previous work suggests that the mean size and age
