Changes in the long-term distribution of commercially caught Cowichan chinook

, 2015
The Cowichan River, British Columbia (BC), Canada stock of Chinook Salmon (Oncorhynchus tshawytscha) is used federally in Canada, as an escapement indicator of the Lower Georgia Strait (BC) Chinook and as such is important both locally and ...

Predicted Stream Temperatures Suggest Challenges for Pacific Salmon in Coming Decades

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT Stream temperature is a key performance driver for aquatic species and a direct metric of climate impacts. We adapted a stream temperature model to predict daily temperatures across the Pacific Northwest USA through 2100. Our results suggested that stream temperatures may rise by ~1°C by the 2050's and 2°C by the 2080's, with seasonal and ...

Management strategy evaluation for salmon habitat restoration and hatchery supplementation

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
Building on three previously published studies, this paper applies population modeling work to evaluate the effects of different habitat and hatchery management strategies on achieving recovery goals for endangered Chinook salmon. We find that it would require a >150% improvement in juvenile survival to achieve recovery goals for population abundance ...

Initial responses of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) to removal of two dams on the Elwha River, Washington State, U.S.A.

Frontiers in Ecology and Evolution
Large dam removal is being used to restore river systems, but questions remain regarding their outcomes. We examine how the removal of two large dams in the Elwha River, coupled with hatchery production and fishing closures, affected population ...

Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, Volume 33, Issue 3, Page 463-478, June 2026.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Ecological implications of changing hatchery practices for Chinook salmon in the Salish Sea

Ecosphere, 2019
For over a century, hatchery programs have been used to subsidize natural salmon populations in order to increase fisheries opportunities and, more recently, to conserve declining natural populations.

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

Fisheries Management and Ecology, Volume 33, Issue 3, Page 612-629, June 2026.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Past Pollution Can Shape Future Climatic Vulnerability: Fungicide Exposure Alters Detritivore Performance During Heatwaves and Recovery

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT Natural populations are increasingly exposed to multiple stressors, such as chemical pollution and climate‐change‐driven heatwaves. While it has become clear that we need to account for stressor interactions, it is less well understood how sequential exposure to different stressors influences organismal responses as well as their potential for
