Using the Diet Composition of Adult Chinook Salmon to Understand the Regional Structure of Salish Sea Forage Communities

Fisheries Oceanography, Volume 35, Issue 4, Page 565-579, July 2026.
ABSTRACT Small pelagic fish and other forage species are patchily distributed over space and time, resulting in variable foraging conditions experienced by their predators. The high‐resolution data necessary to understand the spatiotemporal structure of forage communities are challenging to collect with expensive fishery‐independent surveys, meaning ...

First Report of the Malacosporean Parasite Tetracapsuloides bryosalmonae in the Faroe Islands Reveals Widespread Distribution and High Prevalence in Brown Trout

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT The myxozoan endoparasite Tetracapsuloides bryosalmonae (Tb), the causative agent of proliferative kidney disease (PKD) in salmonids, has predominantly been reported in temperate regions of continental Europe and North America. Here, we present the first record of Tb in the Faroe Islands, extending the known northern distribution of the ...

Egg Size Variation Between Wild and Captive Broodstock Brown Trout (Salmo trutta) in Watersheds of Three Peri‐Alpine Lakes

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
This study examined variations in the egg size of wild‐caught and captive broodstock (created from the direct offspring of wild‐caught) brown trout (Salmo trutta) from three peri‐Alpine lakes (Lake Constance, Lake Lucerne and Lake Zurich). It showed that there was lake‐specific variation in egg size between the two groups of trout.

Positive Doping Test Linked to Crumb Rubber From Artificial Football Pitch: Case Report

Drug Testing and Analysis, Volume 18, Issue 6, Page 719-724, June 2026.
1,3‐DMBA was detected in urine samples of eight athletes following a doping control, resulting in one AAF and levels below WADA's MRL in seven teammates. Investigation revealed contamination from rubber infill used on the indoor artificial turf, with analysis confirming 1,3‐DMBA in the turf's crumb rubber originating from recycled tires.

Effects of Different SNP Calling and Sequence Mapping Choices on the Inference of Genetic Architecture Underlying Migration Tendency

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We re‐analysed RAD‐Seq data from brown trout using a conspecific reference genome and alternative SNP pipelines. Population structure was robust across methods, but using the brown trout reference improved detection of biologically relevant outlier SNPs. ABSTRACT Genome‐wide association studies with identification of biologically relevant genes rely on

Effect of dietary iron (Fe) supplementation on growth performance, hematological parameters and anti-oxidant responses of coho salmon Oncorhynchus kisutch (Walbaum, 1792) post-smolts

Aquaculture Reports
Effects of graded dietary iron (Fe) levels on coho salmon Oncorhynchus kisutch (Walbaum, 1792) post-smolts were assessed by determining the growth performance, Fe deposited in tissue, liver and serum antioxidant and immunity responses.

Comparison of infectious agents detected from hatchery and wild juvenile Coho salmon in British Columbia, 2008-2018.

PLoS ONE, 2019
Infectious diseases are potential contributors to decline in Coho salmon (Oncorhynchus kisutch) populations. Although pathogens are theoretically considered to pose higher risk in high-density rearing environments like hatcheries, there is no direct ...

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

River Research and Applications, Volume 42, Issue 5, Page 1069-1082, June 2026.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Disease‐associated mortality drives reduction in Yukon River Chinook salmon escapement: A novel method for quantifying the negative impacts of ‘misfit’ parasites to improve fisheries management

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Alaska Department of Fish and Game is implementing an annual monitoring program at the mouth of the Yukon River where our model will estimate the proportion of Chinook salmon at risk from parasite‐induced mortality to inform annual management. Moreover, the model is broadly applicable to other fungal‐like and myxozoan parasites of conservation concern,

Infectious hematopoietic necrosis virus (IHNV) in fish and its consequences for fish farming: A comprehensive review

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Viral diseases are a major concern in finfish aquaculture, leading to severe health problems. Infectious hematopoietic necrosis (IHN) is a highly transmissible systemic viral disease that primarily affects salmonids, causing significant mortality and economic losses to the salmonid farming industry.
