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 ...

Monitoring Atlantic Salmon (Salmo salar) Smolt Migration in a Large River System Using Environmental DNA

Environmental DNA
Effective monitoring strategies are key for aquatic species conservation, but traditional methods often require significant resources, especially in large aquatic systems. The emergence of quantitative environmental DNA (eDNA) is a promising alternative.

Use of fatty acid profiles to monitor the escape history of farmed Atlantic salmon

Aquaculture Environment Interactions, 2015
Farmed Atlantic salmon can escape from fish farms at various stages of their life, from juveniles to large mature fish. Escapees that enter rivers to spawn pose a threat to the genetic integrity of wild populations.

Welfare and Physiological Consequences of Non‐Lethal Blood Sampling From the Caudal Vasculature of Atlantic Salmon (Salmo salar L.)

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT The objective of this study was to evaluate welfare and health effects following single and repeated non‐lethal blood sampling from the caudal vasculature of Atlantic salmon. Two experiments were conducted at three different temperatures: a 6‐week freshwater experiment with fish weighing 50–100 g, undergoing up to four blood withdrawals, and a

Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.

Regulation of the glucocorticoid receptor mRNA levels in the gills of Atlantic salmon (Salmo salar) during smoltification

Knowledge and Management of Aquatic Ecosystems, 1998
The regulation of the Glucocorticoid Receptor (GR) transcript was investigated in the gills of Atlantic salmon (Salmo salar) during the parr-smolt transformation.

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,

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 ...

Comparative study of blood biochemistry in clinically healthy farmed barramundi (Lates calcarifer) and rainbow trout (Oncorhynchus mykiss) from freshwater recirculating aquaculture systems

Australian Veterinary Journal, Volume 104, Issue 6, Page 385-394, June 2026.
Barramundi (Lates calcarifer) is an economically significant aquaculture species and ranks among Australia's top five farmed finfish. As global production intensifies, understanding the physiology and health of barramundi is essential to support animal welfare and industry profitability.

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 ...
