Species‐ and origin‐specific susceptibility to bird predation among juvenile salmonids

Ecosphere, 2023
Juvenile salmonids often experience high mortality rates during migration and bird predation is a common source of mortality. Research suggests that hatchery‐reared salmonids are more prone to predation than wild salmonids, and that Atlantic salmon ...

Skin Microbiota of Salmonids: A Procedure to Examine Active Bacterial Populations Using an RNA-Based Approach

Applied Microbiology, 2023
Fish microbiota studies have mostly addressed intestinal bacterial communities because of their role in fish physiology; however, the skin microbiota has been studied less despite its role as the first pathogen barrier in the host.

Transcriptomic signatures differentiating carrier and dead-end fish hosts of proliferative kidney disease [PDF]

Frontiers in Cellular and Infection Microbiology
IntroductionTetracapsuloides bryosalmonae is the causative agent of proliferative kidney disease (PKD) in salmonids. Brown trout function as a carrier host, while rainbow trout serve as a dead-end host.

DRIFteRS: A dataset of drift invertebrate densities in streams and rivers across western North America, 1997-2024. [PDF]

Ecology
Abstract Prey availability is among the most influential and highly variable determinants of fish growth and freshwater habitat carrying capacity, yet it remains understudied compared to physical habitat variables (Ouellet et al., 2025; Rosenfeld et al., 2014; Weber et al., 2017).

A Review of Nonsteroidal Anti-Inflammatory Drugs for Food-Producing Animals With a Focus on Potential Applications for Farmed Finfish. [PDF]

J Fish Dis
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...

MHC class I evolution; from Northern pike to salmonids

BMC Ecology and Evolution, 2021
Background Salmonids are of major importance both as farmed and wild animals. With the changing environment comes changes in pathogenic pressures so understanding the immune system of all salmonid species is of essence.

Alternative life‐history strategy contributions to effective population size in a naturally spawning salmon population

Evolutionary Applications, 2023
Alternative life‐history tactics are predicted to affect within‐population genetic processes but have received little attention. For example, the impact of precocious males on effective population size (Ne) has not been quantified directly in Pacific ...

Why vaccines fail against Piscirickettsiosis in farmed salmon and trout and how to avoid it: A review

Frontiers in Immunology, 2022
Piscirickettsiosis is the most severe, persistent, and damaging disease that has affected the Chilean salmon industry since its origins in the 1980s. As a preventive strategy for this disease, different vaccines have been developed and used over the last
