Phenotypic Florfenicol Resistance in floR‐Harbouring Flavobacterium psychrophilum Isolates (CC‐ST90): A Case Study From Danish Freshwater Rainbow Trout Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Monitoring antimicrobial resistance (AMR) in fish pathogens is essential for supporting sustainable aquaculture. In this study, susceptibility testing and genome sequencing were used to characterize the AMR profile of seven Flavobacterium psychrophilum originating from Danish rainbow trout farms (2019–2022).

Piscirickettsiosis in Farmed Turbot, Scophthalmus maximus

Journal of Fish Diseases, Volume 49, Issue 9, September 2026.
ABSTRACT Piscirickettsia salmonis is a well‐established intracellular pathogen of farmed Atlantic salmon around the world. The bacterium has also been detected from a number of other hosts including lumpfish (Cyclopterus lumpus), seabass (Dicentrarchus labrax) and rainbow trout (Oncorhynchus mykiss).

Re‐evaluating Coho salmon (Oncorhynchus kisutch) conservation units in Canada using genomic data

Evolutionary Applications, 2022
Conservation units (CUs) are important tools for supporting the implementation of standardized management practices for exploited species. Following the adoption of the Wild Salmon Policy in Canada, CUs were defined for Pacific salmon based on ...

Dietary Tea Polyphenols Improve Growth Performance, Physiological Health and Economic Efficiency in Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Tea polyphenols (TPs) are natural bioactive compounds extensively used in aquaculture diets as a functional supplement because of their antioxidant, antimicrobial and immunomodulatory potential. Four isonitrogenous diets (crude protein: 30%) were designed with incorporating TPs at levels of 0% (control, TPs‐0), 0.025% (TPs‐1), 0.05% (TPs‐2 ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, Volume 33, Issue 4, Page 633-645, August 2026.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Dietary Pyridoxine Requirements of Coho Salmon (Oncorhynchus kisutch) Post-Smolts

Aquaculture Nutrition
A 10-week feeding trial was conducted to investigate the dietary pyridoxine requirements of coho salmon (Oncorhynchus kisutch) post-smolts with an initial mean body weight of 180.22 ± 0.41 g. Seven diets were prepared with gradient pyridoxine levels of 0.

Economic effects of disease outbreaks on U.S. salmonid farms

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The U.S. salmonid industry is the second‐largest finfish sector of U.S. aquaculture, contributing $886 million and more than 2000 jobs to the U.S. economy in 2022. The goal of this study was to develop an economic analysis of the impact of losses from disease outbreaks to the U.S. salmonid industry.

Putatively Adaptive and Genome‐Wide Genetic Variation Often Rank Populations as Similarly Distinctive

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT Identifying which populations within species to prioritize to maintain genetic diversity is challenging. Due to its direct connection to current patterns of adaptation and presumed connection to adaptive capacity, some researchers advocate prioritizing adaptive variation.

Methemoglobin determination by multi-component analysis in coho salmon (Oncorhynchus kisutch) possessing unstable hemoglobin

MethodsX, 2020
Hemoglobin derivatives are often quantified in blood to establish cardio-respiratory status and possible causes of impaired oxygen transport. The derivative known as methemoglobin results from oxidation of hemoglobin and is pathologically relevant ...

Isolation of a Rickettsiales-like organism from diseased coho salmon (Oncorhynchus kisutch ) in Chile.

, 1990
A rickettsiales-like organism was isolated in cell culture from coho salmon (Oncorhynchus kisutch) reared in seawater net pens in the vicinity of Puerto Montt, Chile S. A. and experiencing an epizootic with accompanying mortality.
