Classification of Post‐Delousing Mortality in Farmed Atlantic Salmon: A Case Study of Standardised Causal Classification at Fish‐Level

Journal of Fish Diseases, Volume 48, Issue 5, May 2025.
ABSTRACT The study investigated cause‐specific, fish‐level mortality of farmed Atlantic salmon following mechanical delousing. We visited three populations at two marine sites belonging to one company at four different time points, from 1 day before to 13 days after the mechanical delousing. A total of 453 dead fish were collected and necropsied during

Pathogen and Gene Expression Profiles of Atlantic Salmon From an Endangered Population

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT The role of pathogens in impacting the behaviour and fate of salmonids has been studied extensively for some selected pathogens such as sea lice. However, the whole pathobiome of the fish are seldom considered and may confound and influence the study species in situ.

The Pathobiome of Salmo trutta From the North Sea to the Barents Sea

Journal of Biogeography, Volume 52, Issue 3, Page 558-570, March 2025.
ABSTRACT Aim Salmonids are some of the best studied species with respect to their pathobiome, and at the northern range limit, there is potential for pathogens to expand with both climate change and increased fish farming in the north. Location We sampled sea‐run brown trout from throughout Norway for gill tissue and conducted both pooled and ...

Melanisation in Salmonid Skeletal Muscle: A Review

Journal of Fish Diseases, Volume 48, Issue 3, March 2025.
ABSTRACT Melanisation can occur in the musculature of fish. A well‐known form is the melanised focal changes, or ‘black spots’, in the fillet of farmed Atlantic salmon (Salmo salar). The aetiology of black spots has not been fully determined, though recent research has emphasised the role of fat necrosis in their development.

Factors Influencing the Prevalence of Hyperpigmented Melanistic Lesions in Smallmouth Bass Micropterus dolomieu in the Susquehanna River Basin, Pennsylvania

Journal of Fish Diseases, Volume 48, Issue 1, January 2025.
ABSTRACT Hyperpigmented melanistic lesions (HPMLs) are a visual anomaly documented on the skin of smallmouth bass Micropterus dolomieu in the Susquehanna River Basin, Pennsylvania and in numerous other geographical locations. Currently, there is a lack of information on environmental and fish characteristics that may influence the prevalence of HPMLs ...

Molecular characterization of Piscine orthoreovirus (PRV) and its pathogenesis in salmonids

, 2019
Piscine orthoreovirus (PRV) is a virus of salmonid fish. PRV has been associated with different diseases in various salmonid fish species, including heart and skeletal muscle inflammation (HSMI) in Atlantic salmon and more recently a disease resembling HSMI in rainbow trout.

Fish Sludge as Feed in Circular Bioproduction: Overview of Biological and Chemical Hazards in Fish Sludge and Their Potential Fate via Ingestion by Invertebrates

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
This review provides knowledge of the biosecurity risks of using fish sludge to produce novel feed ingredients from low‐trophic, extractive animal species in circular value chains. The review includes nutritional composition, sludge treatment practices, EU regulations, and the fate of microbial and chemical hazards contained in sludge till raw ...

PRV-1 Virulence in Atlantic Salmon Is Affected by Host Genotype

Viruses
Heart and skeletal muscle inflammation (HSMI) is a significant disease affecting Atlantic salmon (Salmo salar) production in Norway but has had limited impact to production in North America. The causative agent of HSMI is piscine orthoreovirus genotype 1
