Climate change impacts on fish in the Baltic Sea

Journal of Fish Biology, EarlyView.
Abstract The Baltic Sea is a marginal sea with strong abiotic gradients harbouring fish of both marine and freshwater origin. Here we review the empirical evidence for how changes in climate variables have impacted different fish and fish communities in the Baltic Sea.

Tracking hatchery and wild Atlantic salmon (Salmo salar) smolt during river exit and early marine migration to assess survival, predation risk and migration speed

Journal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...

The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

Journal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. While K. thyrsites has previously been identified in migratory Atlantic mackerel in the northern Northeast Atlantic Ocean,

The First Report of Cod Gill Poxvirus in Gills of Atlantic Cod (Gadus morhua L.) Suffering From Cardiorespiratory Disease

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Atlantic cod farming experiences renewed growth in Norway, and increased awareness is essential to address emerging diseases in this species. There are few reports on gill diseases in cod, and to date, no viral gill infections of cod have been documented. In this study, we collected samples from three sequential time points in summer 2023 from

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

Journal of Fish Diseases, EarlyView.
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 ...

Fish Poxviruses on the Rise: Prospects for Aquatic Health

Journal of Fish Diseases, EarlyView.
ABSTRACT Fish poxviruses are increasingly recognised as emerging pathogens of fish and should be considered in cases of unexplained gill or skin pathology. Carp edema virus (CEV), the causative agent of koi sleepy disease in common carp and koi (Cyprinus carpio), represents the first known example.
