Temperature effects from hydropeaking impair egg and larval development in Danube salmon Hucho hucho and brown trout Salmo trutta

Journal of Fish Biology, EarlyView.
Abstract Hydropeaking is considered an important stressor for salmonids and other species in rivers affected by hydropower. In this study, we investigated the in situ effects of hydropeaking on the survival of eggs and larvae of fall spawning brown trout as well as spring spawning Danube salmon.

Triacylglycerol-, wax ester- and sterol ester-hydrolases in midgut of Atlantic salmon (Salmo salar)

, 2008
Bile salt-dependent lipase (BSDL) is assumed to be the predominant lipid hydrolase in fish digestive tracts where it hydrolyses dietary triacylglycerols (TAG), sterol esters (SE) and wax esters (WE).

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

First Strike: Description of the Events at the First Salmon Farm Affected by the 2025 Algal Bloom in Northern Norway

Journal of Fish Diseases, EarlyView.
ABSTRACT Harmful algal blooms (HABs) are a threat to fish welfare, occurring suddenly and unexpectedly causing significant consequences for fish and salmon farmers worldwide. Norwegian farmers have been facing this challenge at irregular intervals since the very beginning of the industry. This report describes the events on the first fish farm affected

Piscirickettsiosis in Farmed Turbot, Scophthalmus maximus

Journal of Fish Diseases, EarlyView.
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).
