Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

Journal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Seasonal presence, movements and behaviour of Atlantic cod (Gadus morhua) in Isfjorden, Svalbard

Journal of Fish Biology, EarlyView.
Abstract Atlantification is increasing the inflow of warm, salty Atlantic water into the Arctic region. The fjords on the western coast of Svalbard are experiencing Atlantification, enabling boreal species, such as Atlantic cod (Gadus morhua), to expand their distribution northwards.

Revealing potential Atlantic salmon bycatch hotspots from pelagic fisheries landings across the Northeast Atlantic

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) marine survival has declined markedly over the past five decades, leading to concerns about future population viability. While many studies have explored the impacts of stressors such as climate change and predation, less is known about bycatch from pelagic fisheries targeting finfish species.

Effect of Foetal Bovine Serum in Oil‐Adjuvanted Vaccines on Spinal Deformities and Growth in Atlantic Salmon (Salmo salar)

Journal of Fish Diseases, EarlyView.
ABSTRACT Numerous studies have shown that oil‐adjuvanted vaccines (OAV) can induce a variety of different side effects in Atlantic salmon including spinal deformities (SD). Of these, a pathology first described in 2020 and named cross‐stitch vertebrae has been associated with the use of inactivated salmonid alphavirus (SAV) vaccines. Historically, most
