Farmed Escapees Threaten MHC Diversity in Wild Atlantic Salmon

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Wild Atlantic salmon populations in Norway and elsewhere are experiencing long‐term declines driven by reduced marine survival, climate change, impacts from aquaculture, introduction of alien species, and environmental degradation. Understanding how immune diversity is affected by these declines, and thus the ability of Atlantic salmon to ...

Comparing Smolt Production Estimation Methods in Atlantic Salmon (Salmo salar) [PDF]

Over the last 50 years the number of wild Atlantic salmon has declined by more than 50 %, and a better understanding of the survival and recruitment dynamics of wild populations are needed to ensure the right measures are taken to inform management ...

Physiological performance and cardiac morphology of Atlantic salmon reared under slow and fast growth conditions

Aquaculture Reports
Early rearing environment affects performance later in life. In Atlantic salmon (Salmo salar) aquaculture intensive smolt production has been linked to deviating cardiac morphology and increased mortality risks following stressful events during the ...

Infectious hematopoietic necrosis virus (IHNV) in fish and its consequences for fish farming: A comprehensive review

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Viral diseases are a major concern in finfish aquaculture, leading to severe health problems. Infectious hematopoietic necrosis (IHN) is a highly transmissible systemic viral disease that primarily affects salmonids, causing significant mortality and economic losses to the salmonid farming industry.

Cross-tributary analysis of parr to smolt recruitment of Atlantic salmon (Salmo salar)

, 2000
We used estimates of Atlantic salmon (Salmo salar) parr and smolt density, estimated in three tributaries of the West River, Vermont, U.S.A., to determine (i) if smolt recruitment is density dependent or independent of parr density, (ii) if the ...

An assessment of trap efficiency to estimate coho salmon smolt abundance in a small Alaskan stream [PDF]

, 2004
Thesis (M.S.) University of Alaska Fairbanks, 2004Smolt abundance is commonly estimated using trap efficiency-based methods; however, few studies have investigated the accuracy of trap efficiency estimates.

Plasma prolactin and cortisol concentrations during salinity challenge of coho salmon (Oncorhynchus kisutch) at smolt and post-smolt stages

, 1990
Circulating prolactin (PRL) and/or cortisol were measured in relation to hydromineral balance (internal osmotic pressure or plasma Na+ and K+ ) in smolt or post-smolt coho salmon (Oncorhynthus kisutch) to evaluate effects of salinity challenges ...

Management of Atlantic Salmon (Salmo salar) Smolt in the River Shannon, Ireland

, 1995
The River Shannon, Ireland, hydro-electric scheme is described. Catch statistics from smolt index traps, water temperature, and discharge during the smolt migration period are described for the years 1992-1995.

Overlevelse, spredning og vandring i sjøen for simulert rømt lakseparr og smolt fra et landbasert settefiskanlegg [PDF]

, 2011
Hensikten med prosjektet var å undersøke overlevelse og spredning for parr og smolt av opp-drettslaks (Salmo salar L.) fra et landbasert settefiskanlegg (SalMar Settefisk AS, avd. Folla-foss) etter simulert rømning om høsten.
