Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats.

Fish Poxviruses on the Rise: Prospects for Aquatic Health
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.

Results from AIC selected smolt survival model.
Expected marine survival is shown in relation to length for age-1 (blue) and age-2 (red) smolts. Light colored lines show predicted survival as a function of length for each age in each year (random intercepts from model SAS-1R). Bold lines indicate mean

ABSTRACT Waterborne horizontal transmission of viral diseases in fish relies on the release of infectious virus particles (termed shedding) into the aquatic environment. Both the rate and duration of shedding are critical for efficient viral spread, making interventions that reduce shedding valuable for disease control.

Decoding the Black Box of Fish Vaccines Efficacy in Basic and Applied Contexts
ABSTRACT Vaccines are the frontline defense in aquaculture, yet predicting their real‐world performance remains a tricky puzzle. Unlike terrestrial veterinary vaccines, fish vaccines largely operate through “Black Box” processes, where we observe the outcomes but rarely understand the underlying immune mechanisms. Laboratory trials, though informative,

A decade of data on wild steelhead trout (Salmo gairdneri) from a coastal stream in British Columbia demonstrated large fluctuations in smolt number, age structure, size, estimates of adult run sizes, smolt-to-adult survival, and adult age.

The Value of Mono-gender Smolt in Atlantic Salmon farming
I oppgaven undersøkes det hvorvidt mono-kjønnet smolt kan skape ekstra verdi i oppdrett av atlantisk laks. Det gjøres ved å sammenlikne produksjonseffektiviteten og den operasjonelle risikoen ved produksjon av ulike sammensetninger av mono-kjønnet og ...
