Prevalence of piscine orthoreovirus and salmonid alphavirus in sea-caught returning adult Atlantic salmon (Salmo salar L.) in northern Norway
(Peer reviewed; Journal article, 2018-05)Heart and skeletal muscle inflammation (HSMI) caused by piscine orthoreovirus (PRV) and pancreas disease (PD) caused by salmonid alphavirus (SAV) are among the most prevalent viral diseases of Atlantic salmon farmed in ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Peer reviewed; Journal article, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
Snorkel sea-cage technology decreases salmon louse infestation by 75% in a full-cycle commercial test
(Peer reviewed; Journal article, 2019-09-13)Methods to prevent parasite infestations in farmed fish are becoming widespread, yet tests of their effectiveness often lack commercial relevance and statistical power, which may lead to technology misuse. Here, we examined ... -
Surface environment modification in Atlantic salmon sea-cages: Effects on amoebic gill disease, salmon lice, growth and welfare
(Peer reviewed; Journal article, 2018)Surface environment modification is a potential parasite control strategy in Atlantic salmon sea-cage farming. For instance, a temporary low salinity surface layer in commercial-scale snorkel sea-cages has coincided with ... -
Timing and selectivity of mortality in reared Atlantic cod revealed by otolith analysis
(Peer reviewed; Journal article, 2010-11-03)In juvenile fish production, large samples of known-aged material can be sampled at pre-determined time intervals from the same population. This enables an accurate determination of size-selective mortality by means of ...
