Tracing fish farm waste in the northern shrimp Pandalus borealis (Kroyer, 1838) using lipid biomarkers
(Journal article; Peer reviewed, 2012-02-08)
A large amount of organic effluents are released annually from coastal fish farming locations primarily in the form of faeces that settle to the seabed, where they become a substantial food source for benthic communities. ...
Seatrout (Salmo trutta) is a natural host for Parvicapsula pseudobranchicola (Myxozoa, Myxosporea), an important pathogen of farmed Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2015-04-10)
Background: Parvicapsula pseudobranchicola (Myxozoa) causes widespread infections in farmed Atlantic salmon in northern Norway. Heavily infected salmon become runts, probably due to vision impairment or blindness. The salmon ...
Use of fatty acid profiles to monitor the escapehistory of farmed Atlantic salmon
(Journal article; Peer reviewed, 2015-05-18)
Farmed Atlantic salmon can escape from fish farms at various stages of their life, from juveniles to large mature fish. Escapees that enter rivers to spawn pose a threat to the genetic integrity of wild populations. Knowledge ...
Effects of Pumping Height and Repeated Pumping in Atlantic Salmon Salmo salar
(Journal article; Peer reviewed, 2016-06-17)
The aim of this study was to evaluate the effects of pumping height and repeated pumping on the generalized stress response and gross injuries in harvest sized Atlantic salmon. Fish pumped from a net pen at either high ...
Atlantic salmon Salmo salar instantaneously follow vertical light movements in sea cages
(Journal article; Peer reviewed, 2015)
Atlantic salmon in marine farming environments are exposed to potentially detrimental conditions through space and time. For instance, the vertical distribution of parasitic salmon lice larvae shifts in response to changing ...
Efficiency and catch dynamics of collapsible square and conical crab pots used in the red king crab (Paralithodes camtschaticus) fishery
(Journal article; Peer reviewed, 2008)
Toward a model-based prediction system for salmon lice infestation pressure
(Journal article; Peer reviewed, 2016-09-08)
High salmon lice density is a threat to wild and farmed salmonid fish in Norway. To assess and identify areas for high salmon lice infestation pressure, continuous monitoring is necessary. The national Norwegian salmon ...
Nearby farms are a source of lice for wild salmonids: a reply to Jansen et al. (2016)
(Journal article; Peer reviewed, 2016-05-17)
Jansen et al. (2016; Aquacult Environ Interact 8:349-350) question the regression analysis presented in Serra-Llinares et al. (2014; Aquacult Environ Interact 5:1-16), which correlates lice abundances on farmed and wild ...
Effects of photoperiod and melatonin implants on feed intake in Atlantic salmon (Salmo salar L.) postsmolts
(Journal article; Peer reviewed, 2015-09-15)
High melatonin concentrations were expected to negatively affect Atlantic salmon appetite. Hence, individually kept Atlantic salmon postsmolts were subjected to continuous light (24:0, L:L) or natural daylight (12:12, L:D) ...
Iodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
(Journal article; Peer reviewed, 2013-02-19)
Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential ...
