Changes in benthic sediment conditions under an atlantic salmon farm at a deep, well-flushed coastal site
(Journal article; Peer reviewed, 2014-02-27)Along the Norwegian coastline, it is predicted that salmonid aquaculture will rapidly expand in the coming years, exceeding current production levels of 1.3 million t in 2012. This will result in increased interactions ... -
Characterisation of two vitellogenins in the salmon louse Lepeophtheirus salmonis: molecular, functional and evolutional analysis
(Journal article; Peer reviewed, 2011-05-09)The salmon louse Lepeophtheirus salmonis Krøyer affects a variety of wild salmonoid hosts, but is also an important pest in aquaculture, which is a globally important and rapidly growing industry. Salmon lice have large ... -
Characterization of Digestive Enzymes from Adult Freshwater Pearl Mussel Chamberlainia hainesiana (Lea, 1856)
(Journal article; Peer reviewed, 2009)Freshwater mussel Chamberlainia hainesiana is a vulnerable species in Thailand. The species has a lustrous nacreous shell that can be utilized for various purposes, and has a potential industrial use for producing freshwater ... -
Chemoreception in the salmon louse Lepeophtheirus salmonis: an electrophysiology approach
(Journal article; Peer reviewed, 2007-12-13)The search for effective and long-term solutions to the problems caused by salmon lice Lepeophtheirus salmonis (Krøyer, 1837) has increasingly included biological/ecological mechanisms to combat infestation. One aspect of ... -
Coastal salmon farms attract large and persistent aggregations of wild fish: an ecosystem effect
(Journal article; Peer reviewed, 2009-06-18)Coastal aquaculture is a globally expanding enterprise. Currently, 1200 salmon farms operate in coastal Norway, yet their capacity to aggregate and subsequently modify wild fish distributions is poorly known. Aggregations ... -
Cod and climate: effect of the North Atlantic Oscillation on recruitment in the North Atlantic
(Journal article; Peer reviewed, 2006-11-07)The impact of the environment on interannual variability in fish recruitment has proven difficult to establish empirically, and environment-recruitment correlations have often been found to break down when more data become ... -
Collagen type XI 1 may be involved in the structural plasticity of the vertebral coulm in Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2010)Atlantic salmon (Salmo salar L.) vertebral bone displays plasticity in structure, osteoid secretion and mineralization in response to photoperiod. Other properties of the vertebral bone, such as mineral content and mechanical ... -
Copepod production in a saltwater pond system: A reliable method for achievement of natural prey in start-feeding of marine fish larvae
(Journal article; Peer reviewed, 2014-07-23)A high-latitude seawater pond system was restarted after 10 years absence of controlled biological production. Water supply systems for emptying and refilling the 25,000 m3 pond were installed along with a wheel filter ... -
Coping with Unpredictability: Dopaminergic and Neurotrophic Responses to Omission of Expected Reward in Atlantic Salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2014-01-17)Comparative studies are imperative for understanding the evolution of adaptive neurobiological processes such as neural plasticity, cognition, and emotion. Previously we have reported that prolonged omission of expected ... -
Density-dependent migratory waves in the marine pelagic ecosystem
(Journal article; Peer reviewed, 2006-11)The migration of large aggregations of animals that sweep through the landscape is a phenomenon with large consequences in many ecosystems. It has been suggested that such migrations are mediated by resource depletion. ... -
Depth distribution of the amoebic gill disease agent, Neoparamoeba perurans, in salmon sea-cages
(Journal article; Peer reviewed, 2015-07-16)Identifying where and when parasites occur in farming environments is vital to understand transmission dynamics and develop preventative measures that reduce host-parasite encounters. A major parasite concern for Atlantic ... -
Detection of the myxosporean parasite Parvicapsula pseudobranchicola in Atlantic salmon (Salmo salar L.) using in situ hybridization (ISH)
(Journal article; Peer reviewed, 2015-02-15)Parvicapsula pseudobranchicola is a marine myxosporean parasite infecting farmed Atlantic salmon (Salmo salar). A major site for the parasite is the pseudobranch, which may be destroyed in heavily infected fish. Parvicapsulosis ... -
Diel vertical migration patterns in juvenile cod from the Skagerrak coast
(Journal article; Peer reviewed, 2010-04-29)We demonstrated a clear year-round diel vertical migration pattern (DVM) of small (26 to 45 cm) Skagerrak coastal cod Gadus morhua on a small geographic scale. Generalized additive models (GAMs) were used to make inferences ... -
Direct and indirect climate forcing in a multi-species marine system
(Journal article; Peer reviewed, 2010-10)Interactions within and between species complicate quantification of climate effects, by causing indirect, often delayed, effects of climate fluctuations and compensation of mortality. Here we identify direct and indirect ... -
Disease interaction and pathogens exchange between wild and farmed fish populations with special reference to Norway
(Journal article; Peer reviewed, 2011-05-21)Norway has the largest salmon-farming industry in the world, an industry that is still growing, and in recent years production of marine species like Atlantic cod has also increased. At the same time, Norway has the world's ... -

Distribution of sex and age groups of ringed seals Pusa hispida in the fast-ice breeding habitat of Kongsfjorden, Svalbard
(Journal article; Peer reviewed, 2007-04-16)Spatial distribution of various age- and sex groups of ringed seals (N = 94; 19 adult males, 33 adult females and 42 subadults) was studied in their fast-ice breeding habitat in Kongsfjorden, Svalbard, during May 2004. ... -
Drift, growth, and survival of larval Northeast Arctic cod with simple rules of behaviour
(Journal article; Peer reviewed, 2007-10-11)Due to vertical variations in ocean circulation, larval Northeast Arctic cod Gadus morhua may influence their own drift routes by migrating vertically. By coupling a larval individual-based model and a general circulation ... -
Economic repercussions of fisheries-induced evolution
(Journal article; Peer reviewed, 2013-07-23)Fish stocks experiencing high fishing mortality show a tendency to mature earlier and at a smaller size, which may have a genetic component and therefore long-lasting economic and biological effects. To date, the economic ... -
