Transcription of reference genes used for quantitative RT-PCR in Atlantic salmon is affected by viral infection
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Relative quantification using RT-qPCR is a widely used method for transcription profiling. Transcript levels of target genes in fish after experimental infection is often reported without documentation of stably transcribed reference genes. We present results demonstrating that transcription of typically used reference genes in Atlantic salmon is not stable during experimental infection with salmon ... -
Dynamics of bacterial community exposed to hydrocarbons and oleophilic fertilizer in high-Arctic intertidal beach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Exposure of pristine microbial environments to hydrocarbon contamination stimulates growth of the initially small fraction of indigenous hydrocarbon-degrading bacteria. Custom-made oleophilic fertilizers have been demonstrated to promote oil bioremediation by boosting this proliferation. In the present study, the temporal dynamics of the bacterial community structure and the individual influences ... -
Evaluation of probiotic strain Bacillus subtilis C-3102 as a feed supplement for koi carp (Cyprinus carpio)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)In this study, the effects of dietary probiotic Bacillus subtilis C-3102 (Calsporin®) on the growth performance, predominant intestinal microbiota, expression of cytokines genes in three organs (liver, intestine and kidney) and protection against Aeromonas hydrophila infection of koi carp were investigated. Fish were fed two different diets, 1-control diet (non-supplemented) and 2-experimental diet ... -
Evaluation of prebiotic and probiotic effects on the intestinal gut microbiota and histology of Atlantic salmon (Salmo salar L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)In the present study the impact on gut microbiology and indigenous gut histology of Atlantic salmon (Salmo salar L.) was investigated following feeding of a control and a prebiotic (EWOS prebiosal®) diet and ex vivo exposure to saline or the probiotic bacterium Carnobacterium divergens. The results showed that ex vivo exposure of C. divergens at 108 CFU ml-1 did not cause cell damage to the intestine ... -
Do stocking densities affect the gut microbiota of gibel carp (Carassius auratus gibelio) cultured in ponds?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)The aim of the present study was to evaluate the intestinal microbial communities of gibel carp (Carassius auratus gibelio) cultivated in two beach ponds at different stocking densities. The two ponds were both ~3.33 hm2 in acreage and ~1.5 m in depth. The stocking densities included one intensive with 2 fish m–3 while the other treated as semi-intensive with 1 fish m–3. The gut microbiota (both ... -
The ecological and economic value of cold-water coral ecosystems
(Journal article; Tidsskriftartikkel, 2010)Despite the growing scientific literature on cold-water corals (CWC) there appears to be no studies that address the economic values or economic management of the resource. This paper presents an overview of the goods and services of CWC and their associated biodiversity. Use and non-use values associated with CWC are presented, and the methods relevant for assessing their valuation are discussed. ... -
The evolution of the “harvest machinery” : why capture capacity has continued to expand in Norwegian fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005)Controlling the expansion of capture capacity has been a major challenge for the fisheries management systems around the North Atlantic. Despite focused attempts to reduce this capacity in recent years in different jurisdictions, it has continued to expand. This chapter uses a case study of changes in Norwegian fisheries to help explain why this has happened. The article supports the replacement of ... -
A bioeconomic MPA study based on cellular automata population growth and distribution
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)This paper investigates possible biological and economic effects of using marine sanctuaries as a management tool, employing cellular automata techniques to model biological growth and area distribution, assuming open access to the fish stock resources outside the protected area. The cellular automata model incorporates a fish harvest model based on standard assumptions. In agreement with previous ... -

Effects of antioxidants on copper induced lipid oxidation during salting of cod (Gadus morhua L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2003-12-02)A model system for studying lipid oxidation of salted cod muscle was used for investigating the interaction effects of including antioxidants and copper in the brine. The results showed that ascorbate might have pro-oxidative or anti-oxidative effects depending on the ascorbate and metal concentrations. Without added copper in the brine, concentrations of ascorbate ≤500 ppm had a pro-oxidative effect. ... -
Effects of calcium, magnesium and pH during salt curing of cod (Gadus morhua L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2004-01-08)The quality of heavily salted cod was investigated as influenced by adjusted levels of calcium, magnesium and pH in the salt. The investigation was carried out as a multivariate study consisting of two separate 23 full factorial designs. The chemical composition, waterholding capacity, weight and protein yields, colour and firmness were used as quality indicators or responses to the salt mixtures ... -
Physical and Quality Attributes of Salted cod (Gadus morhua L.) as Affected by the State of Rigor and Freezing Prior to Salting
(Journal article; Tidsskriftartikkel; Peer reviewed, 2004-03-04)The effects of the rigor state and freezing of cod prior to salting on the mass transfer during production and the quality of heavily cured cod have been investigated. Pre-rigor salting lead to a larger reduction in weight, a higher water loss and a lower uptake of NaCl than in fish salted post-rigor and in fish salted after frozen storage. The cause of this is believed to be the simultaneous influx ... -
Optimal Selection and Effort in a Fishery on a Stock with Cannibalistic Behaviour : The Case of the Northeast Arctic Cod Fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2010)We explore a fishery targeting the mature part of a stock, while bycatching the immature part. Both targeted catch and bycatch may have positive market values. Cost of effort is supposed to be a function of the selection properties of the fishing gears. Mature fish is assumed to cannibalise on the immature part of the stock. A bioeconomic model of the problem is set up and it is shown that the model ...
