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 ...

Changes in swimming depths of Atlantic salmon Salmo salar post-smolts relative to light intensity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008-06-22)
Eight hatchery-reared Atlantic salmon Salmo salar post-smolts, implanted with acoustic depth sensing transmitters and manually tracked for 5-12 h in the Hardangerfjord (Norway), spent most of their time (49-99%) at 1-3 m depth during the day, whereas four of seven fish tracked were found close (<0.5 m) to the surface at night, with a strong negative cross-correlation between general swimming depth ...
Mellom marked og nettverk: Om fiskerirekruttering og sysselsettingsystemer i fiske
(Journal article; Tidsskriftartikkel; Peer reviewed, 2008-08-15)
Denne rapporten er skrevet som en del av prosjektet "Networks or markets? The recruitment challenges in future fisheries and marine industries"; finansiert av Norges forskningsråd og Fiskeri og havbruksnæringens forskningsfond. Formålet med rapporten er å presentere kvantitativt datamateriale om sysselsettingssystemet i fiskeflåten. Rapporten bygger på et datamateriale fremskaffet gjennom telefonintervjuer ...
Analysing diet of small herbivores : the efficiency of DNA barcoding coupled with high-throughput pyrosequencing for deciphering the composition of complex plant mixtures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-08-20)
Background: In order to understand the role of herbivores in trophic webs, it is essential to know
what they feed on. Diet analysis is, however, a challenge in many small herbivores with a secretive
life style. In this paper, we compare novel (high-throughput pyrosequencing) DNA barcoding
technology for plant mixture with traditional microhistological method. We analysed stomach
contents of two ...
Spawning coloration and sperm quality in a large lake population of Arctic charr (Salmonidae: Salvelinus alpinus L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
The modern theories of sexual selection predict that male sexual ornaments may have evolved as reliable signals of male fertilization efficiency. However, among the studies of fishes with external fertilization, the results have yielded ambiguous evidence. In the present study, we present data on the phenotypic relationships between red spawning coloration and ejaculate quality (spermatocrit, sperm ...
Gibberellin mediates daylength-controlled differentiation of vegetative meristems in strawberry (Fragaria × ananassa Duch)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-02-11)
Background: Differentiation of long and short shoots is an important developmental trait in
several species of the Rosaceae family. However, the physiological mechanisms controlling this
differentiation are largely unknown. We have studied the role of gibberellin (GA) in regulation of
shoot differentiation in strawberry (Fragaria × ananassa Duch.) cv. Korona. In strawberry,
differentiation of ...
Evaluation of three commercial bovine ELISA kits for detection of antibodies against Alphaherpesviruses in reindeer (Rangifer tarandus tarandus)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-03-09)
Background: The genus <i>Varicellovirus</i> (family <i>Herpesviridae</i> subfamily <i>Alphaherpesvirinae</i>) includes a group of viruses genetically
and antigenically related to bovine herpesvirus 1 (BoHV-1) among which cervid herpesvirus 2 (CvHV-2) can be of importance
in reindeer. These viruses are known to be responsible for different diseases in both wild and domestic animals. Reindeer are ...
Effects of dietary soybean meal, inulin and oxytetracycline on gastrointestinal histological characteristics, distal intestine cell proliferation and intestinal microbiota in Atlantic salmon (Salmo salar L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2007)
Soyabean meal (SBM)-induced enteritis in the distal intestine of the teleost Atlantic salmon (Salmo salar L.) and other salmonids may be considered
a model for diet-related mucosal disorders in other animals and man. The role of the intestinal microbiota in its pathogenesis was explored.
Compared to diets containing fishmeal (FM) as the sole protein source, responses to extracted SBM or the prebiotic ...
Evaluating the impact of scoring parameters on the structure of intra-specific genetic variation using RawGeno, an R package for automating AFLP scoring
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-01-26)
Background: Since the transfer and application of modern sequencing technologies to the analysis of amplified fragment-length polymorphisms (AFLP), evolutionary biologists have included an increasing number of samples and markers in their studies. Although justified in this context, the use of automated scoring procedures may result in technical biases that weaken the power and reliability of further ...
