Biomass of Scyphozoan Jellyfish, and Its Spatial Association with 0-Group Fish in the Barents Sea
(Journal article; Peer reviewed, 2012-03-22)An 0-group fish survey is conducted annually in the Barents Sea in order to estimate fish population abundance. Data on jellyfish by-catch have been recorded since 1980, although this dataset has never been analysed. In ... -
Cascading effects of the ctenophore Mnemiopsis leidyi on the planktonic food web in a nutrient-limited estuarine system
(Journal article; Peer reviewed, 2012-07-24)Increasing biomasses of gelatinous zooplankton presumably have major implications for the structure and function of marine food webs at large; however, current data on lower trophic levels are scarce, as most studies ... -
Change in Fish Community Structure in the Barents Sea
(Journal article; Peer reviewed, 2013-04-29)Change in oceanographic conditions causes structural alterations in marine fish communities, but this effect may go undetected as most monitoring programs until recently mainly have focused on oceanography and commercial ... -
Changes in growth of Northeast Arctic cod in relation to food consumption in 1984-1988
(ICES Marine Science Symposia, Journal article; Peer reviewed, 1991)From 1984 to 1988 the average weight of cod (Gadus morhun) by age group in the Northeast Arctic stock was reduced by about 60% in most age groups. During the same period, the estimated individual food consumption by age ... -
Changes in the relationship between sea temperature and recruitment of cod, haddock and herring in the Barents Sea
(Journal article; Peer reviewed, 2013-06-14)Cod, haddock and herring in the Barents Sea have strongly variable recruitment. For these three stocks, earlier studies have suggested a high correlation between their recruitment and a positive relationship between high ... -
Characterization and expression levels of protease enzymes at different developmental stages of Siamese fighting fish (Betta splendens Regan, 1910)
(Journal article; Peer reviewed, 2010-05)Characterization of total proteases, trypsin and chymotrypsin were performed at pH 2 12 and temperatures 20-80°C in three life stages of Siamese fighting fish (Betta splendens Regan, 1910). At least fourteen protease ... -
Cod, haddock, saithe, herring, and capelin in the Barents Sea and adjacent waters: a review of the biological value of the area
(Journal article; Peer reviewed, 2009-10-09)Cod, haddock, saithe, herring, and capelin are the most important fish species in the Barents Sea and adjacent waters. Ecosystem-based management requires species-specific knowledge of the biological value and vulnerability ... -
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 ... -
The combined impact of plant-derived dietary ingredients and acute stress on the intestinal arachidonic acid cascade in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2010-03)A study was conducted to assess the effect of substituting high levels of dietary fish oil (FO) and fishmeal (FM) for vegetable oil (VO) and plant protein (PP) on the intestinal arachidonic acid (AA) cascade in the carnivorous ... -

Decline and Recovery of Atlantic Cod (Gadus morhua) Stocks throughout the North Atlantic
(Chapter, 2008)Many stocks of Atlantic cod (Gadus morhua) on both sides of the North Atlantic are currently at much reduced levels of biomass, but this situation is not in all instances the result of long, continuous decline. Most Northwest ... -
Deep Vision: An In-Trawl Stereo Camera Makes a Step Forward in Monitoring the Pelagic Community
(Journal article; Peer reviewed, 2014-11-13)Ecosystem surveys are carried out annually in the Barents Sea by Russia and Norway to monitor the spatial distribution of ecosystem components and to study population dynamics. One component of the survey is mapping the ... -
Deformities in larvae and juvenile European lobster (Homarus gammarus) exposed to lower pH at two different temperatures
(Journal article; Peer reviewed, 2013-12-04)The ongoing warming and acidification of the world's oceans are expected to influence the marine ecosystems, including benthic marine resources. Ocean acidification may especially have an impact on calcifying organisms, ... -

Density-dependent growth as a key mechanism in the regulation of sh populations: evidence from among-population comparisons
(Journal article; Peer reviewed, 2001-11-30)It is generally assumed that fish populations are regulated primarily in the juvenile (pre-recruit) phase of the life cycle, although density dependence in growth and reproductive parameters within the recruited phase has ... -
Description of a new goatfish species, Upeneus randalli n. sp. (Mullidae), from the Persian Gulf, with remarks and identification keys for the genus Upeneus
(Journal article; Peer reviewed, 2011-09)The number of species of the goatfish genus Upeneus from the western Indian Ocean has increased considerably due to recent taxonomic efforts. Here we describe a new species, Upeneus randalli n. sp., based on body and fin ... -
Detecting Atlantic herring by parametric sonar
(Journal article; Peer reviewed, 2010-03-17)The difference-frequency band of the Kongsberg TOPAS PS18 parametric sub-bottom profiling sonar, nominally 1–6 kHz, is being used to observe Atlantic herring. Representative TOPAS echograms of herring layers and schools ...
