A comparative study of quality and safety of Atlantic cod (Gadus morhua) fillets during cold storage, as affected by different thawing methods of pre-rigor frozen headed and gutted fish
(Journal article; Peer reviewed, 2017)The catch of marine whitefish is typically seasonal, whereas the land‐based processing industry has a need for all‐year stable supply of raw materials. This challenge can be met by applying fish frozen at sea. When using ... -
A comparison between three Atlantic salmon river stocks; using classical population genetics, differences in life history traits and performance in sea ranching
(ICES CM Documents;1997/P:13, Working paper, 1997)Characterisation of stocks is essential for fisheries and environmental management in order to conserve genetic diversity. However, classical populationgenetic methods frequently fail to document stock differences. In ... -
A comparison of biological trends from four marine ecosystems: synchronies, differences, and commonalities
(ICES CM documents;2007/D:09, Working paper, 2007) -
A comparison of community and trophic structure in five marine ecosystems based on energy budgets and system metrics
(ICES CM documents;2007/D:11, Working paper, 2007)As part of the international MENU collaboration, energy budget models for five marine ecosystems were compared to identify differences and similarities in trophic and community characteristics across ecosystems. We examined ... -
A comparison of gene transcription profiles of domesticated and wild Atlantic salmon (Salmo salar L.) at early life stages, reared under controlled conditions
(Journal article; Peer reviewed, 2014-10-09)Background Atlantic salmon have been subject to domestication for approximately ten generations, beginning in the early 1970s. This process of artificial selection will have created various genetic differences between ... -
A comparison of growth rate of halibut larvae (Hippoglossus hippoglossus L.) fed wild zooplankton and enriched Artemia
(ICES CM Documents;1990/F:60, Working paper, 1990)Halibut larvae at an age of 267 day degrees post hatching, were reared through first feeding, outdoors in 100 l plastic bags. There were three feeding regimes: wild zooplankton, Artemia enriched on the algae Isochrysis ... -
A comprehensive assessment of fish and other seafood in the Norwegian diet.
(VKM Report, Research report, 2006) -
A conservation plan for Atlantic salmon (Salmo salar) and anadromous brown trout (Salmo trutta) in a region with intensive industrial use of aquatic habitats, the Hardangerfjord, western Norway
(Journal article; Peer reviewed, 2013-10-15)Extensive use of aquatic habitats, mainly for hydropower and aquaculture, has a negative impact on anadromous salmonid populations of the Hardangerfjord region, western Norway. High infection levels of salmon lice, and ... -
A contrastive learning approach for individual re-identification in a wild fish population
(Peer reviewed; Journal article, 2023)In both terrestrial and marine ecology, physical tagging is a frequently used method to study population dynamics and behavior. However, such tagging techniques are increasingly being replaced by individual re-identification ... -
A cross-ecosystem comparison of temporal variability in recruitment of functionally analogous fish stocks
(ICES CM documents;2007/D:10, Working paper, 2007)As part of the international MENU collaboration, variability in temporal patterns of recruitment and spawning stock were compared among functionally analogous species from four marine ecosystems including the Gulf of ... -
A dataset of direct observations of sea ice drift and waves in ice
(Peer reviewed; Journal article, 2023)Variability in sea ice conditions, combined with strong couplings to the atmosphere and the ocean, lead to a broad range of complex sea ice dynamics. More in-situ measurements are needed to better identify the phenomena ... -
A field intercomparison between a miniature CTD and the Neil Brown serial 1223 CTD- profiler
(ICES CM Documents;1989/C:24, Working paper, 1989)During a survey in Lofoten in may 1989 a new miniature CTD which is being developed at the Inst. of Marine Research was mounted to the ship`s ordinary serial 1223 CTD- profiler on 10 different CTD- stations. Using the ... -
A field intercomparison between an acoustic current profiler / ADCP and two Savonius type current meters
(ICES CM Documents;1990/C:30, Working paper, 1990)During an introductory experiment in Lofoten May 1990 data from a vessel mounted ADCP on an anchored research vessel were intercompared with corresponding data from two anchored rotor current meters in a region where the ... -
A first assessment of glyphosate, 2,4-D and Cry proteins in surface water of South Africa
(Journal article; Peer reviewed, 2019)Agriculture plays a vital role in the South African economy, as well as in the production of maize for food. Genetically modified maize is transformed to encode for crystalline (Cry) proteins found in Bacillus thuringiensis ... -
