Fish silage hydrolysates: Not only a feed nutrient, but also a useful feed additive
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-06)
Background:<br>
Processing of fish and shellfish may result in substantial amounts of by-products and unless they can be used as food, the most realistic option in most cases is the production of preserved feed nutrients. If large volumes are available, reduction to fishmeal and fish oil is the preferred technology. However, fresh by-products are most often available in insufficient quantities ...
Intensive aquaculture and sustainable regional development in the Arctic region – from controversy to dialogue (AquaLog)
(Research report; Forskningsrapport, 2017-08-28)
The main objective of the AquaLog project is to understand factors and forces that influence the aquaculture controversy in the Arctic communities. This report summarizes the second workshop in Vancouver, Canada 23-27th April 2017. The project is funded by the Nordic Council of Minister and the Norwegian Fram Centre.
Risk assessment of radioactivity in Food. Opinion of the Scientific Committee of the Norwegian Scientific Committee for Food Safety, VKM report 2017:25
(Research report; Forskningsrapport, 2017-08-23)
Since 1986, the management of radioactive contamination in food and feed in Norway has
been driven mainly by the Chernobyl Disaster follow-up. Monitoring and countermeasures
are still in place to reduce the exposure to the population. The Norwegian Food Safety
Authority is in the process of revising the maximum levels (MLs) for radioactive substances in
drinking water and food and establishing ...
The effect of algae diets (Skeletonema costatum and Rhodomonas baltica) on the biochemical composition and sensory characteristics of Pacific cupped oysters (Crassostrea gigas) during land-based refinement
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-20)
<p>Oyster refinement, a common practice in France, is aimed at increasing the weight of oyster tissue and influencing the taste properties of the refined oysters. Refinement usually takes place in land-based systems where the oysters are fed with relatively high concentrations of microalgae. In this study the impact of feeding <i>Skeletonema costatum</i> and <i>Rhodomonas baltica</i> on the biochemical ...
Seasonal and yearly variation of total polyphenols, total anthocyanins and ellagic acid in different clones of cloudberries (Rubus chamaemorus L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-02)
Cloudberry (Rubus chamaemorus L.) is a wild perennial shrub growing on peatland with a circumpolar distribution. The combined berries have a high polyphenol content comprised primarily of ellagitannins. A few commercial cultivars are available, and pre-breeding trials on clonal material from different geographical origins are in progress. The objective of this study was to investigate how the content ...
Parasitism and the Biodiversity-Functioning Relationship
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-15)
Species interactions can influence ecosystem functioning by enhancing or suppressing the activities of species that drive ecosystem processes, or by causing changes in biodiversity. However, one important class of species interactions – parasitism – has been little considered in biodiversity and ecosystem functioning (BD-EF) research. Parasites might increase or decrease ecosystem processes by ...
Narrow lenses for capturing the complexity of fisheries: A topic analysis of fisheries science from 1990 to 2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-20)
Despite increased fisheries science output and publication outlets, the global crisis in fisheries management is as present as ever. Since a narrow research focus may be a contributing factor to this failure, this study uncovers topics in fisheries research and their trends over time. This interdisciplinary research evaluates whether science is diversifying fisheries research topics in an attempt ...
A Novel brominated Alkaloid Securidine A, Isolated from the Marine Bryozoan Securiflustra securifrons
(Conference object; Konferansebidrag, 2017)
A novel brominated alkaloid, Securidine A, was isolated from the cold water marine bryozoan Securiflustra securifrons. Securidine A was isolated using semi-preparative HPLC, and the structure was elucidated by spectroscopic methods. The isolated Securidine A was tested for cytotoxic, antibacterial, and anti-diabetic activities as well as for its potential for inhibition of biofilm formation. No ...
Effect of lifting the sweeps on bottom trawling catch efficiency on the Northeast arctic cod trawl fishery
(Research report; Forskningsrapport, 2014)
Fuel consumption and environmental concerns have led bottom trawlers fishing for cod (Gadus morhua) in the Barents Sea to use semi-pelagic doors. However, this change may affect fish herding and consequently the catch efficiency of the gear. In this study we compared the catch efficiency of two different setups where the sweep length with bottom contact was different. This setup also enabled us to ...
Valuing coastal recreation and the visual intrusion from commercial activities in Arctic Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-04)
The coastal zone in the Arctic is being extensively used for recreational activities. Simultaneously, there is an
increasing pressure from commercial activities. We present results from a discrete choice experiment implemented
in Arctic Norway, revealing how households in this region make trade-offs between recreational
activities and commercial developments in the coastal zone. Our results show ...
