A Novel Brominated Alkaloid Securidine A, Isolated from the Marine Bryozoan Securiflustra securifrons
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-23)
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 ...
Carbon, Nitrogen and Sulphur isotopic fractionation in captive juvenile hooded seal (Cystophora cristata): application for diet analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-15)
<p><i>Rationale</i>: Intrinsic biogeochemical markers, such as stable isotope ratios of carbon, nitrogen and sulphur, are increasingly used to trace the trophic ecology of marine top predators. However, insufficient knowledge of fractionation processes in tissues continues to hamper the use of these markers.</p>
<p><i>Methods</i>: We performed a controlled feeding experiment with eight juvenile ...
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 ...
A Novel brominated Alkaloid Securidine A, Isolated from the Marine Bryozoan Securiflustra securifrons

Informing management strategies for a reserve: Results from a discrete choice experiment survey
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-18)
It is well-known that operating within the boundaries of a national park provides commercial actors with the opportunity to charge a price premium, though this has to a lesser degree been demonstrated for marine protected areas. We estimate national tourists' willingness-to-pay a price premium for boat trips in the Nha Trang Bay Marine Protected Are, Vietnam, using a discrete choice experiment. Our ...
Peptide from sea anemone metridium senile affects transient receptor potential ankyrin-repeat 1 (TRPA1) function and produces analgesic effect
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-11)
The Transient Receptor Potential Ankyrin-repeat 1 (TRPA1) is an important player in pain and inflammatory pathways. It is a promising target for novel drugs development for treatment of a number of pathological states. A novel peptide producing significant potentiating effect (up to ~90%) on AITC- and diclofenac-induced currents of TRPA1 was isolated from the venom of sea anemone <i>Metridium ...
Recovery from exhaustive swimming and its effect on fillet quality in haddock (Melanogrammus aeglefinus)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-08)
Wild haddock (<i>Melanogrammus aeglefinus</i>) of commercial size (0.8–2.49 kg, 45–60 cm) were swum to exhaustion in a large swim tunnel and then allowed to recuperate for 0, 3 or 6 h, to investigate the effects of exhaustive swimming on blood glucose, blood lactate and post mortem development of fillet quality. There was a positive linear relationship between critical (aerobic) swimming speed ...
