Rapporten oppsummerer hvordan prosessering kan påvirke innholdet av næringsstoffer i sjømat, samt hvordan biotilgjengeligheten til ulike stoffer kan endres som følge av prosessbetingelsene. I tillegg er det kort redegjort for vitenskapelig status på helseeffektene av sjømatkonsum, samt hvilke ernæringsmessige faktorer som gjør sjømat til et særegent næringsmiddel. Økt prosesseringsgrad av sjømat ...

Fisheries are characterized by variations in space and time. This study investigates the characteristics of seasonality in cod trawl fisheries in two distinct areas: the coast along the northern Norway and the high sea area of the Barents Sea. Catch per unit effort (CPUE) is used to proxy variation in stock abundance. A CPUE function has been estimated in the frequency‐domain framework, to detect ...

Ecosystem-based fisheries management seeks to expand upon the traditional one-stock fisheries management measures by internalizing the effects of fishing on marine ecosystems, and accounting for biological interactions among marine resources. The fact that marine resources provide multiple, often competing benefits, makes the accomplishment of these ecosystem-based fisheries management objectives ...

Turgencin A, a potent antimicrobial peptide isolated from the Arctic sea squirt <i>Synoicum turgens</i>, consists of 36 amino acid residues and three disulfide bridges, making it challenging to synthesize. The aim of the present study was to develop a truncated peptide with an antimicrobial drug lead potential based on turgencin A. The experiments consisted of: (1) sequence analysis and prediction ...

Climate change and declining sea-ice in the Central Arctic Ocean (CAO) has brought concerns that fish stocks may expand into the high Arctic. While the sub-Arctic seas of the North Pacific and the North Atlantic have abundant fish resources subject to major commercial fisheries for generations, the CAO has little or none. Concerns that fish stocks could expand into the CAO provided the impetus for ...

The North Sea brown shrimp (<i>Crangon crangon</i> Linnaeus, 1758) fishery became Marine Stewardship Council (MSC) certified in 2017. As part of the certification, the fishermen proposed to incrementally increase the mesh size of the codend used from 22 mm to 26 mm. As this increase in mesh size could result in a substantial loss of marketable sized brown shrimp (shrimp with total length equal or ...

Siderophores are compounds with high affinity for ferric iron. Bacteria produce these compounds to acquire iron in iron-limiting conditions. Iron is one of the most abundant metals on earth, and its presence is necessary for many vital life processes. Bacteria from the genus <i>Serratia</i> contribute to the iron respiration in their environments, and previously several siderophores have been isolated ...

Games are vehicles that transport their players between different realties (Peters & Westelaken 2014). By doing this, they have the potential to provide many different benefits for their players, such as relaxation, excitement, social interaction, and learning. Higher education is increasingly trying to capitalize on this potential and many teachers now make use of different forms of game-based learning ...

This work contains a review of the undesirable substances that may be introduced as contaminants of natural and malicious origin, and of emerging hazards, in the production chain of farmed salmon,from ova to packed fillet.<p><p> The work, focused in the supply chain to European countries, contains a brief introduction to general food safety in relation to aquaculture products, followed by an ...

The Norwegian Scientific Committee for Food Safety (VKM) has been asked by the Norwegian Food Safety Authority to perform a health risk assessment on decomposition substances and oxidation products in fish oils intended for human consumption except pharmaceuticals. Seal and/or krill oil intended for human consumption might be included but in separate chapters. EU’s hygiene regulations for the ...
