A model system for studying lipid oxidation of salted cod muscle was used for investigating the interaction effects of including antioxidants and copper in the brine. The results showed that ascorbate might have pro-oxidative or anti-oxidative effects depending on the ascorbate and metal concentrations. Without added copper in the brine, concentrations of ascorbate ≤500 ppm had a pro-oxidative effect. ...

The effects of the rigor state and freezing of cod prior to salting on the mass transfer during production and the quality of heavily cured cod have been investigated. Pre-rigor salting lead to a larger reduction in weight, a higher water loss and a lower uptake of NaCl than in fish salted post-rigor and in fish salted after frozen storage. The cause of this is believed to be the simultaneous influx ...

Regional analyses of possible physical and biological effects of global warming in the Barents Sea area have been carried out recently. Based on such studies possible economic impacts of global warming on the Barents Sea fisheries have been quantified, assuming different types of management regimes. The EconSimp2000 model, consisting of the ecosystem model AggMult and the fleet model EconMult have ...

A thorough review of different aspects on the health implications of using vegetable feed ingredients, both protein and lipid alternatives to fishmeal and fish oil, plus possible additions of immunostimulants, also including a short chapter on undesirable components, the use of genetically modified plants, and how processing may affect feed quality and availability, are given in the different chapters ...

This paper discusses power relations in the production of knowledge claims and the validation of management strategies. The experience of doing stock assessment science and creating management plans for Canada’s east coast cod fishery illustrates this general process. We demonstrate that the cyborgization of fisheries-management is limited by its inability to produce power for stabilizing the ...

Although natural resource exploitation has a long tradition, modern resource management is a more recent phenomenon. The huge variety in natural resource exploitation has made it difficult to place the industrial harvesting of marine living resources under political and managerial control. For most of history fish and fishing people have for all practical purposes been unmanageable. From the late ...

This paper discusses actual and possible achievements and failures of Codland and examines it from the point of view of efficiency and in terms of distribution. It is argued in favour of the joint analysis of the two approaches when contemplating fisheries management reforms, since such reforms may create both winners and losers. The analysis demonstrates how rent drain from fishing communities and ...

Fisketurismen – nye aktører i kystsamfunn? Hvert år deltar flere tusen fiskere i vårtorskefisket utenfor Lofoten og Vesterålen. Når skreien kommer inn til kysten i januar/februar for å gyte, starter det årlige eventyret som kalles Lofotfisket. Fiskerne tar i løpet av noen måneder opp rundt 40 000 tonn fisk. Men det er ikke bare yrkesfiskerne som strømmer til området under sesongen. Også turistene ...
