Marine pollution by lost, abandoned or otherwise discarded fishing gear (ALDFG) often has negative impact on the ecosystem through plastic pollution and continuous capture of marine animals, so-called “ghost fishing”. ALDFG in pot fisheries is associated with high ghost fishing risk. The snow crab (Chionoecetes opilio) pot fishery is conducted in harsh weather conditions increasing the risk of ...

The management of the Norwegian Northeast Atlantic cod fishery has in many ways been a success story; quotas have been high (but now declining), profitability has been higher than most other industries and there is great interest among young recruits to enter the fishery. However, over the last decade illegal fishing of allocated quotas and black-market transactions throughout the value chain ...

The new guanidine based alkaloid Dendrobeaniamine A was isolated from the organic crude extract of the Arctic marine bryozoan <i>Dendrobeania murrayana</i>. The structure was determined by interpretation of data from 1D and 2D NMR spectroscopic methods and mass spectrometry (HR-MS) analysis. Dendrobeaniamine A did not show any biological activities in the applied bioassays. Further bioactivity ...

The purpose of the presentation is to give an overview of the status of environmental assessments in international law, and to review the progress of a global and a regional process in trying to improve the current regime.   The international regime for environmental impact assessments (EIA) in the Arctic Ocean is symptomatic for the situation in most regional seas. There is a predominance of ...

The objective of this study was to examine the effects of CO₂, total ammonia nitrogen (TAN: nitrogen bound as either NH₃ or NH₄⁺) and pH on the growth and survival of juvenile lumpfish in a two-month growth study. The results demonstrate the complex interactions of these water quality variables. The specific growth rate (SGR) of the lumpfish was progressively ...

Driftwood is woody debris that is floating on the sea or brought onto the shore by the sea. It can have a natural origin but often it originates from human activities. Driftwood has a significant ecological role as a microhabitat for a large range of species. Dead-wood-associated aphyllophoroid fungi on driftwood have been studied rather little globally, and there are hardly any studies conducted ...

The intestinal mucosal barrier plays a critical role in the maintenance of host health. In farmed teleost fish, the intestinal epithelium is challenged by a number of factors, leading to damage of the intestinal mucosal barrier. The pathogenesis of intestinal mucosal barrier damage in most farmed teleost fish has been associated with cell death, mainly including apoptosis, pyroptosis, necroptosis ...

An image is what we have in our head and what we make up in an allegory, a name, a metaphor, a text, a map or in a drawing. None of these should be confused with the thing that is being imagined. They are not the real thing, just our imaginations of it. Still, we could not do without them, for instance when governing small-scale fisheries. They make us understand what we are up to and the track we ...

Presentasjon av institusjonelle utviklingstrekk i fiskeri- og havbruksforvaltning. Samspill mellom regulering, næringstilpasning og teknologi.

Parallelt med tiltagende lukking av de store fiskeriene i Norge, har det skjedd en nedgang i antall fiskere, samtidig som også færre rekrutteres til fiske. Spørsmålet her er om fiskere har blitt skjøvet ut av yrket eller om de har sluttet av andre grunner? En undersøkelse blant fiskere som har sluttet, tyder på at utviklinga i andre næringer og i samfunnet har hatt innvirkning på sysselsettingssystemet ...
