<p>Fisheries Stakeholders are understandably most concerned with immediate problems. Often these problems are related to proposed rule changes. This short term focus is in itself a serious problem for introducing Ecosystems Based Fisheries Management (EBFM), which is typically seen as a long-term approach. However, the short-term response of fishers to rule changes may well have long-term consequences ...

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 ...

Anticipating future changes in marine social‐ecological systems (MSES) several decades into the future is essential in the context of accelerating global change. This is challenging in situations where actors do not share common understandings, practices, or visions about the future. We introduce a dedicated scenario method for the development of MSES scenarios in a participatory context. The objective ...

In a paper in this journal entitled “Fear and loathing of the deep sea: why don’t people care about the deep sea?”, Jamieson et al. (2020) pose this question and answer it with many interesting perspectives from psychology, ocean literacy and philosophy. However, there is an inherent assumption in the question they ask that people do not care about the deep sea. In order to assess this assumption, ...

Nicotinic acetylcholine receptors (nAChRs) play an important role in the functioning of the central and peripheral nervous systems, and other organs of living creatures. There are several subtypes of nAChRs, and almost all of them are considered as pharmacological targets in different pathological states. The crude venom of the sea anemone Metridium senile showed the ability to interact with ...

The introduction of the Nordmøre grid to shrimp trawls has reduced the issue of bycatch to that of small-sized species and juveniles that are able to pass through the grid and enter the small-meshed cod end together with the targeted shrimp. This study estimated the size- and species-selective performance of the Nordmøre grid in the configuration most often applied by fishermen and made a preliminary ...

As environmental DNA (eDNA) becomes an increasingly valuable resource for marine ecosystem monitoring, understanding variation in its persistence across contrasting environments is critical. Here, we quantify the breakdown of macrobial eDNA over a spatio-temporal axis of locally extreme conditions, varying from ocean-influenced offshore to urban-inshore, and between winter and summer. We report that ...

The theme of this report is the regional socio-economic consequences of an extensive oil and gas development in the Barents Sea. The regional focus area includes Finnmark County and Murmansk Oblast. The introductory chapter explains the purpose of the study and the way the work has been done. The next two chapters provide a detailed account of the region and its basic characteristics. The general ...

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 ...

Heart and skeletal muscle inflammation (HSMI), caused by infection with Piscine orthoreovirus-1 (PRV-1), is a common disease in farmed Atlantic salmon (Salmo salar). Both an inactivated whole virus vaccine and a DNA vaccine have previously been tested experimentally against HSMI and demonstrated to give partial but not full protection. To understand the mechanisms involved in protection against HSMI ...
