This study focused on two important issues on the Barents Sea bottom trawl fishery for Northeast Arctic cod (Gadus morhua L.); catch quality (i.e., the quality of the fish caught) and size selectivity. The high abundance of cod encountered in recent years in the Barents Sea, leading to subsequent large annual quotas, has led to increased interest in improving the quality of fish caught by trawls. ...

Scholarly publishing is the vessel for the dissemination of research articles. Contemporary scholarly publishing is achieved by two main models, open access (OA) and non-open access (non-OA). OA refers to articles that are available at no cost to the end-user; however, authors may incur a fee for accepted manuscripts. Non-OA articles are available at a cost, either via subscriptions or via individual ...

Marine spatial planning (MSP) is rapidly becoming the dominant approach to managing human interactions with marine environments. As this happens we are making more attempts to understand how it operates and how it might be improved. This study focuses on the governance of complex marine environments through MSP in Scotland. It focuses specifically on transparency and participation in MSP, and the ...

Atlantic salmon is experiencing population declines throughout most parts of its distribution range, with changes in the marine environment considered important contributors to the overall decline. Most of the current knowledge about Atlantic salmon’s ocean distribution originates from mark-recapture and genetic studies associated with high-sea fisheries and sampling surveys, and therefore, little ...

Central control mechanisms of food intake vary between different fish species. Few studies have investigated the role of central appetite regulators in fish species that show natural seasonal variations in food intake. Yet, seasonal fishes are particularly interesting because their potential seasonally sliding set-points in appetite and energy homeostasis may reveal new information about the ...

Worldwide there have been many attempts to implement community-based conservation to gain a more inclusive protection of biological diversity. Reducing human pressures on ecosystems is necessary for favorable ecological outcomes of protected areas, but conservation initiatives that rely on strict enforcement without local support are vulnerable to rule-violations, public protests and a reduced ...

Purpose: In light of the increasing numbers of overweight children observed today who follow inadequate diets, this dissertation mainly explored how children are socialised as food consumers. An additional purpose was to explore the advantages of using participatory photo interviews while researching children’s attitudes and behavioural patterns with respect to two food contexts, namely, lunch in ...

Price and quantity numbers, which we are observing in a market place, occur because of an interaction between supply and demand. An understanding of what drives supply and demand is therefore important in order to understand the market in itself. This dissertation focuses on determining the impact of exogenous factors on salmon biomass growth and how producers respond to price changes. Furthermore, ...

The Arctic is currently in a rapid state of change, with temperature increases in this region being three times the rate of the global average and sea-ice extent declining rapidly. In 2006, a sudden shift in the sea-ice regime in Svalbard, Norway, occurred with the altered sea-ice conditions persisting to the present day. In order to study the impacts of the environmental changes occurring in the ...

Many benthic marine organisms produce pelagic larvae, meroplankton, which spend from hours to months in the pelagic. During this time, they form an important part of the pelagic community. Few studies have focused on the year round dynamics of meroplankton, thus many aspects of meroplankton dynamics remains unknown at high-latitudes. In the 1960s the red king crab was intentionally introduced into ...
