The Nordmøre grid is the principle bycatch mitigation device in many shrimp trawl fisheries. However, in several of these fisheries, bycatch is a problem because small sized fish can pass through the grid and enter the codend together with the targeted shrimp. One such fishery is the Northeast Atlantic deep-water shrimp (<i>Pandalus borealis</i>) fishery, where the use of a Nordmøre grid is mandatory. ...

This paper explores the ecosystem services provided by anadromous brown trout (often termed sea trout) populations in Norway. Sea trout is an important species in both freshwater and marine ecosystems and provides important demand-driven ecological provisioning and socio-cultural services. While the sea trout once provided an important provisioning service through a professional fishery and subsistence ...

In the reformed technical measures regulation, the European Union proposed a greater involvement of the fishing industry in the different managerial aspects of fisheries. However, having the industry as a main actor in gear development presents a new suite of challenges. The industry, while addressing an issue in the fishery, can modify several aspects of a fishing gear simultaneously, without ...

Atlantic salmon (Salmo salar L.) aquaculture is a relatively new industry in Norway, dating back to the 1960s. It has since then developed in to a profitable industry. Continuous improvement of hygiene control, knowledge of fish nutrition and health has been important for this development. Fish nutrition is a research field that has been increasingly focused on partly due to more use of plant raw ...

It has been reported that the green sea urchin, Strongylocentrotus droebachiensis, can be affected by symptoms that is associated with the disease called “bald sea urchin disease”. However, no pathogen for sea urchins are known in the literature, but a working hypothesis claims that species of the Vibrio splendidus clade can be associated with symptoms characterized as bald sea urchin disease in S. ...

The size selectivity and usability of two diamond mesh codends, a traditional two-panel codend versus an experimental four-panel ultra-cross knotless mesh codend, were compared using the covered codend method in the Iceland redfish (<i>Sebastes norvegicus and S. viviparous</i>) fishery. Results showed that there was no significant difference in size selectivity between the codends at lengths greater ...

Three wild-caught female harp seals (Pagophilus groenlandicus) from the Greenland Sea stock were brought into temporary captivity in connection with a controlled validation study on energetics. The two pups and one adult were kept in two indoor and outdoor experimental facilities approved by the Norwegian Animal Research Authority. They were trained daily using operant conditioning to participate ...

The industrialization of fisheries and the growth of a capitalist sector within fisheries have received considerable scholarly attention. For the most part, scholars have emphasized how capitalism has led to privatization of the commons, forced small-scale resource users into wage labor, and marginalized the sector. This analysis does not, however, explain the continued presence of such a vibrant ...

The main challenge for the European seafood industry is to ensure sustainable production volume while adapting to climate warming. Marine fisheries mainly target 41 species which account for 80% of the seafood production in Europe. The remaining 20% comes from marine and freshwater aquaculture, which harvest mainly 5 and 11 species, respectively. European seafood production volume (2004–2014) recorded ...

The purpose of this study was to investigate the extent of external damage (gear marks, pressure injuries, ecchymosis and skin abrasion) present on trawl-caught cod (Gadus morhua) and to examine whether the extent of damage could be reduced by introducing changes in the gear. We tested whether changing the 2-panel knotted codend used by the Norwegian trawler fleet operating in the Barents Sea today ...
