Shorthorn sculpin (<i>Myoxocephalus scorpius</i>) and large cod (300–400 g body weight) are important predators on newly settled 0-group cod (<i>Gadus morhua</i>) and saithe (<i>Pollachius virens</i>) in Porsangerfjorden in northern Norway. The Atlantic wolffish (<i>Anarhichas lupus</i>) used to be abundant but is now very rare in the fjord. Video recorded experiments showed that interactions between ...

Apex predators are characterized by high levels of biomagnifying organohalogenated contaminants (OHCs) which have been found to induce detrimental health effects in wildlife, such as immune system impairment. The leukocyte coping capacity (LCC) assay is a functional real-time measure of an innate immune response essential in pathogen resistance, known as the respiratory burst. The current study ...

Despite their contribution to employment, food security, poverty eradication, and community well-being, small-scale fisheries often find themselves in a disadvantageous position globally relative to large-scale fisheries and other industries competing for marine space, resources, and government attention. By and large, small-scale fisheries are marginalized in every sense of the word: culturally, ...

This case study, which uses interventionist action research methodology, first describes key elements of the online business model which was implemented at a business school in Arctic Norway. The aim of the business model intervention was to create a growth in student influx. Next, the study examines the actual impact of the intervention in terms of number of online applicants over the last decade. ...

Asia, particularly China, has become an attractive market that receives much attention in the Norwegian tourism industry. This raises relevant questions about the sustainability of the Chinese tourism boom. If the Norwegian tourism industry increasingly targets this rapidly growing market with larger investments, it should respond to the prospects of long-term growth. Such prospects hinge on the ...

Rapporten er en helhetlig vurdering av mulige grep innen arealforvaltning (arealplanlegging og lokalitetsforvaltning) av havbruk og marine områder for å gjøre areal tilgjengelig for vekst i havbruksnæringen, samtidig som også andre hensyn sikres, og at forvaltningen er tids- og kostnadseffektiv. Hvordan tilgangen på egnede arealer vil bli for næringen fram mot 2030 og videre, vil avhenge av flere ...

Half of the Arctic Ocean is deep sea (>1000 m), and this area is currently transitioning from being permanently ice-covered to being seasonally ice-free. Despite these drastic changes, it remains unclear how organisms are distributed in the deep Arctic basins, and particularly what feeds them. Here, we summarize data on auto- and heterotrophic organisms in the benthic, pelagic, and sympagic realm ...

External damages are indicators of the overall quality of fish and fish welfare. Haddock is an important commercial species widespread in the North Atlantic, but few studies related to quality have been carried out on this species. We studied the levels of external damages on haddock captured with a demersal trawl in the Northeast Atlantic. Further, we investigated to what extent the compulsory ...

Beta diversity is a key component of biodiversity with implications ranging from species dynamics to ecosystem functioning. However, β-diversity and its drivers have received little attention, especially for micro-eukaryotes which play key roles in soil functioning. We studied the diversity of soil micro-eukaryotes in a Swiss lowland floodplain using high-throughput Illumina sequencing of soil DNA. ...

Two adult specimens of the tropical to subtropical fish species <i>Diretmichthys parini</i> are reported from the North Sea and the northern Norwegian Sea, respectively. Both were accidentally caught as bycatch by commercial trawlers. Although not uncommon in Icelandic waters, it has not been documented from the Nordic Seas previously. In light of the major currents and water temperatures in the ...
