Etter hvert som havbruksnæringen har vokst, har det med dagens driftsformer dukket opp problemer med spredning av lakselus, rømming av oppdrettslaks og utslipp av organiske materialer og avlusningsmidler. I tillegg, en begrensing i arealer som kan brukes til oppdrett av laks. Denne oppgaven er en dokument analyse hvor man ved hjelp av offentlige dokumenter, avisartikler og vitenskapelige artikler ...

Forskning knyttet til ledelse og innvirkning den har på organisasjoner gjennomføres nesten daglig verden over, og er blitt en tematikk som rettes mye fokus både i arbeidslivet og i akademia. Forskning knyttet direkte opp til ledelse i oppdrettsnæringen virker derimot å være mer eller mindre fraværende. Dette på tross av at det er en ansvarstynget rolle, innen et næringssegment som for fremtiden spås ...

Med økende havtemperaturer er det forventet at varmekjære arter vil vandre nordover og inn i Barentshavet, og at torsken i dette området vil vandre lengre nord og øst. Det er også en forventning at torskebiomassen vil øke i Barentshavet på grunn av økt primærproduksjon. En sammenligning av biomassene til torsk og hyse i seks ulike økosystemer med ulike temperaturer viser at Færøyene danner et skille. ...

<ol> <li>Two common <i>Dibothriocephalus</i> (formerly <i>Diphyllobothrium</i>) tapeworm species were significantly reduced by experimental culling of their fish host Arctic charr (<i>Salvelinus alpinus</i>) in a subarctic lake.</li><p> <p><li>Between 1984 and 1991, funnel traps were used to cull ~35 metric tons of Arctic charr, reducing charr density by ~80%. As charr densities decreased, ...

It is well known that grammatical gender systems may change historically. Previous research has documented loss of the feminine gender in several Norwegian dialects, including those spoken in Oslo and Tromsø (Lødrup in Maal og Minne 2:120–136, 2011; Rodina and Westergaard in J Ger Linguist 27(2):145–187 2015). In these dialects, the change is characterized by replacement of the feminine indefinite ...

<i>Background</i> - Fecal calprotectin is widely used to monitor disease activity in patients with inflammatory bowel disease. Multiple commercial kits exist, however, since the analyses are not standardized, these kits cannot be used interchangeably. We aimed to perform a technical evaluation of two kits (Calpro from Calprolab, Norway and Calprest from Eurospital, Italy) and perform a tuning for ...

<i>Background</i>: Diabetes mellitus (DM) is a metabolic disorder that causes abnormal blood glucose (BG) regulation that might result in short and long-term health complications and even death if not properly managed. Currently, there is no cure for diabetes. However, self-management of the disease, especially keeping BG in the recommended range, is central to the treatment. This includes actively ...

We analyze the possible impacts of pollution on a fishery by means of a dynamical systems theory approach. The proposed model presupposes that activities stimulating economic growth also cause higher emissions that remediate or accumulate in the oceans. The density of pollution is assumed to affect the fishery negatively by reducing biological growth potential and decreasing marginal willingness to ...

Phonological variation can be defined as describing “a situation in which a single morpheme can be realized in more than one phonetic form in a single environment” (Coetzee & Pater, 2011, p. 401). In the latter decades, research on this integral part of grammar has become increasingly important, resulting not only in a growing literature on the topic, but also in large datasets on which hypotheses ...
