Hatchery selection may depress the number of motile sperm but intensify selection for their swimming velocity in the Arctic charr
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)The ability of captive breeding programs to maintain genetic diversity and fitness has often been questioned. Recent studies suggest that fitness loss can be extremely rapid in various traits, but it is poorly known how captive breeding affects sperm quality and thus male fertility. We studied the potential effects of hatchery-induced selection on traits indicative of semen quality, in four generations ... -
Haul-out behaviour of Arctic ringed seals (Pusa hispida): inter-annual patterns and impacts of current environmental change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-27)Hauling out onto a solid substrate is an integral part of most pinnipeds’ activity budgets. Ringed seals (<i>Pusa hispida</i>) are an Arctic species that hauls out on sea ice routinely throughout the year. In 2006, a sudden change in the sea-ice regime occurred in Svalbard (Norway). Amongst other changes, the amount of land-fast ice declined sharply. This study examined the intra- and inter-annual ... -

Hav, fisk og ressursforvaltning i nordområdene
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-08)Mesteparten av norske havområder ligger nord for polarsirkelen og er åsted for noen av verdens rikeste fiskerier. De største fiskebestandene er delt med andre land, og internasjonalt samarbeid om ressursforvaltningen er derfor en viktig dimensjon ved nordområdepolitikken. Slikt samarbeid er basert på globale normer om hvordan levende marine ressurser skal forvaltes og deles og foregår på en rekke ... -
Havbruksnæringen og koronapandemien
(Master thesis; Mastergradsoppgave, 2022-05-16)Norsk havbruksnæring har siden starten på 1970-tallet hatt en kontinuerlig vekst og utvikling. Norsk atlantisk laks har en stor etterspørsel i det globale markedet. I dag er næringen Norges nest største eksportnæring.
