Betydning av tidspunkt og lengde av vintersignal i RAS for prestasjon i sjø ved utsett av stor smolt
(Research report; Forskningsrapport, 2023-12-01)Under kontrollerte forhold i kar var det en positiv effekt av et vintersignal kombinert med brakkvann i RAS på vekst etter overføring til sjøvann. Men et vintersignal ga også økt kjønnsmodning i hannfisk når fisken gikk lenge i RAS på kontinuerlig lys etter at vintersignalet var avsluttet. Kjønnsmodning ble redusert når fisken ble satt ut på lav sjøtemperatur. Resultatene fra utsett i sjømerder viste ... -

Biodiversity assessment of tropical shelf eukaryotic communities via pelagic eDNA metabarcoding
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-03)Our understanding of marine communities and their functions in an ecosystem relies on the ability to detect and monitor species distributions and abundances. Currently, the use of environmental DNA (eDNA) metabarcoding is increasingly being applied for the rapid assessment and monitoring of aquatic species. Most eDNA metabarcoding studies have either focussed on the simultaneous identification of a ... -
Bioeconomic Modelling of Coastal Cod and Kelp Forest Interactions: Co-benefits of Habitat Services, Fisheries and Carbon Sinks
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-26)Ecosystem-based fisheries management seeks to expand upon the traditional one-stock fisheries management measures by internalizing the effects of fishing on marine ecosystems, and accounting for biological interactions among marine resources. The fact that marine resources provide multiple, often competing benefits, makes the accomplishment of these ecosystem-based fisheries management objectives ... -
A bioeconomic MPA study based on cellular automata population growth and distribution
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)This paper investigates possible biological and economic effects of using marine sanctuaries as a management tool, employing cellular automata techniques to model biological growth and area distribution, assuming open access to the fish stock resources outside the protected area.
