Nasjonalt tilsynsprogram for produksjon av skjell og andre bløtdyr – prøver analysert i 2017 for kjemiske forurensende stoffer og mikroorganismer
(Rapport fra havforskningen;2018 - 46, Research report, 2018)I den mikrobiologiske delen av tilsynsprogrammet for skjell, tok Mattilsynet i 2017 ut i alt 247 prøver fordelt gjennom året. Av disse var 159 blåskjell (Mytilus edulis), 29 kamskjell (Pecten maximus), 18 østers (Ostrea ... -

Natural and anthropogenic drivers of escaped farmed salmon occurrence and introgression into wild Norwegian Atlantic salmon populations
(Peer reviewed; Journal article, 2022)Marine aquaculture of Atlantic salmon (Salmo salar) is a relatively new industry where breeding programs have led to rapid genetic change in the captive populations that were built up alongside conspecific wild individuals. ... -
Natural and anthropogenic factors influencing abundance of the benthic macrofauna along the shelf and slope of the Gulf of Guinea, a large marine ecosystem off West Africa
(Peer reviewed; Journal article, 2020)The West African continental margin belongs to the least known areas in terms of the ecology of benthic ecosystems. At the same time, this region is influenced by various threats associated with human activities, including ... -
Natural and cultivated zooplankton as food for halibut (Hippoglossus hippoglossus) larvae
(ICES CM Documents;1987/F:17, Working paper, 1987)Natural zooplankton were pumped into a collector and size-fractionated. The zooplankton smaller than 350 ym were fed on a diatom dominated algal suspension cultured in 3 m deep out-door plastic bags. Halibut larvae ... -
Natural fish behaviour and catchability of groundfish
(ICES CM Documents;1994/G:14, Working paper, 1994)Imprecision in estimates of abundance and population parameters obtained from trawl surveys could be reduced if the sources of variability were understood and properly described. Fish behaviour in relation to sampling ... -
Natural mortality estimations for beaked redfish (Sebastes mentella) – A long-lived ovoviviparous species of the Northeast Arctic
(Peer reviewed; Journal article, 2023)Beaked redfish (Sebastes mentella) is one of the few commercially important fish species producing living offspring. Like many other deep-water fishes, it is slow growing, late maturing and long-lived, getting as old as ... -
Nature Index Costa Rica. An IPBES pilot project.
(NINA rapport;1112, Research report, 2014)KORT OM NI-CR Pilotprosjektet “Nature Index Costa Rica” (NI-CR) har tatt mål av seg å demonstrere kapasi-tetsutvikling i tråd med målsettingene til Naturpanelet (IPBES). Gjennom det ett-årige pilot-prosjektet samarbeidet ... -

NEA saithe XSA runs with different survey tuning series
(Working paper, 2010-02)New tuning series from a combined and improved survey gives lower and more stable S. E. Log q residuals than the tuning series presently used. However, the retrospective trend is still poor and the estimates of F and SSB ... -

Near-bottom sampling with bottom and pelagic trawls
(ICES CM Documents;1987/B:15, Working paper, 1987)The Institute of Marine Research, Bergen, has carried out combined bottom trawl and acoustic surveys for cod and haddock in the Barents Sea - Svalbard area since 1981. These investigations have demonstrated clearly that ... -
Near-Surface Stratification Due to Ice Melt Biases Arctic Air-Sea CO2 Flux Estimates
(Peer reviewed; Journal article, 2021)Air-sea carbon dioxide (CO2) flux is generally estimated by the bulk method using upper ocean CO2 fugacity measurements. In the summertime Arctic, sea-ice melt results in stratification within the upper ocean (top ∼10 m), ...
