Ny teknologi for overvåking av oppdrettsmiljø og fiskevelferd i oppdrettsmerder. Sluttrapport for FHF prosjekt 900085
(Nofima rapportserie, Research report, 2010)Det er kjent at oppdrettsfisk som trives er god butikk, da de vil vokse fortere, være mindre utsatt for sykdom og gi bedre produktkvalitet. Samtidig stiller markedene økende krav til etisk produksjon, inklusiv dokumentasjon ... -
Nye omega-3-kilder i fôr til laks
(Nofima rapportserie, Research report, 2019)Dette prosjektet har hatt som hovedmål å skaffe kunnskap om utnyttelse av to nye DHA-kilder i fôr til laks, henholdsvis olje fra genmodifisert raps og mikroalgen Schizochytrium sp. Prosjektet har hatt et spesielt fokus på ... -
Observational insights into chlorophyll distributions of subtropical South Indian Ocean eddies

Observations of cod reaction to trawling noise
(Working paper, 1988-04)Observations made from a stationary echo sounder, passed by a trawling vessel, clearly demonstrate the flight reaction of cod as a response to the noise from the vessel. Horizontal dispersal and downward swimming has been ... -
Observing individual fish behavior in fish aggregations: Tracking in dense fish aggregations using a split-beam echosounder
(Journal article; Peer reviewed, 2007)Acoustic instruments are important tools for observing the behavior of aquatic organisms. This paper presents a simple but efficient method for improving the tracking of closely spaced targets using a split-beam echosounder. ... -
Observing the behavioral response of herring exposed to mid-frequency sonar signals. (A)
(Conference object, 2010-03)There is general concern on how mid-frequency military sonars might affect aquatic animals. Approaches used to investigate possible effects on Norwegian spring spawning herring (Clupea harengus) are presented. Experiments ... -
Occurrence and diet of killer whales in northern Norway: seasonal patterns relative to the distribution and abundance of Norwegian spring-spawning herring
(Journal article; Peer reviewed, 1996)Our objectives were to investigate the seasonal occurrence of photoidentified killer whale pods in relation to the distribution of Norwegian spring-spawning herring and whether or not pod-specific differences in the ... -
Occurrence of larval ascaridoid nematodes in the Argentinean short-finned squid Illex argentinus from the Southwest Atlantic Ocean (off Falkland Islands)
(Journal article; Peer reviewed, 2019)The Argentinean short-finned squid (Illex argentinus) is an oceanic, neritic species widely distributed off the east coast of South America, representing the most abundant commercially exploited squid species in these ... -
Occurrence of salmonid alphavirus and piscine orthoreovirus-1 infections in migrating salmon (Salmo salar L.) post-smolt in western Norway
(Peer reviewed; Journal article, 2023)Viral diseases are a serious problem in Atlantic salmon (Salmo salar L.) farming in Norway, often leading to reduced fish welfare and increased mortality. Disease outbreaks in salmon farms may lead to spread of viruses to ... -
Ocean acidification and desalination: climate-driven change in a Baltic Sea summer microplanktonic community
(Journal article; Peer reviewed, 2018)Helcom scenario modelling suggests that the Baltic Sea, one of the largest brackish-water bodies in the world, could expect increased precipitation (decreased salinity) and increased concentration of atmospheric CO2 over ... -
Ocean Acidification Effects on Atlantic Cod Larval Survival and Recruitment to the Fished Population
(Journal article; Peer reviewed, 2016-08-23)How fisheries will be impacted by climate change is far from understood. While some fish populations may be able to escape global warming via range shifts, they cannot escape ocean acidification (OA), an inevitable consequence ... -
Ocean acidification state in western Antarctic surface waters: controls and interannual variability
(Journal article; Peer reviewed, 2014-01-06)During four austral summers (December to January) from 2006 to 2010, we investigated the surface-water carbonate system and its controls in the western Antarctic Ocean. Measurements of total alkalinity (AT), pH and total ... -
Ocean acidification state variability of the Atlantic Arctic Ocean around northern Svalbard
(Peer reviewed; Journal article, 2021)The Svalbard shelf and Atlantic Arctic Ocean are a transition zone between northward flowing Atlantic Water and ice-covered waters of the Arctic. Effects of regional ocean warming, sea ice loss and greater influence of ... -
Ocean Acoustic Waveguide Remote Sensing (OAWRS) of marine ecosystems
(Journal article; Peer reviewed, 2009-12-03)Ocean Acoustic Waveguide Remote Sensing (OAWRS) has recently been shown to be capable of instantaneously imaging and continuously monitoring fish populations over continental shelf-scale areas, covering thousands of km2. ... -

Ocean biogeochemistry in the Norwegian Earth System Model version 2 (NorESM2)
(Peer reviewed; Journal article, 2020)The ocean carbon cycle is a key player in the climate system through its role in regulating the atmospheric carbon dioxide concentration and other processes that alter the Earth's radiative balance. In the second version ... -
Ocean current connectivity propelling the secondary spread of a marine invasive comb jelly across western Eurasia
(Journal article; Peer reviewed, 2018)Invasive species are of increasing global concern. Nevertheless, the mechanisms driving further distribution after the initial establishment of non‐native species remain largely unresolved, especially in marine systems. ...
