Parental migration, climate and thermal exposure of larvae: spawning in southern regions gives Northeast Arctic cod a warm start
(Journal article; Peer reviewed, 2011-10-20)Temporal variability in environmental conditions met by early life stages is considered a key driver of fluctuations in recruitment and abundance of fish stocks. Variability in spawning grounds selected by the parental ... -

pH adjustment of acid water at Matre Aquaculture Station: Experiences with previous and existing methods
(ICES CM Documents;1984/F:28, Working paper, 1984)The water from Matre River is characterized as very soft, with a total hardness of 1. 5 - 2. 5 mg Ca0/1 and a very low buffer capacity. Acid precipitation results in low pH, values below 5. 0 are recorded every year. ... -
Phylogenetic and morphological characterisation of the green algae infesting blue mussel Mytilus edulis in the North and South Atlantic oceans
(Journal article; Peer reviewed, 2008-09-24)Blue mussels Mytilus edulis with shell deformations and green pustules containing parasitic algae were collected at 3 coastal sites (Burøy, Norway; Bockholm, Denmark; Goose Green, Falkland Islands). A comparative study, ... -
Picoeucaryot alga infecting blue mussel Mytilus edulis in southern Norway
(Journal article; Peer reviewed, 2005-01-25)During summer 2001, blue mussels Mytilus edulis with abnormal shell growth were collected near Kragerø, southern Norway. The mussels had green spots in their mantle tissues, mainly posteriorly and ventrally, and in the ... -
Piscivorous fish patrol krill swarms
(Journal article; Peer reviewed, 2005-09-01)Dense swarms of the krill Meganyctiphanes norvegica in the Norwegian Sea were patrolled by large, piscivorous fish, which apparently use the krill swarms as feeding grounds in their hunt for planktivores. For the krill, ... -

Plankton community structure and fish spawning area indicators in the Bay of Biscay, using Laser Optical Plankton Counter
(ICES CM Documents;2005/P:13, Working paper, 2005)In the Bay of Biscay, regular fisheries acoustic cruises are conducted to assess small pelagic fish stocks. Within the frame of the Bay of Biscay integrated project, measurements of additional biotic and abiotic variables ... -

Population dynamics of salmon lice Lepeophtheirus salmonis on Atlantic salmon and sea trout
(Journal article; Peer reviewed, 2005-04-13)The salmon louse Lepeophtheirus salmonis is a common ectoparasite of both farmed and wild salmonids in the marine environment, and can have a significant negative effect on the survival and growth of its host. To facilitate ... -
Population genetic structure of the parasitic copepod Lepeophtheirus salmonis throughout the Atlantic
(Journal article; Peer reviewed, 2011-04-12)The parasitic copepod Lepeophtheirus salmonis is responsible for huge economic losses in the salmonid aquaculture industry, and has been linked with declines of wild salmonid populations. In order to elucidate population ... -
Potential implications on the pelagic fish and zooplankton community of artificially induced deep-water releases of oil and gas during DeepSpill_2000 – an innovative acoustic approach.
(Fisken og havet;14-2001, Research report, 2001-12-15)During the DeepSpill_2000 field experiment (Johansen et al., 2001) oil and gas were artificially released on several occasions from a water depth of 844 meters at the Helland-Hansen site in the Norwegian sea. Prior to and ... -
Predation of oyster larvae by Aurelia aurita in a Norwegian oyster pond
(ICES CM Documents;1986/F:21, Working paper, 1986)In the norwegian oyster spatting ponds several factors may influence the spat production. During a basic, general study in a pond in 1983-84, Aurelia aurita was demonstrated to be a heavy predator on pelagic oyster ... -
