Overvåking av Ytre Oslofjord 2014-2018. Tilførsler og undersøkelser i vannmassene i 2014. Fagrapport.
(NIVA-rapport;6818-2015, Research report, 2015-04-27)Overvåkingsprogrammet av vannmassene i Ytre Oslofjord skal fremskaffe informasjon om miljøtilstand og tilførsler til området, med fokus på næringssalter (eutrofi). Rapporten beskriver tilførsler for 2013 samt presenterer ... -
Overvåkning av havforsuring: prioriteringer og vurderinger
(Fisken og Havet;6-2014, Research report, 2014-10-14)Utslippene av karbondioksid til atmosfæren fører til reduksjon av pH i sjøvann, og denne prosessen har fått betegnelsen havforsuring. Havforskningsinstituttet har overvåket havforsuring siden 2010 i samarbeid med ... -

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 ... -

Pinging down the food web: multi-frequency acoustic discrimination of jellyfish and fish
(ICES CM Documents;2004/R:6, Working paper, 2004)Jellyfish are gaining increasing prominence in many pelagic marine ecosystems worldwide. It has been argued that jellyfish-dominated communities will be the end-point in ecosystems perturbed by high fishing effort, and ... -

Population genetic structure in a deepwater fish Coryphaenoides rupestris: patterns and processes
(Journal article; Peer reviewed, 2012-07-24)We observed significant genetic structure in a widely distributed North Atlantic demersal deepwater fish, the roundnose grenadier Coryphaenoides rupestris (Pisces: Macro - uridae). The overall estimate of genetic ... -
Population genetic structure of wrasses used as cleanerfish in Atlantic salmon farming in Norway
(ICES CM Documents;1993/G:30, Working paper, 1993)The increasing use of wrasses as cleaner fish in the salmon farming industry has created local fishery in many regions in Norway. In several cases, live fish have been transported between regions without knowledge of the ... -
Population structure of Ammodytes marinus in the Northeast Atlantic
(ICES CM Documents;1996/G:23, Working paper, 1996)Samples of the lesser sandeel species Ammodytes marinus Raitt were collected from Iceland, Denmark, Scotland, the Faeroe Islands and central and northern North Sea, and analysed for frequency distributions of genotypes ... -
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 ... -
Predation on the eggs of Norwegian spring-spawning herring at a spawning ground outside the westcoast of Norway in 1981
(ICES CM Documents;1985/H:55, Working paper, 1985)Predation on the eggs of demersal spawners has been reported several times, and findings of haddock feeding on capelin or herring eggs is a well known phenomenon. A spawning ground where spawning has been detected through ... -

Preliminary report from a study of species composition, size composition and distribution of the fish in a fjord of western Norway based on regularly conducted experimental fishing and catch statistics during one year
(ICES CM Documents;1986/G:70, Working paper, 1986)This paper is a contribution to the research program investigating the possibility of building up the local cod population in Masfjorden, a fjord in the westen Norway, by releasing large numbers of artificially produced ... -
Preliminary report from the sea-going workshop in Norway June 1993 on intercomparison and evaluation of methods for sampling and determination of zooplankton distribution and biomass
(ICES CM Documents;1993/L:45, Working paper, 1993)A sea-going workshop was arranged from 2 to 13 June 1993 in Storfjorden at Møre on the west coast of Norway. The workshop was a two-ship operation involving the Norwegian R/V "Johan Hjort" and the German R/V "A.V. Humboldt". ... -
