Fluctuating sea-cage environments modify the effects of stocking densities on production and welfare parameters of Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2011-05-21)Stocking densities are commonly used to set limits for the production of fish in sea-cages, yet limited information exists to assess how environmental fluctuations modify the effects of stocking densities on the production ... -

(Rapport fra Havforskningen;28-2016, Working paper, 2016-06-30)Havforskningsinstituttet (HI) har på oppdrag fra Mattilsynet (MT) og Nærings- og fiskeridepartementet (NFD) ansvaret for å koordinere overvåkning, forskning og rådgivning vedrørende lakselusinfestasjon på vill laksefisk ... -
Gastric evacuation rate in mackerel (Scomber scombrus L.)
(ICES CM documents, Working paper, 1983)About 1500 mackerel, 25-45 cm in Length, were kept in a net for l0 days. In two experiments the fish were £ed frozen euphausiids -ad. libiturn, and the wet weight of the stomach content determined every second hour for ... -
Genetic comparison of salmon (Salmo salar L.) from the White Sea and the Atlantic ocean
(ICES CM Documents;1996/M:13, Working paper, 1996)Samples of salmon (Salmo salar) from River Kachkovka and R. Nilma in northem Russia were analysed by starch gel electrophoresis and compared to three Norwegian stocks, R. Neiden in northern Norway and R. Øyre and R. Hop ... -
Genetic mixed-stock analysis of Atlantic herring populations in a mixed feeding area
(Journal article; Peer reviewed, 2011-12-05)Determining spatio-temporal distributions of fish populations is of interest to marine ecology, in general, and to fisheries science in particular. Genetic mixed-stock analysis is routinely applied in several anadromous ... -
Genetic studies on released and recaptured cod in a fjord system
(ICES CM Documents;1992/G:65, Working paper, 1992)The study reported here is part of a more extensive investigation on the effects of mass rearing and release of 0-group cod in fjords and coastal areas in Norway. Each year since 1987 pond produced cod have been liberated ... -
Genomic Characterization and Phylogenetic Position of Two New Species in Rhabdoviridae Infecting the Parasitic Copepod, Salmon Louse (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2014-11-17)Several new viruses have emerged during farming of salmonids in the North Atlantic causing large losses to the industry. Still the blood feeding copepod parasite, Lepeophtheirus salmonis, remains the major challenge for ... -
Genotype distributions of cod from the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 1992-02-20)The genotype distributions for cod, Gadus morhua L., from the southeastern coast of Norway are studied as part of a more extensive study on cod enhancement and the possible effects of mass liberation of 0-group cod on ... -
Getting fat in a hurry: food consumption during the feeding migration of NSS herring
(ICES CM Documents;2004/K:64, Working paper, 2004)The Norwegian spring-spawning (NSS) herring Clupea harengus inhabits a seasonal environment where food is abundant only during a short period of the year. During that period NSS herring store energy for metabolic ... -
Group Behavioural Responses of Atlantic Salmon (Salmo salar L.) to Light, Infrasound and Sound Stimuli
(Journal article; Peer reviewed, 2013-05-17)Understanding species-specific flight behaviours is essential in developing methods of guiding fish spatially, and requires knowledge on how groups of fish respond to aversive stimuli. By harnessing their natural behaviours, ... -
Growth and survival studies of halibut (Hippoglossus hippoglossus L.) from hatching to beyond metamorphosis carried out in mesocosms
(ICES CM Documents;1986/F:16, Working paper, 1986)To each of five floating plastic bags 1500 halibut larvae were transferred from the hatchery one day after hatching. The plastic bags had a volume of 11.5 m3, a total depth of 5.5 m and they were moored to floating ... -
Growth in the Norwegian spring-spawning herring for the year-classes 1950 -1960 and 1973 -1983
(ICES CM Documents;1988/H:35, Working paper, 1988)Two periods with great differences in year-class abundance and recruitment where chosen for growth studies. In the first period the mean year-class strength at 3 years was 6 790 x 10[6] individuals while in the second ... -
Growth of capelin in relation to zooplankton biomass in the Barents Sea
(ICES CM Documents;1995/P:5, Working paper, 1995)Growth of capelin in the Barents Sea stock has been found to vary considerably both between years and between different parts of the distribution area. The aim of this paper is to compare such growth variations with ... -
