Mutual impact of wild and cultured Atlantic salmon in Norway
(ICES CM Documents;1988/Mini:5, Working paper, 1988)The development and current status of the fish farming industry, enhancernent and sea ranching of salmon in Norway are briefly described, and an account is given of the natural salmon river populations in different parts ... -
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 ... -

Norwegian blue whiting investigation in April/May 1980.
(ICES CM Documents;1980/H:61, Working paper, 1980)An acoustic survey on the blue whiting stock was conducted from 8 April to 14 May 1980. The area west of the British Isles was covered twice and then the area around the Farces and further up to Shetland and the Norwegian ... -
The Norwegian industrial trawl fishery in the North Sea.
(ICES CM Documents;1978/G:15, Working paper, 1978)Linear programming is used to demonstrate a way to maximise the total catch in a mixed fishery. Constraints are set by quotas, as well as requirements that the total catch should not be too unevenly distributed between ... -

On fecundity of North Sea mackerel (Scomber scombrus)
(ICES CM Documents;1980/H:47, Working paper, 1980)This paper presents a preliminary analysis of the fecundity-length relationship of the North Sea mackerel. The relationship was compared to that of the Western mackerel stock (LOCKWOOD,1978) by an analysis of covariance ... -
On the formation of the first winter zone in blue whiting otoliths.
(ICES CM Documents;1979/H:7, Working paper, 1979)Otolithes of juvenile blue whiting when recruiting to the industrial fishery in the Norwegian Deep in early autumn (August-October 1970-72) could be divided into two groups, without or with a very insignificant hyaline ... -
Organic waste and antibiotics from aquaculture
(ICES CM Documents;1988/F:14, Working paper, 1988)During the past year three joint projects have been conducted concerning the fate of organic waste and antibiotics from various Norwegian fish farms. The projects are investigating the following topics: - decomposition ... -

Physiological changes in blood and seminal plasma during the spawning period of maturing rainbow trout held under different temperature and salinity regimes, and the effect on survival of the broodstock and the eyed eggs
(ICES CM Documents;1988/F:3, Working paper, 1988)Maturing rainbow trouts reared in sea cages were transferred to tanks and kept under nine different temperature and salinity regimes. Blood and seminal fluids were regularly sampled from the fish, and different organic ... -
Phytoplankton depletion by mussel aquaculture: high resolution mapping, ecosystem modeling and potential indicators of ecological carrying capacity
(ICES CM documents;2008/ H:12, Working paper, 2008)Mussels held in suspended culture have an exceptional capacity to filter the water column and reduce suspended particle concentrations. However, seston depletion is only of concern if the phytoplankton are cleared faster ... -
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 ... -
