Genetic analyses of cod in northern norway. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)Several polymorphic proteins have been used in studies of cod stock structure in northern Norway. Samples of Arctic cod spawning in Lofoten in the spring of 1981 were analysed for enzyme polymorphism by starch gel ... -
Growth of cod in relation to fish size and ration level. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)This study presents the main results of a series of growth experiments on cod with particular reference to ration size, size of the fish and growth and feeding in the spawning season. The experiments were started in ... -
Growth, energy consumption and prey density requirements in first feeding larvae of cod (Gadus morhua L.). In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)Growth, oxygen uptake, swimming activity, feeding ability and energy content were investigated in cod larvae from several groups under different experimental conditions. At yolk absorption the larvae consumed 0.090-0.120 ... -
Growth, mortality and feeding of cod (Gadus morhua L.) larvae in enclosed water columns and in laboratory tanks. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)In April 1982 cod larvae were reared in four 30 l laboratory tanks and in two 300,000 l columnar plastic enclosures for 3-4 weeks from hatching. North Sea oil "production water" was added to one of the enclosures ... -
The haemoglobin polymorphism in Atlantic cod (Gadus morhua L.); genotypic differences in somatic growth and in maturing age in natural populations. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)The two common alleles at the polymorphic haemoglobin locus HbI (Sick, 1961) in the Atlantic cod (Gadus morhua L.) code for proteins whose functional properties are differentially influenced by environmental ... -

Importance of genetic variation in the propagation of cod. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)During the last decade the existence of genetic diversity within species and populations has been generally accepted. The complex structure of populations as well as the variations within populations is believed to be ... -
Inferences regarding predation on the early life stages of cod and other fishes. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)Little information exists on the predation on the early life stages of marine fish in general and even less on cod. Thus the approach used in this review was to infer the predatory processes that may be significant in ... -
Ingestion of bacteria by cod (Gadus morhua L.) larvae. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)The uptake of Rhodamine-labelled bacteria by cod larvae was demonstrated using a fluorescent microscopy technique, which allowed a quick estimate of bacterial uptake and gut clearance. Live or heat-killed bacteria, ... -

The intensive tearing of juvenile cod, Gadus morhua L. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)Cod were reared in the laboratory from the egg to marketable size using cultured live foods for the early stages and then artificial diets. Survival to metamorphosis was about 10%; subsequent mortalities were negligible. The ... -
Kan bruken av flerbestandsmodellen Systmod endre vårt syn på forvaltningen av torskebestanden i Barentshavet?
(Conference object, 2008-11-06)Systmod er en konseptuell simuleringsmodell for biomasseproduksjonen i bestandene av lodde, sild og torsk i Barentshavet. Hver bestand er modellert med enbestandsmodeller, hvor bestandsinteraksjonene er klimarelatert og ... -

Large-scale rearing of cod fry on the natural food production in an enclosed pond. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)For four years (1980-1983) populations of 5 day old cod larvae have been transferred to a dammed seawater pond (60 000 m^3 ). The water volume had been treated with rotenone in advance, and the larvae were released ... -
Larval fish trophodynamic studies on Georges Bank: sampling strategy and initial results. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)A sampling strategy is outlined to serve as a framework for determining the fine- to micro-scale vertical disribution or fish larvae and their prey on Georges Bank in a single vessel, interdisciplinary mode of operation. ... -
