The Norwegian industrial trawl fishery in the North Sea : a study on how the total catch in 1975 could have been increased without exceeding the quotas of cod, haddock and whiting
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1979)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 ... -

Norwegian Tagging of Harp Seals and Hooded Seals in north atlantic waters
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1964)The tail tag and the tagging method are described. A total of 711 harp and hooded seals have been tagged in the years 1951-1963. Excepting experimental tagging of one adult and 18 immature harp seals in the Barents Sea ... -
The Norwegian-Icelandic Herring Tagging Experiments - Report No. 1
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1950)In the preceding chapters it is demonstrated that the Norwegian-Icelandic herring tagging experiments have met with success. When properly handled the herring is capable of withstanding the shock of tagging, and this ... -
A Note on the Effect of Electric Fields on Gadus virens
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1959)To test electrotaxis earlier experiments have been performed in relatively small tanks. It was felt, therefore that the arrangement with a comparatively big tank would give greater allowance for a more varied behaviour ... -

Notes on the energy metabolism of the cod (Gadus callarias L.) and the coalfish (Gadus virens L.) in relation to body size
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1957)The present work on the oxygen consumption in the cod and the coalfish shows that there is a connection between the body size and the acclimation time required for reaching a "normal" level of metabolism after being ... -
