Om seiens ernæring
(Fisken og havet;1962 - Nr. 3, Journal article, 1962)l. Stomach contents of coalfish from Norwegian waters have been studied. 2. During the first months of the year the food of the 0-group coalfish proved to be planktonic animals; later a transition towards animals of a ... -

Omega 3-fettsyrer er viktig også for hummerhjernen : Omega-3 fatty acids are also important to the lobster ’s brain
(Havforskningsnytt, Working paper, 2009)Not only humans benefit from omega-3 fatty acids. Recent studies show that various types of fatty acids have different impacts on the formation of new brain cells in juvenile lobsters. -

Omplantningene av danske rødspetter (Pleuronectes platessa) til Oslofjorden og Skagerak 1934 og 1936
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1953)1. A short review is given on the transplantation of young plaice (Pleuronectes platessa Lin.) in Europe, from the first experiments in Denmark, about 1890, to the large transplantations in later years. From the North ... -
Omsetning av tilført partikulært organisk materiale i fjordbasseng med dype terskler
(Fisken og Havet;1-2015, Research report, 2015-03-26)Utviklingen i fiskeoppdrettsnæringen har ført til at økende antall anlegg blir lokalisert over dypere vann i store fjordområder. Dette medfører at de organiske partikulære utslippene fra fiskeoppdrett (fekalier og forspill) ... -
On acoustic identification, sizing and abundance estimation of fish
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1971)A method using the fish angle (i.e. the change in target strength with fish aspect) for identification purposes is described. Significant differences in fish angle between cod and coalfish have been observed at sea. The ... -
On Periodical Variations in the Yield of the Great Sea Fisheries and the Possibility of Establishing Yield Prognoses
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1942) -

On the growth of the cod and the formation of annual zones in the scales
(Report on Norwegian Fishery and Marine Investigations;vol 3 no 6, Research report, 1925) -
On the hydrographic fluctuations in the Labrador Sea during the years 1959-1969
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1974)During the years 1959 - 1969 Norwegian fishery research vessels collected oceanographic data off West Greenland, the observational work mainly being done in April. The data reveal gradually falling temperatures in the upper ... -

On the hydrography of the shelf waters off Møre and Helgeland
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)1. The distribution of temperatures and salinities off the west coast of Norway have been studied, based on observations from cruises in February 1956 and March 1968. 2. The main flow of Coast water follows the edge of ... -
On the life history of the spotted catfish (Anarhichas minor Olafsen)
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1963)Spotted catfish, Anarhichas minor Olafsen, were sampled from long line and trawl catches taken along the coast of Finnmark, near Bear Island and in the Barents Sea in 1953 and 1954. Age was determined from vertebraes. ... -
On the migrations of the cod in the Skagerak shown by tagging experiments in the period 1954-1965
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)1. A total of 1,244 cod was tagged from 1954 to 1965. The recapture percentage from the different tagging years varied between 24.9 aid 35.6 with a mean of 29.5 for the whole period. 2. No cod has been recaptured on the ... -
On the possibility of estimating year-class strength by measuring echo-abundance of 0-group fish
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1965)The possibility of estimating the distribution and abundance of 0-group fish by a combination of echo surveying and fishing experiments with pelagic trawl and purse seine is discussed. The existence of scattering layers, ... -
On the problem of the effect of fisheries on fish stocks
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)It is demonstrated by examples that morphological, physiological and behavioural features of fish developed evolutionary and normally of protective value are directly disadvantageous to the fish when subjected to intensive ...
