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. ... -

(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 ... -
