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 distribution and ecology of Myxine glutinosa L.
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1969)The distribution and ecology of the hagfish, Myxine glutinosa, in the Bergen area is discussed, especially its depth occurrence. The ascent of the species to lesser depths in the inner fjords is seen in relation to ... -
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 ... -

Observations on the embryonic development of capelin (Mallotus villosus MÜLLER) from the Barent Sea
(Fiskeridirektoratets skrifter, serie havundersøkelser;vol 18, no. 2, Research report, 1986)The embryonic development of the Barents Sea capelin is described, with emphasis of characteristic features which can be applied in the ageing of eggs. The development is described for three different temperatures observed ... -
