A case study on the distribution of cod larvae and availability of prey organisms in relation to physical processes in Lofoten. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
Ellertsen, Bjørnar; Fossum, Petter; Solemdal, Per; Sundby, Svein; Tilseth, Snorre (Flødevigen rapportserie, Conference object, 1984)The distribution of cod larvae and copepod nauplii off the Lofoten islands was studied in the years 1979-82. The highest concentrations of cod larvae and copepod nauplii were found in the Austnesfjord, Hølla-Henningsvær ... -
Field studies on the behaviour of whiting (Gadus merlangus L.) towards baited hooks
Fernö, Anders; Solemdal, Per; Tilseth, Snorre (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1986)The responses of whiting to a test line with baited hooks were studied during three cruises in the Trondheimsfjord area in three seasons. The activity of the fish directed towards the baited hooks increased at sunrise ... -
Food consumption rate and gut evacuation processes of first feeding cod larvae In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
Tilseth, Snorre; Ellertsen, Bjørnar (Flødevigen rapportserie, Conference object, 1984)Laboratory experiments with cod larvae (Gadus morhua L.) during optimum feeding conditions showed that cod larvae were sporadic feeders rather than continuous feeders. Digestion rate of copepod nauplii was less than 30 ... -
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
Solberg, Tor Sverre; Tilseth, Snorre (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 ... -
Primary growth increments in otoliths of cod larvae (Gadus morhua L.) of the Arcto-Norwegian cod stock
Gjøsæter, Harald; Tilseth, Snorre (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1982)Primary growth increments have been detected in the otoliths of wild-caught, first-feeding cod larvae, living in a habitat where the light intensity is above the light threshold for visual feeding during 24 hours, and ... -
Some biological aspects of cod larvae (Gadus morhua L.)
Ellertsen, Bjørnar; Solemdal, Per; Strømme, Tore; Tilseth, Snorre; Westgård, Trond; Moksness, Erlend; Øiestad, Victor (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1980)The development of functional larval stages is described in relation to different yolk sac stages. Morphological and histological work has been done concomitantly with the observation on the larval feeding behaviour. ... -
