Individual growth rate and age at first sexual maturity in Atlantic salmon
Nævdal, Gunnar; Holm, Marianne; Lerøy, Rita; Møller, Dag (Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1978)Growth rates and possible connection between growth rate and age at maturation were studied on individually tagged salmon originating from different river populations. Great variations in growth rate and in age at first ... -

Observations of abundance, stock composition, body size and food of postsmolts of Atlantic salmon in the NE Atlantic during summer
Holst, Jens Christian; Hansen, Lars Petter; Holm, Marianne (ICES CM Documents;1996/M:4, Working paper, 1996)Postsmolt Atlantic salmon were caught during pelagic trawl surveys in the Norwegian Sea in July-August, 1991 and 1995, and off the Hebrides in May-June 1995. Using the swept area technique abundance estimates of postmolts ... -
Oppsummering av kunnskapsstatus innen rømming av oppdrettslaks - Tiltak for gjenfangst etter rømming
Skilbrei, Ove; Holst, Jens Christian; Holm, Marianne (Fisken og havet, Research report, 2006)Monitoring and statistics of the amount of escaped salmonids in the sea in Norway is limited.

Poor feeding opportunities and reduced condition factor for salmon post-smolts in the Northeast Atlantic Ocean
Utne, Kjell Rong; Pauli, Beatriz Diaz; Haugland, Monika; Jacobsen, Jan Arge; Maoileidigh, Niall O´; Melle, Webjørn Raunsgård; Broms, Cecilie; Nøttestad, Leif; Holm, Marianne; Thomas, Katie; Wennevik, Vidar (Peer reviewed; Journal article, 2021)During the last few decades, many wild Atlantic salmon populations have declined dramatically. One possible contributing factor for the decline is reduced prey availability at sea. Here, we examine post-smolt diet and ... -
