Spawning stock and recruitment in North Sea cod shaped by food and climate
Olsen, Esben Moland; Ottersen, Geir; Llope, Marcos; Chan, Kung-Sik; Beaugrand, Grégory; Stenseth, Nils Christian (Journal article; Peer reviewed, 2010-09-01)In order to provide better fisheries management and conservation decisions, there is a need to discern the underlying relationship between the spawning stock and recruitment of marine fishes, a relationship which is ... -

Due to the increasing degree ... -

Stable coexistence of genetically divergent Atlantic cod ecotypes at multiple spatial scales
Knutsen, Halvor; Jorde, Per Erik; Hutchings, Jeffrey; Hemmer-Hansen, Jakob; Grønkjær, Peter; Jørgensen, Kris-Emil Mose; André, Carl; Sodeland, Marte; Albretsen, Jon; Olsen, Esben Moland (Journal article; Peer reviewed, 2018)Coexistence in the same habitat of closely related yet genetically different populations is a phenomenon that challenges our understanding of local population structure and adaptation. Identifying the underlying mechanisms ... -
Technological creep masks continued decline in a lobster (Homarus gammarus) fishery over a century
Kleiven, Alf Ring; Espeland, Sigurd Heiberg; Stiansen, Stian; Ono, Kotaro; Zimmermann, Fabian; Olsen, Esben Moland (Peer reviewed; Journal article, 2022)Fishery-dependent data are frequently used to inform management decisions. However, inferences about stock development based on commercial data such as Catch-Per-Unit-Effort (CPUE) can be severely biased due to a phenomenon ... -

Freitas, Carla; Olsen, Esben Moland; Knutsen, Halvor; Albretsen, Jon; Moland, Even (Journal article; Peer reviewed, 2015-11-23) -
The evolving story of catadromy in the European eel (Anguilla anguilla)

Time at risk: individual spatial behaviour drives fitness and marine protected area effectiveness
Villegas-Ríos, David; Claudet, Joachim; Freitas, Carla; Moland, Even; Thorbjørnsen, Susanna Huneide; Alonso-Fernández, Alexandre; Olsen, Esben Moland (Peer reviewed; Journal article, 2021)The effectiveness of Marine Protected Areas (MPAs) depends on the mobility of the populations that are the target of protection, with sedentary species likely to spend more time under protection even within small MPAs. ... -
Torsk på Skagerrakkysten; mengde, dødelighet og kondisjon
Gjøsæter, Jakob; Knutsen, Jan Atle; Knutsen, Halvor; Olsen, Esben Moland; Enersen, Kate; Enersen, Svein Erik (Fisken og havet, Research report, 2007)Kysttorsken har historisk vært den viktigste fiskearten på Skagerrakkysten. I de senere år har fiskere i østre deler av Skagerrak gitt utrykk for at kysttorskbestanden er blitt kraftig redusert. Rapporten her presenterer ... -
Total Catch of a Red-Listed Marine Species Is an Order of Magnitude Higher than Official Data
Kleiven, Alf Ring; Olsen, Esben Moland; Vølstad, Jon Helge (Journal article; Peer reviewed, 2012-02-17)Accurate information on total catch and effort is essential for successful fisheries management. Officially reported landings, however, may be underestimates of total catch in many fisheries. We investigated the fishery ... -
Warming Accelerates the Onset of the Molecular Stress Response and Increases Mortality of Larval Atlantic Cod
Oomen, Rebekah Alice; Knutsen, Halvor; Olsen, Esben Moland; Jentoft, Sissel; Stenseth, Nils Christian; Hutchings, Jeffrey (Peer reviewed; Journal article, 2022)Temperature profoundly affects ectotherm physiology. Although differential thermal responses influence fitness, thus driving population dynamics and species distributions, our understanding of the molecular architecture ...
