Harvest control rules in modern fisheries management
Kvamsdal, Sturla F; Eide, Arne; Ekerhovd, Nils-Arne; Enberg, Katja; Gudmundsdottir, Asta; Hoel, Alf Håkon; Mills, Katherine E.; Mueter, Franz J.; Ravn-Jonsen, Lars; Sandal, Leif Kristoffer; Stiansen, Jan Erik; Vestergaard, Niels (Journal article; Peer reviewed, 2016-07-20)Harvest control rules have become an important tool in modern fisheries management, and are increasingly adopted to provide continuity in management practices, to deal with uncertainty and ecosystem considerations, and to ... -
Harvesting Strategies in a Fish Stock Dominated by Low-frequency Variability: The Norwegian Spring-spawning Herring (Clupea harengus)
Kaitala, Veijo; Jonzén, Niclas; Enberg, Katja (Journal article; Peer reviewed, 2003)Heavy positively autocorrelated natural fluctuations in a fisheries stock level are problematic for fisheries management, and collapses in the stock dynamics are difficult to avoid. In this paper, we compare three different ... -
Impact of size-selective mortality on waterfleas (Daphnia)
Wathne, Ingrid; Jensen, Knut Helge; Enberg, Katja; Heino, Mikko (ICES CM Documents;2010/M:25, Working paper, 2010)Size‐selective predation shapes species and induces changes in life‐history traits. Exposure to sizeselective mortality will make being the size that is vulnerable dangerous and possibly fatal; thus, if small individuals ... -

The impacts of different management strategies and environmental forcing in ecological communities
Enberg, Katja; Fowler, Mike S.; Ranta, Esa (Journal article; Peer reviewed, 2006-07-05)Understanding the effects of population management on the community a target species belongs to is of key importance for successful management. It is known that the removal or extinction of a single species in a community ... -
Implications of fisheries-induced evolution for stock rebuilding and recovery
Enberg, Katja; Jørgensen, Christian; Dunlop, Erin S.; Heino, Mikko; Dieckmann, Ulf (Journal article; Peer reviewed, 2009-07-31)Worldwide depletion of fish stocks has led fisheries managers to become increasingly concerned about rebuilding and recovery planning. To succeed, factors affecting recovery dynamics need to be understood, including the ... -
Implications of fisheries-induced evolution for stock rebuilding and recovery
Enberg, Katja; Jørgensen, Christian; Dunlop, Erin S.; Heino, Mikko; Dieckmann, Ulf (ICES CM documents;2010/M:29, Working paper, 2010)Fishing-induced evolution has the potential to change life-history and other characters of exploited stocks. Here we study the rebuilding and recovery of an exploited stock with en individual-based eco-genetic model ... -
Life-history implications of the allometric scaling of growth
Boukal, David S.; Dieckmann, Ulf; Enberg, Katja; Heino, Mikko; Jørgensen, Christian (Journal article; Peer reviewed, 2014-05-27)Several phenomenological descriptions, such as the von Bertalanffy growth model, have been widely used to describe size-at-age and individual growth across a diverse range of organisms. However, for modelling life histories, ... -

Modelling and interpreting fish bioenergetics – a role for behaviour, life-history traits, and survival trade-offs
Jørgensen, Christian; Enberg, Katja; Mangel, Marc (Journal article; Peer reviewed, 2016-01-14)Bioenergetics is used as the mechanistic foundation of many models of fishes. As the context of a model gradually extends beyond pure bioenergetics to include behaviour, life-history traits and function and performance of ... -
Pre-catch and discard mortality in Northeast Atlantic herring and mackerel fisheries: consequences for stock estimates and advice
Tenningen, Maria; Zimmermann, Fabian; Enberg, Katja (Peer reviewed; Journal article, 2021)Unaccounted mortality caused by discarding or pre-catch losses is a major challenge for fisheries management. In pelagic fisheries, a considerable proportion of catches may be lost due to intentional release of unwanted ... -
Predicting density-dependent somatic growth in Norwegian spring-spawning herring
Stenevik, Erling Kåre; Hølleland, Sondre Nedreås; Enberg, Katja; Høines, Åge Sigurd; Salthaug, Are; Slotte, Aril; Vatnehol, Sindre; Aanes, Sondre (Peer reviewed; Journal article, 2022)Density-dependent growth, which might influence the effects of fisheries on a population, is often ignored when management strategies are evaluated, mainly due to a lack of appropriate models readily available to be ... -

Rapid life-history evolution in a wild Daphnia pulex population in response to novel size-dependent predation
Wathne, Ingrid; Enberg, Katja; Jensen, Knut Helge; Heino, Mikko Petteri (Peer reviewed; Journal article, 2020)The effect of size-selective predation on prey communities and their traits is well documented, but the relative roles of genetic adaptation and phenotypic plasticity continue to be debated. We looked for evidence of genetic ... -
