Can less be more? Effects of reduced frequency of surveys andstock assessments
Zimmermann, Fabian; Enberg, Katja (Journal article; Peer reviewed, 2016-08-07)Uncertain and inaccurate estimates are a prevailing problem in stock assessment, despite increasingly sophisticated estimation methods and substantial usage of scientific and financial resources. Annual scientific surveys ... -
Common trends in recruitment dynamics of north-east Atlantic fish stocks and their links to environment, ecology and management
Zimmermann, Fabian; Claireaux, Marion; Enberg, Katja (Journal article; Peer reviewed, 2019)Recruitment dynamics are challenging to assess or predict because of the many underlying drivers that vary in their relevance over time and space. Stock size, demographic and trait composition, condition and distribution ... -
Density-independent mortality at early life stages increases the probability of overlooking an underlying stock-recruitment relationship
Zimmermann, Fabian; Enberg, Katja; Mangel, Marc (Peer reviewed; Journal article, 2021)Abstract Beverton and Holt’s (1957) monograph contributed a widely used stock–recruitment relationship (BH-SRR) to fisheries science. However, because of variation around a presumed relationship between spawning biomass ... -
Drivers of the summer-distribution of Northeast Atlantic mackerel (Scomber scombrus) in the Nordic Seas from 2011 to 2017; a Bayesian hierarchical modelling approach.
Nikolioudakis, Nikolaos; Skaug, Hans J.; Olafsdottir, Anna H.; Jansen, Teunis; Jacobsen, Jan Arge; Enberg, Katja (Journal article; Peer reviewed, 2019)Identifying factors that are statistically correlated with the geographical distribution dynamics of a species can facilitate our understanding of causal physiological and ecological relationships. Northeast Atlantic (NEA) ... -
Eight decades of adaptive changes in herring reproductive investment: the joint effect of environment and exploitation
Claireaux, Marion; dos Santos Schmidt, Thassya Christina; Olsen, Esben Moland; Slotte, Aril; Varpe, Øystein; Heino, Mikko Petteri; Enberg, Katja (Peer reviewed; Journal article, 2020)Reproductive investment is a central trait for population dynamics and productivity. Fishing and environmental variations are major drivers affecting population structure, dynamics, and adaptation of life-history and ... -
Environmental drivers of herring growth and how the perception shifts with time series length
Claireaux, Marion; Zimmermann, Fabian; Ernande, Bruno; Heino, Mikko Petteri; Enberg, Katja (Peer reviewed; Journal article, 2022)Growth is a key component of population dynamics and, thus, fisheries management, yet drivers of its variations are often poorly understood. Using individual data collected over 80 years, we explored how environmental ... -
Environmental stressors may cause unpredicted, notably lagged life-history responses in adults of the planktivorous Atlantic herring
dos Santos Schmidt, Thassya Christina; Devine, Jennifer Ann; Slotte, Aril; Claireaux, Marion; Johannessen, A; Enberg, Katja; Oskarsson, Gudmundur; Kennedy, James; Kurita, Yutaka; Kjesbu, Olav Sigurd (Peer reviewed; Journal article, 2020)Here we challenge traditional views on the direction of change in teleost body condition and reproductive traits in response to abiotic and biotic factors by studying the data-rich, planktivorous Norwegian spring-spawning ... -
Evolutionary effects of fishing gear on foraging behavior and life-history traits
Claireaux, Marion; Jørgensen, Christian; Enberg, Katja (Journal article; Peer reviewed, 2018)Fishing gears are designed to exploit the natural behaviors of fish, and the concern that fishing may cause evolution of behavioral traits has been receiving increasing attention. The first intuitive expectation is that ... -
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 ... -
Me, myself and I -Teachers’ self-motivation and sense of responsibility determine the use of active learning methods
Enberg, Katja; Steen, Ida Helene; Ellingsen, Ståle (Peer reviewed; Journal article, 2019) -
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 ...
