Can less be more? Effects of reduced frequency of surveys and stock assessments
Zimmermann, Fabian; Enberg, Katja (Peer reviewed; Journal article, 2016)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 (Peer reviewed; Journal article, 2019-03-13)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 (Journal article; Peer reviewed, 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 (Peer reviewed; Journal article, 2019-03)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 (Journal article; Peer reviewed, 2021)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 ... -
Engaging students in SDG 14 by placing them at the centre of their own learning: SDG214 at the University of Bergen as an example
Enberg, Katja (Chapter, 2021)Educating students on the sustainable development goals (SDGs) calls for teaching where students are at the centre of their own learning. Sustainability questions are ‘wicked problems’, where no single, correct answer ... -
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 (Journal article; Peer reviewed, 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 (Journal article; Peer reviewed, 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 (Peer reviewed; Journal article, 2018-11)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 ... -
Fine-scale diet data reveal spatial variation in predator–prey interactions in Norwegian fjords
Tengvall, Jessica; Søvik, Guldborg; Enberg, Katja; Lindstrøm, Ulf Ove; Strand, Mette; Pedersen, Torstein; Strand, Hans Kristian; Zimmermann, Fabian (Journal article; Peer reviewed, 2024)1. Predator–prey interactions in time and space determine stock productivity, making them an important consideration when managing marine resources, rebuilding stocks or considering reopening a fishery. 2. We analysed ... -
Fishing for answers

An interdisciplinary, student-active course on UN Sustainable Development Goal 14: Life below water
Enberg, Katja (Journal article; Peer reviewed, 2021)Educating student to respond to Sustainable Development Goals (SDGs) calls for teaching and learning where students are at the centre of their own learning. Sustainability questions are ‘wicked problems’, where no single, ... -
Joining forces for sustainability education – Sustainability Education Collective at the University of Bergen
Enberg, Katja; Harlap, Yael (Journal article; Peer reviewed, 2021)Agenda 2030 and its Sustainable Development Goals (SDGs) have resulted in a heightened focus on sustainability in Norwegian – and global – academia. Sustainability Education requires innovative pedagogy and active, ... -
Life-history implications of the allometric scaling of growth
Boukal, David S.; Dieckmann, Ulf; Enberg, Katja; Heino, Mikko Petteri; Jørgensen, Christian (Peer reviewed; Journal article, 2014-10-21)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, ... -
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 (Journal article; Peer reviewed, 2019)Extended use of laboratory and field courses makes biology a discipline considering itself as a habitual practitioner of active learning strategies. We investigated how widely the faculty at the Department of Biological ... -
Modelling and interpreting fish bioenergetics: a role for behaviour, life-history traits and survival trade-offs
Jørgensen, Christian; Enberg, Katja; Mangel, Marc (Peer reviewed; Journal article, 2016-01)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 ... -

Tenningen, Maria; Zimmermann, Fabian; Enberg, Katja (Journal article; Peer reviewed, 2021)Unaccounted mortality caused by discarding or pre-catch losses is a major challenge for fisheries management.
