Artificial light improves size selection for northern shrimp (Pandalus borealis) in trawls
(Peer reviewed; Journal article, 2021)Size selection in the northern shrimp (Pandalus borealis) trawl fisheries is a widely studied topic. While the focus has largely been on codend and grid selectivity, studies have shown the importance of other design changes ... -
Assessing the performance of statistical classifiers to discriminate fish stocks using Fourier analysis of otolith shape
(Peer reviewed; Journal article, 2019)The assignment of individual fish to its stock of origin is important for reliable stock assessment and fisheries management. Otolith shape is commonly used as the marker of distinct stocks in discrimination studies. Our ... -

Atlantic salmon survival at sea: temporal changes that lack regional synchrony
(Peer reviewed; Journal article, 2022)Spatial and temporal synchrony in abundance or survival trends can be indicative of whether populations are affected by common environmental drivers. In Atlantic salmon (Salmo salar), return rates to natal rivers have ... -
Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness
(Peer reviewed; Journal article, 2021)In most trawl fisheries, drag forces tend to close the meshes in large areas of diamond mesh codends, negatively affecting their selective potential. In the Barents Sea deep-water shrimp (Pandalus borealis) trawl fishery, ... -

Detecting significant retrospective patterns in state space fish stock assessment
(Peer reviewed; Journal article, 2023)Retrospective patterns are commonly investigated to validate fish stock assessment models. A widely applied measure for retrospective bias is Mohn’s ρ and corresponding retrospective plots. However, retrospective patterns ... -
Environmental drivers of herring growth and how the perception shifts with time series length
(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 ... -
Feeding interactions between Atlantic salmon (Salmo salar) postsmolts and other planktivorous fish in the Northeast Atlantic
(Peer reviewed; Journal article, 2020) -
Habitat use and growth of yellow-stage European eel in coastal and freshwater ecosystems in Norway
(Peer reviewed; Journal article, 2022)Many anguillid eel species display facultative catadromy. Some eel spend their entire life cycle in marine coastal areas, but the geographical extent of this, especially at the extremes of their distributional ranges, is ... -

Inclusion of recreational fishing in data-limited stocks: a case study on Norway lobster (Nephrops norvegicus) in Norway
(Others, 2022)Recreational and semi-subsistence fisheries are challenging to monitor but can act as precursors of developments in commercial fisheries, contributing information in data-limited situations. We compared trends in commercial ... -
Inverse method applied to autonomous broadband hydroacoustic survey detects higher densities of zooplankton in near-surface aggregations than vessel-based net survey
(Peer reviewed; Journal article, 2022)Throughout all oceans, aggregations of zooplankton and ichthyoplankton appear as horizontal sound scattering layers (SSLs) when detected with active acoustic techniques. Quantifying the composition and density of these ... -
Latent gaussian models to decide on spatial closures for bycatch management in the barents sea shrimp fishery
(Peer reviewed; Journal article, 2016) -
Long-term interplay between harvest regimes and biophysical conditions may lead to persistent changes in age at sexual maturity of Northeast Arctic cod (Gadus morhua)
(Peer reviewed; Journal article, 2022)This investigation commenced by constructing principal maturation schedule equations as a function of fishing mortality (F), key biophysical factors and a term attributed to fisheries-induced adaptive change (FIAC). Following ... -
Potential for codends with shortened lastridge ropes to replace mandated selection devices in demersal trawl fisheries
(Peer reviewed; Journal article, 2021)In many trawl fisheries, codend size selectivity is supplemented by adding selection devices to the gear. In the Barents Sea gadoid fishery, combining diamond mesh codends with sorting grids is compulsory. However, the use ... -
Potential sources of bias in the climate sensitivities of fish otolith biochronologies
(Peer reviewed; Journal article, 2020)Analysis of growth increments in the hard parts of animals (e.g., fish otoliths) can be used to assess how organisms respond to variability in environmental conditions. In this study, mixed-effects models were applied to ... -
Predation of Atlantic salmon across ontogenetic stages and impacts on populations
(Peer reviewed; Journal article, 2023)Managers and stakeholders increasingly ask whether predation is a driving force behind the poor status of many species, and whether predator control is likely to be a successful management action to intervene. We review ... -

Recorded captures of American lobster (Homarus Americanus) in Swedish waters and an observation of predation on the European lobster (Homarus Gammarus)
