Successful growth of coastal marine microalgae in wastewater from a salmon recirculating aquaculture system
(Journal article; Peer reviewed, 2024)As global demand for seafood increases, recirculating aquaculture systems (RAS) have gained prominence for sustainable fish rearing. The sustainability of RAS still requires improvement, particularly managing the fish ... -
Genetic monitoring uncovers long-distance marine feeding coupled with strong spatial segregation in sea trout (Salmo trutta L.) consistent at annual and decadal time scales
(Journal article; Peer reviewed, 2024)Genetic data have greatly increased means to understand fish marine migration behaviours at large spatial scale within a quantitative framework. The anadromous sea trout is a prized target of recreational fishery and an ... -
Coherent long-term body-size responses across all Northwest Atlantic herring populations to warming and environmental change despite contrasting harvest and ecological factors
(Peer reviewed; Journal article, 2024)Body size is a key component of individual fitness and an important factor in the structure and functioning of populations and ecosystems. Disentangling the effects of environmental change, harvest and intra- and inter-specific ... -
Condition factor tailored to lumpfish (Cyclopterus lumpus) used as cleaner fish in salmonid farms
(Peer reviewed; Journal article, 2024)Lumpfish (Cyclopterus lumpus) are extensively used as part of the control measures against salmon lice in fish farms. In recent years, there has been an increased focus on lumpfish welfare, and how to increase survival of ... -
Haulout Patterns of Harbour Seal Colonies in the Norwegian Skagerrak, as Monitored through Time-Lapse Camera Surveys
(Peer reviewed; Journal article, 2024)Harbour seals (Phoca vitulina) are part of the Norwegian coastal ecosystem and can be observed on skerries, islands, and sandbanks along the coastline, sometimes in close proximity to inhabited areas. In this study, we ... -
Importance of environmental signals for cardiac morphological development in Atlantic salmon
(Journal article; Peer reviewed, 2024)The hearts of salmonids display remarkable plasticity, adapting to various environmental factors that influence cardiac function and demand. For instance, in response to cold temperature, the salmonid heart undergoes growth ... -
Sex-specific vertical movements of spawning atlantic cod in coastal habitats inferred from acoustic telemetry
(Peer reviewed; Journal article, 2024)Fish spawning location and behaviour can be challenging to detect, especially in deep water. Here we utilise two large acoustic telemetry datasets from western and mid Norway to study the vertical movement dimension of ... -
Towards more culturally aware teaching of ‘scientific practices’: Understanding science as a social-historical human endeavour
(Peer reviewed; Journal article, 2024)‘Scientific practices’ are included as a core element in Norway’s new science curriculum as of 2020. In dialogue with international research on the teaching and learning of scientific practices, Haug et al. (2021) have ... -
Higher vitamin B12 levels in neurodevelopmental disorders than in healthy controls and schizophrenia A comparison among participants between 2 and 53 years
(Peer reviewed; Journal article, 2020)Recent studies suggest that both high and low levels of vitamin B12 (vitB12) may have negative health impacts. We measured VitB12 in patients with the Neurodevelopmental disorders (ND) (n = 222), comprised of Autism Spectrum ... -
Exploring freshwater challenges for conservation efforts : Insights into threatened and invasive fish species using environmental DNA
(Doctoral dissertations at University of Agder; no. 490, Doctoral thesis, 2024)Ferskvannsøkosystemer trues av habitatendringer, menneskeskapte barrierer, fremmede arter, forurensning, overfiske og klimaendringer. Selv om internasjonale lover og forskrifter støtter bevaring, kreves det fortsatt betydelig ... -
Personality of sea trout : A case study on ecology, conservation and dynamics in coastal Skagerrak
(Doctoral dissertations at University of Agder;no. 228, Doctoral thesis, 2019)Variation in fish behaviour seems to be an important part of species’ lifehistory and adaptation to environmental change. Interestingly, variation occurs not only in response to environmental cues, but can also be consistently ... -
Seascape ecology of Atlantic cod (Gadus morhua) in coastal Skagerrak: population structure, connectivity, and role in fish assemblage
(Doctoral dissertations at University of Agder;no. 294, Doctoral thesis, 2020)Atlantic cod populations along the Norwegian Skagerrak coast consist of two known ecotypes. During the last decade, there has been a dramatic decline of larger cod and other piscivorous fish species in eastern Skagerrak. ... -
Seasonality in phytoplankton communities and production in three Arctic fjords across a climate gradient
(Peer reviewed; Journal article, 2024)Phytoplankton communities and production in Arctic fjords undergo strong seasonal variations. Phytoplankton blooms are periods with high primary production, leading to elevated algal biomass fueling higher trophic levels. ... -
Effect of environmental drivers on the spatiotemporal distribution of mackerel at age in the Nordic Seas during 2010-20
(Peer reviewed; Journal article, 2024)A joint spatio–temporal distribution model of mackerel (ages 3–10) was developed to investigate the age-based responses of mackerel to three environmental drivers: sea surface temperature (SST), mixed layer depth, and ... -
Diatom-mediated food web functioning under ocean artificial upwelling
(Peer reviewed; Journal article, 2024)Enhancing ocean productivity by artificial upwelling is evaluated as a nature-based solution for food security and climate change mitigation. Fish production is intended through diatom-based plankton food webs as these are ... -
Stakeholders' perception and willingness-to-pay for an aquaculture-based fisheries enhancement program for coastal cod in Southern Norway
(Peer reviewed; Journal article, 2024)The coastal cod fishery in Southern Norway has experienced a significant decline over the last decades. Recreational fishing for cod in the eastern part of the country is currently banned. Fisheries managers have adopted ... -
Evaluation of mitigation measures for Atlantic salmon and brown trout at hydropower plants and their prospect as selective agents
(Doctoral dissertations at University of Agder;no. 314, Doctoral thesis, 2021)Renewable energy contributes towards the world`s growing energy demands and urgent need for mitigating climate change.
