Within-River Spawning Migration of Adult Atlantic Salmon: A Case Study From a Small River in Western Norway
(Master thesis, 2025-06-02)Within-river spawning migration is essential to the reproductive success of Atlantic salmon. With ongoing population declines, data-driven information on within-river migration, and the factors affecting movement patterns ... -
Transcriptional Regulation of Sensory- and Gland Cell Differentiation in Nematostella vectensis
(Doctoral thesis, 2025-07-01)Under embryonal utvikling gir stam- og progenitorcellepopulasjoner opphav til spesialiserte celler som danner organismen. Progenitorceller gjennomgår flere runder med deling, noe som gradvis begrenser deres utviklingspotensial ... -
Development and evaluation of reference feed intake models for meagre (Argyrosomus regius)
(Journal article; Peer reviewed, 2025)The aim of the study was to identify a basic reference feed intake model to facilitate understanding of the impact of temperature as the key environmental factor, along with body weight and dietary composition. These basic ... -
Formation, sources of variation, and health of the postcranial axial skeleton in selected salmonids
(Doctoral thesis, 2025-07-02)Atlantisk laks (Salmo salar) og regnbueørret (Oncorhynchus mykiss) er viktige oppdrettsarter globalt. Oppdrett av disse artene er forbundet med utfordringer knyttet til redusert vekst, ulike sykdommer og lakselus. I tillegg ... -
Premises for digital twins reporting on Atlantic salmon wellbeing
(Journal article; Peer reviewed, 2025)Many species of fish, birds and mammals commonly live in human captivity; Atlantic salmon Salmo salar is one of them. The international legal status of the welfare of captive animals is slowly developing and still requires ... -
Effect of heterozygosity, ploidy and incubation temperature on post-cranial axial skeletal meristics and deformities in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2025)The teleostean post-cranial axial skeleton is a highly specialized structure for an aquatic mode of life. However, there is limited knowledge regarding parental contributions, early-life environmental impacts on its meristic ... -
Effects of fish behaviour on abundance and length frequency estimates from in-trawl stereo cameras
(Journal article; Peer reviewed, 2025)In-trawl stereo cameras can provide fine-scale spatial and temporal information on species along the trawl path and record small-sized and fragile organisms typically absent from catches. Reliable estimates of abundance ... -
Vertebral deformities in cultured big size Rainbow Trout: Radiological analysis from juvenile to harvest size
(Journal article; Peer reviewed, 2025)Vertebral deformities are a big challenge in Rainbow Trout seawater aquaculture. However, supportive scientific literature is missing. The present study used radiology to follow the development of vertebral deformities in ... -
Vertebrate decision making leads to the interdependence of behaviour and wellbeing
(Journal article; Peer reviewed, 2025)Animal behaviour is commonly modelled by fitness-based optimization or individual-based simulation. Each has limitations: the premises for fitness-maximizing modelling are violated in most ecological and sociobiological ... -
FishMet: A Digital Twin Framework for Appetite, Feeding Decisions and Growth in Salmonid Fish
(Journal article; Peer reviewed, 2025)Salmonids are important fish species in aquaculture in countries in the temperate zone. Optimisation of feeding in next-generation precision fish farming requires developing models for decision support and process control. ... -
Global impoverishment of natural vegetation revealed by dark diversity
(Journal article; Peer reviewed, 2025)Anthropogenic biodiversity decline threatens the functioning of ecosystems and the many benefits they provide to humanity1. As well as causing species losses in directly affected locations, human influence might also reduce ... -
Early life stages of fish under ocean alkalinity enhancement in coastal plankton communities
(Journal article; Peer reviewed, 2024)Ocean alkalinity enhancement (OAE) stands as a promising carbon dioxide removal technology. Yet, this solu- tion to climate change entails shifts in environmental drivers with unknown consequences for marine fish that are ... -
A deep dive into the genetic Landscape of Norwegian Coastal Cod
(Doctoral thesis, 2025-06-17)Bakgrunn: Atlanterhavstorsken (Gadus morhua) er en økonomisk viktig fisk utbredt over store deler av det nordlige Atlanterhavet, hvor Norge huser noen av de mest tallrike torskebestandene og fiskeriene som fortsatt finnes. ... -
Salinity effect on growth and yield of two populations of Sugar kelp (Saccharina latissima) from Middelfart, Denmark and Kiel, Germany
(Master thesis, 2025-03-17)This study investigated how low salinity affected growth, photosynthetic rate, and physiological responses of Saccharina latissima. Two populations were compared to assess if there were any differences in salinity tolerance ... -
Viral harmony : From conflict to coexistence
(Doctoral thesis, 2025-06-12)Virus spiller en avgjørende rolle i marine økosystemer ved å forme strukturen til mikrobielle samfunn, drive evolusjonære prosesser og påvirke globale biogeokjemiske kretsløp. Denne avhandlingen undersøker den skjøre ... -
Transcriptome analysis reveals effects of ethynylestradiol and bisphenol A on multiple endocrine and metabolic pathways in the pituitary and liver of female Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2024)Introduction: The pituitary and liver are among the main sites of action of estrogens in fish. Years of research has shown that xenoestrogens can interfere with functions of estrogens. There is however incomplete understanding ... -
Present and future distribution of the deep-sea habitat-forming sponge - Pheronema carpenteri ( Thomson, 1869) in a changing ocean
(Journal article; Peer reviewed, 2024)Sponges play vital roles in the ecosystem function of the deep sea. Some species, such as the birds' nest sponge Pheronema carpenteri, can form highly structured and dense habitats (i.e., aggregations), which contribute ... -
