Blue mussels in western Norway have vanished where in reach of crawling predators
(Journal article; Peer reviewed, 2023)Blue mussels (Mytilus spp.) are declining around the world. In western Norway, they have widely disappeared from rocky shores but still thrive on floating structures. Other refugia are cracks in rocks, exposed sites, and ... -
Application of CRISPR-based gene editing tools in Atlantic salmon
(Doctoral thesis, 2024-05-15)Atlantisk laks er den viktigaste arten i norsk havbruksnæring. Næringa i Noreg er i dag ramma av fleire berekraftsufordringar, til dømes genetisk innblanding av rømt laks, og spreiing av smittsame sjukdommar. Dette påverkar ... -
Behaviour of anadromous brown trout (Salmo trutta) in a hydropower regulated freshwater system
(Journal article; Peer reviewed, 2023)Many Norwegian rivers and lakes are regulated for hydropower, which afects freshwater ecosystems and anadromous fish species, such as sea trout (Salmo trutta). Lakes are an important feature of many anadromous river systems. ... -
Ten priority questions for increasing the consistency and success in hatchery production of the European flat oyster for habitat restoration
(Journal article; Peer reviewed, 2023)The European flat oyster, Ostrea edulis, once formed extensive reef habitats throughout European seas and estuaries. These reefs are now largely functionally extinct, yet interest and support for their restoration is rapidly ... -
Injectable In Situ Crosslinking Hydrogel for Autologous Fat Grafting
(Journal article; Peer reviewed, 2023)Autologous fat grafting is hampered by unpredictable outcomes due to high tissue resorption. Hydrogels based on enzymatically pretreated tunicate nanocellulose (ETC) and alginate (ALG) are biocompatible, safe, and present ... -
Salmon louse labial gland enzymes: implications for host settlement and immune modulation
(Journal article; Peer reviewed, 2024)Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin. ... -
Impacts of predation by Eurasian otters on Atlantic salmon in two Norwegian rivers
(Journal article; Peer reviewed, 2023)1. The return of the Eurasian otter (Lutra lutra) to western Norway has sparked human–predator conflicts because otters prey on vulnerable Atlantic salmon (Salmo salar) populations. Although predation may not be the ultimate ... -
Tracking freshwater browning and coastal water darkening from boreal forests to the Arctic Ocean
(Journal article; Peer reviewed, 2023)The forest cover of Northern Europe has been steadily expanding during the last 120 years. More terrestrial vegetation and carbon fixation leads to more export to surface waters. This may cause freshwater browning, as more ... -
“Show me how to use a microscope” – The development and evaluation of certification as direct assessment of practical lab skills
(Journal article; Peer reviewed, 2023)Practical lab skills are rarely directly assessed. To improve constructive alignment between the described learning outcomes of practical skills and assessment, we developed and tested a certification procedure for microscopy ... -
Environmentally realistic concentrations of chlorinated, brominated, and fluorinated persistent organic pollutants induce the unfolded protein response as a shared stress pathway in the liver of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2023)In the North Sea and North Atlantic coastal areas, fish experience relatively high background levels of persistent organic pollutants. This study aimed to compare the mode of action of environmentally relevant concentrations ... -
Life in the fast lane: Revisiting the fast growth—High survival paradigm during the early life stages of fishes
(Journal article; Peer reviewed, 2023)Early life survival is critical to successful replenishment of fish populations, and hypotheses developed under the Growth-Survival Paradigm (GSP) have guided investigations of controlling processes. The GSP postulates ... -
Socio-cultural values and biophysical supply: How do afforestation and land abandonment impact multiple ecosystem services?

Methods for tagging an ectoparasite, the salmon louse Lepeophtheirus salmonis
(Journal article; Peer reviewed, 2024)Monitoring individuals within populations is a cornerstone in evolutionary ecology, yet individual tracking of invertebrates and particularly parasitic organisms remains rare. To address this gap, we describe here a method ... -
Occurrence of salmonid alphavirus and piscine orthoreovirus-1 infections in migrating salmon (Salmo salar L.) post-smolt in western Norway
(Journal article; Peer reviewed, 2023)Viral diseases are a serious problem in Atlantic salmon (Salmo salar L.) farming in Norway, often leading to reduced fish welfare and increased mortality. Disease outbreaks in salmon farms may lead to spread of viruses to ... -
Five reasons to take the precautionary approach to deep sea exploitation
(Journal article, 2023)Extractive activities in the deep sea are poised to advance faster than the science needed to evaluate risks. Here, we call for a strong precautionary approach in developing these industries. -
Diminishing returns on labour in the global marine food system
(Journal article; Peer reviewed, 2023)Technological advances over the past century have greatly reduced the proportion of human labour required to produce the world’s food. On land, these advances have continually increased yields, feeding a growing human ... -
DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity
(Journal article; Peer reviewed, 2023)Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ... -
Positioning aquatic animals with acoustic transmitters
(Journal article; Peer reviewed, 2023)Geolocating aquatic animals with acoustic tags has been ongoing for decades, relying on the detection of acoustic signals at multiple receivers with known positions to calculate a 2D or 3D position, and ultimately recreate ...
