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. ... -
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 ... -
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 ... -
“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 ... -
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 ... -
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 ... -
The effects of different feed ratios on growth, welfare rating and maturation in juvenile Atlantic salmon (Salmo salar ,L)
(Master thesis, 2023-10-20)The world population is increasing day by day and has surpassed 8 billion, and there will continue to be high demands of more protein to feed the world. Salmon farming is a rapidly growing industry and has been for the ... -
Environmental Drivers of Demersal Fish and Crustacean Community Structure in West Norwegian Fjords
(Master thesis, 2023-09-01)Norwegian fjords, with their complex bathymetry and deep basins, are easily accessible study areas for deep sea communities. Impacts of climate change and increasing pressure from anthropogenic activities on fjord ecosystems, ... -
Size distribution pattern and abundance of Periphylla periphylla in western Norwegian fjords
(Master thesis, 2023-10-02) -
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?
(Journal article; Peer reviewed, 2024) -
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 ...
