Effects of fish farm activities on the sponge Weberella bursa, and its associated microbiota
(Peer reviewed; Journal article, 2021)Sustained growth of world-wide sea farming and the search of optimal growing conditions have driven several countries, including Norway, to establish new finfish sites in more exposed, high current locations. Characterized ... -
The potential for cleaner fish-driven evolution in the salmon louse Lepeophtheirus salmonis: Genetic or environmental control of pigmentation?
(Peer reviewed; Journal article, 2021)The parasitic salmon louse represents one of the biggest challenges to environmentally sustainable salmonid aquaculture across the globe. This species also displays a high evolutionary potential, as demonstrated by its ... -
Fluorolice - Final report for FHF project 901508
(Rapport fra havforskningen;2021 - 30, Research report, 2021)Salmon lice ( Lepeophtheirus salmonis ) represent a substantial obstacle for the sustainability of salmon farming (Torrissen, et al. 2013; Vollset, et al. 2018). As such, there are many avenues of research that aim to ... -
Potential sources of marine plastic from survey beaches in the Arctic and Northeast Atlantic
(Peer reviewed; Journal article, 2021)Plastic litter is accumulating on pristine northern European beaches, including the European Arctic, and questions remain about the exact origins and sources. Here we investigate plausible fishery and consumer-related ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
(Peer reviewed; Journal article, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
Fish protection during fish production. Organizational conditions for fish welfare
(Peer reviewed; Journal article, 2021)Too many salmon die during production at Norwegian fish farms. Earlier research shows that most farmed salmon die in operations partly related to protection of the wild salmon (from salmon lice), but it is not known how ... -
Temperate fish detection and classification: a deep learning based approach
(Peer reviewed; Journal article, 2021)A wide range of applications in marine ecology extensively uses underwater cameras. Still, to efficiently process the vast amount of data generated, we need to develop tools that can automatically detect and recognize ... -
Effects of mine tailing exposure on early life stages of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)
(Peer reviewed; Journal article, 2021)Mining and processing of minerals produce large quantities of tailings as waste. Some countries, including Norway, allow disposal of mine tailings in the sea. In this study we investigated the impacts of tailings from a ... -
Global plastic pollution observation system to aid policy
(Peer reviewed; Journal article, 2021)Plastic pollution has become one of the most pressing environmental challenges and has received commensurate widespread attention. Although it is a top priority for policymakers and scientists alike, the knowledge required ... -
Future trajectories of change for an Arctic deep-sea ecosystem connected to coastal kelp forests
(Peer reviewed; Journal article, 2021)Environmental stressors related to climate change and other anthropogenic activities are impacting Arctic marine ecosystems at exceptional rates. Within this context, predicting future scenarios of deep-sea ecosystems and ... -
Using correlative and mechanistic niche models to assess the sensitivity of the Antarctic echinoid Sterechinus neumayeri to climate change
(Peer reviewed; Journal article, 2021)The Southern Ocean is undergoing rapid environmental changes that are likely to have a profound impact on marine life, as organisms are adapted to sub-zero temperatures and display specific adaptations to polar conditions. ... -
Lysates of Methylococcus capsulatus Bath induce a lean-like microbiota, intestinal FoxP3+RORγt+IL-17+ Tregs and improve metabolism
(Peer reviewed; Journal article, 2021)Interactions between host and gut microbial communities are modulated by diets and play pivotal roles in immunological homeostasis and health. We show that exchanging the protein source in a high fat, high sugar, westernized ... -
Sea ice decline drives biogeographical shifts of key Calanus species in the central Arctic Ocean
(Peer reviewed; Journal article, 2021)In recent decades, the central Arctic Ocean has been experiencing dramatic decline in sea ice coverage, thickness and extent, which is expected to have a tremendous impact on all levels of Arctic marine life. Here, we ... -
Metabolic and molecular signatures of improved growth in Atlantic salmon (Salmo salar) fed surplus levels of methionine, folic acid, vitamin B6 and B12 throughout smoltification.
(Peer reviewed; Journal article, 2021)A moderate surplus of the 1C nutrients methionine, folic acid, vitamin B6 and B12 above dietary recommendations for Atlantic salmon has shown to improve growth and reduce hepatosomatic index in the on-growing salt water ... -
Small-scale on-site treatment of fecal matter: comparison of treatments for resource recovery and sanitization
(Peer reviewed; Journal article, 2021)On-site small-scale sanitation is common in rural areas and areas without infrastructure, but the treatment of the collected fecal matter can be inefficient and is seldom directed to resource recovery. The aim of this study ... -
Antarctic krill Euphausia superba: spatial distribution, abundance, and management of fisheries in a changing climate
(Peer reviewed; Journal article, 2021)Antarctic krill Euphausia superba, a keystone species in the Southern Ocean, is highly relevant for studying effects of climate-related shifts on management systems. Krill provides a key link between primary producers and ... -
Effects of ploidy and salmonid alphavirus infection on the skin and gill microbiome of Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)The microbial communities that live in symbiosis with the mucosal surfaces of animals provide the host with defense strategies against pathogens. These microbial communities are largely shaped by the environment and the ... -
Methane cycling within sea ice: Results from drifting ice during late spring, north of Svalbard
(Peer reviewed; Journal article, 2021)Summer sea ice cover in the Arctic Ocean has declined sharply during the last decades, leading to changes in ice structures. The shift from thicker multi-year ice to thinner first-year ice changes the methane storage ... -
RNA sequencing and proteomic profiling reveal different alterations by dietary methylmercury in the hippocampal transcriptome and proteome in BALB/c mice
(Peer reviewed; Journal article, 2021)Methylmercury (MeHg) is a highly neurotoxic form of mercury (Hg) present in seafood. Here, we recorded and compared proteomic and transcriptomic changes in hippocampus of male BALB/c mice exposed to two doses of MeHg. Mice ... -
Differences in metabolic rate between two Atlantic cod (Gadus morhua) populations estimated with carbon isotopic composition in otoliths
(Peer reviewed; Journal article, 2021)The isotopic composition of inorganic carbon in otoliths (δ13Coto) can be a useful tracer of metabolic rates and a method to study ecophysiology in wild fish. We evaluated environmental and physiological sources of δ13Coto ...
