Hydropower-induced selection of behavioural traits in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Renewable energy projects such as hydropower facilities contribute towards meeting the world`s growing energy demands and urgent need for mitigating climate change. However, such infrastructure has the potential to ... -
Toxicity assessment of urban marine sediments from Western Norway using a battery of stress-activated receptors and cell-based bioassays from fish
(Peer reviewed; Journal article, 2021)A luciferase reporter gene-based bioassay battery consisting of stress-activated receptors from fish, complemented with traditional fish cell-based bioassays, were used to assess the toxicity of marine sediment samples ... -
Five centuries of cod catches in Eastern Canada
(Peer reviewed; Journal article, 2021)The fishery for Northern Atlantic cod (Gadus morhua) off Newfoundland and Labrador, Eastern Canada, presents the most spectacular case of an exploited stock crashed in a few decades by an industrial bottom trawl fishery ... -
A tidally driven fjord-like strait close to an amphidromic region
(Peer reviewed; Journal article, 2021)The strait studied in this paper, “Sundalagið Norður”, is the northern part of a narrow body of seawater separating the two largest islands in the Faroe Islands (Faroes). It has shallow sills in both ends and considerably ... -
Pathological findings in bycaught harbour porpoises (Phocoena phocoena) from the coast of Northern Norway
(Peer reviewed; Journal article, 2021)Due to little prior knowledge, the present study aims to investigate the health status of bycaught harbour porpoises from the northernmost Arctic Norwegian coastline. Gross, histopathological and parasitological investigations ... -
Gene expression and epigenetic responses of the marine Cladoceran, Evadne nordmanni, and the copepod, Acartia clausi, to elevated CO2
(Peer reviewed; Journal article, 2021)Characterizing the capacity of marine organisms to adapt to climate change related drivers (e.g., pCO2 and temperature), and the possible rate of this adaptation, is required to assess their resilience (or lack thereof) ... -
Challenges Ahead for a Rational Analysis of Vitamin D in Athletes
(Peer reviewed; Journal article, 2021)Vitamin D is an essential vitamin for the normal formation of bones and calcium absorption. It is synthesized into our body through sunlight exposure and obtained by consuming foods rich in vitamin D (e.g., fatty fish, ... -
Feeding at the front line: Interannual variation in the use of glacier fronts by foraging black-legged kittiwakes
(Peer reviewed; Journal article, 2021)Tidewater glacier fronts can represent important foraging areas for Arctic predators. Their ecological importance is likely to change in a warmer Arctic. Their profitability and use by consumers are expected to vary in ... -
Microbiological food safety of seaweeds
(Peer reviewed; Journal article, 2021)The use of seaweeds in the human diet has a long history in Asia and has now been increasing also in the western world. Concurrent with this trend, there is a corresponding increase in cultivation and harvesting for ... -
Physical and nutrient stimuli differentially modulate gut motility patterns, gut transit rate, and transcriptome in an agastric fish, the ballan wrasse
(Peer reviewed; Journal article, 2021)The effects of nutrient and mechanical sensing on gut motility and intestinal metabolism in lower vertebrates remains largely unknown. Here we present the transcriptome response to luminal stimulation by nutrients and an ... -
A deep learning-based method to identify and count pelagic and mesopelagic fishes from trawl camera images
(Peer reviewed; Journal article, 2021)Fish counts and species information can be obtained from images taken within trawls, which enables trawl surveys to operate without extracting fish from their habitat, yields distribution data at fine scale for better ... -
Automatic interpretation of salmon scales using deep learning
(Peer reviewed; Journal article, 2021)For several fish species, age and other important biological information is manually inferred from visual scrutinization of scales, and reliable automatic methods are not widely available. Here, we apply Convolutional ... -
Discerning the Management-Relevant Ecology and Distribution of Sea Pens (Cnidaria: Pennatulacea) in Norway and Beyond
(Peer reviewed; Journal article, 2021)Sea pens are considered to be of conservation relevance according to multiple international legislations and agreements. Consequently, any information about their ecology and distribution should be of use to management ... -
Sentinels in Salmon Aquaculture: Heart Rates Across Seasons and During Crowding Events
(Peer reviewed; Journal article, 2021)Advances in tag technology now make it possible to monitor the behavior of small groups of individual fish as bioindicators of population wellbeing in commercial aquaculture settings. For example, tags may detect unusual ... -
Trends in marine survival of Atlantic salmon populations in eastern Canada
(Peer reviewed; Journal article, 2021)Declines in wild Atlantic salmon (Salmo salar) abundance throughout the north Atlantic are primarily attributed to decreases in survival at sea. However, comparing trends in marine survival among populations is challenging ... -
Ocean acidification state variability of the Atlantic Arctic Ocean around northern Svalbard
(Peer reviewed; Journal article, 2021)The Svalbard shelf and Atlantic Arctic Ocean are a transition zone between northward flowing Atlantic Water and ice-covered waters of the Arctic. Effects of regional ocean warming, sea ice loss and greater influence of ... -
Ontogeny-Specific Skeletal Deformities in Atlantic Haddock Caused by Larval Oil Exposure
(Peer reviewed; Journal article, 2021)Bone deformities are one of the main effects of crude oil exposure in marine fish larvae. Craniofacial and jaw deformities, if severe enough, may restrict feeding and ultimately kill the developing larvae. This study aimed ... -
Where and How the East Madagascar Current Retroflection Originates?
(Peer reviewed; Journal article, 2021)The East Madagascar Current (EMC) is one of the western boundary currents of the South Indian Ocean. As such, it plays an important role in the climate system by transporting water and heat toward the pole and recirculating ... -
Full production cycle, commercial scale culture of salmon in submerged sea-cages with air domes reduces lice infestation, but creates production and welfare challenges
(Peer reviewed; Journal article, 2021)Structural modification of sea cages is continually changing to counter major production issues associated with commercial salmon farming. For example, snorkels and skirts are added to cages to reduce salmon lice infestations, ... -
The effect of fasting period on swimming performance, blood parameters and stress recovery in Atlantic salmon post molts
(Peer reviewed; Journal article, 2021)Individually tagged Atlantic salmon postsmolts (≈1200 g, 46 cm) reared in triplicate indoor holding tanks were fasted for 8 weeks at 12 °C and subsequently refed for 5 weeks, whereafter they were transferred to triplicate ...
