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 ... -
Undersøkelse av grunnstoffer i sjømat fra Repparfjorden og Revsbotn - Hyse som indikatorart for overvåking av sjødeponi
(Rapport fra havforskningen;2021 - 50, Research report, 2021)Miljømyndighetene har gitt tillatelse til å benytte Repparfjorden som sjødeponi for gruveavfall (avgang). For å beskytte konsumenter av sjømat og verne om økosystemet, er det derfor ønskelig å overvåke sjømatsarter fra ... -
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 ... -
Listeria monocytogenes in salmonid slaughter facilities - Screening program for the Norwegian Food Safety Authority
(Rapport fra havforskningen;2021 - 45, Research report, 2021)Listeria monocytogenes is a bacterium of special concern in the seafood industry beacuse it possesses several properties adapted for the food production environment and may cause severe disease in humans. The Institute of ... -
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 ... -
Antibacterial treatment of lumpfish (Cyclopterus lumpus) experimentally challenged with Vibrio anguillarum, atypical Aeromonas salmonicida and Pasteurella atlantica
(Peer reviewed; Journal article, 2021)Lumpfish is a novel farmed species used as cleaner fish for the removal of lice from farmed salmon. As often with new, farmed species, there are challenges with bacterial infections. The frequency of prescription of ... -
