Antarctic krill (Euphausia superba) exhibit positive phototaxis to white LED light
(Peer reviewed; Journal article, 2021)The use of light-emitting diodes (LEDs) is increasingly used in fishing gears and its application is known to trigger negative or positive phototaxis (i.e., swimming away or toward the light source, respectively) for some ... -
Antarctic krill and ecosystem monitoring survey at South Orkney Islands in 2016
(Rapport fra havforskningen;20-2016, Research report, 2016)Small scaled Russian exploratory fishing for krill in the Southern Ocean began in the late 1960s. During the 1970s the fisheries increased and annual catches of krill have exhibited a number of fluctuations since the ... -

Antarctic krill and ecosystem monitoring survey off the South Orkney Islands in 2023
(Toktrapport;2023 - 8, Research report, 2023)Environmental monitoring along 5 set transect lines off South Orkney Islands in the Southern Ocean have been carried out annually (since 2011) by the Institute of Marine Research, Norway. Data are used to calculate biomass ... -
Antarctic krill and ecosystem monitoring survey off the South Orkney Islands in 2024
(Toktrapport;2024 - 14, Research report, 2024)Environmental monitoring along 5 set transects off South Orkney Islands in the Southern Ocean have been carried out annually (since 2011) by the Institute of Marine Research, Norway. Hydro-acoustic as well as net derived ... -
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 ... -
Anthropogenic and natural size-related selection act in concert during brown trout (Salmo trutta) smolt river descent
(Peer reviewed; Journal article, 2020)By hindering migration and inducing direct turbine mortality during downstream migration, hydropower is regarded as one of the most serious threats to anadromous salmonids. Yet, little attention has been paid to long-term ... -
Anti-sea lice agents in Norwegian aquaculture; surveillance, treatment trends and possible implications for food safety
(Peer reviewed; Journal article, 2020)Sea lice are a major challenge for the Norwegian aquaculture, and to cope with sea lice infections, several physical, biological and chemical treatments are applied. This study presents data on the use of anti-sea lice ... -
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 ... -
Antibiotic sensitivity screening of Klebsiella spp. and Raoultella spp. isolated from marine bivalve molluscs reveal presence of CTX-M-producing K. pneumoniae
(Peer reviewed; Journal article, 2020)Klebsiella spp. are a major cause of both nosocomial and community acquired infections, with K. pneumoniae being responsible for most human infections. Although Klebsiella spp. are present in a variety of environments, ... -

Antioxidant and osteoinductive properties of organic selenium in microdiets for gilthead seabream (Sparus aurata) larvae
(Peer reviewed; Journal article, 2024)This study investigated the effect of yeast derived selenium (Se) dietary supplementation on larval performance, whole body mineral contents, lipid peroxidation, fatty acid profiles, expression of antioxidants and bone ... -
Apparent availability of zinc, selenium and manganese as inorganic metal salts or organic forms in plant-based diets for Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2019)The composition of salmonid diets has changed from the use of mainly marine ingredients to increased use of plant ingredients, and this has an impact on the mineral content and availability. Minerals, like zinc (Zn), ... -
Apparent biogeographical trends in Alexandrium blooms for northern Europe: Â identifying links to climate change and effective adaptive actions
(Peer reviewed; Journal article, 2022)The marine dinoflagellate Alexandrium Halim represents perhaps the most significant and intensively studied genus with respect to species diversity, life history strategies, toxigenicity, biogeographical distribution, and ... -

Application of an unsupervised clustering algorithm on in situ broadband acoustic data to identify different mesopelagic target types
(Peer reviewed; Journal article, 2021)The mesopelagic zone (200–1000 m depth) contains high fish species diversity but biomass and abundances are uncertain yet essential to understand ecosystem functioning. Hull-mounted acoustic systems (usually 38 kHz) often ... -
Application of laboratory methods for understanding fish responses to black soldier fly (Hermetia illucens) based diets
(Peer reviewed; Journal article, 2022)A major challenge for development of sustainable aquafeeds is its dependence on fish meal and fish oil. Replacement with more sustainable, nutritious and safe ingredients is now a priority. Over the last years, among several ... -
