Acclimation with lice-infested salmon improves cleaner fish delousing performance
(Peer reviewed; Journal article, 2021)Securing the welfare and maximising the lice removal efficacy of ~60 million cleaner fish used each year on salmonid farms is essential to develop a productive and ethical industry with low salmon lice Lepeophtheirus ... -
Accumulation and toxicity of monoaromatic petroleum hydrocarbons in early life stages of cod and haddock
(Journal article; Peer reviewed, 2019)A multitude of recent studies have documented the detrimental effects of crude oil exposure on early life stages of fish, including larvae and embryos. While polycyclic aromatic hydrocarbons (PAHs), particularly alkyl PAHs, ... -
Accuracy of the Kirchhoff-approximation and Kirchhoff-ray-mode fish swimbladder acoustic scattering models
(Journal article; Peer reviewed, 2013)The acoustic backscatter from pressure release prolate spheroids and a three-dimensional representation of a fish swimbladder (Chilean jack mackerel, Trachurus symmetricus murphyi) was calculated using four target strength ... -
Achieving Reliable Estimates of the Spatial Distribution of Kelp Biomass
(Peer reviewed; Journal article, 2020)Kelp forests are highly productive systems that are important ecologically and commercially as well as in a blue carbon perspective. Given their importance, there is an urgent need to achieve reliable estimates of the ... -
Acidification of the Nordic Seas
(Peer reviewed; Journal article, 2022)Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a ... -
Acidification of the Nordic Seas
(Peer reviewed; Journal article, 2022)Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a ... -
Acoustic classification in multifrequency echosounder data using deep convolutional neural networks
(Peer reviewed; Journal article, 2020)Acoustic target classification is the process of assigning observed acoustic backscattering intensity to an acoustic category. A deep learning strategy for acoustic target classification using a convolutional network is ... -
Acoustic detection of the Greenland shark (Somniosus microcephalus) using multifrequency split beam echosounder in Svalbard waters
(Peer reviewed; Journal article, 2022)The conservation status of the long-lived Greenland shark (Somniosus microcephalus) is unknown, and methods for non-invasively estimating local or regional abundances are wanted. Using a multifrequency split beam echosounder ... -
Acoustic manual for the krill synoptic survey in 2019
(CCAMLR;WG-EMM-18/12, Research report, 2018)The previously presented document at the 2018 ASAM WG meeting (ASAM-18-07) described a design and plans for a synoptic krill acoustic survey in CCAMLR area 48 in 2019. The survey involves the collaborative efforts of Norway, ... -
Acoustic micronektonic distribution and density is structured by macroscale oceanographic processes across 17–48° N latitudes in the North Atlantic Ocean
(Peer reviewed; Journal article, 2023)This study investigates the large-scale distribution patterns of the acoustic scattering layers and micronekton density across the Northeast Atlantic Ocean during daylight hours. A research cruise on board R/V “Kronprins ... -
Acoustic scattering layers reveal a faunal connection across the Fram Strait
(Peer reviewed; Journal article, 2020)Acoustic scattering layers (SL) at various depths are common phenomena in most oceans, but the organisms that make up these layers vary and so does their density, and hence the backscattered energy. During two crossings ... -
The Acute and Delayed Mortality of the Northern Krill (Meganyctiphanes norvegica) When Exposed to Hydrogen Peroxide
(Peer reviewed; Journal article, 2020)Bath treatment pharmaceuticals used to control sea lice infestations in the salmonid industry, such as hydrogen peroxide (H2O2), are released directly into the environment where non-target organisms are at risk of exposure. ... -
Acute stress response on Atlantic salmon: a time-course study of the effects on plasma metabolites, mucus cortisol levels, and head kidney transcriptome profile
(Peer reviewed; Journal article, 2022)Farmed Atlantic salmon (Salmo salar) welfare and performance can be strongly influenced by stress episodes caused by handling during farming practices. To better understand the changes occurring after an acute stress ... -
Acute toxic effects of hydrogen peroxide, used for salmon lice treatment, on the survival of polychaetes (Capitella sp. and Ophryotrocha spp.)
(Journal article; Peer reviewed, 2018)The amount of hydrogen peroxide (H2O2) used in the treatment of salmon lice in Norwegian salmon farming increased from 308 tons in 2009 to 43246 tons in 2015. For 2016 and 2017, however, the consumption was reduced to 26597 ... -
'Adaptation science' is needed to inform the sustainable management of the world's oceans in the face of climate change
(Peer reviewed; Journal article, 2022)The global response to the challenge of increasingly rapid and severe climate change is shifting from a focus on mitigation and remediation of impacts to a pragmatic adaptation framework. Innovative adaptive solutions that ... -
Adaptation to Low Salinity Promotes Genomic Divergence in Atlantic Cod (Gadus morhua L.)
