Brain serotonergic activation in growth-stunted farmed salmon: Adaption versus pathology
(Journal article; Peer reviewed, 2016-05-25)Signalling systems activated under stress are highly conserved, suggesting adaptive effects of their function. Pathologies arising from continued activation of such systems may represent a mismatch between evolutionary ... -
Cleaner fish escape salmon farms and hybridize with local wrasse populations
(Journal article; Peer reviewed, 2018)The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish used to remove sea lice from farmed fish, are rarely considered. Here, we report that wild ... -
Computational animal welfare: Towards cognitive architecture models of animal sentience, emotion and wellbeing
(Peer reviewed; Journal article, 2020)To understand animal wellbeing, we need to consider subjective phenomena and sentience. This is challenging, since these properties are private and cannot be observed directly. Certain motivations, emotions and related ... -
Disentangling the effects of sex, life history and genetic background in Atlantic salmon: Growth, heart and liver under common garden conditions: Atlantic salmon: Growth, heart & liver
(Peer reviewed; Journal article, 2020)Livestock domestication has long been a part of agriculture, estimated to have first occurred approximately 10 000 years ago. Despite the plethora of traits studied, there is little understanding of the possible impacts ... -
Does density influence relative growth performance of farm, wild and F1 hybrid Atlantic salmon in semi-natural and hatchery common garden conditions?
(Journal article; Peer reviewed, 2016-07-06)The conditions encountered by Atlantic salmon, Salmo salar L., in aquaculture are markedly different from the natural environment. Typically, farmed salmon experience much higher densities than wild individuals, and may ... -
Don't mind if I do: Arctic humpback whales respond to winter foraging opportunities before migration
(Peer reviewed; Journal article, 2023)Migration patterns are fundamentally linked to the spatio-temporal distributions of prey. How migrating animals can respond to changes in their prey's distribution and abundance remains largely unclear. During the last ... -
Environmental drivers of population-level variation in the migratory and diving ontogeny of an Arctic top predator
(Peer reviewed; Journal article, 2022)The development of migratory strategies that enable juveniles to survive to sexual maturity is critical for species that exploit seasonal niches. For animals that forage via breath-hold diving, this requires a combination ... -
Evolutionary drivers of kype size in atlantic salmon (salmo salar): domestication, age and genetics
(Journal article; Peer reviewed, 2019)The diversity of reproduction and associated mating patterns in Atlantic salmon (Salmo salar) has long captivated evolutionary biologists. Salmo salar exhibit strategies involving migration, bold mating behaviours and ... -
First indications that northern bottlenose whales are sensitive to behavioural disturbance from anthropogenic noise
(Journal article; Peer reviewed, 2015-06-03)Although northern bottlenose whales were the most heavily hunted beaked whale, we have little information about this species in its remote habitat of the North Atlantic Ocean. Underwater anthropogenic noise and disruption ... -
Historical gene flow constraints in a northeastern Atlantic fish: Phylogeography of the ballan wrasse labrus bergylta across its distribution range
(Peer reviewed; Journal article, 2017) -
Inferring Atlantic salmon post-smolt migration patterns using genetic assignment
(Journal article; Peer reviewed, 2019)Understanding migratory patterns is important for predicting and mitigating unwanted consequences of environmental change or anthropogenic challenges on vulnerable species. Wild Atlantic salmon undergo challenging migrations ... -
Losing the 'arms race': Multiresistant salmon lice are dispersed throughout the North Atlantic Ocean
(Peer reviewed; Journal article, 2021)Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in ... -
Mid and hindgut transcriptome profiling analysis of Atlantic salmon (Salmon salar) under unpredictable chronic stress
(Peer reviewed; Journal article, 2020)The intestinal epithelium is a selectively permeable barrier for nutrients, electrolytes and water, while maintaining effective protection against pathogens. Combinations of stressors throughout an animal's life, especially ... -
Migratory passage structures at hydropower plants as potential physiological and behavioural selective agents
(Journal article; Peer reviewed, 2019)Anthropogenic activities affect fish populations worldwide. River dams have profound impacts on ecosystems by changing habitats and hindering migration. In an effort to counteract such effects, a range of mitigation measures ... -
The pantophysin gene and its relationship with survival in early life stages of Atlantic cod: Pantophysin in Atlantic cod
(Peer reviewed; Journal article, 2020)Genetic markers are widely used in fisheries management around the world. While the genetic structure and markers selected are usually based on samples from the wild, very few controlled experiments have been carried out ... -
Pre-fertilization gamete thermal environment influences reproductive success, unmasking opposing sex-specific responses in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2023)The environment gametes perform in just before fertilization is increasingly recognized to affect offspring fitness, yet the contributions of male and female gametes and their adaptive significance remain largely unexplored. ... -
Seasonal acoustic presence of marine mammals at the South Orkney Islands, Scotia Sea
(Peer reviewed; Journal article, 2024)Increased knowledge about marine mammal seasonal distribution and species assemblage from the South Orkney Islands waters is needed for the development of management regulations of the commercial fishery for Antarctic krill ... -
The influence of sea ice, wind speed and marine mammals on Southern Ocean ambient sound
(Journal article; Peer reviewed, 2017)This paper describes the natural variability of ambient sound in the Southern Ocean, an acoustically pristine marine mammal habitat. Over a 3-year period, two autonomous recorders were moored along the Greenwich meridian ... -
The relationship between the moon cycle and the orientation of glass eels (Anguilla anguilla) at sea
(Journal article; Peer reviewed, 2019)Links between the lunar cycle and the life cycle (migration patterns, locomotor activity, pulses in recruitment) of the European eel (Anguilla anguilla) are well documented. In this study, we hypothesized that the orientation ...
