A transcriptomic analysis of diploid and triploid Atlantic salmon lenses with and without cataracts
(Peer reviewed; Journal article, 2020)To avoid negative environmental impacts of escapees and potential inter-breeding with wild populations, the Atlantic salmon farming industry has and continues to extensively test triploid fish that are sterile. However, ... -
Transcriptomic and targeted immune transcript analyses confirm localized skin immune responses in Atlantic salmon towards the salmon louse
(Peer reviewed; Journal article, 2023)Atlantic salmon (Salmo salar) are highly susceptible to infestations with the ectoparasite Lepeophtheirus salmonis, the salmon louse. Infestations elicit an immune response in the fish, but the response does not lead to ... -
Transcriptomic comparison of communally reared wild, domesticated and hybrid Atlantic salmon fry under stress and control conditions
(Peer reviewed; Journal article, 2020)Domestication is the process by which organisms become adapted to the human-controlled environment. Since the selection pressures that act upon cultured and natural populations differ, adaptations that favour life in the ... -
Transcriptomic responses to environmental change in fishes: Insights from RNA sequencing
(Journal article, 2017)The need to better understand how plasticity and evolution affect organismal responses to environmental variability is paramount in the face of global climate change. The potential for using RNA sequencing (RNA-seq) to ... -
Transforming sustainable aquaculture by applying circularity principles
(Peer reviewed; Journal article, 2023)A circular economy is considered one way to reduce environmental impacts of human activities, by more efficient use of resources and recovery, resulting in less waste and emissions compared to linear take-make-dispose ... -
Transmission of infectious salmon anaemia (ISA) through natural secretions and excretions from infected smolts of Atlantic salmon Salmo salar during their presymptomatic phase
(Journal article; Peer reviewed, 1996-07-18)Short-term (48 h) exposure of healthy Atlantic salmon Salmo salar L. smelts to infectious salmon anemia (ISA)-inoculated cohort smelts showed that the disease was transmitted with near 100% mortality from Day 7 post-inoculation ... -
Transmission of sound beams through the interface between two fluids
(Journal article; Peer reviewed, 1991)In this article, results from an experiment on the transmission of a sound beam at and above critical incidence onto an interface between two fluids, which are chosen to simulate a water/sand interface, are presented. The ... -
Transmission of viral encephalopathy and retinopathy (VER) to yolk-sac larvae of the Atlantic halibut Hippoglossus hippoglossus: occurrence of nodavirus in various organs and a possible route of infection
(Journal article; Peer reviewed, 1999-05-12)The susceptibility of the Atlantic halibut Hippoglossus hippoglossus yolk-sac larvae to viral encephalopathy and retinopathy (VER) was investigated by waterborne challenge experiments with nodavirus. Transfer of VER was ... -
Transparency and communication in Norwegian and Nova Scotian Atlantic salmon aquaculture industries
(Peer reviewed; Journal article, 2022)The Atlantic salmon aquaculture industry has the potential to make a significant contribution to economic development and seafood production globally – particularly in rural and coastal communities. However, the lack of ... -
Transparent multispecies analysis: an exploration of fisheries and survey data off the Norwegian coast and Barents Sea
(ICES Marine Science Symposia, Journal article; Peer reviewed, 1991)An integrated spreadsheet system was designed to combine biomass estimates for species including commercial fish species, mammals, and various other groups off the Norwegian coast and in the Barents Sea with catch data ... -
Transportation and predation control structures the distribution of a key calanoid in the Nordic Seas
(Peer reviewed; Journal article, 2022)The largest Calanus species in the Nordic Seas is also the copepod for which we have the poorest knowledge. Recent studies have shown that C. hyperboreus is more likely of sub-Arctic rather than Arctic origins, and the ... -
Travel Tales of a Worldwide Weed: Genomic Signatures of Plantago major L. Reveal Distinct Genotypic Groups With Links to Colonial Trade Routes
(Peer reviewed; Journal article, 2022)Retracing pathways of historical species introductions is fundamental to understanding the factors involved in the successful colonization and spread, centuries after a species’ establishment in an introduced range. Numerous ... -

trec: An R package for trend estimation and classification to support integrated ecosystem assessment of the marine ecosystem and environmental factors
(Peer reviewed; Journal article, 2023)Solvang and Planque [ICES Journal of Marine Science, 77, pp.2529–2540, (2020)] provided a trend estimation and classification (TREC) approach to estimating dominant common trends among multivariate time series observations. ... -
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 ... -
Triploid (sterile) farmed Atlantic salmon males attempt to spawn with wild females
(Journal article; Peer reviewed, 2014-06-18)Genetic interaction between farmed escapees and wild conspecifics represents one of the major environmental challenges faced by the Atlantic salmon aquaculture industry. In order to mitigate genetic interactions, triploid ... -
Triploid Atlantic salmon and triploid Atlantic salmon × brown trout hybrids have better freshwater and early seawater growth than diploid counterparts
(Peer reviewed; Journal article, 2021)The use of reproductively sterile triploid salmonids would enhance the environmental sustainability of the aquaculture industry by preventing genetic exchange between escapees and wild conspecifics. To this end, we assessed ... -
Triploid Atlantic salmon Salmo salar have a higher dietary phosphorus requirement for bone mineralization during early development
(Peer reviewed; Journal article, 2020)The effect of a dietary phosphorus regime in freshwater on vertebra bone mineralization was assessed in diploid and triploid Atlantic salmon, Salmo salar. Fish were fed either a low phosphorus (LP) diet containing 10.5 ... -
Triploid Atlantic salmon × brown trout hybrids have similar seawater growth and welfare issues as triploid Atlantic salmon, but both were heavier at harvest than their diploid counterparts
(Peer reviewed; Journal article, 2022)Interspecific hybridisation may improve the farm performance of sterile triploid salmonids via heterosis (i.e. hybrid vigour). We assessed growth over the final 293 days in seawater, and harvest quality, in diploid and ...
