Effects of salmon lice infection on the behaviour of sea trout in the marine phase
(Journal article; Peer reviewed, 2014-07-09)Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes. Using acoustic telemetry tracking, we investigated the behaviour ... -
Functional modifications associated with gastrointestinal tract organogenesis during metamorphosis in Atlantic halibut (Hippoglossus hippoglossus)
(Journal article; Peer reviewed, 2014-02-19)Background: Flatfish metamorphosis is a hormone regulated post-embryonic developmental event that transforms a symmetric larva into an asymmetric juvenile. In altricial-gastric teleost fish, differentiation of the stomach ... -
Mortality and deformities in European lobster (Homarus gammarus) juveniles exposed to the anti-parasitic drug teflubenzuron
(Journal article; Peer reviewed, 2014-02-04)This study describes experiments carried out to examine effects of the antiparasitic drug teflubenzuron, used in delousing farmed salmon, on a non-target species, the European lobster (Homarus gammarus). Juvenile lobsters ... -
Pacific and Atlantic Lepeophtheirus salmonis (Krøyer, 1838) are allopatric subspecies: Lepeophtheirus salmonis salmonis and L. salmonis oncorhynchi subspecies novo
(Journal article; Peer reviewed, 2014-03-14)Background The salmon louse Lepeophtheirus salmonis is a parasitic copepod that infects salmonids in the Pacific and Atlantic oceans. Although considered as a single species, morphological and biological differences have ... -
Probabilistic maturation reaction norms assessed from mark- recaptures of wild fish in their natural habitat
(Journal article; Peer reviewed, 2014-04-01)Reaction norms are a valuable tool in evolutionary biology. Lately, the probabilistic maturation reaction norm approach, describing probabilities of maturing at combinations of age and body size, has been much applied for ... -
Stable isotope marking of otoliths during vaccination: a novel method for mass-marking fish
(Journal article; Peer reviewed, 2014-06-04)Tagging or marking of fishes enables the collection of population-based information for ecological research, yet few techniques enable 100% mark detection success. We tested a new mass-marking technique: otolith marking ... -
The dynamics of a metapopulation: changes in life-history traits in resident herring that co-occur with Oceanic herring during spawning
(Journal article; Peer reviewed, 2014-07-22)Different populations of Atlantic herring are regarded as forming a metapopulation, but we know little about the dynamics of the connectivity and degree of interbreeding between the populations. Based on data from three ... -
Transcriptome sequencing of Atlantic salmon (Salmo salar L.) notochord prior to development of the vertebrae provides clues to regulation of positional fate, chordoblast lineage and mineralisation
(Journal article; Peer reviewed, 2014-02-19)Background: In teleosts such as Atlantic salmon (Salmo salar L.), segmentation and subsequent mineralisation of the notochord during embryonic stages are essential for normal vertebrae formation. However, the molecular ... -
Vertical salmon lice behaviour as a response to environmental conditions and its influence on regional dispersion in a fjord system
(Journal article; Peer reviewed, 2014-06-04)The salmon louse Lepeophtheirus salmonis is a major parasite of salmon, and is able to travel between farms during its pelagic phases. We investigated the spatial dispersion of L. salmonis planktonic stages in the ...
