Vertical migrations of a deep-sea fish and its prey
(Journal article; Peer reviewed, 2014-05-23)It has been speculated that some deep-sea fishes can display large vertical migrations and likely doing so to explore the full suite of benthopelagic food resources, especially the pelagic organisms of the deep scattering ... -
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 ... -
Veterinary drug use in United States net pen Salmon aquaculture: Implications for drug use policy
(Peer reviewed; Journal article, 2020)Aquaculture now produces nearly half of the seafood consumed globally. Atlantic salmon (Salmo salar) is one of the top aquaculture products and the most valuable farmed marine finfish species in the United States (U.S.). ... -
Vgll3 and the Hippo pathway are regulated in Sertoli cells upon entry and during puberty in Atlantic salmon testis
(Journal article; Peer reviewed, 2018)Vgll3 is linked to age at maturity in Atlantic salmon (Salmo salar). However, the molecular mechanisms involving Vgll3 in controlling timing of puberty as well as relevant tissue and cell types are currently unknown. Vgll3 ... -

(Journal article; Peer reviewed, 2005-12-30)Homogenate of tissue from juveniles of Atlantic halibut Hippoglossus hippoglossus suffering from viral encephalopathy and retinopathy (VER) was used to challenge smolt of Atlantic salmon Salmo salar with an initial average ... -
Viral Haemorrhagic Septicemia Virus (VHSV) Isolated from Atlantic Herring, Clupea harengus, Causes Mortality in Bath Challenge on Juvenile Herring
(Peer reviewed; Journal article, 2023)Viral hemorrhagic septicaemia virus (VHSV) has been demonstrated to cause high mortalities in a wide range of teleosts, farmed as well as wild. In Europe, VHSV of genotypes Ib, Id, II, and III have been detected in wild ... -
Visual predation by the euphausiid Meganyctiphanes norvegica
(Journal article; Peer reviewed, 2001-01-05)Experiments showed that Meganyctiphanes norvegica are visual predators on copepods. Adult M. norvegica were offered a mixture of equal numbers of late stage Calanus spp. and Metridia longa in total darkness and at a light ... -
Visual predation risk and spatial distributions of large Arctic copepods along gradients of sea ice and bottom depth
(Peer reviewed; Journal article, 2023)Changes in the community size structure of Arctic copepods toward smaller and less fat individuals or species have been linked to environmental changes. The underpinning mechanisms are, however, poorly understood. We use ... -
Vitality as a measure of animal welfare during purse seine pumping related crowding of Atlantic mackerel (Scomber scrombrus)
