Effect of turbulence on the energetics of foraging in Atlantic cod Gadus morhua larvae
(Journal article; Peer reviewed, 2004-11-01)A net energy gain (NEG) model was used to assess the effects of turbulence on the energy budget of Atlantic cod Gadus morhua larvae, feeding on copepod nauplii at different concentrations. The geometry of their prey search ... -
An effective method for the recapture of escaped farmed salmon
(Journal article; Peer reviewed, 2011-04-04)The search for effective strategies to prevent and mitigate accidental releases of aquaculture fishes is on-going. To test a new recapture strategy and evaluate the individual dispersal behaviour of escaped farmed Atlantic ... -
Efficacy of florfenicol in the treatment of bacterial infections in halibut, Hippoglossus hippoglossus (L.), larvae
(Journal article; Peer reviewed, 2011-10-17) -
Efficacy of Orally Administered Florfenicol in the Treatment of Furunculosis in Atlantic Salmon
(Journal article; Peer reviewed, 1998)This study was performed to determine the efficacy of orally administered florfenicol to treat experimentally induced furunculosis in Atlantic salmon Salmo salar held in seawater. A strain of the causative bacterium, ... -
Efficacy of orally administered flumequine in the treatment of vibriosis caused by Listonella anguillarum in Atlantic cod Gadus morhua
(Journal article; Peer reviewed, 2005-11-09)The efficacy of orally administered flumequine in the treatment of experimentally induced vibriosis in Atlantic cod Gadus morhua was investigated. Cod (mean ± SD, 120 ± 30 g) were randomly distributed to twelve tanks and ... -
Environmental drivers of Atlantic salmon behaviour in sea-cages: a review
(Journal article; Peer reviewed, 2011-02-03)Salmon may sense and respond to a range of environmental variables within sea-cages, including light, temperature, salinity, dissolved oxygen, water currents and certain chemical treatments used during production. Environments ... -
Environmental regulation of individual depth on a cod spawning ground
(Journal article; Peer reviewed, 2012-12-13)Fine-scale characteristics of spawning grounds may provide the opportunity for cod Gadus morhua L. to regulate their external environment by adjusting their depth. Ultrasonic telemetry was used to study how the environment ... -
EST resources and establishment and validation of a 16 k cDNA microarray from Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2010-06-28)The Atlantic cod, Gadus morhua, is an important species both for traditional fishery and increasingly also in fish farming. The Atlantic cod is also under potential threat from various environmental changes such as pollution ... -
Establishment of new wintering areas in herring co-occurs with peaks in the ‘first time/repeat spawner’ ratio
(Journal article; Peer reviewed, 2010-06-23)Norwegian spring spawning (NSS) herring migrate to wintering areas in late summer and remain there for about 5 mo in dense aggregations. First-time spawning cohorts typically adopt the wintering area of the spawning stock. ... -
Evaluating bioencapsulation of florfenicol in rotifers (Brachionus plicatilis)
(Journal article; Peer reviewed, 2010-11-11)The rotifer Brachionus plicatilis is one of the most important live-feed organisms used in the larval culture of marine fish. Bioencapsulation of florfenicol in rotifers was investigated by delivering it directly to the ... -
Evaluation of emamectin benzoate and substance EX against salmon lice in sea-ranched Atlantic salmon smolts
(Journal article; Peer reviewed, 2015-04-08)Experimental releases of Atlantic salmon smolts treated with emamectin benzoate (EB) against salmon lice have previously been used to estimate the significance of salmon lice on the survival of migrating smolts. In recent ... -
Exploration and learning of demand-feeding in Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2010-08-15)A bite–and–pull demand–feeding system was introduced to groups of cultured cod (Gadus morhua). For half of the groups trigger actuations were rewarded with food, while actuations were unrewarded in the other groups. ... -
Extension of the match-mismatch hypothesis to predator-controlled systems
(Journal article; Peer reviewed, 2013-01-31)Differential change in the phenology of predators and prey is a potentially important climate-mediated mechanism influencing populations. The match-mismatch hypothesis describes the effect of predator-prey population ... -
Extent and ecological importance of escape through spawning in sea-cages for Atlantic cod
(Journal article; Peer reviewed, 2012-11-14)The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ... -
Fatty acids in harp seal blubber do not necessarily reflect their diet
(Journal article; Peer reviewed, 2011-03-28)The predator–prey relationship with respect to fatty acids (FAs) was studied in 57 harp seals Pagophilus groenlandicus and 16 potential prey species collected simultaneously in the northwestern Barents Sea in May–June 2006. ... -
Feeding Ecology of Coryphaenoides rupestris from the Mid-Atlantic Ridge
(Journal article; Peer reviewed, 2010-05-03)The Macrourid fish roundnose grenadier, Coryphaenoides rupestris, is one of the most common benthopelagic fishes on the northern mid-Atlantic Ridge. The ecology of the species is comparatively well studied in continental ... -
Feeding of mature cod (Gadus morhua) on the spawning grounds in Lofoten
(Journal article; Peer reviewed, 2008-03-19)Many authors state that cod (Gadus morhua) do not feed during the spawning period. However, this more or less established fact has rarely been investigated in the field. Here, the content of stomachs from Northeast Arctic ... -
Feeding preference of recaptured Atlantic salmon Salmo salar following simulated escape from fish pens during autumn
(Journal article; Peer reviewed, 2010-12-21)Escapes of farmed fish from coastal farms around the world are believed to have genetic and ecological consequences for wild fish populations. Each year there are numerous escapes of adult farmed Atlantic salmon Salmo ... -
