Effect of increased rearing temperature on digestive function in cobia early juvenile
(Journal article; Peer reviewed, 2019)The present study is focused to elucidate the main characteristics of the digestive function of this carnivorous fast-growing fish living at high temperatures. With this aim, we have examined the effects of an increased ... -
The effect of interannual variation in growth and condition on haddock recruitment
(Journal article; Peer reviewed, 1999)The relationship between recruitment and spawner biomass assumes that estimates of spawner biomass are proportional to total egg production by the stock. The validity of this assumption is in question for long-lived ... -
Effect of levels and sources of dietary manganese on growth and mineral composition of post-smolt Atlantic salmon fed low fish meal, plant-based ingredient diets
(Journal article; Peer reviewed, 2019)The impact of dietary manganese (Mn) levels and sources on the growth and mineral composition of post-smolt Atlantic salmon (Salmo salar) fed practical diets was studied. Seven experimental diets were prepared with graded ... -
Effect of light-emitting diodes (LEDs) on snow crab catch rates in the Barents Sea pot fishery
(Journal article; Peer reviewed, 2019)Snow crab (Chionoecetes opilio) has become an important species for the Norwegian seafood industry since its first commercial harvest in 2012. However, periodically catch rates can be low, causing a financial strain on the ... -
Effect of Mytilus coruscus selective filtration on phytoplankton assemblages
(Peer reviewed; Journal article, 2022)The feeding selectivity of bivalves can play an important role in shaping the structure of phytoplankton communities of natural waters. This could be particularly true in waters with intensive bivalves farming, like Sungo ... -
The effect of recent changes in the North Sea mackerel fishery on stock and yield
(Journal article; Peer reviewed, 1978)The paper deals with biological aspects and exploitation of the mackerel (Scomber scombrus) stocks occurring in the North Sea. The state of stocks and exploitation in the North Sea area are investigated on the basis of ... -
Effect of sea lice chemotherapeutant hydrogen peroxide on the photosynthetic characteristics and bleaching of the coralline alga Lithothamnion soriferum
(Peer reviewed; Journal article, 2022)The proliferation of sea lice (Lepeophtheirus salmonis) represents a major challenge for the salmonid aquaculture industry in Norway. Hydrogen peroxide (H2O2) is a chemotherapeutant frequently used on Norwegian farms, ... -
Effect of solar ultraviolet radiation (280–400 nm) on the eggs and larvae of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 1999)In the Gulf of St. Lawrence, Canada, solar ultraviolet B radiation (UV-B, 280–320 nm) penetrates a significant percentage of the summer mixed-layer water column: organisms residing in this layer, such as the eggs of Atlantic ... -
Effect of Sub-Lethal Exposure to Ultraviolet Radiation on the Escape Performance of Atlantic Cod Larvae (Gadus morhua)
(Journal article; Peer reviewed, 2012-04-19)The amount of ultraviolet (UV) radiation reaching the earth’s surface has increased due to depletion of the ozone layer. Several studies have reported that UV radiation reduces survival of fish larvae. However, indirect ... -
Effect of substrate type and pellet age on the resuspension of Atlantic salmon faecal material
(Peer reviewed; Journal article, 2020) -
Effect of suspended sediments on the pumping rates of three species of glass sponge in situ
(Journal article; Peer reviewed, 2019)The largest known glass sponge reefs in Canada are within the Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area (HSQCS-MPA) in British Columbia. However, human activities outside the core MPA ... -
The effect of temperature on ability of Lepeophtheirus salmonis to infect and persist on Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)The salmon louse (Lepeophtheirus salmonis) is an ecologically and economically important parasite of salmonid fish. Temperature is a strong influencer of biological processes in salmon lice, with development rate increased ... -
Effect of temperature on the metabolism, behaviourand oxygen requirements of Sparus aurata
(Journal article; Peer reviewed, 2015-09-03)We investigated the effect of temperature on the limiting oxygen saturation (LOS) of gilthead sea bream Sparus aurata. This threshold was defined as the % O2 saturation where fish no longer upheld their routine metabolic ... -
The effect of temperature on the survival of salmonid alphavirus analysed using in vitro and in vivo methods
(Peer reviewed; Journal article, 2020)Disease outbreaks in fish aquaculture are often of concern due to the possibility of pathogen transmission to fish in neighbouring farms and to wild fish populations. To be able to assess the risk and manage transmission ... -
The Effect of the Meat Factor in Animal-Source Foods on Micronutrient Absorption: A Scoping Review
(Peer reviewed; Journal article, 2022)The EAT-Lancet Commission's planetary health guidelines suggest a reduction in the consumption of animal-source foods (ASFs) for better health and more sustainable food systems. ASFs are highly nutrient dense, therefore ... -
Effect of the Nordmøre grid bar spacing on size selectivity, catch efficiency and bycatch of the Barents Sea Northern shrimp fishery
(Peer reviewed; Journal article, 2022)The introduction of the Nordmøre grid in shrimp trawls has reduced the bycatch of non-target species. In the Norwegian Northern shrimp (Pandalus borealis) fishery, the mandatory selective gear consists of a Nordmøre grid ... -
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 ... -
Effect of water temperature and exposure duration on detachment rate of salmon lice (Lepeophtheirus salmonis); testing the relevant thermal spectrum used for delousing
(Peer reviewed; Journal article, 2023)Thermal delousing has become the most applied method for treatment against salmon lice. However, the temperature range used is strongly aversive for salmonids, and the method is associated with increased mortality. Treatment ... -
