Effects of salmon lice Lepeophtheirus salmonis onwild sea trout Salmo trutta—a literature review
(Journal article; Peer reviewed, 2015-08-20)Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, ... -
Effects of seafood consumption on mercury exposure in Norwegian pregnant women: a randomized controlled trial
(Peer reviewed; Journal article, 2020)Seafood provides nutrients that are important for optimal development of the unborn child. However, seafood is also a source of contaminants including mercury (Hg) and methylmercury (MeHg) that may have adverse effects on ... -
The effects of selective harvest on Japanese Spanish mackerel (Scomberomorus niphonius) phenotypic evolution
(Peer reviewed; Journal article, 2022)Japanese Spanish mackerel (Scomberomorus niphonius) is an important fish species in the China Seas with wide distribution, extensive migration, and high economic value. This species has been yielding high fisheries production ... -
Effects of sound from seismic surveys on fish reproduction, the management case from Norway
(Peer reviewed; Journal article, 2021)Anthropogenic noise has been recognized as a source of concern since the beginning of the 1940s and is receiving increasingly more attention. While international focus has been on the effects of noise on marine mammals, ... -
The effects of spatial and temporal variations in spawning on offspring survival in Northeast Arctic cod
(Peer reviewed; Journal article, 2023)Climate change and harvesting result in temporal and spatial changes and variability in spawning, and thus in offspring ambient drift conditions. As a result, variable survival of offspring and thereby in recruitment are ... -
Effects of step salinity gradients on salmon lice larvae behaviour and dispersal
(Peer reviewed; Journal article, 2019)In trying to deal with the problematic salmon louse Lepeophtheirus salmonis in salmon aquaculture, strategies to better prevent infestations are gaining traction. Successful prevention requires an accurate understanding ... -
Effects of stunning methods on pre rigor changes in rainbow trout (Oncorhynchus mykiss) reared at two different temperatures
(Peer reviewed; Journal article, 2020)The effects of two stunning methods (carbon monoxide asphyxia, CO, and electroshock, E) on blood plasma parameters, rigor index, fillet pH and shape changes, ATP breakdown and Adenylate Energy Charge (AEC) in muscle ... -
Effects of temperature and feeding regime on cortisol concentrations in scales of Atlantic salmon post-smolts
(Peer reviewed; Journal article, 2023)Anadromous fish are vulnerable to anthropogenic and environmental stressors including pollution, rising temperatures, and changes in food availability. Knowledge of how fish respond to specific stressors aid our understanding ... -
Effects of temperature on tissue-diet isotopic spacing of nitrogen and carbon in otolith organic matter
(Journal article; Peer reviewed, 2019)Reconstruction of the trophic position of a fish can be performed by analysing stable nitrogen and carbon isotopes in otolith protein. However, ambient temperature may affect the tissue–diet isotopic spacing of stable ... -
Effects of the dietary supplementation of copper on growth, oxidative stress, fatty acid profile and skeletal development in gilthead seabream (Sparus aurata) larvae
(Peer reviewed; Journal article, 2023)The effect of dietary copper (Cu) levels on growth, oxidative stress, fatty acid profile and bone health of gilthead seabream larvae (Sparus aurata) was studied in 47 days-post-hatching fish fed 4 experimental diets ... -
Effects of the electromagnetic field used in hydrocarbon surveys on marine organisms
(Rapport fra havforskningen;2022 - 23, Research report, 2022)Controlled Source Electromagnetics (CSEM) technology has been used in the exploration for hydrocarbon reservoirs. It consists of an electric dipole source which is towed horizontally 30-50 m above the seabed or 10 m below ... -
Effects of vitamin D3 supplementation in gilthead seabream (Sparus aurata) juveniles fed diets high in plant based feedstuffs
(Peer reviewed; Journal article, 2021)Modern aquaculture feeds tend to contain lower levels of fish based ingredients, while increasing the content of plant ingredients. However, this may alter the vitamin profile of the feeds, leading to unbalanced vitamin ... -

Effects on individual level behaviour in mackerel (Scomber scombrus) of sub-lethal capture related stressors: Crowding and hypoxia
(Journal article; Peer reviewed, 2019)Stress to fish during harvest in wild capture fisheries is known to negatively influence subsequent survival in catches that are released. Therefore, if fisheries are to be conducted sustainably, there is a need to promote ... -
Effects on schooling function in mackerel of sub-lethal capture related stressors: Crowding and hypoxia
(Journal article; Peer reviewed, 2017)The selectivity of fishing gears with respect to fish species and size is important, both for fisheries management and fishing operations. Purse seining is an efficient, environmentally friendly fish capture methodology ... -
