Effects of ration on the maturation and fecundity in captive Atlantic herring (Clupea harengus)
(Journal article; Peer reviewed, 1998)We examined the effects of amount of food on vitellogenic oocyte size and number (fecundity) between two experimental groups of Atlantic herring (Clupea harengus) kept in separate but identical compartments of a large ... -
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 ... -
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 ... -
Effects of seismic shooting on local abundance and catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 1996)To determine whether seismic exploration affected abundance or catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus), acoustic mapping and fishing trials with trawls and longlines were conducted in the ... -
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 turbulence on the predation cycle of fish larvae: comments on some of the issues
(Journal article; Peer reviewed, 1996-08-29) -
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 of water temperature on protein synthesis and protein growth in juvenile Atlantic wolffish (Anarhichas lupus)
(Journal article; Peer reviewed, 1999)The effects of water temperature (5, 8, 11, and 14°C) on the fractional rate (percent per day) of protein consumption (kr) and on white muscle and whole-body fractional rates of protein synthesis (ks), protein growth ... -

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 ...
