The effect of hydrodynamics on benthic macrofaunal composition and functioning under salmon fish farms
(Master thesis, 2015-08-17)The fish farming industry has continued to increase over the last years, and salmon fish farms in Norway continue to grow in numbers. With this growing aquaculture, there is also a larger need to quantify the environmental ... -
Effect of increased rearing temperature on digestive function in cobia early juvenile
(Peer reviewed; Journal article, 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 ... -
Effect of initial biomass-specific photon supply rate on fatty acid accumulation in nitrogen depleted Nannochloropsis gaditana under simulated outdoor light conditions
(Peer reviewed; Journal article, 2018-11)Triacylglycerol (TAG) accumulation in the microalgae Nannochloropsis gaditana is induced by nitrogen starvation and dependent on the light supplied. We studied under simulated outdoor light conditions the effect of supplied ... -
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
(Peer reviewed; Journal article, 2019-10-15)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 ... -
The effect of low temperatures and photoperiods on growth in Atlantic salmon (Salmo salar)
(Master thesis, 2015-07-01)This thesis examines the growth response of Atlantic salmon post-smolt (Salmo salar) in a factorial experiment with three temperatures and two light regimes. The aim of this study was to investigate under laboratory ... -
The effect of nutritional condition by two nucleic acid derived indices on the growth to post-flexion of Atlantic bluefin tuna and Atlantic bonito larvae
(Peer reviewed; Journal article, 2019)Notochord flexion increases the swimming capacity of fish larvae, aids in the capture of mobile prey, and coincides with the timing of when the physiological capacities of larvae begin to develop significantly, allowing ... -
Effect of Photoperiod and Transfer Time on Atlantic Salmon Smolt Quality and Growth in Freshwater and Seawater Aquaculture Systems
(Journal article; Peer reviewed, 2023)Smoltification is a key process in Atlantic salmon aquaculture, given it prepares the fish for a successful transit from fresh to seawater. However, industry players have not yet reached a consensus on the best protocols ... -
The effect of photoperiod manipulation on Atlantic salmon growth, smoltification and sexual maturation: A case study of a commercial RAS
(Journal article; Peer reviewed, 2021)The effect of photoperiod manipulation on growth, smoltification and maturation was assessed in Atlantic salmon through an observational study performed in a commercial RAS facility from June (25.0 ± 11.0 g) to October ... -
The effect of plant proteins and vegetable oils on the sterol metabolism of Atlantic salmon (salmo salar)
(Master thesis, 2011-05-27)To ensure responsible use of the valuable marine ingredients a major effort is being invested in understanding effects of replacing fish meal and fish oil partially or completely with plant proteins and vegetable oils in ... -
The effect of pot design on behaviour and catch efficiency of gadoids
(Master thesis, 2015-05-29)The behavioural response of fish to pots is poorly understood but is a vital component of the fish capture process. Here, the behaviour of gadoids prior to and after capture in different baited fish pot designs was observed ... -
Effect of rearing temperature on flesh quality in Arctic charr (Salvelinus alpinus)
(Journal article; Peer reviewed, 2021)Currently, no information is available on the effect of progressively decreasing temperatures on the sensory quality of Arctic charr. The objective of this study was to investigate if and how different and progressively ... -
Effect of removal of bacteria on the biomass and extracellular carbohydrate productivity of Botryococcus braunii
(Peer reviewed; Journal article, 2019)Botryococcus braunii CCALA778 is a green microalga that can produce large amounts of extracellular carbohydrates and therefore is a potential host for industrial applications such as materials, food and pharmaceutical ... -
Effect of tag weight on vertical behavior of Atlantic salmon (Salmo salar) smolts: an overlooked tag effect?
(Master thesis, 2021-06-01) -
The effect of temperature on ability of Lepeophtheirus salmonis to infect and persist on Atlantic salmon
(Journal article; Peer reviewed, 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 ... -
The effect of temperature on growth performance and aerobic metabolic scope in Arctic charr, Salvelinus alpinus (L.)
(Journal article; Peer reviewed, 2022)In recent years, Arctic char populations in Iceland have declined and the objective of this experiment was to throw further light on these changes by examining the effect of temperature (5, 9, 13, 17, and 21 °C) on the ... -
The effect of the COVID-19 pandemic on the gender gap in research productivity within academia
(Journal article; Peer reviewed, 2023)Using measures of research productivity to assess academic performance puts women at a disadvantage because gender roles and unconscious biases, operating both at home and in academia, can affect research productivity. The ... -
Effect of tryptophan enriched diets on aggression in hierarchical groups of juvenile Atlantic salmon (Salmo salar)
(Master thesis, 2010-07-01)Aggression in fish hierarchies often leads to one dominant individual monopolizing resources (food/shelter), thus increasing their fitness. Meanwhile individuals in subordinate ranks, endure high stressful conditions, which ... -
Effect of uneven sampling along an environmental gradient on transfer-function performance
(Peer reviewed; Journal article, 2011-04-27)We investigate the effect that uneven sampling of the environmental gradient has on transfer-function performance using simulated community data. We find that cross-validated estimates of the root mean squared error of ... -
The effect of water currents on post-smolt Atlantic salmon, Salmo salar (L.). A welfare approach to exposed aquaculture
(Doctoral thesis, 2017-06-27)The future development of Atlantic salmon (Salmo salar L.) aquaculture is limited by the availability of space and suitable environments along coastal areas. Utilising exposed areas is a possible solution to this problem. ...
