Growth of Atlantic salmon (Salmo salar) under different regimes of continuous aerobic exercise
(Master thesis, 2023-06-02)To ensure the Atlantic salmon aquaculture industry's sustainable growth, the development and implementation of new production strategies is needed. A strategy that has been adopted by the industry to intensify the salmon’s ... -
Host specificity and clade dependent distribution of putative virulence genes in Moritella viscosa
(Peer reviewed; Journal article, 2014-12)Moritella viscosa is the aetiological agent of winter-ulcer disease in farmed salmonids in the North Atlantic. Previously, two major (typical and variant) genetic clades have been demonstrated within this bacterial species, ... -
Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar
(Peer reviewed; Journal article, 2015-02)There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains , and , respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, ... -
In vitro bacterial and viral response in head kidney leukocytes of Atlantic salmon (Salmo salar) fed dietary insects meal.
(Master thesis, 2018-06-07)With the fast growth of today’s aquaculture industry, the demand for aqua-feeds is expanding dramatically. Insects, which are part of the natural diet of salmonids, could represent a sustainable ingredient for aquaculture ... -
The influence of vgll3 genotypes on sea age at maturity is altered in farmed mowi strain Atlantic salmon
(Peer reviewed; Journal article, 2019-05-06)Background: In Atlantic salmon in the wild, age at maturity is strongly influenced by the vgll3 locus. Under farming conditions, light, temperature and feeding regimes are known significantly advance or delay age at maturity. ... -
Intensive Farming: Evolutionary Implications for Parasites and Pathogens
(Peer reviewed; Journal article, 2010)An increasing number of scientists have recently raised concerns about the threat posed by human intervention on the evolution of parasites and disease agents. New parasites (including pathogens) keep emerging and parasites ... -
Judging a salmon by its spots: Environmental variation is the primary determinant of spot patterns in Salmo salar
(Peer reviewed; Journal article, 2018-04-12)Background. In fish, morphological colour changes occur from variations in pigment concentrations and in the morphology, density, and distribution of chromatophores in the skin. However, the underlying mechanisms remain ... -
Methionine deficiency does not increase polyamine turnover through depletion of hepatic S-adenosylmethionine in juvenile Atlantic salmon
(Peer reviewed; Journal article, 2014-10)During the last few decades, plant protein ingredients such as soya proteins have replaced fishmeal in the diets of aquacultured species. This may affect the requirement and metabolism of methionine as soya contains less ... -
Multi-locus variable-number tandem-repeat analysis of the fish-pathogenic bacterium Yersinia ruckeri by multiplex PCR and capillary electrophoresis
(Peer reviewed; Journal article, 2019-06-17)Yersinia ruckeri is an important pathogen of farmed salmonids worldwide, but simple tools suitable for epizootiological investigations (infection tracing, etc.) of this bacterium have been lacking. A Multi-Locus Variable-number ... -
Multilocus variable-number tandem-repeat analysis of Yersinia ruckeri confirms the existence of host specificity, geographic endemism, and anthropogenic dissemination of virulent clones
(Peer reviewed; Journal article, 2018-08)A multilocus variable-number tandem-repeat analysis (MLVA) assay was developed for epizootiological study of the internationally significant fish pathogen Yersinia ruckeri, which causes yersiniosis in salmonids. The assay ... -
Notochord development in Atlantic salmon (Salmo salar L.): exploring molecular pathways and putative mechanism of segmentation
(Doctoral thesis, 2014-03-07)Background: A key feature of the vertebrate body plan is the repeated compartments made up of individual vertebra, blood vessels, peripheral nerves and muscle. The vertebral column comprises a series of bony vertebral ... -
The notochord in Atlantic salmon (Salmo salar L.) undergoes profound morphological and mechanical changes during development
(Peer reviewed; Journal article, 2017-11)We present the development of the notochord of the Atlantic salmon (Salmo salar L.), from early embryo to sexually mature fish. Over the salmon's lifespan, profound morphological changes occur. Cells and gross structures ... -
Ploidy elicits a whole-genome dosage effect: growth of triploid Atlantic salmon is linked to the genetic origin of the second maternal chromosome set
(Peer reviewed; Journal article, 2017-04-11)Background: The Atlantic salmon aquaculture industry is investigating the feasibility of using sterile triploids to mitigate genetic interactions with wild conspecifics, however, studies investigating diploid and triploid ... -
Potential of insect-based diets for Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2018-04)In the present study, we aimed to assess the effect of dietary insect meal (IM) and insect oil (IO) on growth performance, body composition and nutrient digestibility of freshwater reared Atlantic salmon. The IM and IO ... -
Prevalence and genotypes of infectious salmon anaemia virus (ISAV) in returning wild Atlantic salmon (Salmo salar L.) in northern Norway
(Peer reviewed; Journal article, 2019-08) -
Proof of Principle Efficacy and Safety Optimisation of Tenacibaculum Vaccine Prototypes Against Tenacibaculosis in Atlantic Salmon
(Master thesis, 2022-06-01)Mouthrot, caused by the bacterium Tenacibaculum maritimum, is a major health and welfare problem in newly sea-transferred Atlantic salmon smolts (Salmo salar) in BC, Canada, and have caused large economical losses over the ... -
Replacing fish meal with insect meal in the diet of Atlantic salmon (Salmo salar) does not impact the amount of contaminants in the feed and it lowers accumulation of arsenic in the fillet
(Peer reviewed; Journal article, 2019)Insects are promising sources of protein and lipid in feeds for farmed animals. In the European Union, the use of insect meal (IM) and insect oil is permitted in fish feed. However, the European Food Safety Authority has ... -
