Development and functions of adipose tissue in Atlantic salmon
Todorcevic, Marijana (PhD Thesis;2009:42, Doctoral thesis, 2009)The trend in salmon aquaculture is to use feed with high lipid content. In current feeds, energy from lipids can comprise as much as 50% of the total energy, compared to 10% approximately 20 years ago. This change was ... -
Effects of replacing fish oil with microalgae biomass (Schizochytrium spp) as a source of n-3 LC-PUFA to Atlantic salmon (Salmo salar) on growth performance, fillet quality and fatty acid composition
Mizambwa, Hellen Edward (Master thesis, 2017)Low levels of EFA in fish feed as a result of changes in diet composition brings a need of finding a novel ingredient that will supplement Essential Fatty Acids (EFA) in fish feed. Microalgae have ability of producing ... -
Expression of genes involved in regulation of polyunsaturated fatty acid metabolism in liver of Atlantic salmon (Salmo salar) undergoing parr-smolt transformation
Yan, Yichen (Master thesis, 2016-09-07)Purposes The primary aim of this thesis was to study if differences in nutritional and environmental factors influence the regulation of n-3 LC-PUFA synthesis in liver of Atlantic salmon (big smolts) undergoing parr-smolt ... -
Fatty acid composition and gene expression in the third generation of Atlantic salmon families selected for high and low capacity of omega3 fatty acid synthesis
Xie, Jiani (Master thesis, 2017)The major aim of this thesis was to study offspring (the third generation) of Atlantic salmon selected by high and low EPA and DHA synthesis capacity (according to high and low d6dB expression level in liver) have differences ... -
Fatty acid specificity of skin phospholipid subclasses and the response to dietary reduction of EPA and DHA in Atlantic salmon ( Salmo salar)
Du, Liang (Master thesis, 2016-08-16)Abstract The different phospholipid classes play a critical role in cell membrane structure and function. Skin is the first barrier for the animal body to prevent environmental damage and are in addition to the gills also ... -
The genetics of omega-3 fatty acids in fillets of Atlantic salmon (Salmo salar L.)
Horn, Siri Storteig (Doctoral thesis, 2019)Decreasing contents of the omega-3 fatty acids EPA and DHA in farmed Atlantic salmon reduces the nutritional value for consumers and influences physiological processes in the fish. Most studies of physiological omega-3 ... -
High and low fat diets, leucine and DHA influence growth, gene expression and fatty acid composition of different tissues in Atlantic salmon (salmo salar L)
Sandli, Ida Cathrine (Master thesis, 2019)The main goal of this master thesis project was to examine how protein to lipid ratio in the diets, and DHA and leucine in combination, interact and affect the energy utilization for growth and lipid and protein deposition ... -
A study of the gene expression profiles in muscle, liver and intestine of Atlantic salmon fed different omega- 3 fatty acid levels and with red and pale fillet color
Velzi, Sina (Master thesis, 2022)The economic value of Norwegian salmon production is closely associated with various quality factors of salmon meat like red fillet. Carotenoids are the main pigment in the fish fillet which need to be added to the feed. ... -
A study of two adipose tissue depots in Atlantic salmon : with specific focus on comparing the morphological and transcriptome characteristics between visceral and subcutaneous adipocytes
Yuan, Yi (Master thesis, 2021)Adipocytes are found in different adipose tissue depots, mainly around abdominal organs (visceral adipose tissue), or under the skin (subcutaneous adipose tissue) and between muscle fibers in myosepta including belly flap. ... -
The influence of dietary n-3 fatty acid deficiency on fatty acid composition of total lipid fraction and individual phospholipid classes in erythrocytes of Atlantic salmon (Salmo salar L.)
Vukoje, Ivana (Master thesis, 2016)While global population and its demand for seafood are constantly on the rise, aquaculture is facing a significant challenge how to provide safe and nutritious fish when fish oil supplies are decreasing. More emphasis has ... -
Very-long-chain polyunsaturated fatty acids and their biological functions
Torrissen, Martina (PhD Thesis;2023:83, Doctoral thesis, 2023)The overall aim of this thesis was to gain insight into the bioavailability of dietary very-long-chain polyunsaturated fatty acids (VLC-PUFAs) and their potential effects on skin and bone health. While well-known omega-3 ...
