Effect of dietary enrichment with antioxidants on the sensory quality of raw and cooked Atlantic salmon (Salmo salar L.)
(Master thesis, 2016-06-06)The main sensory quality parameters of Atlantic salmon are color, texture, fillet integrity, taste and odor. The aim of the present study was to investigate the effect of diet on sensory quality of raw salmon fillets, and ... -
Effect of dietary fat level and exercise on growth, feed utilization, nutrient digestibility and fat deposition in Atlantic salmon (Salmo salar L.)
(Master thesis, 2013-10-21)The aim of the present study was to investigate the effects of dietary fat level and exercise on growth, feed utilization, nutrient digestibility and fat deposition in farmed Atlantic salmon (Salmo salar L.). Atlantic ... -
Effects of vaccination and dietary treatment on development and melanin deposition of Atlantic salmon (Salmo salar L.)
(Master thesis, 2014-08-13)Visual appearance is an essential quality property of food products. For salmonids the red color of the flesh is a main characteristic noticed by consumers, and fillets with discolored patches are downgraded. During recent ... -
Fatty acid specificity of skin phospholipid subclasses and the response to dietary reduction of EPA and DHA in Atlantic salmon ( Salmo salar)
(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 ... -
Fillet quality and yield of farmed Atlantic salmon (Salmo salar L.): variation between families, gender differences and the importance of maturation
(Master thesis, 2012-04-27)The aim was to study biometric parameters, yield and fillet quality traits of farmed Atlantic salmon (Salmo salar L.) belonging to the 2008 year class of the breeding nucleus of SalmoBreed AS, Norway. The offspring analyzed ... -
Fillet quality of Atlantic salmon (Salmo salar L.). Relevance of dietary amino acid supplementation and acclimation temperature before slaughter
(Master thesis, 2011-10-12)The aim of the present study was to investigate the impact of dietary composition and acclimation temperature before slaughter on fillet quality development of farmed Atlantic salmon (Salmo salar L.). The fish were fed a ... -
Grading of correlated quality traits for added market value in Atlantic salmon (Salmo salar L.) - A model with example data
(Master thesis, 2010-11-29)The quality of the Atlantic salmon (Salmo salar L.) at the time of harvest affects the economic value and is in addition to body weight generally determined by the body composition and carcass quality traits, such as fillet ... -
In vitro effects of antinutrients on gut microbiota from farmed Atlantic salmon
(Master thesis, 2017)Currently investigations on gut microbiota of animals and humans have received increased emphasis as it is thought to be a key factor in metabolism of nutrients, immune system, growth and protection against potential ... -
Influence of dietary tetradecylthioacetic acid (TTA) on lipid content and fatty acid composition in liver of 1+ Atlantic salmon (Salmo salar L.) and sex-specific differences in muscle fat provoked by TTA.
