A quantitative genetic study on the proportion of males in tilapia
Lozano, Carlos (PhD Thesis;2011:63, Doctoral thesis, 2011)Early sexual maturation is one the main constraints in Tilapia farming since early breeding causes stunted growth and large size variability. To circumvent this problem all-male populations are used commercially, and ... -
Derivation of economic values for important production traits in Atlantic salmon
Wu, Liyasu (Master thesis, 2020)Atlantic salmon breeding programs selected several traits simultaneously. Lack of economic values may lead to inappropriate relative weighting of the traits selected for and with a suboptimal long-term genetic gain of the ... -
Genetic variation in egg traits and early survival in rainbow trout
Lamichhane, Anusha (Master thesis, 2021)In farmed rainbow trout a large part of fertilized and incubated eggs and alevins are lost from fertilization until first feeding. The present study was conducted to estimate the overall means of different egg traits and ... -
Genetic variation in susceptibility of Atlantic salmon (Salmo salar L.) to salmon lice, Lepeophtherius salmonis, from field and challenge tests
Muhammed, Muhammed Suleamn (Master thesis, 2018)Sea lice, Lepeophtheirus salmonis (L. salmonis) is the major threats for Norwegian salmon farming industry and the cost of the parasite was estimated to be around five billion NOK per year. Chemical treatments have been ... -
Genome-wide association study of resistance to cardiomyopathy syndrome (CMS) in Atlantic salmon (Salmon salar L.)
Ding, Jingwen (Master thesis, 2019)Cardiomyopathy syndrome (CMS) is considered as a serious viral disease in Norwegian farmed Atlantic salmon. Outbreaks of the disease occur without any observable signs and CMS primarily affects adult salmon. In 2011, piscine ... -
Genome-wide association study of the genetic basis for resistance to IPNV in rainbow trout
Ahmad, Aqeel (Master thesis, 2022)Infectious Pancreatic Necrosis (IPN), caused by the IPN virus, is one of the major threats to the Norwegian rainbow trout (NRT) industry. Despite disinfection, effective management, traditional breeding programs, and efforts ... -
Mørke flekker i laksefilet. Kunnskapsstatus og tiltak for å begrense omfanget
Mørkøre, Turid; Larsson, Thomas; Kvellestad, Agnar Ståle; Koppang, Erling Olaf; Åsli, Magnus; Krasnov, Aleksei; Dessen, Jens-Erik; Moreno, Helena Maria; Valen, Elin Christine; Gannestad, Kjellrun Hoås; Gjerde, Bjarne; Taksdal, Torunn; Bæverfjord, Grete; Meng, Yuqiong; Heia, Karsten; Wold, Jens Petter; Borderias, A.J.; Moghadam, Hooman; Romarheim, Odd Helge; Rørvik, Kjell-Arne (Research report, 2015)Forekomsten av mørke flekker i laksefilet har økt betraktelig senere årene. I dag har hver femte filet slike flekker som i hovedsak er opp til 3 cm i diameter og lokalisert til filetens bukområde. Store ryggflekker har ... -
QTLs Associated with Resistance to Cardiomyopathy Syndrome in Atlantic Salmon
Boison, Solomon Antwi; Ding, Jingwen; Leder, Erica; Gjerde, Bjarne; Bergtun, Per Helge; Norris, Ashie; Baranski, Matthew; Robinson, Nicholas Andrew (Peer reviewed; Journal article, 2019) -
Quantitative genetics of cardiac traits in Atlantic salmon (Salmo salar L.)
Vassgård, Siri (Master thesis, 2017)Mortality of apparently healthy looking fish is frequently reported close to harvesting size of Atlantic salmon (Salmo salar L.), causing concerns from an economic and ethical perspective for the Aquaculture industry. ... -
Quantitative Genetics of Growth Rate and Filet Quality Traits in Atlantic Salmon Inferred From a Longitudinal Bayesian Model for the Left-Censored Gaussian Trait Growth Rate
Kristjánsson, Ólafur Hjörtur; Gjerde, Bjarne; Ødegård, Jørgen; Lillehammer, Marie (Peer reviewed; Journal article, 2020) -
Quantitative genetics of traits related to disease resistance and effects of vaccination in Atlantic salmon (Salmo salar)
Drangsholt, Tale Marie Karlsson (PhD Thesis;2011:39, Doctoral thesis, 2011)Disease resistance is of major importance to the fish farming industry as disease outbreaks have negative effects on the industry’s economy, its reputation and on fish welfare. Today, almost all fish in the Norwegian salmon ... -
Validation and genetic parameters of the X-ray method for phenotyping individual feed intake in Atlantic salmon
Difford, Gareth Frank; Hatlen, Bjarne; Gjerde, Bjarne; Heia, Karsten; Bæverfjord, Grete; Norris, A.; Sonesson, Anna Kristina (Peer reviewed; Journal article, 2024)Feed efficiency is a highly desirable breeding goal trait as it can potentially reduce the relative economic cost of feed and concurrently reduce the environmental footprint of fish production. However, recording feed ...
