Triploid Atlantic salmon are a valuable part of production in Tasmania. In fact, not undergoing sexual maturation, triploids are used to ensure appropriately sized harvest fish all year round. Nevertheless, triploids tend to develop a higher prevalence of skeletal anomalies than diploids affecting mainly the lower jaw and the vertebral column and impacting fish performance, welfare and value deleteriously. The general intent of this PhD research project was to make a useful contribution to Atlantic salmon industry in order to understand and find a possible solution or mitigate the problem of skeletal anomalies of obvious relevance to economic efficiency as well as animal welfare in Tasmania and worldwide. This research explored the occurrence of several skeletal anomalies in farmed diploid and triploid Atlantic salmon in freshwater that represent a critical phase in development. The aims were to improve our knowledge on occurrence and causative factors of skeletal anomalies in triploids (and diploids) and in ...
