 This thesis uses the current genetic and genomic resources to permit genetic improvement of stress response in European sea bass and disease resistance in gilthead sea bream, two traits of economical importance. One way to integrate such genetic knowledge into breeding programmes, is to detect for quantitative trait loci (QTLs), which are regions of the genome influencing a specific trait. The first step was to design successful experiments to detect QTLs in aquaculture species. The next part of the thesis focuses on QTL mapping in natural mating mass-spawning species, which have complex population structure (variable family sizes). Finally, the possibilities of using genomic selection for mass-spawning species, where natural mating is used, were investigated.
