| European seabass is one of the most economic species in aquaculture in Mediterranean areas. Viral nervous necrosis (VNN), a disease affecting at least 70 aquatic species, has become the most serious threat to seabass cultured industry. While numerous studies have been performed in order to control this disease, no simple and effective procedures are available. In this thesis, we question genetic variability and the potential of selective breeding as an opportunity to address thwart this threat.After a general introduction (first chapter) and a deep literature review of nodavirus in aquaculture (second chapter), we explore in the third chapter the genetic variability of resistance of different wild populations of European seabass, namely Northern Atlantic... |
