Risk of contamination of sturgeon species along the Lower Danube with AcIV-E virus from sturgeons raised in aquaculture systems

Abstract It is considered that most infections caused by pathogen agents in fish species raised the closed medium like fishing farms originate from natural environment, thus there are few information on virus transmission aquaculture programs to wild ones. This issue important taking into account sturgeon populations critically endangerment, and regarding IUCN Red List, two of these already declared extinct. Within Danube Basin, environmental anthropic factors series (reproduction habitats lost, hydrotechnical works) have distribution area be restricted mainly lower segment river. In addition, intensive or introduction invasive produced negative effects hence decrease population effectiveness. As result, six native within our days, only four still found. review shall include an analysis status knowledge, possible influence which some viruses sNCLDV ones, also it propose assessment risk infection ichthyofaunal.
