ABSTRACT
Fish aquaculture is economically important worldwide. However, viral, bacterial, fungal, and parasitic diseases limit successful propagation in aquaculture. Viral diseases found in salmonid fish are infectious hematopoietic necrosis (IHN), Oncorhynchus masou virus (salmonid herpesvirus 2) disease (OMVD), erythrocytic inclusion body syndrome (EIBS), chum salmon virus disease, and viral erythrocytic necrosis (see Chapter 6). Diseases found affecting cultured marine fish include lymphocystis disease (LCD), viral ascites, rhabdovirus disease, viral epithelial hyperplasia, reovirus infection, viral nervous necrosis (VNN), and viral hemorrhagic septicemia (VHS).
