A comprehensive, up-datable diagnostic guide for the pathogens and diseases listed in the NACA/FAO/OIE Quarterly Aquatic Animal Disease Reporting System including a number of other diseases which are significant in the Asia region. The information is presented in a format that spans from gross observations at the pond or farm site (Level 1), to guidance for information on technologically advanced molecular or ultrastructural diagnostics and laboratory analyses (Levels II and III, and OIE aquatic animal health standards), thus, taking
into account international, regional, and national variations in disease concerns, as well as varying levels of diagnostic capability between countries of the Asia-Pacific region.
