BIOS BIOSECURITY IN N WOR ORLD PR PRAWN FAR ARMING Diseases are the most significant challenge. Billions of Dollars lost. Most devastating diseases: White Spot Syndrome Virus (WSSV); Early Mortality Syndrome (EMS) and more recently Enterocytozoon hepatopenaei (EHP). Lack of proper understanding of biosecurity risk management. Aquaculture Biosecure Systems by Francois Brenta
