Bio security is a board concept and the application of bio security concepts to shrimp aquaculture will contribute significantly to reduce losses due to diseases and make this sector more sustainable and environmentally responsible. Implementation of bio security practices is an increasingly pressing issue for fisheries and aquaculture managers, considering the importance of this sector in terms of food security and economic development of the people. Bio security measures implemented appropriately can be a cost-effective way of managing disease risks. Adopting quarantine measures for brood stock prior to their use, adopting best management practices (SOP’s) by implementing good sanitary practices, treating water before use, optimizing stock density of larvae and maintaining good water quality will help in achieving bio security in hatcheries., At the farm level, implementing bio security plan requires modifying existing farms and management routines. Main preventive measures at pond/ farm level include proper pond preparation to eliminate pathogens and their carriers, treatment of water in reservoirs to inactivate free viruses and kill virus out, closed zero-water exchange systems to avoid contamination form source water. Shrimp Ponds with a history of disease outbreaks have a greater likelihood of future disease outbreaks, and hence, special attention is required during pond preparation.
