abstract
A shrimp farm is an aquaculture business contributes more than 50 per cent of the total shrimp exports from India for human consumption. Shrimp aquaculture is affected by the outbreak of various microbial diseases which causes severe mortality in shrimp farming industry. Viral and bacterial diseases are of major concern in shrimp farming systems. Improper use of antibiotics and chemical drugs in aquaculture is accompanied with the potential negative impacts on the environment as well as human health and is also ineffective for many pathogens, particularly virus. Although the effective control of infectious viral diseases without chemicals is important in the cultivation of aquatic organisms. Therefore, advance research is required to standardize prophylactic and control measures in shrimp aquaculture in order to reduce the risk of adverse effects of new disease introduction. Thus, all the information in this review relates to prophylactics that protect the cultivation shrimp industries.
