    Abstract

    Acute hepatopancreatic necrosis disease (AHPND) has caused severe losses in farmed populations of marine shrimp Penaeus vannamei and P. monodon. The causative agents are unique strains of the bacteria Vibrio parahaemolyticus and related Vibrio species. The disease emerged in the People's Republic of China (China) and Vietnam in 2010 and spread throughout South-East Asia; it was later reported in countries in both North and South America. The disease has had significant economic impacts on the shrimp aquaculture industry. From 2010 to 2016, combined losses from China, Malaysia, Mexico, Thailand and Vietnam due primarily to outbreaks of AHPND, including losses at the farm gate and those resulting from a drop in feed sales and exports, were estimated at over US$ 44 billion. Other economic losses include those associated with processing facilities, decreased community revenues resulting from increased unemployment, financial investments, and the costs of implementing diagnostic and control measures. The reduced employment opportunities and increases in debt burden and investment risk have had sociological impacts. The responses to the disease have led to a gradual recovery of the shrimp industry in affected countries. These response efforts have included the implementation of changes in farming systems and management, including, among others, enhanced biosecurity and the use of AHPND-free and AHPND-resistant shrimp. This situation of losses and recovery illustrates the importance of having a multi-level response plan in place to prevent, or to reduce the risk of, outbreaks of disease.
