Shrimp is not only one of the world's most valuable aquaculture species, but also a species that encounter high economic losses due to diseases. Diseases are sufficiently important to influence global supply and prices for longer periods. Profitability is the driving force behind shrimp farming and high profits associated with the absence of disease largely determines where shrimp production does take place; i.e. prevalence of disease leads to geographic relocation. In this paper, a basic economic model for the impact of the disease on a shrimp farm is provided and a Monte Carlo simulation is provided to illustrate the impact of disease on economic risk. Improved technologies, knowledge, and governance are important elements utilized in the mitigation of diseases in various shrimp producing countries. Economic aspects such as profitability in the absence and presence of diseases and cost of treatment determines the global production of shrimp along with shaping technologies and production systems.
虾不仅是世界上最有价值的水产养殖物种之一，也是因疾病而遭受高经济损失的物种。疾病的重要性足以在较长时间内影响全球供应和价格。盈利能力是虾养殖的驱动力，与疾病无关的高利润在很大程度上决定了虾生产的地点；也就是说，疾病的流行导致了地理位置的转移。本文提供了一个基本的经济模型，用于研究疾病对虾养殖场的影响，并提供了蒙特卡罗模拟，以说明疾病对经济风险的影响。在各个虾生产国家，改进的技术、知识和治理是减少疾病的重要因素。在没有和有疾病的情况下的盈利能力以及治疗成本等经济方面决定了全球虾的产量，同时也塑造了技术和生产系统。
