传染病在经济上对水产养殖有害，随着水产养殖的持续扩大和集约化，管理传染病的重要性在未来可能会增加。在这里，我们使用进化的毒力理论，沿着的例子，以确定水产养殖的做法，可能会导致增加病原体毒力的演变。我们确定了水产养殖中常见的八种实践，理论预测可能有利于向更高的病原体毒力进化。四项与密集水产养殖业务有关，另外四项与传染病控制具体有关。我们的目的是让水产养殖管理者意识到这些风险，这样，随着警惕性的提高，他们可能能够检测和预防未来越来越麻烦的病原体菌株的出现和传播。
Infectious diseases are economically detrimental to aquaculture, and with continued expansion and intensification of aquaculture, the importance of managing infectious diseases will likely increase in the future. Here, we use evolution of virulence theory, along with examples, to identify aquaculture practices that might lead to the evolution of increased pathogen virulence. We identify eight practices common in aquaculture that theory predicts may favor evolution toward higher pathogen virulence. Four are related to intensive aquaculture operations, and four others are related specifically to infectious disease control. Our intention is to make aquaculture managers aware of these risks, such that with increased vigilance, they might be able to detect and prevent the emergence and spread of increasingly troublesome pathogen strains in the future.
