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.
传染病对水产养殖在经济上造成损害，并且随着水产养殖的持续扩张和集约化，未来管理传染病的重要性可能会增加。在此，我们运用毒力进化理论并结合实例，来确定可能导致病原体毒力增强进化的水产养殖实践。我们识别出水产养殖中常见的八种实践，理论预测这些实践可能有利于向更高病原体毒力的进化。其中四种与集约化水产养殖操作相关，另外四种则专门与传染病控制相关。我们的目的是让水产养殖管理者意识到这些风险，以便他们提高警惕，未来或许能够检测并预防日益棘手的病原体菌株的出现和传播。
