Surmounting evidence supports that infectious agents play a critical role in shaping fish physiology, behaviour, and survival. The exclusion of disease-causing agents from fisheries research has resulted in major knowledge gaps that may limit the predictive capacity of ecological models. A major barrier in wild fisheries epidemiology is the logistical constraints associated with observing disease and obtaining samples from free-ranging fish, restricting the vast majority of research to laboratory studies or aquaculture facilities. For fisheries ecologists, including infectious agents can provide greater insight into observed phenomena, particularly with respect to fish physiology (e.g., metabolism), movement (e.g., migration rates), behaviour (e.g., habitat selection), personality (e.g., bold versus shy), and survival. Here we provide a brief introduction to the current understanding of disease ecology in wild fish and describe technological advances in both epidemiology and fisheries and aquatic sciences that can be used in tandem to create comprehensive studies of disease ecology in wild fishes. Combining nonlethal sampling and molecular genetic-based identification methods with field studies creates vast opportunities for innovative study designs that have the potential to address the true complexity of aquatic ecosystems.

野生鱼类的疾病生态学：将感染指标与行为、状况和生存联系起来的机遇和挑战

大量证据支持感染因子在塑造鱼类生理、行为和生存方面发挥着关键作用。从渔业研究中排除致病因子导致了重大的知识差距，这可能会限制生态模型的预测能力。野生渔业流行病学的一个主要障碍是与观察疾病和从自由放养的鱼身上获取样本相关的后勤限制，将绝大多数研究限制在实验室研究或水产养殖设施中。对于渔业生态学家来说，包括传染性病原体可以提供对观察到的现象的更深入的了解，特别是在鱼类生理学（例如新陈代谢）、运动（例如迁移率）、行为（例如栖息地选择）、个性（例如，大胆与害羞） ) 和生存。在这里，我们简要介绍了当前对野生鱼类疾病生态学的理解，并描述了流行病学、渔业和水生科学方面的技术进步，这些进步可用于对野生鱼类的疾病生态学进行综合研究。将非致命采样和基于分子遗传的鉴定方法与实地研究相结合，为创新研究设计创造了巨大的机会，这些设计有可能解决水生生态系统的真正复杂性。
