人类驱动的环境变化是最近世界上许多大湖水透明度变化的基础，但我们对这些变化对它们所支持的鱼类和渔业的影响的理解仍然不完整。在这里，我们提供了一个框架来组织当前的知识，指导未来的研究，并帮助渔业管理者了解水的清晰度如何影响他们宝贵的种群。在可能的情况下，我们强调劳伦斯五大湖的发现，描述了水的透明度变化如何通过改变紫外线暴露、觅食成功、捕食风险、繁殖行为或领地，直接影响鱼类种群和群落。我们还讨论了水的透明度变化如何通过影响渔民的行为和采样效率(即可捕获性)来影响渔业的收获和评估。最后，我们讨论了改变水的透明度是否会影响渔业绩效的未被研究的方面，包括经济和社区利益。最后，我们确定了一般性预测，并讨论了它们对劳伦斯五大湖优先研究问题的影响。尽管这项工作的动机是区域性的，但审查的广度和框架的一般性很容易转移到其他淡水和海洋生境。
Human-driven environmental change underlies recent changes in water clarity in many of the world’s great lakes, yet our understanding of the consequences of these changes on the fish and fisheries they support remains incomplete. Herein, we offer a framework to organize current knowledge, guide future research, and help fisheries managers understand how water clarity can affect their valued populations. Emphasizing Laurentian Great Lakes findings where possible, we describe how changing water clarity can directly affect fish populations and communities by altering exposure to ultraviolet radiation, foraging success, predation risk, reproductive behavior, or territoriality. We also discuss how changing water clarity can affect fisheries harvest and assessment through effects on fisher behavior and sampling efficiency (i.e., catchability). Finally, we discuss whether changing water clarity can affect understudied aspects of fishery performance, including economic and community benefits. We conclude by identifying generalized predictions and discuss their implications for priority research questions for the Laurentian Great Lakes. Even though the motivation for this work was regional, the breadth of the review and generality of the framework are readily transferable to other freshwater and marine habitats.
