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.

改变水透明度对劳伦森五大湖鱼类和渔业的影响

人类驱动的环境变化是世界上许多大湖最近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。在此，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澈度如何影响其重要种群。我们尽可能强调 Laurentian Great Lakes 的发现，我们描述了水透明度的变化如何通过改变暴露于紫外线辐射、觅食成功、捕食风险、繁殖行为或领土范围来直接影响鱼类种群和社区。我们还讨论了水清澈度的变化如何通过影响渔民行为和采样效率（即可捕获性）来影响渔业捕捞和评估。最后，我们讨论了改变水的透明度是否会影响渔业绩效的研究不足的方面，包括经济和社区利益。最后，我们确定了广义预测，并讨论了它们对劳伦森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，但框架的审查范围和一般性很容易转移到其他淡水和海洋栖息地。
