![]() ![]() ![]() Nous présentons un cadre pour organiser les connaissances actuelles, orienter la recherche future et aider les gestionnaires des pêches à comprendre l’incidence possible de la clarté de l’eau sur les populations qu’ils gèrent. Si des modifications de l’environnement causées par les humains sous-tendent les changements récents de la clarté de l’eau dans bon nombre des grands lacs de la planète, notre compréhension des conséquences de ces changements sur les poissons et les pêches qu’ils soutiennent demeure incomplète. ![]() ![]() 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. We conclude by identifying generalized predictions and discuss their implications for priority research questions for the Laurentian Great Lakes. Finally, we discuss whether changing water clarity can affect understudied aspects of fishery performance, including economic and community benefits. We also discuss how changing water clarity can affect fisheries harvest and assessment through effects on fisher behavior and sampling efficiency (i.e., catchability). 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. 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. 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. ![]()
