Data for: Size spectrum model reveals importance of considering species interactions in a freshwater fisheries management context

Inland fisheries have significant cultural and economic value around the globe, providing dietary protein, income, and recreation. Consequently, methods for monitoring and managing these important fisheries are continually being refined. In marine systems, multi-species size spectrum models have been increasingly used to explore management scenarios of important fish stocks within an ecosystem-based fisheries management framework; however, these models have not been applied in freshwater systems. In this study, we developed a multi-species size spectrum model for the fish community of Lake Nipissing, a large, productive lake in Ontario, Canada. To the best of our knowledge, this is the first fully calibrated multi-species size spectrum model for an inland fishery. Using this model, we explored the impacts of different management scenarios on fish community dynamics while taking species interactions into account. Specifically, we examined how changes in fishing mortality affect: (1) spec...

内陆渔业在全球范围内具备显著的文化与经济价值，可为人类提供膳食蛋白质、收入来源与休闲娱乐途径。因此，针对这类重要渔业的监测与管理方法也在持续优化升级。在海洋生态系统中，多物种体型谱模型（multi-species size spectrum model）已愈发广泛地应用于基于生态系统的渔业管理框架内，以探索重要鱼类种群的各类管理情景；但此类模型尚未被应用于淡水生态系统中。本研究针对加拿大安大略省的大型高产湖泊尼皮辛湖（Lake Nipissing）的鱼类群落，构建了一款多物种体型谱模型。据我们所知，这是首款针对内陆渔业完成全校准的多物种体型谱模型。本研究借助该模型，在考量物种间相互作用的前提下，探究了不同管理情景对鱼类群落动态的影响。具体而言，我们考察了捕捞死亡率的变化将如何影响：(1) spec...
