Many ecosystems continue to experience rapid transformations due to processes like land use change and resource extraction. A systems approach to maintaining natural resources focuses on how interactions and feedbacks among components of complex social-ecological systems generate social and ecological outcomes. In recreational fisheries, residential shoreline development and fish stocking are two widespread human behaviors that influence fisheries, yet emergent social-ecological outcomes from these potentially interacting behaviors remain under explored. We applied a social-ecological systems framework using a simulation model and empirical data to determine whether lakeshore development is likely to promote stocking through its adverse effects on coarse woody habitat and thereby also on survival of juvenile and adult fish. We demonstrate that high lakeshore development is likely to generate dependency of the ecosystem on the social system, in the form of stocking. Further, lakeshore development can interact with social-ecological processes to create deficits for state-level governments, which threatens the ability to fund further ecosystem subsidies. Our results highlight the value of a social-ecological framework for maintaining ecosystem services like recreational fisheries.
由于土地利用变化和资源开采等过程，许多生态系统仍在经历快速转型。维持自然资源的系统方法侧重于复杂社会生态系统各组成部分之间的相互作用和反馈如何产生社会和生态结果。在休闲渔业中，住宅岸线开发和鱼类放养是两种广泛存在的人类行为，它们会影响渔业，但这些潜在相互作用行为产生的新兴社会生态结果仍未得到充分探索。我们应用社会生态系统框架，使用模拟模型和实证数据，来确定湖滨开发是否可能通过对粗木质生境产生不利影响，从而对幼鱼和成年鱼的生存产生影响，进而促进鱼类放养。我们的研究结果表明，高湖滨开发可能会使生态系统在放养的形式上依赖于社会系统。此外，湖滨开发可以与社会生态过程相互作用，为州级政府造成赤字，从而威胁到为进一步的生态系统补贴提供资金的能力。我们的研究结果强调了社会生态框架在维持休闲渔业等生态系统服务方面的价值。
