Inland fisheries face multiple, intensifying threats (i.e., proximate human pressures causing degraded ecological attributes) from land development, climate change, resource extraction, and competing demands for water resources. Planning for resiliency amidst these pressures requires understanding the factors that influence an inland fishery’s capacity to adapt to system changes under multiple threats. Incorporating expert knowledge can illuminate priority fisheries and provide important insights where data are otherwise limited. Using data from a global survey of 536 fishery professionals, this study examines perceptions of threats and adaptive capacity (i.e., ability to mitigate or respond to change) in major inland fisheries. We assessed associations across 29 different perceived threats and their ranked influence scores, tested agreement among five adaptive capacity domains (i.e., agency, assets, flexibility, learning, organization), and examined relationships between threats and adaptive capacity domains. Results provide quantitative evidence that the greatest threats to inland fisheries come from outside the fishing sector and that most inland fisheries face multiple threats. Results also support the five domains as a collective measure of adaptive capacity and illuminate a negative association between the threats to a fishery and a fishery’s adaptive capacity. These findings highlight the need for fishery managers to engage in decision making with non-fishery sectors (e.g., multi-sectoral management) and the prioritization of habitat and watershed-scale conservation and rehabilitation efforts for improved adaptability amidst ecological transformation.

面临人为压力的内陆渔业的适应能力


内陆渔业面临来自土地开发、气候变化、资源开采和对水资源的竞争性需求的多重、日益加剧的威胁（即，导致生态属性退化的直接人类压力）。在这些压力中规划弹性需要了解影响内陆渔业在多重威胁下适应系统变化能力的因素。整合专家知识可以阐明优先渔业，并在数据有限的情况下提供重要的见解。本研究使用对 536 名渔业专业人士的全球调查数据，研究了主要内陆渔业对威胁的看法和适应能力（即减轻或应对变化的能力）。我们评估了 29 种不同感知威胁的关联及其排名影响分数，测试了五个适应性能力领域（即代理、资产、灵活性、学习、组织）之间的一致性，并研究了威胁与适应性能力领域之间的关系。结果提供了定量证据，表明内陆渔业面临的最大威胁来自渔业部门之外，并且大多数内陆渔业面临多重威胁。结果还支持将这五个领域作为适应能力的集体衡量标准，并阐明了渔业面临的威胁与渔业适应能力之间的负相关。这些发现突出了渔业管理者与非渔业部门一起参与决策（例如，多部门管理）的必要性，以及优先考虑栖息地和流域规模的保护和恢复工作，以提高生态转型中的适应性。
