The COVID-19 pandemic has led to environmental recovery in some ecosystems from a global "anthropause," yet such evidence for natural resources with extraction or production value (e.g., fisheries) is limited. This brief report provides a data-driven global snapshot of expert-perceived impacts of COVID-19 on inland fisheries. We distributed an online survey assessing perceptions of inland fishery pressures in June and July 2020 to basin-level inland fishery experts (i.e., identified by the Food and Agriculture Organization of the United Nations across the global North and South); 437 respondents from 79 countries addressed 93 unique hydrological basins, accounting for 82.1% of global inland fish catch. Based on the responses analyzed against extrinsic fish catch and human development index data, pandemic impacts on inland fisheries 1) add gradation to the largely positive environmental narrative of the global pandemic and 2) identify that basins of higher provisioning value are perceived to experience greater fishery pressures but may have limited compensatory capacity to mitigate COVID-19 impacts along with negative pressures already present.
新冠疫情导致了一些生态系统从全球“人类停摆”中得到环境恢复,但对于具有提取或生产价值的自然资源(例如渔业),这种证据是有限的。本简要报告提供了一个数据驱动的全球视角,展示了新冠疫情对内陆渔业的专家感知影响。我们在 2020 年 6 月和 7 月向流域层面的内陆渔业专家(即由联合国粮食及农业组织在全球北方和南方确定的专家)分发了一份在线调查,评估他们对内陆渔业压力的看法;来自 79 个国家的 437 名受访者针对 93 个独特的水文流域做出了回应,这些流域占全球内陆鱼类捕捞量的 82.1%。根据针对外来鱼类捕捞量和人类发展指数数据进行的分析,内陆渔业的疫情影响 1)对全球大流行的环境积极叙事增添了层次,2)表明提供更高价值的流域被认为面临更大的渔业压力,但可能没有足够的补偿能力来减轻新冠疫情的影响,以及已经存在的负面压力。
