Inland recreational fishing is primarily considered a leisure-driven activity in freshwaters, yet its harvest can contribute to food systems. Here we estimate that the harvest from inland recreational fishing equates to just over one-tenth of all reported inland fisheries catch globally. The estimated total consumptive use value of inland recreational fish destined for human consumption may reach US$9.95 billion annually. We identify Austria, Canada, Germany and Slovakia as countries above the third quantile for nutrition, economic value and climate vulnerability. These results have important implications for populations dependent on inland recreational fishing for food. Our findings can inform climate adaptation planning for inland recreational fisheries, particularly those not currently managed as food fisheries.
内陆休闲渔业主要被视为淡水环境中的休闲活动，但它的捕捞量可以为食物系统做出贡献。在这里，我们估计内陆休闲渔业的捕捞量仅略高于全球所有内陆渔业捕捞量的十分之一。预计用于人类消费的内陆休闲鱼类的总消费使用价值每年可能达到 99.5 亿美元。我们确定奥地利、加拿大、德国和斯洛伐克为营养、经济价值和气候脆弱性均高于第三分位数的国家。这些结果对依赖内陆休闲渔业获取食物的人群具有重要意义。我们的研究结果可以为内陆休闲渔业的气候适应规划提供信息，特别是那些目前不作为鱼类养殖渔业进行管理的渔业。
