Recreational fisheries have high economic worth, valued at US$190 billion globally. An important, but underappreciated, secondary value of recreational catch is its role as a source of food. This contribution is poorly understood due to difficulty in estimating recreational harvest at spatial scales beyond a single system, as traditionally estimated from individual creel surveys. Here, we address this gap using 28‐year creel surveys of ~300 Wisconsin inland lakes. We develop a statistical model of recreational harvest for individual lakes and then scale‐up to unsurveyed lakes (3,769 lakes; 73% of statewide lake surface area). We generate a statewide estimate of recreational lake harvest of ~4,200 metric tons and an estimated annual angler consumption rate of ~1.1 kg, nearly equal to the total estimated United States per capita freshwater fish consumption. An important ecosystem service, recreational harvest makes significant contributions to human diets and plays an often‐unheralded role in food security.

捕捞食物：量化威斯康星州湖泊的休闲渔业收获

休闲渔业具有很高的经济价值，全球渔业价值达1900亿美元。休闲捕获的一个重要但未被重视的次要价值是其作为食物来源的作用。传统上根据单个纱架调查估计，由于难以估算超出单个系统的空间尺度上的休闲娱乐收获，因此对此贡献的了解很少。在这里，我们通过对约300个威斯康星州内陆湖泊进行了28年的纱架调查来解决这一差距。我们建立了单个湖泊休闲收获的统计模型，然后扩大到未调查的湖泊（3,769个湖泊；全州湖泊表面积的73％）。我们对全州范围内休闲湖的收成进行了约4,200吨的估算，而垂钓者的年消费量约为1.1公斤，几乎等于美国人均淡水鱼消费量的估计总数。娱乐性收获是重要的生态系统服务，对人类的饮食做出了重大贡献，并在粮食安全中起着前所未有的作用。
