Fish populations targeted by recreational and artisanal fisheries remain largely unassessed in low- and middle-income countries. This generally results in a lack of regulatory action from government agencies, thus aggravating the risk of overfishing. In this context, sources of historical information, such as local ecological knowledge (LEK), are key to providing insight on the status of fish populations and informing management. Systematized elicitation processes have increasingly shown an ability to produce quantitative indicators while reducing biases and caveats inherent to expert knowledge. In this study, we assessed changes in composition of the catch, species abundance, and geographical distribution of the catch for 10 data-poor coastal groundfish species of Peru using LEK.

当地生态知识（LEK）表明秘鲁沿海底鱼的过度捕捞和连续枯竭

在低收入和中等收入国家，休闲渔业和手工渔业的目标鱼类种群在很大程度上仍未得到评估。这通常会导致政府机构缺乏监管行动，从而加剧过度捕捞的风险。在这种情况下，历史信息来源，例如当地生态知识（LEK），是了解鱼类种群状况和为管理提供信息的关键。系统化的启发过程越来越显示出产生定量指标的能力，同时减少专家知识固有的偏见和警告。在本研究中，我们使用 LEK 评估了秘鲁 10 种缺乏数据的沿海底鱼物种的渔获量构成、物种丰度和渔获量地理分布的变化。
