Fisheries are the most common ecosystem service that fish provide to human populations, yet recreational fisheries are often overlooked when evaluating such services. Here, the socioeconomic profiles of fishers, the composition of their catches and catch per unit effort (CPUE) are described, to estimate the economic value of the recreational fishery on a stretch of the Cuiabá River in the Brazilian Pantanal. Questionnaires were used to obtain socioeconomic information and fishing yield from fishers for 2013 and 2014. Additionally, a census on the number of fishers and fishing platforms along the sampled region was conducted in 2018. This recreational fishery mostly involves middle class adult males, based mostly in the Cuiabá city metropolitan region. They invested, on average, US$41.1 (SD = US$16.5, median = $35.2) per fishing visit, catching around 19 fish species. Overall, mean CPUE from the recreational fishery was 42.20 fish/fisher.day (17.4 kg/fisher/day). Annual economic value of this recreational fishery was estimated at around US$1.8 million, which highlights the importance of this activity to the local economy. Greater environmental conservation efforts are recommend to ensure the long-term viability of this ecosystem service.

巴西潘塔纳尔湿地库亚巴河下游休闲渔业的时间动态和经济估值

渔业是鱼类为人类提供的最常见的生态系统服务，但在评估此类服务时，休闲渔业往往被忽视。在这里，描述了渔民的社会经济概况、渔获量的构成和单位努力的渔获量 (CPUE)，以估计巴西潘塔纳尔湿地库亚巴河段休闲渔业的经济价值。问卷用于获取 2013 年和 2014 年渔民的社会经济信息和捕捞产量。此外，2018 年还对采样区域沿线的渔民和捕鱼平台数量进行了普查。这种休闲渔业主要涉及中产阶级成年男性，主要基于在库亚巴市大都市区。他们每次钓鱼平均投资 41.1 美元（标准差 = 16.5 美元，中位数 = 35.2 美元），捕获约 19 种鱼类。总体而言，休闲渔业的平均 CPUE 为 42.20 条鱼/渔民.天（17.4 公斤/渔民/天）。这种休闲渔业的年经济价值估计约为 180 万美元，这突显了该活动对当地经济的重要性。建议加大环境保护力度，以确保这种生态系统服务的长期生存能力。
