摘要

目标手工渔业占世界渔业捕获量的 40%,但其对环境的影响仍鲜为人知。发展中国家的情况尤其如此。在这项研究中,我们试图将当地渔民的知识与分布模型结合起来,以估算的的喀喀湖濒危特有鸟类罗兰迪亚䴙䴘(Rollandia microptera)的年误捕量,这种鸟类的主要人为威胁是误捕。我们利用水深测量、与海岸的距离、与居民点的距离、与保护区的距离、有无水产养殖、与水产养殖的距离以及湿地覆盖率,使用最大熵模型构建了渔业分布模型。我们对捕鱼者进行了访谈,询问他们误捕鸊鷉的频率,并在不同地点进行了短期监测,同时对死亡鸊鷉进行了横断面测量。分布模型的曲线下面积(AUC)为 0.89,真实技能统计量为 0.67,这表明最大熵模型可以模拟渔业的发生。我们的访谈结果表明,每年作为副渔获物被捕获的鸊鷉数量之大在生物学上是难以置信的。访谈的文化背景(包括无响应和社会可取性偏差的潜在影响)以及访谈对象通常将的的喀喀鸊鷉视为讨厌物种的渔民,可能会导致对副渔获物的过度报告,从而导致这些难以置信的数字。然而,由于文化因素影响了渔民回答的准确性,通过访谈获得准确的渔业混获量比较困难。虽然我们希望这种方法能为监测提供一种低成本的替代方法,但它并不能取代监测。

Problems with combining modelling and social science approaches to understand artisanal fisheries bycatch
AimArtisanal fisheries account for 40% of the world's fisheries catch, yet its environmental impacts remain poorly understood. This is especially the case in developing countries. In this study, we sought to integrate Local Fisher's Knowledge with distribution modelling to estimate the annual bycatch of Titicaca Grebe (Rollandia microptera), an endangered endemic bird from Lake Titicaca whose main anthropogenic threat is bycatch.LocationLake Titicaca, Peru and Bolivia.MethodsWe conducted transect and point counts of fishing nets in March–September 2022 and conducted interviews with fishers across the Lake Titicaca region. Using bathymetry, distance from shore, distance from a settlement, distance from the protected area, presence/absence of aquaculture, distance from aquaculture, and wetland cover, we constructed a distribution model of fisheries using maximum entropy modelling. We conducted interviews with fishers asking about the frequency of grebe bycatch and conducted short‐term monitoring at various sites while conducting transect points for dead grebes.ResultsWe estimate 3270 km2 of the surface area of Lake Titicaca is used for fishing, which amounts to 39.40% of the lake's surface area. The area under the curve (AUC) of the distribution model was 0.89 and the True Skill Statistic was 0.67, which suggests maximum entropy modelling can model fisheries occurrence. The results of our interviews suggested a biologically implausible large number of grebes caught as bycatch annually. The cultural context of the interviews, including potential influences of non‐response and social‐desirability bias, being with fishers who often view the Titicaca Grebe as a nuisance species, might have caused over‐reporting of bycatch and hence led to these implausible figures.Main ConclusionsIt is possible to map fisheries using distribution models as one might with species. However, obtaining accurate measures of fisheries bycatch through interviews is more difficult, due to cultural factors which affect the accuracy in fisher's responses. While we hope that this method provides a low‐cost alternative to monitoring, it is not a suitable replacement for it.

期刊介绍: Diversity and Distributions is a journal of conservation biogeography. We publish papers that deal with the application of biogeographical principles, theories, and analyses (being those concerned with the distributional dynamics of taxa and assemblages) to problems concerning the conservation of biodiversity. We no longer consider papers the sole aim of which is to describe or analyze patterns of biodiversity or to elucidate processes that generate biodiversity.
