Abstract

Abstract The Yarinacocha lake is an emblematic ecosystem of the Peruvian Amazon, representing the main point of fish landing and a tourist attraction in the city of Pucallpa. The wide fauna diversity in this area has made it the target of various studies, although for fish species most of them were focused on commercial species. In this work, we carried out the first ichthyofauna species inventory of the Yarinacocha lake, sampling throughout the entire lake during the rainy and dry seasons and considering also all previously recorded species deposited in the Ichthyological Collection of the MUSM with the same locality. A total of 164 fish species were recorded, representing 10 orders (plus Eupercaria), 34 families and 116 genera. Characiformes was the order with more species (68 spp., 41.5%) followed by Siluriformes (59 spp., 36%), Cichliformes (17 spp., 10.5%), and Gymnotiformes (8 spp., 4.9%). The most highly represented families, including almost 55.5% of the total diversity obtained, were Characidae (23 spp., 14%), followed by Cichlidae (17 spp., 10.4%), Loricariidae (14 spp., 8.5%), Pimelodidae (13 spp., 7.9%), Doradidae (13 spp., 7.4%) and Anostomidae (12 spp., 7.3%). From the total fish species recorded in this study, only 22 are considered protected species following the IUCN criteria and 109 species have commercial importance, including 90 ornamental species (54.8%). Our results contribute to the knowledge of the ichthyofauna of the Yarinacocha lake and can be used as a starting point for its conservation and sustainable management over time.

亚里纳科查湖的鱼:秘鲁普卡尔帕乌卡亚利河下游流域的标志性亚马逊生态系统

亚里纳科查湖是秘鲁亚马逊河的标志性生态系统，代表了鱼类登陆的主要地点和普卡尔帕市的旅游景点。该地区广泛的动物多样性使其成为各种研究的目标，尽管对鱼类的研究大多集中在商业物种上。在这项工作中，我们对Yarinacocha湖进行了第一次鱼系物种清查，在雨季和旱季对整个湖进行了采样，并考虑了在同一地点沉积在MUSM鱼类学收集中的所有先前记录的物种。共记录到鱼类164种，隶属于10目(加上欧洲鱼)、34科、116属。其次是志留形目(59种，36%)、慈鱼形目(17种，10.5%)和裸子形目(8种，4.9%)。最具代表性的科为麻蝇科(23种，占总多样性的14%)，其次为姬蝇科(17种，10.4%)、蠓科(14种，8.5%)、蠓科(13种，7.9%)、蠓科(13种，7.4%)和蠓科(12种，7.3%)。在本研究记录的所有鱼类中，只有22种被认为是符合IUCN标准的受保护物种，109种具有商业重要性，其中包括90种观赏物种(54.8%)。我们的研究结果有助于了解亚里纳科查湖的鱼类区系，并可作为其保护和可持续管理的起点。
