An updated survey of freshwater fishes within Letchworth State Park and surrounding areas of the Genesee River
收藏资源简介：
The goal of this study was to gather information about freshwater fishes in Letchworth State Park (42.615275°N, -77.992825°W), a portion of New York State-owned land located in the Genesee River watershed that lacks known data about its fish diversity. The fish collection took place between 2017 and 2019 in the Genesse River upstream and downstream of the falls using gill, hoop, and seine netting and electrofishing. This was the first attempt at a comprehensive survey of this portion of the river, which allowed for a baseline to be established regarding fish biodiversity in the region. The updated total number of species found in this portion of the Genesee River was 25, 22 of which were newly identified downstream of the falls, in Letchworth State Park. We encourage further collection and continuation of this survey with consistent sampling techniques to promote ongoing field surveys and fish collection that inform freshwater fish diversity in stream ecosystems across the globe.
本研究旨在收集莱奇沃思州立公园（Letchworth State Park，北纬42.615275°N，西经77.992825°W）内淡水鱼类的相关信息。该区域为纽约州所辖土地，坐落于杰纳西河（Genesee River）流域，此前尚无关于其鱼类多样性的公开数据。鱼类采集工作于2017年至2019年间，在瀑布上下游的杰纳西河河段开展，采用刺网（gill net）、筒网（hoop net）、围网（seine net）及电渔法（electrofishing）进行采样。本次调查是对该河段的首次全面鱼类普查，可为建立该区域鱼类生物多样性基线提供科学依据。经更新，杰纳西河该河段记录的鱼类物种总数达25种，其中22种为莱奇沃思州立公园内瀑布下游水域的新发现物种。我们鼓励采用统一采样技术开展后续采集与持续调查，以推动全球溪流生态系统淡水鱼类多样性相关的野外调查与鱼类采集工作，为相关研究积累数据。
