Environmental DNA (eDNA) and Fish Capture Data from Round Goby Screening Surveys on the Eastern Erie Canal, New York (ver. 2.0, May 2024)

he dataset is composed of four tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) at 12 sites on the Eastern Erie Canal in New York between Oneida Lake and the Hudson River from 2016 to 2023. The sampling techniques and frequency of sampling were adapted over time to optimize the efficiency of the study effort. From 2016-2019 eDNA water sampling and traditional fish surveys using seining, trapping, and benthic trawling were conducted twice annually (spring and summer) at the 12 sites. From 2020-2022, eDNA water sampling and traditional fish surveys using benthic trawling and electrofishing were conducted twice annually (spring and summer). In 2023, benthic trawling and electrofishing were conducted once (summer). The first table "eDNAData" contains environmental DNA data, the second table "FishCaptureData" contains fish community data from the traditional fish sampling methods, the third table "GobyLWData" contains length and weight measurements for all captured Round Goby beginning in 2020, and the fourth table "SiteData" contains information on the 12 study sites.

本数据集包含四张表格，数据采集于2016年至2023年间，采集地点为美国纽约州伊利运河东段（奥奈达湖与哈德逊河之间）的12个采样点，用于入侵物种圆背虾虎鱼（Round Goby，*Neogobius melanostomus*）的筛查调查。采样技术与采样频次随研究进程动态调整，以优化研究工作效率。2016-2019年，研究团队在12个采样点每年开展两次采样（春季与夏季），采样方式包括环境DNA (environmental DNA, eDNA)水样采集，以及围网、诱捕、底拖网等传统鱼类调查手段。2020-2022年，采样频次维持为每年两次（春季与夏季），但采样方式调整为环境DNA (eDNA)水样采集、底拖网与电渔法传统鱼类调查。2023年，仅在夏季开展一次底拖网与电渔法采样。第一张表格"eDNAData"收录环境DNA相关数据；第二张表格"FishCaptureData"收录传统鱼类采样方法获取的鱼类群落数据；第三张表格"GobyLWData"收录2020年起所有捕获的圆背虾虎鱼的体长与体重测量数据；第四张表格"SiteData"收录12个研究采样点的基础信息。本数据集首次发布于2020年11月，版本号1.0；2024年5月完成修订，版本号2.0。
