In this study, Craspedacusta sowerbii Lankester, 1880 a jellyfish species belonging to freshwater hydrozoan group, was reported for the first time in the field study carried out at Uzunçayır dam lake in Tunceli province on 15 September 2018. The plankton samples were obtained from two different regions of the lake using UNESCO WP2 plankton net with mesh size of 200 µm. C. sowerbii, one of the fresh water hydrozoans obtained from plankton samples, is rarely observed in man-made lakes, ponds, and reservoirs, and has not been observed earlier in the Uzunçayır dam lake. The C. sowerbii might have placed in the lake through some fishing activities which were conducted from 2010 to 2017 and/or through some sport equipment’s (i.e. boat, jetski, were brought to the region for recreational purposes).

淡水水母Craspedacusta sowerbii Lankester的发生，1800年，来自土耳其Uzunçayır坝湖（通塞利）

在这项研究中，首次报道了2018年9月15日在通塞利省的Uzunçayır坝湖进行的野外研究，首次报道了属于淡水水生动物群的1880种水母种类Craspedacusta sowerbii Lankester。浮游生物样品是从两个不同的地方获得的。在湖区使用联合国教科文组织WP2浮游生物网，网眼尺寸为200 µm。C. sowerbii是从浮游生物样品中获得的淡水水生动物之一，在人造湖，池塘和水库中很少见到，在Uzunçayır坝湖中也未见过。该C. sowerbii 可能是通过2010年至2017年进行的一些捕鱼活动和/或通过某些运动器材（例如，将小船，水上摩托艇带到该地区用于娱乐目的）放置在湖中的。
