The leaping mullet Chelon saliens is one of the economically significant fish species and the revealing its parasite fauna in relation with some ecological and host related factors will provide new data for our current knowledge. A total of 165 leaping mullet were collected from Sinop coasts of the Black Sea in the period from September 2015 to August 2016 and investigated for parasites. Eleven parasite species including Myxobolus parvus, Myxobolus sp., Sphaerospora mugilis (Myxozoa), Ligophorus szidati, Solostamenides mugilis (Monogenea), Schikhobalotrema sparisomae, Saccocoelium tensum, Saccocoelium obesum (Digenea), Hysterothylacium aduncum (Nematoda), Neoechinorhynchus sp. (Acanthocephala) and Ergasilus lizae (Copepoda) have been identified. The overall infection prevalence, mean intensity and mean abundance values were 65.5%, 26.2 and 17.2, respectively. The overall infection prevalence was dominated by L. szidati, followed by M. parvus and Digenea-group. On the other hand, the overall mean intensity values were dominated by Digenea-group, followed by L. szidati and E. lizae, respectively, while the mean abundance values were dominated by L. szidati, followed by Digenea-group and E. lizae. The infection indices of all identified parasites were also calculated in relation with length classes and sex of fish as well as season and the differences were evaluated statistically. Seasonally significant differences in the infection prevalence and mean abundance were found for Digenea-group, Ligophorus szidati and Neoechinorhynchus sp. These differences were also significant in the length classes of Digenea-group and Ligophorus szidati. This study is the first investigation on seasonal and host related dynamics of parasites of C. saliens in the southern coasts of the Black Sea and all investigated factors were found to influence the infection indices of dominating parasite species.
跳鲈 Chelon saliens 是一种具有重要经济意义的鱼类，揭示其寄生虫区系与一些生态和宿主相关因素的关系将为我们现有的知识提供新的数据。2015 年 9 月至 2016 年 8 月期间，从黑海辛奥普海岸共采集了 165 条跳鲈进行寄生虫调查。共发现 11 种寄生虫，包括 Myxobolus parvus、Myxobolus sp.、Sphaerospora mugilis（粘孢子虫）、Ligophorus szidati、Solostamenides mugilis（单殖吸虫）、Schikhobalotrema sparisomae、Saccocoelium tensum、Saccocoelium obesum（吸虫）、Hysterothylacium aduncum（线虫）、Neoechinorhynchus sp.（棘头虫）和 Ergasilus lizae（桡足类）。总感染率、平均强度和平均丰度值分别为 65.5%、26.2 和 17.2。总感染率以 L. szidati 为主，其次是 M. parvus 和吸虫类群。另一方面，总平均强度值以吸虫类群为主，其次是 L. szidati 和 E. lizae，而平均丰度值以 L. szidati 为主，其次是吸虫类群和 E. lizae。还计算了所有鉴定寄生虫的感染指数与鱼的长度类和性别以及季节的关系，并对差异进行了统计学评估。季节变化对吸虫类群、Ligophorus szidati 和 Neoechinorhynchus sp. 的感染率和平均丰度有显著影响。这些差异在吸虫类群和 Ligophorus szidati 的长度类中也很显著。本研究首次调查了黑海南部沿海跳鲈的寄生虫季节性和宿主相关性动态，所有调查因素均被发现影响主要寄生虫种的感染指数。
