Taxonomic evaluations are needed to accurately determine the host selection of fish parasites. The present study is a multidisciplinary research in the field of basic and fish diseases sciences. The description of the hybrid species of and and infection of in these hybrid fish were reported for the first time from the Kürtün Dam Lake in northeast Turkey. A total of 450 fish were sampled in March, August, and October in 2020 using gillnets. Detailed morphological characteristics (n = 24) were compared to determine the difference among ancestors and hybrid species. The prevalence of between the sampling periods and the size groups of fish (0 - 10, 11 - 15, and ≥16 cm in length) were examined. Moreover, the highest prevalence of the parasite was observed in October (78.94 %), with a size range of 0 - 10 cm in length (77.8 %). In addition, the total prevalence of the parasite was 48.44 %. The results revealed that most of the diagnostic metric and meristic features of hybrid fish were ranging between the data of and . According to previous reports, when hybrid individuals were compared with their ancestors in terms of prevalence, hybrid individuals were more susceptible to infections. This study was unique as it provided the first record of in a hybrid fish population.
需要进行分类学评估，以准确确定鱼类寄生虫的宿主选择。本研究是基础和鱼类疾病科学领域的多学科研究。首次从土耳其东北部的库尔通大坝湖报道了[两种鱼]的杂交物种描述以及这些杂交鱼中[某种寄生虫]的感染情况。2020年3月、8月和10月使用刺网共采集了450条鱼。比较了24个详细的形态特征，以确定祖先和杂交物种之间的差异。研究了采样期之间以及鱼的不同大小组（体长0 - 10厘米、11 - 15厘米和≥16厘米）中[该寄生虫]的感染率。此外，在10月观察到该寄生虫的最高感染率（78.94%），体长范围为0 - 10厘米（77.8%）。另外，该寄生虫的总感染率为48.44%。结果表明，杂交鱼的大多数诊断指标和可数特征介于[两种祖先鱼]的数据之间。根据先前的报告，当将杂交个体与它们的祖先在感染率方面进行比较时，杂交个体更容易感染[该寄生虫]。本研究具有独特性，因为它首次记录了杂交鱼群体中[该寄生虫]的情况。
