Summary The northern section of the Caspian Sea is an important fishery for Kazakhstan. In the present study, a total of 606 individuals of 13 fish species were collected. For each of Abramis brama, Alosa saposchnikowii, Atherina boyeri caspia, Carassius auratus, Clupeonella cultriventris, Cyprinus carpio, Liza aurata, Leuciscus aspius, Rutilus rutilus caspius, Sander lucioperca, Sander marinus, and Sander volgensis 50 individuals were examined whilst 6 individuals of Siluris glanis were examined. The nematode parasite Anisakis schupakovi was found in all fish species except Liza aurata, Carassius aurata, Cyprinus carpio and Rutilus rutilus at intensities ranging from 1 to 1197 parasites per infected fish. Trematodes of family Diplostomidae were also isolated from all fish except Alosa saposhnikowii, Clupeonella cultriventris and Sander marinus at intensities ranging from 1 to 242 parasites per infected fish. Other parasites found included the nematodes Porrocaecum reticulatum, Contracecum sp, Camallanus sp and Eustrongylus excisus; the cestodes Neogryporhynchus cheilancristrotus, Bothriocephalus opsariichthydis; the monogenean parasites Mazocraes alosa, Ancyrocephalus paradocus, Gyrodactylus spp, Ligophorus vanbenedenii and Dactylogyrus spp; and the crustacean parasites Ergasilus sp. and Synergasilus sp. In addition one unidentified species of nematode and a bivalve of the genus Unio was recovered from Rutilus rutilus caspius. There was no association between Fulton’s condition index and intensity of parasite infection.

里海哈萨克斯坦部分及相关流域鱼类的蠕虫寄生虫

总结 里海北部是哈萨克斯坦的重要渔业。在本研究中，共收集了 13 种鱼类的 606 只个体。对于 Abramis brama、Alosa saposchnikowii、Atherina boyeri caspia、Carassius auratus、Clupeonella cultriventris、Cyprinus carpio、Liza aurata、Leuciscus aspius、Rutilus rut​​ilus caspius、Sander lucioperca、Sander marinus 和 Sander60 个体，同时检查了 50 个个体检查了龟头。在除 Liza aurata、Carassius aurata、Cyprinus carpio 和 Rutilus rut​​ilus 之外的所有鱼类中都发现了线虫寄生虫 Anisakis schupakovi，其强度范围为每条受感染的鱼 1 至 1197 个寄生虫。除 Alosa saposhnikowii 外，还从所有鱼类中分离到了 Diplostomidae 科的吸虫，Clupeonella cultriventris 和 Sander marinus，强度范围为每条受感染的鱼 1 到 242 个寄生虫。发现的其他寄生虫包括线虫 Porrocaecum reticulatum、Contracecum sp、Camallanus sp 和 Eustrongylus excisus；The cestodes Neogryporhynchus cheilancristrotus, Bothriocephalus opsariichthydis; 单系寄生虫 Mazocraes alosa、Ancyrocephalus paradocus、Gyrodactylus spp、Ligophorus vanbenedenii 和 Dactylogyrus spp；和甲壳类寄生虫 Ergasilus sp。和 Synergasilus sp。此外，从 Rutilus rut​​ilus caspius 中还发现了一种未鉴定的线虫物种和 Unio 属的一种双壳类动物。富尔顿的病情指数与寄生虫感染强度之间没有关联。发现的其他寄生虫包括线虫 Porrocaecum reticulatum、Contracecum sp、Camallanus sp 和 Eustrongylus excisus；绦虫 Neogryporhynchus cheilancristrotus, Bothriocephalus opsariichthydis; 单系寄生虫 Mazocraes alosa、Ancyrocephalus paradocus、Gyrodactylus spp、Ligophorus vanbenedenii 和 Dactylogyrus spp；和甲壳类寄生虫 Ergasilus sp。和 Synergasilus sp。此外，还从 Rutilus rut​​ilus caspius 中回收了一种未鉴定的线虫物种和一种 Unio 属双壳类动物。富尔顿的病情指数与寄生虫感染强度之间没有关联。发现的其他寄生虫包括线虫 Porrocaecum reticulatum、Contracecum sp、Camallanus sp 和 Eustrongylus excisus；The cestodes Neogryporhynchus cheilancristrotus, Bothriocephalus opsariichthydis; 单系寄生虫 Mazocraes alosa、Ancyrocephalus paradocus、Gyrodactylus spp、Ligophorus vanbenedenii 和 Dactylogyrus spp；和甲壳类寄生虫 Ergasilus sp。和 Synergasilus sp。此外，从 Rutilus rut​​ilus caspius 中还发现了一种未鉴定的线虫物种和 Unio 属的一种双壳类动物。富尔顿的病情指数与寄生虫感染强度之间没有关联。Ligophorus vanbenedenii 和 Dactylogyrus spp；和甲壳类寄生虫 Ergasilus sp。和 Synergasilus sp。此外，从 Rutilus rut​​ilus caspius 中还发现了一种未鉴定的线虫物种和 Unio 属的一种双壳类动物。富尔顿的病情指数与寄生虫感染强度之间没有关联。Ligophorus vanbenedenii 和 Dactylogyrus spp；和甲壳类寄生虫 Ergasilus sp。和 Synergasilus sp。此外，从 Rutilus rut​​ilus caspius 中还发现了一种未鉴定的线虫物种和 Unio 属的一种双壳类动物。富尔顿的病情指数与寄生虫感染强度之间没有关联。
