摘要

的目标。本研究的目的是研究塞万湖流域的鱼类蠕虫区系。材料和方法。从塞万湖盆地采集了鱼类、蠕虫和软体动物。共研究了214种鱼类标本。材料的采集、照相处理和测定均按普遍接受的方法进行。使用BioStat 2009计算机程序对材料进行统计处理。从塞万湖沿岸采集了124个软体动物标本。软体动物的采集和鉴定是按照普遍接受的方法进行的。这项工作是在亚美尼亚共和国国家科学院动物学和水文生态学科学中心进行的。它自己的收藏品被用作材料。结果。在对塞万湖流域鱼类的研究中发现了吸虫、绦虫、线虫和棘头虫。虫蛀率为27.1%。已经确定了六种蠕虫,其中两种是在亚美尼亚新宿主中首次记录的。鱼类侵染率较高的是吸虫的囊蚴和肠虫的破尾蚴。对检测到的蠕虫对鱼类的危害作了简要分析。结论。对塞万湖流域鱼类蠕虫区系的种类组成进行了研究。引起鱼类死亡的危险蠕虫病病原体已被注意到。对塞万湖流域鱼类的蠕虫动物群的研究是相关的,并将继续进行。大多数受蠕虫影响的鱼类具有重要的经济价值。发现的一些种类的蠕虫具有很强的侵入性,对共和国的渔业造成了很大的损害。

The fish helminth fauna of Lake Sevan during a period of water level change
Aim . The aim of the work is to study the fish helminth fauna of Lake Sevan basin. Material and Methods . Fish helminths and molluscs were collected from the Lake Sevan basin. A total of 214 specimens of fish were studied. The collection, cameral processing and determination of the material was carried out according to generally accepted methods. Statistical processing of the material was carried out using the BioStat 2009 computer program. 124 specimens of molluscs were examined from the littoral of the Lake Sevan. The collection and identification of molluscs was carried out according to generally accepted methods. The work was carried out at the Scientific Centre of Zoology and Hydroecology of NAS of the Republic of Armenia. Its own collections have been used as material. Results . Trematodes, cestodes, nematodes and acanthocephals were found аs a result of studies of fish from the Lake Sevan basin. The total infestation of the fish by helminths was 27.1 %. Six species of helminths have been identified, two of which are the first to be recorded in new hosts in Armenia. The higher infestations of fish were noted by metacercariae of the trematode Diplostomum sp. and plerocercoids of the cestode Ligula intestinalis. A brief analysis of the infestation of fish by the detected helminths is given. Conclusion . The species composition of the helminth fauna of fish in the Lake Sevan basin was studied. Pathogens of dangerous helminthiases causing the death of fish have been noted. Studies of the helminth fauna of fish in the Lake Sevan basin are relevant and will be continued. Most of the species of fish affected by helminths are of economic importance. Some species of the helminths which were found are very invasive and cause great damage to the fisheries of the republic.
