The fauna of parasitic protozoans of the bream (Abramis brama) from different reachs of the Rybinsk water reservoir was investigated. 350 fish specimens have been examined by the method of total dissection. The greater number of parasites and diversity (33 species) were observed in the Volzhski reach: infusoria--16 species, myxosporidia 12, flagellata--4, dermocystidia--1. In the breams of Sheksninski reach 18 species of parasites were recovered: infusoria--8, myxosporidia--8, flagellata--1, dermocystidia--1. Parasite protozoans from the Molozhski reach were represented by 14 species: myxosporidia--8, infusoria--5, flagellata--1. Statistic analysis of the morphological variability of spores of the myxosporidians from gills (Myxobolus muelleri and M. exiguus) has displayed the decrease of spore size in the row Molozhski-Volzhski-Sheksninski reachs. Some parasitic protozoans could be used as indicators of local fish herds.
对雷宾斯克水库不同河段的鲷（Abramis brama）寄生原生动物区系进行了研究。采用全解剖法检查了350份鱼类标本。在伏尔加河段观察到的寄生虫数量最多且种类多样（33种）：纤毛虫——16种，粘孢子虫12种，鞭毛虫——4种，皮囊肿虫——1种。在舍克斯纳河段的鲷中发现了18种寄生虫：纤毛虫——8种，粘孢子虫——8种，鞭毛虫——1种，皮囊肿虫——1种。莫洛日河段的寄生原生动物有14种：粘孢子虫——8种，纤毛虫——5种，鞭毛虫——1种。对鳃部粘孢子虫（Myxobolus muelleri和M. exiguus）孢子形态变异性的统计分析表明，在莫洛日-伏尔加-舍克斯纳河段，孢子大小呈下降趋势。一些寄生原生动物可作为当地鱼群的指标。
