The aim of this study was to determine the rate of helminth infection in rudd, (Scardinus erythrophthalmus L. 1758) between spring and autumn seasons. A total of 87 rudd fish were investigated. Of these, 66 were infected with four species [Dactylogyrus difformis (Monogenea), Diplostomulum spathaceum metacerceria with Asymplodora markewitschi (Digenea), and Hysterothylacium sp. (Nematoda)]. During the study, it was noted that 46 out of 87 hosts were infected with D. difformis . The level of infection for this species was found to be 93% in the spring but it was 13% in the autumn. For D. spathaceum which was the second dominant species, 365 para-sites were found on 71 of 87 hosts. The maximum infection level for this species was 95% in the autumn. A total of 55 A. markewitschi could be found on 3 fish only during the spring. During the study, the lowest infection rate of the four species was that of Hysterothylacium sp. of which only 8 specimens were found on 7 fish.
本研究的目的是确定春季和秋季之间赤睛鱼（Scardinus erythrophthalmus L. 1758）的蠕虫感染率。共调查了87条赤睛鱼。其中，66条感染了四种寄生虫[异形指环虫（单殖吸虫）、带马氏不对称吸虫的匙形双穴吸虫后尾蚴（复殖吸虫）和希氏线虫属（线虫）]。在研究过程中，注意到87条宿主中有46条感染了异形指环虫。该物种的感染率在春季为93%，但在秋季为13%。作为第二优势种的匙形双穴吸虫，在87条宿主中的71条上发现了365个寄生虫。该物种的最高感染率在秋季为95%。仅在春季，在3条鱼上共发现了55条马氏不对称吸虫。在研究过程中，这四种物种中感染率最低的是希氏线虫属，仅在7条鱼上发现了8个标本。
