The paper provides data on the invasion of Acipenser ruthenus (sterlet) in the North Dvina River by Polypodium hydriforme (Cnidaria). Prevalence and intensity of invasion proved to be similar for two fishing sites. Prevalence of invasion exceeded 88%, thus being exceptionally high for P. hydriforme. Intensity of invasion was from 1 to 436 eggs per female. A verage percentage of infected eggs was about 1%.
该论文提供了关于多态水螅（刺胞动物门）入侵北德维纳河中的俄罗斯鲟（小体鲟）的数据。两个捕鱼地点的入侵发生率和强度相似。入侵发生率超过88%，这对多态水螅来说异常高。入侵强度为每只雌体1至436枚卵。受感染卵的平均百分比约为1%。
