Abstract: | A 3 year survey of a lake, in which 120 roach, Rutilus rutilus , were examined revealed the presence of the plerocercoids of Ligula intestinalis in more than 90 % of the fish. The average number of parasites per fish was 4.2 although fish exceeding 32 g were not ligulosed. Gudgeon, Gobio gobio , of all sizes were affected. Implants of the plerocercoids into small roach, gudgeon and goldfish, Carassius auratus , were successful but not in the case of Perca fluviatilis, Esox lucius and Leuciscus cephalus. The pathological effects of the plerocercoids on roach and gudgeon are described. |
