Dactylogyrus minor Wagener, 1857 Locality: canal Kajtor, by lake Velence (County Fejér) Host: Leucaspius delineatus Intensity: 2 This species is a common parasite of the bleak. Its occurrence on Leucaspius delineatus can be regarded as occasional (2 examples altogether). The fact, however, that this species of fish harbours no specific Dactylogyrus parasite, and on its branchiae only Dactylogyrus fraternus which parasitizes also on the bleak, has been registered so far (ZITNAN, 1966), raises the possibility that the Dactylogyrus species of the bleak relatively often establish themselves on Leucaspius delineatus. Dactylogyrus rarissimus Gussev, 1966 Locality: river Danube Host: Rutilus rutilus Intensity: 1-1 In the Carpathian basin this species has been known so far only from the river Latorca. Gyrodactylus stankovici Ergens, 1970 Locality: Pond farms, river Danube Host: Cyprinus carpio Intensity: 3-40 In an earlier study I have pointed out (MOLNÁR, 1968) that on the fins of the carp besides G. katherineri Malmberg, 1969 the occurrence of a parasite of the type G. wage- neri is frequent. This parasite is likely to be identical with the species G. stankovici described by ERGENS (1970) and widely spread in Hungary in natural waters and pond farms.
