Common carp is infected by five Dactylogyrus spp in both pond and natural lake habi-tats in Iran, namely D. extensus D. anchoratus, D. achmerovi, D. vastator and D. sahuensis. Fry and fingerlings are more sensitive to infection and their sensitivity is increased with the higher density of fishes usually found in ponds. General gill lesions in dactylogyrosis are quite similar but there are few differences in local lesions among Dactylogyrus spp infecting common carp. In this paper, the geographical distribution of Dactylogyrus spp of common carp is presented and the gill histopathology caused by D. sahuensis is described and discussed.
