[Metazoan parasites of bream (Abramis brama Linnaeus, 1758) in Lake Durusu (Terkos)].

In this study, metazoan parasites of bream (Abramis brama Linnaeus, 1758) in the Lake Durusu (Terkos) were investigated between June 2002 and May 2003. During this study, a total of 67 bream were examined for the presence of metazoan parasites. Ten species of parasites were found on 64 of the 67 fish examined. These parasites are: Dactylogyrus sphyrna (Linstow, 1878) and D. distinguendus (Nybelin, 1936) Monogenoidea, Caryophyllaeus laticeps (Pallas, 1781) Cestoidea, Tetracotyle sp, Diplostomum sp. and Tylodelphys clavata (Nordmann, 1832) metacercaria Trematoda, Eustrongylides excisus (Jagerskiöld, 1909) Nematoda, Piscicola geometra (Linnaeus, 1758) Hirudinea, glochidia of mollusk, Bivalvia, Argulus foliaceus (L., 1758) Crustacea. Diplostomum sp., Dactylogyrus sphyrna and D. distinguendus were found to be the dominant parasites of A. brama. Both the prevalence and intensity of other parasites were not found to be high. All identified parasites are a new finding for A. brama in the Lake Durusu. This is the first time that D. distinguendus has been identified in Turkey.
