[An investigation of parasites of goldfish (Carassius carassius L., 1758) in Kovada Lake.].

The aim of this study, carried out from 25.03.2003-17.02.2004, was to determine the ectoparasites and endoparasites of goldfish (Carassius carassius L., 1758) inhabiting Kovada Lake. A total of 102 specimens were caught monthly and investigated parasitologically. As a result of the investigation, the ectoparasites, Dactylogyrus anchoratus, Dactylogyrus minutus, Argulus foliceaus and Trachellobdella torquata, and the endoparasite Contracaecum sp. were found in the goldfish. Among these, Dactylogyrus minutus and Trachellobdella torquata have been recorded for the first time in goldfish in Turkey.
