[An investigation of metazoan parasites of common Carp (Cyprinus carpio L.) in Lake Eber, Afyon, Turkey.].

In this study, metazoan parasites of the following fish species were investigated in Lake Eber (Afyon) from July 2002-2003. At the end of this research, 2 species of Monogenea (Gyrodactylus elegans, Dactylogyrus extensus) were found on the gills and fins of the fishes; 1 species of Digenea (Posthodiplostomum cuticola), on skin and fins; 1 species of Cestoda (Bothriocephalus acheilognathi) in the intestines; and 1 species of Arthropoda (Argulus foliaceus), the skin, gills and fins of fish. The distribution of these parasites in various fish species are given below: The distribution of these parasites are as follows: 3456 Gyrodactylus elegans in 51 specimens of common carp (67.1% prevalence, 67.75+/-162.52 parasite/fish); 2980 Dactylogyrus extensus (73.6%, 53.21+/-52.95) in 56 specimens of common carp; 55 Posthodiplostomum cuticola (18.4%, 3.93+/-5.42) in 14 specimens of common carp; 1240 Bothriocephalus acheilognathi (43.4%, 37.55+/-53.98) in 33 specimens of common carp and 6 Argulus foliaceus (6.5%, 1.20+/-0.44); in 5 specimens of common carp.
