The relationship between occurrence of ectoparasites, temperature and culture conditions: a comparison of farmed and wild common carp (Cyprinus carpio L., 1758) in the Sinop region of northern Turkey

A 1-year study on the occurrence of ectoparasites on farmed and wild common carp (Cyprinus carpio L., 1758) and their relationship with temperature an d culture conditions was conducted between June 1994 and May 1995 at two si tes in the Sinop region of northern Turkey. Following the investigation of 125 common carp, Trichodina acuta Lom, 1961, Trichodina mutabilis Kazubski and Migala, 1968, Trichodina nigra Lom, 1960, Trichodinella subtilis Lom, 1 959, Apiosoma piscicola Blanchard, 1885, Epistylis sp., Dactylogyrus anchor atus Dujardin, 1845, Dactylogyrus extensus Mueller and Van Cleave, 1932, Gy rodactylus sp. and Argulus foliaceus L., 1758 were identified. Trichodina m utabilis and Dactylogyrus extensus were found to be the most common ectopar asites on both the farmed and the wild common carp. The overall infestation prevalence was 100% on farmed carp and 93.6% on wild carp. Dactylogyrus an choratus represents a new parasite record for Turkey.
