Özet

Rainbow trout (Oncorhynchus mykiss) cage-cultured in Kesikkopru Dam Lake were examined for ectoparasites on body surface, gills and fins between December 2004-June 2005. During study period, six parasite genera covering only protozoons were detected. General prevalance of detected parasites was found to be 90%. General parasite prevalence in the present study were as folllows: Trichodina sp.; 85%, Epistylis sp.; 65%, Chilodonella sp.; 25%, Costia sp.; 15%, Apiosoma sp.; 9.5% ve Tripartella sp.; 2.8%, respectively. Mean intensity of parasites were determined as Trichodina sp.; 174.64 +/- 0.85, Costia sp.; 41.75 +/- 0.15, Epistylis sp.; 30.81 +/- 0.65, Tripartiella sp.; 7 +/- 0.028, Chilodonella sp.; 6.18 +/- 0.25, Apiosoma sp.; 2.9 +/- 0.095. Mean abundance of parasites were calculated as follows: Trichodina sp.; 149.54 +/- 0.85, Epistylis sp.; 20.24 +/- 0.65, Costia sp.; 63.69 +/- 0.15, Chilodonella sp.; 1.50 +/- 0.25, Apiosoma sp.; 0.27 +/- 0.095, Tripartiella sp.; 1.4 +/- 0.028. Ectoparasites of rainbow trout cultured at cages in the lakes were firstly described.
