Trichodinid fauna of the toothcarp Aphanius danfordii (Boulenger, 1890) (Osteichthyes: Cyprinodontidae), an endemic fish from Sarikum Lagoon Lake in Sinop (Turkey)

Ectoparasitic trichodinids of the toothcarp, Aphanius danfordii (Boulenger, 1890) were investigated during the period from May 2003 to April 2004 in fish collected from Sarikum Lagoon Lake at Sinop, Turkey. A total of three trichodinid species including Trichodina domerguei Wallengren, 1897, Trichodina modesta Lom, 1970 and Tripartiella macrosoma Basson and Van As, 1987 were identified on 423 fish specimens. Photomicrographs and morphometric data were presented for each species. The existence of three trichodinid species in relation to different length classes and the sex of toothcarp as well as their monthly occurences were also investigated and determined. This paper is the first report on the trichodinid fauna present on toothcarp in Turkey. Trichodina modesta and Tripartiella macrosoma were recorded as new records for the parasite fauna in Turkey.
