Metazoan parasites of Alburnus chalcoides in Todurge Lake (Zara/Sivas, Turkey)
Özet
The metazoan parasites of the Danube bleak, Alburnus chalcoides (Guldenstadt, 1772), were determined in Todurge Lake, since the parasite fish fauna had not yet been studied in this system. A total of 106 specimens were collected from October 2004 to September 2005. Six parasite species were found: two monogeneans (Diplozoon paradoxum and Diplozoon megan), one digenean (Posthodiplostomum cuticola), one cestode (Bothriocephalus acheilognathi), one nematod (Rhabdochona sp.), and one copepod (Argulus foliaceus). About 87.7% of the Danube bleak examined were infected by at least one parasite: Rhabdochona sp. (4080 specimens), Posthodiplostomum cuticola (312 specimens) and Diplozoon megan (159 specimens) being the dominant parasites. Only 33% of the fish carried one parasitic species whilst the remainder had two (21.7%), three (17.9%) and four different species (15.1%). The frequency of infestation changed according to seasonal conditions, with a maximum 94.3% observed in spring. Occurrence, density, seasonal changes, and preferences of the parasites species for various ages and size groups of the bleak were identified, despite the limited overall sample size. D. paradoxum, D. megan, P. cuticola, B. acheilognathi, Rhabdochona sp. and A. foliaceus were determined for the first time as parasites of Danube bleak in Turkey. D. megan was also a new record for the fish parasite fauna of Turkey.
