Název v původním jazyce

Seasonal occurrence and metrical variability of Gyrodactylus rhodei Zitnan, 1964 (Monogenea, Gyrodactylidae)

Popis výsledku v původním jazyce

Gyrodactylus rhodei Zitnan, 1964 is ectoparasite of the bitterling (Rhodeus sericeus Pallas, 1776), living on the gills, fins and body surface. A total of 691 specimens of G. rhodei were collected from July 2000 to May 2001 in River Kyjovka, Czech Republic. The presence of parasites was related to water temperature. The abundance and prevalence tended to increase during the cold period of year, winter and early spring. The abundance and prevalence decreased during the warm period of the year. Variability of attachment parts of parasite haptor was studied on 101 parasite specimens. The hard parts of haptor were significantly smaller in specimens occurring during warm season and vice versa. The negative relationship between water temperature and size ofhard parts of G. rhodei haptor was evident on measurements of total length of marginal hooks, anchors, anchor point and root, length of ventral bar and membrane processes. Also sequences of the compete ITS (rDNA) of specimens from winter
