Occurrence of Dactylogyrus species (Platyhelminths, Monogenean) on Cyprinids in Almus Dam Lake, Turkey

Dactylogyrus cinsi parazitler birçok balık türünü enfekte eden en genişhelmit cinsidir. Türkiye’de bulunan tatlı su balıklarının tür zenginliğini düşünecek olursak, Türkiye tatlısu balıklarında yeterli sayıda çalışma bulunmamaktadır. Bu nedenden dolayı, bu çalışma dört tatlı su balığı türünde bulunan Dactylogyrus türlerinin çeşitliliği, mevsimsel değişim ve konak balık büyüklüğüne bağlı değişimi belirlemek amacı ile yapılmıştır. Bu çalışmada Barbus plebejus’tan D. malleus, Alburnus orontis’ ten D. alatusf.major, Chondrostoma regium’ dan D. vistulae ve D. alatusf.major, Leuciscus cephalus’ tan D. naviculoidesveD. vistulaeolmak üzere toplam 4 Dactylogyrus türü tespit edilmiştir. Bu türlerden D. malleus, D. alatusf. major ve D. naviculoides Türkiye tatlısu balıklarından ilk defa bildirilmektedir. Dört balık türünde bulunan Dactylogyrus türlerinin mevsimsel dağılımındaki farklılıklar bu çalışmada sunulmuş. Genel olarak, parazit yaygınlığı ve yoğunluğu en yüksek bahar ve yaz, sonra sonbahar aylarında bulunmuştur.

Almus Baraj Gölü (Türkiye)n’deki sazangiller’de bulunan Dactylogyrus türleri (platyhelminths, monogenean)

The genus Dactylogyrus is the largest helminth genus parasitizing many fish species. Considering species richness of freshwater fish in Turkey, there are inadequate studies in Turkish freshwater fish. Therefore, a survey of Dactylogyrus species from four freshwater species was carried out to determine parasite diversity, the changes in their seasonal variation and host size dependent variability. A total of 4 Dactylogyrus species were found; these were D. malleus from Barbus plebejus, D. alatusf. major from Alburnus orontis, D. vistulae and D. alatusf.major from Chondrostoma regium, D. naviculoides and D. vistulae from Leuciscus cephalus. However, to our knowledge, this is the first time D. malleus, D. alatusf. major and D. naviculoides have been reported from Turkish freshwater fish. In general, prevalence and intensity of Dactylogyrus species were higher in spring and summer than autumn.
