Dactylogyrus cornu Linstow, 1878 (Monogenea) infestations on vimba (Vimba vimba tenella (Nordmann, 1840)) cought in the Sinop region of Turkey in relation to the host factors

Nispeten az bilinen bir monogenean olan Dactylogyrus cornu Linstow, 1878'in Türkiye'nin Sinop bölgesindeki Karadeniz'e dökülen küçük bir derede bulunan eğrez balığı Vimba vimba tenella Nordmann, 1840'taki infestasyonu araştırıldı. Haziran 2000 tarihinde toplam olarak 122 adet balık incelendi. Ortalama infestasyon oranı ve yoğunluğu, sırasıyla % 100 ve 147,7 ± 7,9 parazit / infekte balık olarak belirlendi. D. cornu konak balığın sadece solungaçlarında bulundu ve sol ve sağ taraftaki solungaç yaylarından sadece ikinci solungaç yayındaki filamentlere olan muhtemel bir yer seçiciliği tespit edildi. Parazitlerin dişi ve daha büyük balıklarda yerleştiği görüldü.

Konakçı faktörlerine bağlı olarak Dactylogyrus cornu Linstow, 1878 (Monogenea)' nın Türkiye' nin Sinop Bölgesinden yakalanan eğrez balığı' ndaki (Vimba vimba tenella (Nordmann, 1840)) enfestasyonu

The infestation by a relatively less known monogenean, Dactylogyrus cornu Linstow, 1878, was investigated on vimba, Vimba vimba tenella Nordmann, 1840 in a small stream pouring into the Black Sea in Sinop, Turkey. A total of 122 fish specimens were examined in June 2000. The overall infestation prevalence and mean intensity levels were 100% and 147.7 ± 7.9 parasites per infested fish, respectively. D. cornu was recorded only on the gills of host fish and possible site specificity to the filaments of the second gill arches of the left and right gill arch sets was recorded. The parasite was also found to be settled more on female and larger host fish.
