Metazoan Parasites of Bleak ( Alburnus alburnus ), Crucian Carp ( Carassius carassius ) and Golden Carp ( Carassius auratus ) in Enne Dam Lake, Turkey

摘要

Three species of fish, namely bleak ( Alburnus alburnus ), Crucian carp ( Carassius carassius ) and golden carp ( Carassius auratus ) were collected from Enne Dam Lake (Turkey) and examined for parasitic infections. The most common fish species was A. alburnus followed by C. carassius and C. auratus . Three species of Monogenea ( Dactylogyrus fraternus , Dactylogyrus alatus and Paradiplozoon homoion ) were recorded from the gills of A. alburnus whilst the monogeneans Dactylogyrus anchoratus and Gyrodactylus katherineri and the nematode Contracaecum sp. were found infecting C. carassius and C. auratus . There was a significant positive correlation between fish length, fish weight and infection rate in Crucian carp . However, no clear correlation existed between length, weight and parasite infections in bleak. In addition, a significant negative correlation was found between water temperature and Contracaecum sp. infections in golden carp.
