COMMON CARP MONOGENIA IN RESERVOIRS OF THE ODESA REGION (UKRAINE).

The article presents data on the distribution of Dactylogyrus and Gyrodastylus in common carp, which depends on the nature of the reservoir and the age of the fish. The highest extensity of damage to carp Dactylogyrus and Gyrodastylus was recorded in Lake Yalpug (42.7%), while in the mouth of the Dniester River it was only 25.4%. In closed reservoirs of the Odesa region (Khadzhibey estuary and Lake Yalpug), Dactylogyrus was most frequently recorded in two-year-old carp with extensiveness indicators of 64.3 and 62.1%, while in the Dniester River the highest extent of invasion was in three-year-old carp (57.9 %). Gyrodastylus was most frequently recorded in three-year-old carp from all reservoirs with a lesion rate of 58.9% to 67.5%. [ABSTRACT FROM AUTHOR]
