Özet
The study aimed to identify the digenean metacercariae parasitic in fishes in the Sarikum Lagoon Lake located at the Black Sea coast of Turkey. A total of 906 fish specimens belonging to 6 fish species (Aphanius danfordii, Neogobius melanostamus, Proterorhinus marmoratus, Gasterosteus aculeatus, Platichthys flesus and Chelon auratus) were examined monthly during a period of one year. Four digenean species recorded as encysted metacercariae were identified; these were three species belonging to Heterophyidae, i.e. Ascocotyle coleostoma, Pygidiopsis genata and Cryptocotyle concava, and one species of the family Diplostomatidae, i.e. Posthodiplostomum sp. Ascocotyle coleostoma was found to be the dominant species and detected in all examined fish species. Posthodiplostomum sp. was detected only in A. danfordii. Cryptocotyle concava was detected in N. melanostamus and P. marmoratus. Infection prevalence and intensity were calculated and discussed for each digenean species recorded as metacercariae in relation to season. The eye, heart and gill tissues of infected fish with parasites were examined histologically. The histological evaluation indicated that the histological lesions were more severe in gills.
