Metazoan Parasites of Common Sole () and Scaldfish () (Pleuronectiformes) from Sinop Coast of Black Sea.

The metazoan parasites were investigated of two flatfish the common sole, (n:140) and the scaldfish, (n: 22) in the Sinop coast of Black Sea from June 2015 to June 2017. A total of 15 metazoan parasite species belonging to Digenea (6), Cestoda (3), Acanthocephala (1), Nematoda (4) and Isopoda (1) taxonomic groups were identified. was found to be infected by , , Opecoelidae gen. sp., sp., sp., sp., , , and was found to be infected by and and were determined in both flatfish. Infection prevalence and mean intensity values were recorded for each parasite species. Infection values for each parasite species in relation to season and fish size were also determined and compared as comparatively. This study is the first one assessing the metazoan parasites both of and collected from the Turkish coast of Black Sea. While and are new parasite records for , is new parasite record for . Moreover, this paper is the first report on occurrence of Opecoelidae gen. sp., and genera in .
