Gnathia sp. (Gnathiidae) infestations on marine fish species from Turkey.

This study was carried out between June and August 2006. Totally 150 samples out of ten different fish species caught from the Marmara Sea, the Black Sea and the Aegean Sea were examined. For this purpose, body surface, fins, gills and mouth cavity of each fish were examined with the aid of a dissecting microscope. After that, ectoparasite samples were preserved in 70% ethanol to be observed under the dissecting microscope for identification. Gnathia sp. was found out in the mouth cavity and gill flaments of these infected fishes. This is the first study reporting Gnathia sp. from Serranus cabrilla; Mullus surmuletus; Mugil cephalus; Trachurus mediterraneus, Sarpa salpa; Sciaena umbra.
