Gnathia sp. (Gnathiidae) ınfestations on Marine fish species from Turkey

Bu çalışma Haziran-Ağustos 2006 periyodunda yapılmıştır. Marmara Denizi, Karadeniz ve Ege Denizi’nden yakalanan 10 farklı balık türünden toplam 150 balık incelenmiştir. Bu amaçla her bir balığın vücut yüzeyi, yüzgeçleri, solungaçları ve ağız boşluğu disseksiyon mikroskobu ile incelenmiştir. Bundan sonra ektoparazit örnekleri disseksiyon mikroskobu altında incelenmiş olup, toplanan balıkların teşhis edileceği zamana kadar %70’lik etanolde muhafaza edilmiştir. Gnathia sp. larvalarına enfekte balıkların solungaç flamentleri ve ağız boşluklarında rastlanmıştır. Bu çalışmayla Türkiye’de Serranus cabrilla; Mullus surmuletus; Mugil cephalus; Trachurus mediterraneus; Sarpa salpa; Sciaena umbra balık türlerinden Gnathia sp. ilk defa rapor edilmektedir.

Türkiye Deniz balığı türlerinde Gnathia sp. (Gnathiidae) infestasyonu

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.
