Fish were collected by commercial fishermen in Sinop coastsof the Black Sea in April and May 2014. Infection prevalence and mean intensityvalues were determined as 12.5% and 2.00 ± 0.0 in shore rockling; 4.76% and1.00 ± 0.0 in Atlantic horse mackerel; 20.0% and 6.80 ± 3.20 in botchedpicarel; 20.00% and 4.00 ± 0.0 in grass goby and, 1.44% and 55.00 ± 0.0 inround goby. Our results showed that this parasite species can be found widely atits larval stage in many bony fish species in the Black Sea.Buarastirmada, Nisan-Mayis 2014 tarihlerinde Karadeniz’in Sinop kiyilarindabalikçi tekneleri ile avlanan Gelincik baligi (Gaidropsarus mediterraneus), Istavrit baligi (Trachurus trachurus), Izmarit baligi (Spicara flexuosa), sazkayasi baligi (Zosterissesor ophiocephalus), Kum kaya baligi (Neogobius melanostomus) mide - bagirsak sistemleri birtetraphylleadean larval sestod olan Scolexpleuronectis Müller, 1788 enfeksiyonlari arastirildi. Enfeksiyon orani veenfekte balik basina ortalama parazit sayilari Gelincik baligi % 12.5 ile 2.00± 0.0; Istavrit baligi % 4.76 ile 1.00 ± 0.0; Izmarit baligi % 20.0 ile 6.80 ±3.20; sazkayasi baligi % 20.00 ile 4.00 ± 0.0 ve kum kayasi baligi % 1.44 ile55.00 ± 0.0 olarak hesaplandi. Elde ettigimiz bulgular bu parazitinKaradeniz’deki bir çok kemikli balik türlerinde yaygin olarak bulunabildiginigöstermistir.eninfo:eu-repo/semantics/openAccessScolex pleuronectisCestodaSinopBlack SeaArticle21150158
