Stomach contents of the Lesser Spotted Dogfish, (Scyliorhinus canicula (Linnaeus, 1758)) inhabiting Northeastern Mediterranean
Abstract
In this study, stomach contents of 604 specimens of Scyliorhinus canicula (Linnaeus, 1758) obtained from the Northeastern Mediterranean between May 2012- March 2014 were examined to determine diet regime. 482 of the sampled fish (79.8%) had stomachs containing food. For each prey group, percentage numerical presence, percentage weight, frequency of occurrence and relative importance index (% IRI) values were calculated. The most important prey groups for S. canicula living in the Northeastern Mediterranean were Crustaceans and fishes (with IRI= 50.08% and IRI = 46.7% respectively). The second group was Cephalopods with IRI = 2.3 %. Spinculidae (IRI = 0.92%) was the rare prey group.

Kuzeydoğu Akdeniz Bölgesi’nde yaşayan Benekli Kedibalığı, (Scyliorhinus canicula (Linnaeus, 1758))’nın mide içeriği
Abstract
Bu çalışmada; Kuzeydoğu Akdeniz bölgesinde yaşayan Scyliorhinus canicula (Linnaeus, 1758) bireylerinin beslenme rejimi belirlemek için Mayıs 2012-Mart 2014 tarihleri arasında avlanan 604 balığın mide içerikleri incelenmiştir. Bu balıklardan 482 (%79,8)’sinin midesi dolu olarak bulunmuştur. Tespit edilen besin gruplarının sayıları, ağırlıkları, bulunuş frekansları ve nispi önemlilik indeksleri (% IRI) hesaplanmıştır. Sonuç olarak, Kuzeydoğu Akdeniz bölgesinde yaşayan S. canicula bireylerinde kabuklular ve balıklar en önemli besin grupları (sırasıyla %IRI = 50,08 ve %IRI =46,7) olarak bulunmuştur. Kafadanbacaklılar ikincil besin grubunu (%IRI =2,3) oluşturmuşlardır. Spinculidae (%IRI =0,92) ise nadir besin grubudur.
