Abstract

In this study, gastric contents of the medusa Rhizostoma pulmo distributed along the Samsun coast of the Black Sea were investigatedbetween August 2008 and January 2010. Moreover, the relationship between the umbrella diameter and prey selectivity was determined.Captured R. pulmo individuals during the sampling period varied from 14.5 to 42.5 cm in umbrella diameter. The largest umbrella diameterwas observed in October in both periods of the present study. Gastric contents of total 231 R. pulmo individuals have been gathered duringthe sampling period from all stations. 31 taxa, 10 larvae, 2 nauplii and fish and Copepod eggs from 11 phyla have been identified in the gastriccontents of R. pulmo individuals. It has been detected that, feeding choices of R. pulmo individuals have differentiated and their food counthas increased due to increasing umbrella diameter (according to Spearman rank correlation, r=0.70; p

Özet

Bu çalışmada Karadeniz’in Samsun kıyıları boyunca dağılan Rhizostoma pulmo medüzünün mide içeriği Ağustos 2008 ile Ocak 2010 arasında araştırılmıştır. Ayrıca şemsiye çapı ve av seçiciliği arasındaki ilişki belirlenmiştir. Örnekleme dönemi boyunca yakalanan R. pulmo bireylerinin şemsiye çapı 14,5 ila 42,5 cm arasında değişmiştir. En büyük şemsiye çapı, bu çalışmanın her iki döneminde de Ekim ayında gözlenmiştir. Örnekleme döneminde tüm istasyonlardan toplam 231 R. pulmo bireylerinin mide içerikleri toplanmıştır. R. pulmo bireylerin mide içeriğinde 31 takson, 10 larva, 2 adet nauplii ve 11 adet filumdan balık ve Copepod yumurtaları tespit edilmiştir. R. pulmo bireylerin beslenme tercihlerinin farklılaştığı ve artan şemsiye çapına göre besin sayısının arttığı tespit edilmiştir (Spearman rank korelasyonuna göre, r = 0,70; p
