Özet
Bu çalışmada, beslenme alışkanlıklarını belirlemek için Nisan 2004 ve Mart 2005 tarihleri arasında Beyşehir Gölü (Türkiye)’nden yakalanan 188 adet Kadife Balığı (Tinca tinca L., 1758)’nın sindirim kanalı incelenmiştir. Balıkların sindirim kanalında fitoplanktonik ve zooplanktonik organizmalar, böcekler, detritus (bitkisel ve hayvansal) ve kadife balığında en yaygın iki parazit türü olan Ligula intestinalis ve Asymphylodora tincae tespit edilmiştir. Mevsimler arasında Chlorella, Coscinidiscus, Fragilaria, Mougetia, Phytoconis, Pinnularia, Rivularia, Synedra, Ulotrix, Brachionus, Gammarus sp., ve Ligula intestinalis’in bulunma sıklıkları arasında önemli bir fark mevcuttur (df=3, P<0,05). Bu cinslerden yalnızca 6 tanesi (Chaetophora, Coscinidiscus, Phytoconis, Surirella, Synedra, Daphnia) yaş sınıfları arasında önemli bir farka sahipti (df=5, P<0,05). Ayrıca, 188 kadife balığından 5 tanesinin (%2,66) sindirim kanalının hemen, hemen boş olduğu bulunmuştur. Bu çalışmada, algler ve makrofitlerin en çok tercih edilen besin tipi olduğu, bunu zooplanktonlar ve böcek larvalarının takip ettiği tespit edilmiştir.
In this study, alimentary canal contents of 188 tench (Tinca tinca L., 1758) caught from Beyşehir Lake (Turkey) between April 2004 and March 2005 were examined for feeding habits. Phytoplanktonic and zoooplanktonic organisms, insects, detritus (animal and vegetable) and two most common parasites of tench, Ligula intestinalis and Asymphylodora tincae were determined in observed in the alimentary canal of fish. There was a significant difference between the frequency of the existance of Chlorella, Coscinidiscus, Fragilaria, Mougetia, Phytoconis, Pinnularia, Rivularia, Synedra, Ulotrix, Brachionus, Gammarus sp., and Ligula intestinalis among seasons (df=3, P<0.05). Only 6 of these genera (Chaetophora, Coscinidiscus, Phytoconis, Surirella, Synedra, Daphnia) had a significant difference among age classes (df=5, P<0.05). Additionally, it was found that only 5 of the 188 tench (2.66%) were observed to have almost empty alimentary canal. Algae and macrophytes were found to be the most considerable food types in the present study, which is followed by zooplankton and insect larvae.
