Abstract

In this study, the digestive system contents of 110 crayfish (Astacus leptodactylus) caught from Cip Fish Production and Breeding Centre of Fırat University between December 2001-November 2002 have been examined. In the content of digestive system of examined crayfish, Cyanophyta (10 taxa), Bacillariophyta (16 taxa) and Chlorophyta (13 taxa) belong to plants and Rotifera (10 taxa), Cladocera (3 taxa) and Copepoda (1 taxon) belong to animals have been found. The seasonal, annual and weight groups distribution of the organisms were examined by using numerical method and frequency of occurrence method. At the end of study, the rations in total organism number were Bacillariophyta (68.27 %), Chlorophyta (10.83 %), Cyanophyta (9.94 %), Rotifera (9.45 %), Cladocera (1.14 %) and Copepoda (0.37 %) respectively. It has been observed that Synedra (76.36 %) in respect df occurrence frequency, Gomphonema (18.13 %) in respect of invidual numbers were showed the highest values within all observed organisms in digestive system.

Özet

Bu çalışmada, Aralık 2001-Kasım 2002 tarihleri arasında Fırat Üniversitesi Cip Balık ve Yetiştirme Tesisleri' nden yakalanan toplam 110 kerevit (Astacus leptodactylus)' in sindirim aygıtı içeriği incelenmiştir. İncelenen kerevitlerin sindirim aygıtı içeriğini bitkisel organizmalardan Cyanophyta (10 takson), Bacillariophyta (16 takson) ve Chlorophyta (13 takson); hayvansal organizmalardan ise Rotifera (10 takson), Cladocera (3 takson) ve Copepoda (l takson)' nın oluşturduğu bulunmuştur. Sayısal ve bulunuş frekansı yöntemleri kullanılarak besinsel organizmaların mevsimsel, yıllık ve ağırlık gruplarına göre dağılımları incelenmiştir. Çalışma sonucunda sayısal olarak toplam organizmayı sırasıyla, Bacillariophyta (%68,27), Chlorophyta (%10,83), Cyanophyta (%9,94), Rotifera (%9,45), Cladocera (%1,14) ve Copepoda (%0,37)' nın oluşturduğu, bulunuş frekansı yüzdesi bakımından en fazla bulunan organizmanın Synedra (% 76,36), sayısal yüzde bakımından ise en fazla bulunan organizmanın Gomphonema (% 18,13) olduğu saptanmıştır.
