Relative importance of food items in feeding of Chondrostoma regium Heckel, 1843, and its relation with the time of annulus formation

Öz:
Bu çalışmada, kababurun balığı (Chondrostoma regium Heckel, 1843)'nın tükettiği besin çeşitlerinin nisbi önemini analiz etmek amaçlanmoştor. 145 kababurun baloğo örneği Nisan 1993 - Mart 1994 tarihleri arasonda Suat Uğurlu Baraj Gölü'nden yakalanmıştır. Kabababurun balığının besin olarak tükettiği organizmaları tanımlamak için mide içeriği analiz metodu kullanılmıştır. Besin miktarlar ının nisbi ölçümleri iki farklı yaklaşımla hesaplanmıştır. Bunlar; nisbi önem indeksi (IRI) ve geometrik önem indeksleridir (GII). Bu bileşik indislerden elde edilen sonuçlar karşılaştırılmış ve besin tercihi için en güvenilir hesaplama yöntemi tartışılmıştır. Navicula, Cymbella ve Synedra en fazla tüketilen organizma olarak tespit edilmiştir. Kababurun balığı genellikle Bacillariophyta ile beslenen planktivor bir balıktır. Ayrıca, besin tercihindeki mevsimsel değişimler incelenmiş ve yaşla ilişkisi araştırılmış, kemiksi yapılardaki annulus oluşum periyodu ve beslenme aktivitesi arasındaki ilişki incelenmiştir. Sonbaharda besin çeşitlerindeki azalmayla birlikte hyalin halkaların oluştuğu tespit edilmiştir.

In this study, we analyzed the relative importance of food items of Chondrostoma regium Heckel, 1843. A total of 145 individuals were sampled between April 1993 and March 1994 in Suat Uğurlu Dam Lake. Stomach content analysis was used to determine dietary composition. Relative measures of food item quantity were estimated by two different approaches: the Index of Relative Importance (IRI) and the Geometric Index of Importance (GII). The results from these indices were compared and the most reliable way of estimating dietary composition was discussed. Navicula, Cymbella and Synedra were the most frequently consumed organisms. As C. regium mostly feeds on Bacillariophyta, it can be defined as planktivorous. Furthermore, ontogenic variations and the seasonal variation of food consumption were examined. The relation between the time of annulus formation on bony structures and feeding activity were also investigated. The deposition of hyaline rings were found to be synchronous with decrease in food diversity in autumn.
