Karamenderes Çayı’nda (Türkiye) İstilacı Gümüşi Havuz Balığının (Carassius gibelio, Bloch 1782) Beslenmesindeki Ontogenetik Değişim

Öz

Bu çalışmada Karamenderes Çayı’nda bulunan istilacı Carassius gibelio (Bloch, 1782) türünün beslenmesindeki ontogenetik değişimin belirlenmesi amaçlanmıştır. Arazi çalışmaları Yaz 2012, Sonbahar 2012 ve İlkbahar 2013 mevsimlerinde gerçekleştirilmiştir. Balıkların yakalanmasında elektroşoker ile çeşitli ağlar kullanılmıştır. Beslenmedeki ontogenetik değişimi belirlemek için, balıklar çatal boylarına göre dokuz gruba ayrılmıştır. Balıkların sindirim kanalı içerikleri besin bulunma sıklığı, sayısal bolluk ve hacimsel oran kullanılarak nisbi önem indeksi ile hesaplanmıştır. C. gibelio bireylerinin mevsimlere göre bol olan boy grupları sırasıyla Yaz 2012 (18-20 cm), Sonbahar 2012 (6-8 cm) ve İlkbahar 2013 (27-29 cm) şeklindedir. Beslenme şiddeti Yaz 2012’de 15-17 cm, Sonbahar 2012’de 3-5 cm ve İlkbahar 2013’de 24-26 cm boy gruplarında en az olduğu belirlenmiştir. C. gibelio bireylerinin ontogenetik beslenme alışkanlığında zamansal ve mekânsal olarak farklılıklar gözlenmiştir. Büyük bireyler yaz mevsiminde daha çok hayvansal besin ve sonbahar mevsiminde alglerle beslendiği ve küçük bireylerle büyük bireylerin besinleri arasında yaz mevsimi haricinde önemli bir çakışma olmadığı belirlendi. Küçük ve büyük bireylerin besinleri arasında herhangi bir çakışmanın olmaması, gümüşi havuz balığının Karamenderes’de yerleşme başarısı için bir avantajı olabilir.

Ontogenetic Diet Shift of Invasive Gibel Carp (Carassius gibelio, Bloch 1782) in Karamenderes River (Turkey)

Öz

The ontogenetic diet shift of invasive Carassius gibelio (Bloch, 1782) was investigated in Karamenderes River, Turkey. The fieldwork was performed during summer 2012, autumn 2012 and spring 2013. The fishes were caught by electrofishing and using gill nets. Nine fork length groups were used in order to assess the ontogenetic diet shift. The gut contents were assessed by the index of relative importance that was calculated from the frequency of occurrence, numerical abundance, and volumetric analyses. The most abundant length groups of C. gibelio were 18-20 cm, 6-8 cm, and 27-29 cm length groups during summer 2012, autumn 2012 and spring 2013, respectively. The feeding intensity was the lowest in the length groups of 15-17 cm during summer 2012, in 3-5 cm length group in autumn 2012 and in 24-26 cm length group in spring. Seasonal variations were observed in the ontogenetic diet shift of C. gibelio. Large specimens consumed more animal materials during summer and more algae in autumn. There was not any significant niche overlap recorded between small and large specimens except summer. Any niche overlap between small and large specimens might be advantageous for the establishment success of invasive Gibel carp in Karamenderes River.
