Abstract

Specimens of the striped red mullet (Mullus surmuletus) were caught monthly by trawl surveys carried out between 2005 and 2007 in Izmir Bay. In this study, age composition, growth parameters and reproduction features of totally 192 individuals were examined. All individuals ranged from 6.6 cm to 22.6 cm in total lengths and from 3.40 g to 166.70 g in total weight. The maximum observed age was 6 for all specimens. The length-weight relationships were estimated as W=0.0083*L3.127 (r=0.980). The von Bertalanffy growth equations for length were found as Lt=27.85 (1-e-0.193 (t+1,578)) for sex combined. The growth performance index value (Φ´) was computed as 2.175 for all specimens. The monthly values of the Gonadosomatic index indicated that spawning occurred in spring.

Özet

Tekir balığı (Mullus surmuletus) örnekleri 2005–2007 yılları arasında İzmir Körfezi’nde aylık olarak gerçekleştirilen trol operasyonlarından elde edilmiştir. Çalışmada, toplam 192 adet bireyin yaş kompozisyonu, büyüme parametreleri ve üreme özellikleri incelenmiştir. Bireylerin total boyları 6.6 cm ile 22.6 cm; ağırlıkları ise 3.40 g ile 166.70 g arasında değişmiştir. Maksimum yaş tüm bireyler için 6 olarak bulunmuştur. Boy-ağırlık ilişkisi W=0.0083*L3.127 (r=0.980) olarak hesaplanmıştır. Boya göre von Bertalanffy büyüme eşitliği; Lt=27.85 (1-e-0.193 (t+1,578)) olarak bulunmuştur. Büyüme performans indeks değeri (Φ´) 2.175 olarak hesaplanmıştır. Aylık gonadosomatik indeks değerleri, yumurtlamanın İlkbahar’da olduğunu göstermiştir.
