In this study, some biological features of brown comber Serranus hepatus L.,1758 were investigated from İzmir Bay. 1062 specimens were captured by R/V Egesuf by bottom trawl net between January-April 2005. It is determined that the samples of population distributed between 0-III age groups. Minimum, maximum and mean total length were determined as 6.0, 11.6 and 9.51± 0,71 cm, respectively. Minimum, maximum and mean weights were determined as 3.71, 25.49 and 13.04 ± 2,85 g, respectively. The length-weight relationship was determined as W=0.0182*L2.91, r= 0.94. Von Bertalanffy growth parameters were calculated as Lt = 12.52 * [1-e-0.435 (t+1.194)] and Wt= 39.80 * [1-e-0.135 (t+1.035)]2.91 for all specimens. Stomach contents of the species were examined to reveal general feeding habits, and the main preys were found as decapod crustaceans.

İzmir Körfez’inde Dağılım Gösteren Benekli Hani (Serranus hepatus Linnaeus, 1758) Balığının Büyüme ve Beslenme Özellikleri

Öz

Bu çalışmada, İzmir Körfezi’nde benekli hani balığının (Serranus hepatus, L.,1758) yaş, büyüme ve beslenme özellikleri tespit edilmesi hedeflenmiştir. Ocak 2005–Nisan 2005 tarihleri arasında, İzmir Körfezi’nden trol ağı ile aylık olarak toplam 1062 adet S. hepatus elde edilmiştir. Bireylerin 0-III yaş grupları arasında dağılım gösterdiği belirlenmiştir. Minimum, maksimum ve ortalama total boy sırasıyla, 6.0, 11.6 ve 9.51 ± 0,71 cm’dir. Minimum, maksimum ve ortalama ağırlık sırasıyla, 3.71, 25.49 ve 13.04 ± 2,85 g’dır. Total boy-ağırlık ilişkisi esas alınarak hesaplanan boy ağırlık ilişkileri, W=0.0182*L2.91, r= 0.94 olarak tespit edilmiştir. Von Bertalanffy büyüme parametreleri tüm bireyler için Lt = 12.52 * [1-e-0.435 (t+1.194)] ve Wt= 39.80 * [1-e-0.135 (t+1.035)]2.91 olarak hesaplanmıştır. Türün genel beslenme özelliklerini tespit etmek amacıyla mide içeriği incelenmiş ve temel besin grubunun dekapod krustaseler olduğu ortaya çıkmıştır.
