Abstract

This study was hold on to determine the lenght, weight, age and sex distributions and growth parameters of European Hake (Merluccius merluccius, L., 1758) in Edremit Bay between August 1999 and December 2000. During the study, A total of 2375 samples which was collected by trawling from the depth strata between 38–80 meters were investigated and the total lenght and weight distrubitions were determined as 7.6-46.2 cm and 2.09-766.0 g respectively. Age determinations based on otolith readings were found that the fishes distributed between 0+ and 5 age groups. The von Bertalanffy growth curve fitted to observed lengths-at-age provided parameters of L=53.49 cm, 47.49 cm and 53.90 cm; k=0.385, 0.349 ve 0.377 year-1; t0=-0.078, -0.112 ve -0.045 year; and the growth performance index value (Φ) was also computed as 2.895, 3.042 ve 3.040 for males, females and all specimens, respectively

Özet

Bu çalışma, Bakalyaro (Merluccius merluccius L., 1758)'nun Edremit Körfezi'ndeki boy, ağırlık, yaş, cinsiyet dağılımları ile büyüme parametrelerinin tespit edilmesi amacıyla Eylül 1999-Aralık 2000 tarihleri arasında yapılmıştır. Çalışma periyodu süresince, 38-80 m derinliklerde yapılmış olan trol çekimlerinden elde edilen toplam 2375 birey incelenmiş ve bu örneklerin 7.6-46.2 cm total boy ve 2.09-766.0 g total ağırlıklar arasında bulunduğu tespit edilmiştir. Otolitlerden yapılan yaş tayinleri sonucunda örneklerin 0+ ile V yaş grupları arasında dağılım gösterdiği saptanmıştır. Ortalama total boy değerlerinden hesaplanan von Bertalanffy büyüme parametreleri dişi, erkek ve tüm bireyler için sırasıyla; L?=53.49 cm, 47.49 cm ve 53.90 cm; k=0.385, 0.349 ve 0.377 yıl-1; t0=-0.078, -0.112 ve -0.045 yıl; gelişim performansı indeksi (?) değerleri ise 2.895, 3.042 ve 3.040 olarak bulunmuştur
