Abstract

Growth parameters and gonadosomatic index (GSI) (%) of 459 horse mackerel Trachurus trachurus (L. 1758) were studied in Dardanelles between September 2001 and August 2002. The age composition of the sampled population varied between 0 and 3, where the 0-age group contained the highest number of fish (59.0%). The population was composed of 57% females and 43% males, respectively. The total length varied from 8.80 to 25.90 cm and the body weight varied from 8.50 to 171.72 g. The Von Bertalanffy equation was estimated as Lt = 30,34 $(1 -^{e-0255 (t+2.481)})$ for both sexes combined. Maximum monthly mean of the GSI for males (3.77%) and females (3.91%) were observed in April 2003.

Özet

Bu çalışmada, Eylül 2001 ve Ağustos 2002 tarihleri arasında Çanakkale Boğazı'nda yakalanan 459 adet karagöz istavrit balığının büyüme parametreleri, gonadosomatik indeks değeri ve et verimi incelenmiştir. İncelenen bireylerin yaş kompozisyonu 0 ile 3 yaş arasında değişim göstermekte olup, en fazla bireye 0 yaş grubunda rastlanmıştır. Populasyonun % 57'si dişi, % 43'ü ise erkek bireylerden oluşmuş, balıkların boyları 8,80 cm ile 25,90 cm arasında, ağırlıkları ise 8,50 gr ile 171,72 gr arasında değişim göstermiştir. Bütün bireyler için VonBertalanffy denklemi Lt = 30,34 $(1 -^{e-0255 (t+2.481)})$ olarak hesaplanmıştır. En yüksek GSI değeri hem dişi (% 3,91) hem de erkek (% 3,77) bireyler için Nisan ayında gözlenmiştir.
