A preliminary study on some morphologic characteristics of Trachurus trachurus (Linnaeus, 1758) and Trachurus mediterraneus (Steindachner, 1868) populations in the Aegean, the Marmara and the Black Sea

Some morphological characteristics of T. mediterraneus and T. trachurus in the Aegean, the Marmara and the Black Sea were investigated. The samplings were carried out between June 2000 and January 2001. The fork length versus body weight relationships were obtained from the allometric model; fork length–head length, fork length–predorsal, head length–preorbital,
head length–eye diameter relationships were also obtained from the log-linear model. Generally, all the regressions were highly significant (p<0.05) as is usual between body proportions.

Ege, Marmara ve Karadeniz’de, T. mediterraneus ve T. trachurus’un bazı morfolojik özellikleri araştırılmıştır. Örneklemeler, Haziran 2000 ve Ocak 2001 tarihleri arasında yürütülmüştür. Çatal boy–ağırlık ilişkisi allometrik modelden elde edilmiştir. Çatal boy–baş boyu, çatal boy–predorsal, baş boyu–preorbital, baş boyu–göz çapı ilişkileri de log-linear modelden elde edilmiştir. Genel olarak, bütün regresyonlar, vücut oranları arasında beklendiği gibi önemli (p<0.05) bulunmuştur.
