Length-weight relationships of five Symphodus species (Pisces: perciformes) from İzmir Bay, Aegean Sea

Bu çalışmada, İzmir Körfezi (Ege Denizi)’nden beş Symphodus türünün (Symphodus cinereus, Symphodus mediterraneus, Symphodus ocellatus, Symphodus rostratus, Symphodus tinca) boy-ağırlık ilişkileri sunulmuştur. Örnekler, Ocak 2005-Mayıs 2006 tarihleri arasında dip trolü ile 15-20 m derinlikten yakalanmıştır. Eğim değerleri -b- 2.907 ile 3.292 arasında değişmiştir. S. cinereus, S. ocellatus ve S. rostratus türleri için pozitif allometrik büyüme gözlenirken, S. mediterraneus ve S. tinca türlerinde izometrik büyümenin olduğu belirlenmiştir.

İzmir Körfezi (Ege Denizi)’nden beş Symphodus türünün boy-ağırlık ilişkileri

In this study, length-weight relationships are presented for five Symphodus species (Symphodus cinereus, Symphodus mediterraneus, Symphodus ocellatus, Symphodus rostratus, Symphodus tinca) from İzmir Bay, Aegean Sea. Samples were caught in depths of 15-20 m by bottom trawls between January 2005 and May 2006. The value of the slope ,-b-, ranged between 2.907 and 3.292. Isometric growth was determined for S. mediterraneus and S. tinca, while positive allometry was observed for S. cinereus, S. ocellatus and S. rostratus.
