Abstract

In this study, 547 Trachurus trachurus specimens were examined. Of these 319 (58.31%) were female and 228 (41.68%) were male. The sex ratio (female/male) was calculated as 1:1.39 and was found to be significantly different between males and females (P<0.05). The minimum and maximum lengths of the sampled individuals were calculated as 8.5 cm and 16.0 cm, respectively. Furthermore, the length−weight relationship for all individuals was determined to be W=0.01L2.9385, and the corresponding regression coefficient was found to be R2=0.8897. Regression coefficient (R2) value in the length−length relationship equation ranged from 0.88 to 0.93, with the highest (R2 ═0.93 observed in females; TL/FL) and the lowest (R2 ═0.83) recorded in males; TL/SL). These findings are expected to the conservation and sustainable management of fish stocks in the field of fisheries biology in the region.

Abstract

Bu çalışmada, 319 (58.31%) dişi ve 228 (41.68%) erkek olmak üzere toplam 547 Trachurus trachurus örneği incelenmiştir. Cinsiyet oranı (dişi/erkek) 1:1.39 olarak hesaplanmıştır. Dişiler ile erkekler arasında farkın anlamlı olduğu belirlenmiştir (P<0.05). Örneklenen bireylerin minimum ve maksimum boyları 8.5 ve 16.0 cm olarak hesaplanmıştır. Ayrıca tüm bireylerin boy-ağırlık ilişkisi ve regresyon katsayısı W=0.01L2.9385 R2=0.8897olarak hesaplanmıştır. Boy-boy ilişkisi denkleminde regresyon katsayısının (R2) 0.88 ile 0.93 arasında değiştiği belirlenmiştir. En yüksek değer 0.93 (dişilerde; TL/FL), en düşük değer ise 0.83 (erkeklerde; TL/SL) olarak hesaplanmıştır. Çalışma bulguları balıkçılık biyolojisi ve yönetimi için önem taşıyacağı tahmin edilmektedir.
