Saros Körfezi’ndeki (Kuzey Ege Denizi, Türkiye) Kupes Balığının (Boops boops Linnaeus, 1758) Üreme Zamanı ve Ağırlık-Boy İlişkisinin Belirlenmesi

Bu çalışma Ocak 2014-Aralık 2015 tarihleri arasında SarosKörfezi’nde yürütülmüştür. Türün üreme zamanı gonadların aylıkağırlık değişimleri dikkate alınarak GSI (Gonadosomatik indeks) =(Gonad Ağırlığı / Vücut ağırlığı - Gonad Ağırlığı) × 100 eşitliğinden,ağırlık-boy ilişkisi ise W = aLb denklemi kullanılmak suretiyle eldeedilmiştir. Üreme zamanının Mart ve Mayıs ayları arasında olduğugözlemlenmiştir. Dişi bireyler için ağırlık-boy ilişkisi W =0.0085TL3.11, erkek bireyler için W = 0.0095TL3.07 olarakhesaplanmıştır.

Weight-Length Relationship and Reproduction of Bogue (Boops boops Linnaeus, 1758) in Saros Bay (Northern Aegean Sea, Turkey)

This study was conducted between January 2014 and December 2015 in Saros Bay. The spawning period was estimated by monthly analyses, the changes of the gonad somatic index (GSI) using the equation: GSI = (Gonad Weight / Total Weight - Gonad Weight) × 100. The weight - length relationship was calculated using the equation W = aLb. It was observed that spawning period occurred between March and May. The weight-length relationship was calculated as W = 0.0085TL3.11 for females, W = 0.0095TL3.07 for males.
