Bu çalışmada Türkiye’nin Ege Denizi ve Akdeniz kıyılarından yakalanmış ekonomik değeri yüksek bir tür olan Boops boops’ta otolit kütle asimetrisi (X) ve mutlak otolit kütle asimetrilerinin (IXI) belirlenerek, lokasyonlar arasında karşılaştırma yapılması amaçlanmıştır. Her iki lokasyonda da sağ-sol otolit çiftleri arasında istatistiksel açıdan herhangi bir fark çıkmamıştır (P˃0.05). Ortalama otolit kütle asimetrisi ve mutlak kütle asimetrisi değerleri sırasıyla Ege Denizi ve Akdeniz'e göre -0,00078±0,00405 ve 0,0021±0.00258 ile -0,00606±0,0049 ve 0,0015±0,00401 olarak bulunmuştur. Ayrıca, otolit kütle asimetrisi lokaliteler arasında anlamlı farklılık göstermezken (P˃0,05), mutlak otolit kütle asimetrisi lokaliteler arasında farklılık göstermiştir. Ayrıca hem X hem de IXI- balık boyu ilişkileri linear regresyon denklemi kullanılarak belirlenmiştir. Gerçekleştirilen analizler, balık boyu ile X arasında her iki lokasyonda da bir ilişki olmadığını ortaya çıkarmıştır (P˃0.05). ancak balık boyu- mutlak otolit kütle asimetrisi ilişkileri incelendiğinde Akdeniz lokasyonu için önemli bir ilişki belirlenmezken (P˃0.05), Ege Denizi’nde balık boyu- mutlak otolit kütle asimetrisi ilişkisi önemli bulunmuştur (P<0.05). Bu çalışmanın sonuçları, Türkiye'de Ege Denizi ve Akdeniz'den örneklenen B. boops için balıkçılık yönetimi önlemlerinin ve koruma stratejilerinin geliştirilmesine yardımcı olabilecek önemli bilgiler sunmaktadır.

This study aimed to determine otolith mass asymmetry (X) and absolute otolith mass asymmetry (IXI) in Boops boops, a species of high economic value sampled from the Aegean Sea and Mediterranean Sea in Türkiye, and to make comparisons between locations. No statistically significant difference was found between right-left otolith pairs in both locations (P˃0.05). The mean otolith mass asymmetry and absolute mass asymmetry values were found to be -0.00078±0.00405 and 0.0021±0.00258, and -0.00606±0.0049 and 0.0015±0.00401 for the Aegean Sea and the Mediterranean Sea, respectively. In addition, otolith mass asymmetry did not show significant differences among localities (P˃0.05), while absolute otolith mass asymmetry differed between localities. Also, the relationships between X-IXI and fish length were determined using a linear regression equation. The analyses revealed no relationship between fish length and X in either location (P˃0.05). However, when examining the relationships between fish length and absolute otolith mass asymmetry, no significant relationship was found for the Mediterranean location (P˃0.05), while the relationship between fish length and absolute otolith mass asymmetry was found to be significant in the Aegean Sea (P<0.05). The results of this study provide important information that can aid in the development of fisheries management measures and conservation strategies for B. boops sampled from the Aegean Sea and the Mediterranean Sea in Türkiye.
