Özet:

 The small-sized adult and juvenile fish species have great ecological importance by means of the prey-predator relationship. Due to these species become prey of larger fish species, their otoliths are mostly seen in the stomach content of predators. The fish size-otolith size studies reveals robust data for estimating fish size from the otolith size. To contribute this aspect, the relationships between total length and otolith length TL-OL, total length and otolith width TL-OW, total length and otolith radius TL-OR of seven species Liza sa-liens, Pomatoschistus marmoratus, Pomatoschistus bathi, Pomatoschistus minutus, Synapturichthys kleinii, Chelidonichthys lucerna and Symphodus roissali were investigated. Species were obtained by beach-seine nets from 12 sampling stations in the shallow waters of the Marmara Sea. While calculating the relationships, linear regression analysis y  bx  a was used and the coefficient of determination R2 was identified. The R2 values were usually seen as high in all equations. The highest values of R2 for TL-OL and TL-OW were obtained from P. minutus, while the highest values of TL-OR detected were for C. lucerna. The lowest values of R2 for TL-OW and TL-OR were obtained from P. marmoratus, while the lowest values of TL-OL were de-tected for P. bathi. This study revealed the first results for P. minutus, S. kleinii, S. roissali in the Turkiye Seas and for P. bathi in the worldwide by means of fish length  otolith size relationships.

 Av-avcı ilişkileri açısından juvenil ve küçük boyutlu ergin türlerin ekolojik önemi büyüktür. Bu türler genellikle daha büyük boyutlu türlerin besini olduğundan, bunlara ait otolitlerde avcıların midelerinde sıklıkla görülmektedir. Balık boyu-otolit boyutu ilişkileri çalışmaları, otolit boyutundan balık boyunu tahmin etmek için güvenilir veriler ortaya koymaktadır. Bu konuya katkı sağlamak amacıyla, Marmara Denizindeki sığ sulardan, 12 farklı istasyonda ığrıp av aracı ile örneklenen yedi türün Liza saliens, Pomatoschistus marmoratus, Pomatoschistus bathi, Pomatoschistus minutus, Synapturichthys kleinii, Chelidonichthys lucerna ve Symphodus roissali, toplam boy ile otolit boyu TL-OL, toplam boy ile otolit genişliği TL-OW ve toplam boy ile otolit yarıçapı TL-OR ilişkileri belirlenmiştir. İlişkiler hesaplanırken, doğrusal regresyon analizi y  bx  a kullanılmış ve determinasyon katsayısı R2 belirlenmiştir. R2 değerlerinin tüm denklemlerde genellikle yüksek olduğu tespit edilmiştir. TL-OL ve TL-OW için en yüksek R2 değeri P. minutusta elde edilirken, TL-OR için en yüksek R2 değeri C. lucernadan elde edilmiştir. TL-OW ve TL-OR için en düşük R2 değeri P. marmoratustan elde edilirken, en düşük R2 değeri TL-OL değeri P. bathiden elde edilmiştir. Bu çalışma otolit boyutu - balık boyu ilişkisi alanında, P. bathi için dünya genelinde, P. minutus, S. kleinii, S. roissali için Türkiye Denizlerinde ilk sonuçları ortaya koymuştur.
