It was found that there is a strong correlations between otolith length-total length (r2 =0.88) and otolith width-total length (r2 0.81).
📌 3 Key Takeaways

📊
Key Findings & Data:The relationship between total length and otolith size of 346 bluefish samples were examined.
💡
Conclusion & Impact:It was found that there is a strong correlations between otolith length-total length (r2 =0.88) and otolith width-total length (r2 0.81).
In the present study, bluefish, Pomatomus saltatrix, was monthly collected from commercial fishing boats operating in the Marmara Sea between January and December 2014. The relationship between total length and otolith size of 346 bluefish samples were examined. Total lengths of females, males and unidentified samples were ranged from between 13.2-37.0, 12.3-34.8 and 13.0-31.6 cm, respectively. Otolith lengths were between 3.82-12.60 mm and otolith width were between 1.59-4.34 mm for all samples. It was found that there is a strong correlations between otolith length-total length (r2 =0.88) and otolith width-total length (r2 0.81).
