Abstract

The present study aims to investigate the relationship between otolith length and total length for flounder (Pleuronectes flesus luscus Pallas, 1811) collected from the Eastern Black Sea coast of Turkey. 315 females and 275 males, totally 590 flounder were examined during the study. The ages of the 590 flounders ranged between I-VI years. The calculated otolith-total length relationships for females, males and combined sexes were as follows, respectively:

y= 7.472 + 4.0186 x (r= 0.7528), y= 9.308 + 2.816 x (f= 0.6854), y= 0.5376 – 5.3923 x (r= 0.8787)

The relationship between otolith length and total length was significantly different between females and males (P<0.01).
