The otolith lengths, widths and weights (minimum-maximum ±standard deviation) were determined as 2.56-3.76 ±0.22 mm, 1.66-2.56 ±0.18 mm and 5.2-12.5 ±1.27 mg, respectively. Total lengths of the fishes were found as 377-699 ±53.5 mm. In addition, a high positive linear correlation was detected between the otolith size and total length of fishes.
