Abstract
The present study aimed to confirm the existence of relationships between the otolith size (otolith length, otolith breadht, otolith area, and otolith weight) and the size of Sander. lucioperca (L., 1758) from Eğirdir and Beyşehir Lake, Turkey. The length-weight relationships were defined as W = 0.0030L3.386 (R2 = 0.993) for females, W = 0.0032L3.309 (R2 = 0.987) for males from the Eğirdir Lake, and W = 0.0033L3.339 (R2 = 0.977) for females, W = 0.0024L3.410 (R2 = 0.976) for males from the Beyşehir Lake. No significant relations total length and otolith length (OL), otolith breadth (OB), area (A), and otolith weight (OW) were found both the sexes and all the localities. The maximum coefficient of determination were observed between total length and OL, A and OW, while the minimum was observed for OB. The results showed that can be used for the monitoring of stocks in pikeperch populations benefit otolith size.
