Abstract :In the present study, the relationships between sagittal otoliths insert ignore into journalissuearticles values(otolith length insert ignore into journalissuearticles values(OL);, height insert ignore into journalissuearticles values(OH); and weight insert ignore into journalissuearticles values(OW););, fish size insert ignore into journalissuearticles values(fish length insert ignore into journalissuearticles values(TL); and weight insert ignore into journalissuearticles values(W);); in brown comber insert ignore into journalissuearticles values(Serranus hepatus, Linnaeus, 1758); were analysed. Fish specimens insert ignore into journalissuearticles values(N=504, 41–133 mm in TL and 1.05–31.98 g); were captured by bottom trawl vessels from off the Güllük Bay insert ignore into journalissuearticles values(Southern Aegean Sea); between January and December 2013. Left otolith pairs were used for calculations since there was no statistical differences between left and right otoliths insert ignore into journalissuearticles values(P>0.05);. Regression formulas were used as follows: TL= 16.94*OL+10.14, TL= 26.77*OH+24.88, TL= 375.7*OW0.315, W= 0.251*OL2.431, W= 2.009*OH1.917, W= 854.0*OW+1.552, OH= 0.600*OL–0.394, OW= 0.00025*OL2.555 and OW= 0.001*OH2.007. Calculated regressions were revealed a high coefficient of determinations ranging from 0.865 to 0.960. It is found that otolith sizes and weight are good indicators of the total length and weight of S. hepatus.
