Özet:

 


Fish otoliths
are generally used to determine taxon, age and size of the teleost fishes and
are useful tools for studies of prey-predator relationships, population
dynamics and ichthyo-archaeology. In the present study, the equations for the
relationships were calculated between fish length (TL), weight (W) versus
sagittal otolith length (OL), height (OH) and weight (OW) in comber (Serranus cabrilla, Linnaeus, 1758)
specimens (N=310, 95–225 mm in TL and 7.54–111.27 g) captured via bottom trawl
vessels from off the Güllük Bay (Southern Aegean Sea) between January and
December 2013. Since there has been no statistical differences between left and
right otoliths (p>0.05), left otoliths were used for calculations.
Regression formulas were calculated as follows: TL=28.75*OL–22.31,
TL=64.36*OH–6.808, TL=2380*OW0.640, W=0.056*OL3.618, W=2.029*OH3.254,
W=5168*OW–28.33, OH=0.414*OL–0.054, OW=0.0000053*OL1.542, and OW=0.003*OH1.382.
The aim of this study is to fill in the missing data concerning otolith and
fish size relationships of the species in the southern Aegean Sea, thereby
providing researchers studying food habits of top predators to determine the
size and weight of prey fish from length or weight of recovered otoliths.
