| contents | Valenciennes, 1830 Otolith Morphology, Age, and Growth in the Aegean Sea (E. Mediterranean). Legaki, Aglaia Leonhard, Isabella Mytilineou, Chryssi Anastasopoulou, Aikaterini Otoliths are important structures for balance and hearing of fish and constitute a useful tool in fisheries science. This study provides, for the first time in the Mediterranean, information on the otolith morphometrics of , collected from the South Aegean Sea, and enriches the existing information on its age and growth by sex. The otolith shape variables examined showed a more circular to square otolith shape, related to the body size. Significant differences between sexes were detected for the otolith , , and . Exponential regressions were used to examine the relationship of the otolith variables with total body length, from which five showed a strong correlation (, , , and ). The eviscerated weight-length relationship exhibited an isometric growth for both sexes, whereas when total weight was applied, a positive allometric growth was found for females. Sagittal otolith readings revealed four age groups for females and five for males. A Bhattacharya method was used for age validation. Von Bertalanffy growth parameters were as follows: = 23.08, = 0.27, = -1.93 for females and = 24.07, = 0.24, = -2.26 for males. This research offers valuable biological information for useful in fisheries science. |
