| The morphology, biometry and shape indices of the left and right sagittal otoliths were studied for sharpsnout seabream, Diplodus puntazzo species from Aegean Sea. The shape, sulcus acusticus shape, proximal and distal surfaces, anterior and posterior regions of left and right sagittal otoliths for a total of 52 D. puntazzo were analyzed. The morphometric measurements such as weight, length, width, area and perimeter were recorded for each pair of sagittal otoliths of the sharpsnout seabream. The shape indices such as form factor, roundness, aspect ratio, circularity, rectangularity, and ellipticity were calculated for left and right sagittal otoliths of D. puntazzo. The otolith width and ellipticity were significantly different (P <0.05) for left and... |

| The otolith morphology, biometry and the relationship between the otolith size and fish length were examined. The weight, length, width, area and perimeter were recorded for each pair of otoliths. The values of form factor (FF), roundness (RD), aspect ratio (AR), circularity (C), rectangularity (R) and elipticity (E) were calculated and the relationships between otolith length (OL) and shape indices were showed with graphics. According to paired t-test results, difference between right and left otoliths was important statistically (P<0.05), except otolith length. It is the first time, the difference of otolith variables were observed not only right and left pairs but also females and males of fish a member of Cyprinidae. While the otolith weight had the... |
