The Persian Gulf and Oman sea fish have valuable economic species. The purpose of this study was to evaluate morphometric properties and otolith biometry of Tigertooth croaker Otholites rober in Persian Gulf and Oman sea. The otolith of 20 fish was extracted from their abdominal sections after biometry, and the otolith indices were calculated. The results of four morphometric and six meristic measurements were recorded as: body weight (394±12.7), total length (34.25±2.1), standard length (30.25±1.4), body depth (8±2.7), number of vertebrae of the spine (23-24), scales type (catenoid), number of hard rays of dorsal (27-28), anal (8), thoracic (12-14) and abdominal fins (5). The otoliths showed a sharp rostrum, blade post-rostrum, and a certain anti-rostrum. The otolith indices of size (0.035), elongation (1.89) and thickness (0.34) showed the average range and closer in shape to an oval. The linear regression showed positive correlations between the otolith length and width, the otolith length and width with weight of the fish, and between the fish length and the otolith length (p <0.05), but no significant correlation was found between otolith weight and fish weight (p >0.05).
