The relationships between sagitta otolith morphometry (length, height, and weight) and fish size (standard length and weight) were examined for ten species of clupeids in the Persian Gulf and Oman Sea. We provide new information regarding otolith morphology and body size relationships of these clupeids. Statistical tests to examine correlation between left and right otolith dimensions showed no significant differences. Regression models relating each otolith morphometric parameter to fish length are provided. According to the morphometric relationships obtained, we concluded that length and weight of otolith are good indicators for fish standard length and weight in all the sampled species.
