Abstract Otolith morphometrics, coupled with image analysis and mathematical equations were examined to investigate stock structure of Anchovy, Encrasicholina punctifer on Persian Gulf and Oman Sea. Samples (360 Otolith) were collected during December and January 2012 from three main fisheries landing including Gheshm, Garze and Jask. The structure of transverse sagittal otolith sections were described for individual anchovy samples by using Image motic software. The measured parameters for each otolith were: length, width, weight, perimeter and area. In addition, the morphological indices of otoliths including roundness, oval and circular indices were measured by mathematical equations. Results from this study showed a similarity in morphological and morphometric parameters of Otoliths of anchovy stocks collected from Gheshm, Garze and Jask. Therefore, theses three populations could be considered as single population.
