This study aimed to investigate otolith in Rachycentron canadum in the Persian Gulf and Oman Sea. Sampling lasted from March ۲۰۱۴ to April ۲۰۱۵ in Khouzestan to Sistan and Baloochestan waters. During this period ۳۰ specimens of R. canadum were caught and studied. Trawling time was ۲-۲½ hours and trawling depth was considered as ۱۰-۱۰۰ m daily. All the fish were identified and their otolith was extracted for verification. Investigation of otolith morphometric characteristics (length, breadth, weight, perimeter and area) were conducted. Otolith in R. canadum was small, with average stretch and low thickness. We conclude that the otolith appearance and morphometry can be used as a key to identify the species.
