This study aimed to investigation of otolith in some species of Ariidae family in Persian Gulf and Oman Sea. Sampling lasted from September 2011 to December 2012. During this period two species (Arius dussumieri and Arius thalassinus) were cut and studied. Trawling time was 2-2½ hours and trawling depth was considered as 10-100 m daily. Catching and sampling operations was done within 24 hours. Sampling and catching was done in Khuzestan and Bushehr waters in fall and winter of 2011and since the third week of September 2012 sampling was done in Hormozgan and Sistan and Baloochestan waters. All the fish were identified and their otolith was extracted to verify them. Investigation of otolith morphometric characteristics (length, breadth, weight, perimeter and area) was conducted.
