In the present study, an otoscope was used to sex identification of 3-year old great sturgeon Huso huso in a weight range of 2.5-5.5 kg. For direct observation of gonads and identify sexes, 2350 fish were considered for this procedure with a small incision of 0.6-0.8 cm through the abdomen with insert of otoscope into the body cavity. The results showed that 99.2% of fish could be sexed via the otoscope and the sex ratio was classified as 1:0.98. Result revealed that otoscopy is a high accurate and efficient technique for sex identification of great sturgeon in 3-year old fish.
