Biometry of Iranocichla hormuzensis was compared between males and females and two seasons. A total of 120 specimens were collected from Mehran River and 25 morphometric and 13 meristic characters were measured. All mean values of the morphometric characters, except eye diameter and pectoral fin base length, were significantly higher in males (p<0.05). To analyze the effects of seasonal change on biometric characters, these characters were compared in wet and cooler (October-March) and dry and warmer (April-September) seasons for males and females. All morphometric characters increased significantly (p<0.05) from wet to dry season, although females were more affected by season than males. The correlation between morphometric measurements and total length, except for the pectoral fin base length, were high. There were no significant differences in meristic characters between males and females of I. hormuzensis. Comparison between meristic characters in different seasons showed that rudimentary caudal fin rays and scales above the lateral line in dry season were significantly higher than in wet season for both sexes (p<0.05). Sex and season did not significantly affect the meristics of the Iranian cichlid, however, morphometrics were highly affected by these factors and should be considered in comparative biology studies.
