Abstract: This study was performed in order to identify sexual differentiation characters of Jade perch as farmers have claimed to have difficulty to identify male and female for reproduction purpose. In order to address this issue, the morphometric characters differences between female and male was studied. Gonadal histological analysis were further applied to confirm sexual identification characters. In the present study, correlations and linear regression analysis were performed for selected 29 morphometric and 11 meristic characters in relation to total length (TL) on 50 specimens. Significant sexual dimorphism between male and female (p<0.05) found in six morphometric characters differences as body depth; head depth; anal fin length; Posterior end of the Dorsal fin to Origin of the Anal fin; Origin of the Dorsal fin to Insertion of the Pelvic fin; and pre-orbital length. Morphmetrical analysis revealed that female have slightly larger body width, while the male have a bit longer anal fin and more tapered head. Gonadal histology used for confirmation the distinguish between the male and female, which elucidated different developmental stages in of testis and ovary both. Thus, our present study proved that meristic characters cannot be used to differentiate sexes. Nevertheless, morphological characters can be identified phenotypic variations between the male and female in accompanied with gonadal histology, and the shape of genital papilla.
