This study was therefore conducted to determine the possible sexual dimorphism between male and female Glossogobius celebius; and to classify them from other Goby species to formulate proper management programs in fisheries. 78 samples (male=37, female=41) collected from the stressed regions of the lake were processed using Geometric Morphometric techniques. Digital Images of the species were captured using Canon 1100 D and were further elucidated using landmark based Geometric Morphometrics. Relative Warp Analysis show males with leaner bodies and lengthier caudal peduncle and gape length. In contrast, females exhibit corpulent body outlines and curvatures in greater degrees. MANOVA unveiled that male and female species were significantly dimorphic: Wilk&rsquo;s lambda = 0.3358, Pillai trace = 0.6642 and p=4.648E-15. Thus, male and female G. celebius are significantly dimorphic due to sexual roles during reproduction for their better mating opportunities.</span></em></strong></span></p>
