Perna viridis (Green Mussels) is characterized by fast-growing, found in large clusters, one of the dominant bio-fouling organisms, native to West Indo Pacific region and commonly distributed along the Southeast Indian and Asian coast. They are found in the shallow sublittoral water up to a depth of 15 m and be able to tolerate an extensive range of environmental situation i.e. tolerate temperatures range of 15-32.5C. Green mussels were collected from the navigation buoy in Manora Channel and brought to the research laboratory. Samples were washed to remove the sand, vegetation, and other particles. Morphometric measurements were measured to the nearest gram. The result revealed that the shell length ranged between 0.60-7.4 cm, the width range between 0.10-2.9 cm, and the weight range between 0.037-15.549 g. In all morphometric relationships, the validation of the “b” values was significantly different from the isometric value. Significant correlation variation was observed in all variables whereas the highest correlation values were observed in the length-width (n-224, r2 = 0.966) and the lowest was observed in width-total weight (n-224, r2 = 0.85). The analysis of variance (ANOVA) revealed that all variables showed significantly different (DF=1, p<0.000).
