The population of the green mussel Perna viridis at Paradise Point remained stable most of the year with recruitment in July and November. Allometric studies demonstrated that relationship between length and width of shell changed with the season; in some months length increased isometrically with the width and in others the shell length increased faster than width. Increase in shell length was faster than shell weight in all seasons. Shell length increased faster than shell height. A clear seasonal trend in length to dry tissue weight was observed. Dry tissue weight increased isometrically with length in one half of the year but showed negative allometry in the other part.
