The Chemical composition of little known marine gastropod Hemifusus pugilinus belonging to the family Volemidae was investigated. The protein, carbohydrate, fat, water content, percentage of shell weight and Trace metals like Fe, Cu, Mn, and Zn of oven dried tissues were estimated, for various length groups of males and females. The percentage shell weight varied from 61 to 68.5 in males and 59.4 to 69.7 in females. The percentage meat weight has the range of 20.9 to 24.3 and 19.7 to 25 in males and females respectively. The percentage water content accounted for 41.4 to 66.6 in males and 52.3 to 61.1 in females. The protein was found to be more than 33.1 to 55.9% in males and 33.8 to 49.78% in females. The range of carbohydrate and fat in males and females are 4.7 to 12.1 and 15-23.6% and 3.2 to 9.5 and 17 to 21.8% respectively. The trace metals level of males in the order of Fe, Cu, Zn and Mn is 521-687 41-61, 74-103, and 33-48,µgm/gm and that of females is 409-542 32-54, 109-113, and 27-36/µgm/gm dry tissue.
