Proximate composition of the surf clam Mactra violacea (Gmelin 1791)

The surf clam Mactra violacea (Bivalvia: Mactridae) is a fairly large marine clam with high meat content. These clams are found in the surf zone of exposed sandy beaches. The proximate composition of M. violacea was studied. Moisture, crude protein, crude fat, acid insolubles and ash were estimated. The protein content of M. violacea was estimated as 11.9 %, fat 1 %, ash 3.2 % and moisture 80 %. The surf clam is a good source of protein and minerals and has low fat content. The nutritive value is high and comparable to other shellfishes
