Purification of farm grown oysters

The purification of farm grown oysters by scientific methods is essential before they are marketed. Oyster farming is a new venture in India and the technique has recently been perfected by the Central Marine Fisheries Research Institute. The most important task is to perfect the depuration process for which there is no standard method. The present paper gives a satisfactory plan for small scale purification of harvested oysters before they are marketed for safe human consumption.
