Abstract
    In contrast to many Crustacea, marine bivalves swallow their food whole. This means that the wall of the microcapsule must be broken down in the gut, either by digestive enzymes or by a change in pH. Some preliminary experiments are described on the ingestion of microcapsules of various size ranges by Mytilus edulis, and the digestion of the capsule wall by the stomach juice of Crassostrea gigas. This includes experiments with nylon-protein capsules and with capsules containing a carbohydrate-protein complex in the wall and experiments on the growth of C. gigas spat on a simple micro-encapsulated diet.
