53. Mr. Rostron Duckworthasked the Minister of Agriculture what progress has been made during recent years in the commercial production of oysters in tanks on the coasts 'of Great Britain; and whether research has yet reached a point where this industry can be expanded on a large scale?
§ Mr. W. S. MorrisonThere has been no production of oysters in tanks on a commercial scale up to the present in Great Britain. Experiments have, however, been undertaken in oyster-breeding in tanks since 1919, and for some years systematic and co-ordinated research in the matter has been in progress. A stage has now been reached in the evolution of a tank-breeding process when it is thought that commercial success in this method of production may be anticipated with some confidence.
