PRIMARY PRODUCTION
Vietnam does not encourage the use of these grounds. Some of the deep-sea vessels still depend on sail and their activities are severely curtailed during the typhoon season from June to October. The restrictions imposed by the Chinese People's Government in 1958, requiring fishermen based on Hong Kong who sail in Chinese inshore waters to land a quota of their catch in China, are still in force. Landings by the local fishing fleet in 1966 were generally good and wholesale prices also improved. The activities of the fleet were, however, affected by a general shortage of crew as a result of an increasing number of fishermen seeking employment on shore.
Oyster Farming. Edible oysters have been cultivated in the waters of the Colony for some 700 years. The principal area of cultivation is Deep Bay where 222 long tons of oyster meat, valued at approxi- mately $1,235,500, were produced from 6,060 acres along the New Territories' shores of the bay. Some of this was processed into dried meat or oyster juice and exported to markets overseas. A small research station which has been constructed at Kat O in Mirs Bay has commenced investigations into the possibility of introducing into Hong Kong waters more exotic species of oysters from temperate regions. An infant pearl culture industry is being established in the Tolo Channel, Double Haven and Port Shelter
areas.
FISH MARKETING ORGANIZATION
The present Fish Marketing Organization grew out of the steps taken to rehabilitate the fishing fleet at the end of the Pacific War. Interest-free loans and grants were made and a fish marketing scheme was introduced with the long-term object of developing the industry on a sound economic footing. From this beginning devel- oped the present non-government trading organization controlled by a civil servant, now the Director of Agriculture and Fisheries. The organization is a non-profit-making concern which finds its revenue and pays its expenses from a 6 per cent commission on all the sales in its wholesale markets. It operates under the Marine Fish (Marketing) Ordinance 1956, which provides among other things for a Fish Marketing Advisory Board composed of unofficials to assist the organization.
The organization runs five wholesale fish markets at Aberdeen and Shau Kei Wan on Hong Kong Island, Cheung Sha Wan in
