chi, 1966) by the application of anti-fouling paints. Undoubtedly the main disadvantage to this technique is that a large capital investment is required with high maintenance costs and a greater chance of damage and loss during a typhoon. As noted earlier oyster culture in Deep Bay is at present being run on a family basis lacking a large capital investment. The adoption of the more expensive raft method of culture would appear, under present socio-economic conditions, to be impossible. The setting up of a co-operative system by the oyster farmers concerned, together with an extension of the Government loan scheme for fisheries development to the oyster industry could enable the oyster farmers to obtain the necessary finance to improve the industry. With an available source of funds for investment and with further detailed research to determine the modifications required to ensure the success of a programme of modernisation in the special environment of Deep Bay, Hong Kong's oyster industry is not without a future.
