Oyster Culture at Lau Fau Shan

Oyster Culture

Culture of oyster has been practised along the intertidal mud flat of Deep Bay in northwestern corner of Hong Kong for at least 200 years.

Traditionally, oysters are cultured by the bottom culture method with spat collected by laying rock, concrete tile or post as cultch on the mud flat in May or June. The oyster spat takes four to five years to grow to marketable size. In recent years, some farmers turned to fattening of medium size oysters imported from the Mainland. Majority of them adopt the raft culture method, i.e. oysters placed in baskets suspended from rafts.

These oysters generally take about six to twelve months before marketing.
