Biodiversity and Oyster Reefs of Hong Kong

There is currently no ecological or biological base li ne for oyster habitats in Hong Kong. These habitats are globally recognised to be biologically diverse and highly productive. Despite the long history of exploitation of oyster habitats in Hong Kong, with written records pre dating the Qing Dynasty (c.1630s), there is no information on their current status or the diversity of species which rely on them.

Overall, this project will establish the first comprehensive dataset for fauna associated with these remnant oyster habitats and provide a base line from which to manage them into the future.

There is an urgent need to document baseline ecological conditions of oyster habitats while the natural ecosystem still exists from both scientific and socio-cultural perspectives, as well as to inform any potential future restorative conservation.

Project Objectives

1. Database of faunal biodiversity associated with oyster habitats and soft sediment shores including a reference collection of all key invertebrate species







New species record for Hong Kong, Nanosesarma pontianacense , found
inhabiting the pilot restoration reef at Lau Fau Shan. 

2. DNA barcode for all the marine species and to create a DNA reference collection

3. Update the Hong Kong Register of Marine Species (HKRMS), founded by SWIMS and
funded by ECF and the HK node of the World Register of Marine Species (WoRMS)

4. Document the abundance and distribution of threatened or endangered species  in habitat adjacent to oyster habitats
