Our Mission

The Hong Kong Marine Ecological Association (HKMEA) is a non-profit organisation dedicated to restoring our marine environment to a biologically diverse and sustainable state for all to enjoy. 

Oysters Save Our Seas (Oyster SOS) is our flagship project to restore oyster reefs in Hong Kong.

Why Oysters?

 Improve Water Quality 

 Oysters are filter feeders and an adult oyster can filter as much as 200L waters a day! 

Our Work


Informed, guided, and monitored by scientific research.
