Reviving Hong Kong's Ocean Heritage – Our Forgotten Oyster Reefs (Cityplaza)

Globally an estimated 85% of oyster reefs have vanished due to coastal development pollution overharvesting and climate change. In Hong Kong only about 6% of Hong Kong’s marine waters are protected leaving critical ecosystems such as oyster reefs vulnerable to further degradation. Oysters are natural “ecosystem engineers”. At summer one single adult local oyster can filter up to 960 liters of water a day — even more for Hong Kong oyster! This improves water quality and supports diverse marine life. Oyster reefs provide shelter for a wide range of marine species and act as natural buffers against coastal erosion. This alarming decline threatens not only marine biodiversity but the health and resilience of our entire ocean system.

The exhibition offers an engaging multisensory learning experience designed to educate and inspire visitors of all ages. Through engaging visual displays interactive installations and captivating narratives visitors can explore the ecological importance of oyster reefs.
