One health

Disease & stress tolerant strains

Cultivation of Hong Kong (HK) oyster species in southern China contributes to a quarter of global edible oyster production. HK oysters are Omega−3 rich nutritious delicacy, mainly consumed by rising middle-class populations. Hence, sustained expansion of this sector is essential for seafood security. However, this sector faces unprecedented challenges due to reclamation of their estuarine habitats and climate change — these human impacts are not only directly deteriorating oyster food safety and security but also seriously affecting wild seed production. The collected few wild seeds also experience mass mortality during the harvesting period in winter and their performance is often unpredictable. Thus, the sustainable aquaculture in the region is now heavily depending on hatchery produced seeds from stress tolerant and disease resilient population, especially their triploid version; and on how quickly we adapt the one health approach in aquaculture. As part of this effort, the HK-SAR has funded HKU to establish a research-based hatchery for developing novel technology to modernize the sector with knowledge exchange — the project is running smoothly in collaboration with growers and Lee Kum Kee Ltd. This 2nd “world is our oysters (WOO)” symposium is called: 

  • To demonstrate the newly designed oyster hatchery, and explain its operational protocol to various stakeholders; 

  • To identify ways through which new oyster hatchery technologies could be integrated with national effort to develop sustainable oyster aquaculture for one health with global perspective; and 

  • To discuss about the need, objectives and deliverables of the emerging “Oyster Aquaculture Alliance for One Health (OAA@HKU)”.
