Rapid urban expansion and lax zoning enable commercial fish farms to occupy protected wetlands in Hong Kong, exposing governance gaps and ecological risk

Peer‑reviewed studies show that intensive fish ponds near Ramsar sites increase nutrient loading, leading to eutrophication and loss of bird foraging habitats. Hydrological modelling indicates that runoff from the ponds can alter salinity gradients crucial for mangrove seedlings. Scientific evidence thus underscores the ecological stakes of unregulated aquaculture adjacent to protected wetlands.
The encroachment of commercial fish farms onto Hong Kong's protected wetlands is not an isolated regulatory lapse but a symptom of a development model that privileges short‑term economic gains over long‑term ecological health.
Historical patterns of land reclamation, coupled with rising land values and a governance structure that marginalises Indigenous and community voices, have created a fertile ground for ecological disruption. By integrating Indigenous stewardship, scientific modelling, and cross‑cultural best practices into a robust ICZM framework, Hong Kong can reconcile aquaculture productivity with wetland preservation. Leveraging green technologies like recirculating aquaculture systems and incentivising ecosystem services can align market forces with conservation goals, while a regional knowledge hub ensures that lessons from other Asian coasts inform local policy. Together, these pathways reconfigure power relations, embed systemic resilience, and safeguard the migratory bird habitats that define the region's natural heritage.
