Oysters Return: Belfast Lough Sees Native Species Restored

Native European oysters have been reintroduced into Belfast Lough, marking a significant milestone in restoring a species absent for over a century. Ulster Wildlife led the effort, releasing 2,000 adult and over 30,000 juvenile oysters, cultivated in protected nurseries. This initiative aims to rebuild vital underwater reefs, essential for the species' recovery and broader marine ecosystem health.

The disappearance of European oysters from Belfast Lough was attributed to overfishing, pollution, and habitat loss. However, the recent discovery of a small surviving population spurred Ulster Wildlife's restoration plans. Support from various organizations and funding through the Carrier Bag Levy are enabling the scaling up of wild populations, with oysters delivered from Scotland and deployed by staff and volunteers.
