Over 900 mature native oysters (Ostrea edulis) have been suspended in 30 purpose-built cages over the edges of Carrickfergus Marina’s pontoons to help revive the species.
Led by local nature conservation charity Ulster Wildlife in partnership with Mid and East Antrim Borough Council, the restoration initiative could see up to 900 million oyster larvae released into surrounding waters every year. In addition to supporting the expansion of wild populations, the oysters will help boost biodiversity and improve water quality by filtering pollutants.
Carrickfergus was once the heart of Belfast Lough’s thriving native oyster industry in the 1850s, home to the world-famous Carrick oyster. However, a combination of overfishing and disease led to their disappearance from Belfast Lough and beyond.
