Memorandum of Understanding creates a partnership to support restoration of European oyster populations. Researchers are to guide the development of disease-resistant oyster strains that are suited to farming environments and can support the restoration of wild populations.Scientists at the Roslin Institute have signed a Memorandum of Understanding with industry partners The Oyster Restoration Company, Native Aqua and Xelect. This partnership aims to combat the impact of a lethal parasite that has severely hindered the recovery of European native flat oysters from a period of overharvesting, pollution and disease. Managing the parasite, named Bonamia ostreae, will help support wild populations of the oysters, of which fewer than 5 per cent remain in Europe compared with historic levels. Through this collaboration, researchers will work to identify genes or groups of genes linked to Bonamia resistance in oysters, using field trials and laboratory tests.By bridging fundamental research and practical applications, the research team hopes to help develop disease-resistant strains for restoration and aquaculture environments.Collaborative rolesThe Roslin Institute team will identify genetic traits linked to disease resistance, while providing scientific expertise to support the breeding processes carried out by industry partners.The Oyster Restoration Company will focus on breeding and supplying oysters, while technical genetics company Xelect will apply advanced genetic screening to identify markers linked to disease resistance.Native Aqua will assist with early-stage sustainable oyster farming and provide practical insights into the growth and survival of oysters for both food production and restorationTailored solutionsBy understanding and managing oyster genetics, the team aims to help produce oysters that meet the diverse needs of several stakeholders. While oyster restoration projects require resilient, disease-resistant populations, the food industry benefits from fast-growing, uniform oysters.Research is anticipated to begin in January 2025, subject to funding. This partnership brings together a unique blend of expertise to tackle one of the biggest challenges facing native oysters. By understanding the genetic traits that make oysters more resistant to Bonamia, we hope to develop robust oyster populations that can survive in both infected waters and commercial farms. This initiative reflects a long-term commitment to oyster restoration and aquaculture, aiming to safeguard the future of this aquatic species.
