Genetic science sets out to save native oysters
A joint initiative has been set up in the UK with the aim of using the latest genetic research to protect native oysters against disease.
The Roslin Institute, The Oyster Restoration Company, shellfish farmer Native Aqua, and breeding and genetics business Xelect have signed a memorandum of understanding to work together to address the dramatic decline of European native flat oysters (Ostrea edulis). This strategic alliance aims to develop disease-resistant oyster strains through advanced genetic research, tackling the devastating impact of the parasite Bonamia ostreae and its participants hope to set a new benchmark in sustainable aquaculture.
With European native oyster populations dwindling to less than 5% of their historical levels due to overharvesting, pollution, and disease, this initiative marks a crucial step forward in both ecological restoration and the future of sustainable seafood production, the consortium said.
The collaboration focuses on identifying genetic markers that confer resistance to Bonamia ostreae. By combining cutting-edge genomics with practical breeding programmes, the partnership aims to cultivate resilient oyster strains that can thrive in both wild and farmed environments.
- The Roslin Institute will lead genetic research efforts, identifying traits linked to disease resistance.
- The Oyster Restoration Company will manage breeding efforts and provide oysters for research projects.
- Xelect will utilise advanced genetic screening technologies to optimise the selection of resilient oyster strains.
- Native Aqua will apply expertise in sustainable farming practices, supporting the oysters’ adaptation across diverse habitats.
The initiative is designed to support environmental restoration, delivering robust, disease-resistant oysters to replenish wild populations and restore marine ecosystems.
It also aims to benefit the food industry, supplying fast-growing, consistent oysters tailored to meet modern market demands.
Research is set to commence in January 2025, pending final funding approvals. By bridging the gap between fundamental science and real-world applications, the partnership seeks to transform the landscape of marine conservation and aquaculture innovation.
“This collaboration represents a transformative approach to one of the most pressing challenges in marine biology,” said Dr. Tim Bean, Senior Researcher at The Roslin Institute. “By leveraging our collective expertise, we are not only advancing scientific understanding but also creating tangible solutions for the sustainability of our oceans and the future of aquaculture.”
“This collaboration brings together a powerful alliance of expertise, united by a shared mission to restore European native oysters and support sustainable aquaculture,” said Dr. Nik Sachlikidis, CEO of The Oyster Restoration Company. By leveraging advanced genetic research, sustainable farming practices, and our experience in ecological restoration, we are not only developing disease-resistant oyster strains but also setting a new standard for marine conservation.
“This partnership is a testament to what we can achieve when we work together to protect biodiversity, enhance food security, and rebuild vital ecosystems for future generations.”
