Quantifying the status and success on restored native oyster Ostrea edulis beds in the Solent.

在全球范围内，双壳类牡蛎的恢复工作正在蓄势待发。在欧洲水域，本地牡蛎Ostrea edulis是广泛恢复工作的重点，在索伦特，蓝色海洋基金会(BLUE)自2015年以来一直在领导恢复本地牡蛎的努力。索伦特在历史上代表着英国最大的牡蛎渔业，但自20世纪70年代以来一直在下降，自2013年以来总体上一直禁止捕鱼。索伦特系统代表了一个很好的模型，可以理解如何最好地恢复不再存在的栖息地；可以扩展到更广泛的欧洲和更远的地方的见解。到目前为止，我们的工作已经比较了码头悬浮网箱养殖亲贝的小规模高位养殖和海床高位珊瑚礁养殖的性能，并探索了本地牡蛎性别决定和配子发生的环境控制2-3。研究还在量化牡蛎为营养调节和微塑料从环境中移除所提供的服务。该奖学金将量化再援助牡蛎在兰斯通港、汉布尔河和鬼魂岛纽敦港提供的效益，包括几项生态系统服务，然后将通过监测量化该战略的影响。索伦特的这个项目是欧洲最大的项目之一。

Globally, the restoration of ostreid bivalves is gaining momentum. In European waters the native oyster Ostrea edulis is the focus of extensive restoration efforts and in the Solent, Blue Marine Foundation (BLUE) have been leading efforts to restore native oysters since 2015. The Solent historically represented the UK's largest oyster fishery, but has been in decline since the 1970s and generally has been closed to fishing since 2013. The Solent system represents a good model to understand how best to restore a habitat that no longer exists; insights that can be scaled to the wider Europe and beyond. Thus far our work has compared the performance of small scale elevated culture of broodstock oysters in suspended cage culture in marinas with elevated reef culture on the sea bed1 and has explored the environmental controls of sex determination and gametogenesis in native oysters2-3. Research is also quantifying the services offered by oysters for nutrient regulation and microplastic removal from the environment. This studentship will quantify the benefits, including several ecosystem services, provided by relaid oysters in Langstone Harbour, the River Hamble and Newtown Harbour on the Isle of Wight, and will then quantify the impact of that strategy through monitoring. The project in the Solent is one of the largest in Europe.
