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

在全球范围内，恢复牡蛎双壳类的势头正在增强。在欧洲沃茨，本地牡蛎Ostrea edulis是广泛恢复工作的重点，自2015年以来，蓝色海洋基金会（BLUE）一直在索伦特海峡领导恢复本地牡蛎的工作。索伦特海峡历史上曾是英国最大的牡蛎渔场，但自20世纪70年代以来一直在下降，自2013年以来一直关闭捕鱼。索伦特系统是一个很好的模型，可以帮助我们了解如何最好地恢复一个已经不复存在的栖息地;这些见解可以扩展到更广泛的欧洲和其他地区。到目前为止，我们的工作已经比较了小规模养殖的亲牡蛎在码头吊笼养殖与在海床上的高架礁养殖的性能1，并探讨了本地牡蛎性别决定和配子发生的环境控制2 -3。研究还量化了牡蛎提供的营养调节和从环境中去除微塑料的服务。该奖学金将量化朗斯通港、昂布尔河和怀特岛纽敦港的Relaid牡蛎提供的惠益，包括几种生态系统服务，然后将通过监测量化该战略的影响。索伦特海峡的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.
