Objectives:

Objective 1 Prepare an update on oyster restoration work carried out since 2005. Prepare a review of the technical requirements and approaches and of the regulatory framework in the light of new disease problems in Scotland

Objective 2 Research potential funding sources and their requirements and time frames.

Objective 3 Through extensive consultation and investigation and with close cooperation from the Native Oyster Steering Group and local stakeholders select suitable sites for the pilot project.

Objective 4 Prepare advice on the most appropriate strategy for native oyster re-establishment in Scotland

Objective 5 Prepare an economic and financial evaluation of the costs for the pilot restoration

Objective 6 Prepare submission of funding application

 Project Summary:

Historically, the native oyster (Ostrea edulis) supported a substantial fishery in Scotland. However, stocks declined dramatically over the last century mainly due to over exploitation. The native oyster is a high value species both as a commercial product in high demand and as a native species forming highly productive reefs (under optimal conditions). For these reasons the native oyster is the only aquatic species on the SNH Species Action Framework, the Scottish Biodiversity list and a Priority Species on the UK Biodiversity Action Plan as a threatened species of socio-economic value requiring action to ensure sustainable use. Considerable scientific research on the historical and current status (abundance and distribution), and biology of the native oyster and its management has been conducted. Recent restoration success and valuable lessons learnt from initiatives elsewhere in Europe and USA, all
combine to show that restoration of native oysters in Scotland is feasible.

The main objective of this project is to develop and deliver a funding application for such a venture on a pilot scale. Phase 1 would be to identify sources of funding projects of the required period of time – at least 5 years. It should also identify the support and commitment of all stakeholders since there are a number of areas where the project could fail without this. It would also be necessary to identify likely sites since this would be essential for preparation of the proposal. The question of location is paramount but arguably consideration should be given to a number of options. The recent advent of the native oyster disease, Bonamiasis in Scotland raises limits as to where such a project could be sited, and more significantly where restocking oysters should be sourced or alternative methods used. A detailed plan of work will be prepared for such a project drawing heavily on previous and current regeneration recovery attempts of Ostrea spp and stakeholder participation will be formally linked in at the latter stages with a workshop. Phase 2 will be the preparation and submission of the application(s) for funding providing a satisfactory outcome from the initial phase has been achieved.
