Forth Marine Hatchery
Project Background

The Forth Marine Hatchery is dedicated to restoring two keystone species, native European flat oysters and European lobsters, in the Firth of Forth. The project enhances biodiversity, supports marine ecosystem resilience, and provides hands-on experience for the next generation of marine scientists.

Based near North Berwick, the hatchery facility includes a full scale lobster hatchery and several oyster spatting ponds, an innovative and cost effective native oyster restoration method. A new central operations hub now brings staff and volunteers together on-site, enabling more coordinated and efficient project delivery.

Project Need

The European flat oyster (Ostrea edulis) once thrived in the Firth of Forth but is now functionally extinct locally. Its loss has removed critical ecosystem services, such as water filtration, carbon cycling, and habitat creation. Restoration is limited by the absence of a dedicated east coast hatchery, existing efforts rely on sourcing oysters from other regions, which increases the risk of disease and invasive species transfer. There is also a severe lack of supply for restoration purposes.

Similarly, European lobsters (Homarus gammarus) are a vital species ecologically and economically, but face pressure from heavy fishing and environmental degradation. Hatchery work can play a key role in helping rebuild wild stocks and supporting the future of local inshore fisheries.

The need is also educational and economic. Scotland is seeing increasing demand for practical marine conservation opportunities, yet few hands-on training routes exist for aspiring marine scientists or coastal communities.

Project Description

The Forth Marine Hatchery is a pioneering conservation and aquaculture facility near the Firth of Forth, focused on restoring the European flat oyster across Scotland’s east coast. The hatchery will produce healthy, locally sourced oyster stock, removing the need to transport oysters from other regions and eliminating the associated risks of disease and invasive species.

Central to this work is our innovative pond-based “spat on shell” system, a cost effective method proven for commercial oyster production in Ireland but now being applied for ecological restoration at scale for the first time in Scotland.

Alongside oyster restoration, the hatchery also rears lobster juveniles for release into local waters. This will support the recovery of heavily fished stocks and help sustain a species that is ecologically and economically vital to East Lothian’s coastal communities.

The hatchery will also act as a centre for research, education, and community engagement.

Project Impact

  • Restoration of a nearly extinct keystone species in the Firth of Forth.
  • Enhanced marine biodiversity and the creation of nursery habitats for fish and other wildlife.
  • Improved water quality—each oyster can filter up to 200 litres of water per day.
  • Stabilisation of carbon in the marine environment through shell formation and seabed interaction.
  • A scalable, biosecurity solution to support future restoration projects across the Scottish east coast.
  • Restoration of overfished lobster populations.
  • Community benefits through education, volunteering, and citizen science.

We measure success through a range of qualitative and quantitative tools, including species survival rates post-release, number of spat produced, engagement metrics, and environmental monitoring in partnership with academic collaborators.
