A new research project aims to quantify the ecosystem services provided by Ireland’s shellfish aquaculture sector.

Called ShellAqua, the project has four goals, each formed around producing tangible outputs for society, industry and wider stakeholders:

  1. Develop an ecosystem services-based tool using operational and monitoring data for case-study shellfish aquaculture sites. These datasets will be developed using laboratory scale experiments and on-site monitoring.
  2. Develop life cycle datasets on mussel and oyster production in order to produce a tool that will allow operators and producers to continue monitoring their environmental performance after the project concludes.
  3. Assess the economic benefits of the outputs from the preceding goals. The results of the previous work packages will be used to estimate the value of the ecosystems services provided by shellfish aquaculture at the case-study sites.
  4. Engage in knowledge transfer of methods, results and approaches. Industry partners and stakeholders will be actively engaged throughput the project through a series of workshops and training events.

ShellAqua is one of the projects that recently received funding by Bord Iascaigh Mhara (BIM), under the European Maritime and Fisheries Fund funded Knowledge Gateway Scheme. It’s being led by the Morefish group, an aquaculture research unit based within the Ryan Institute at NUI Galway.

Industry partners who supported the ShellAqua application included Coney Island Shellfish, Blackshell Farm and Kelly Oysters. The application was also supported by the community-based organisation Cuan Beo and the Irish Farmers’ Association Aquaculture. The locations of these sites will allow for the development of datasets and profiling of mussel (Mytilus edulis) and oyster (Crassostrea gigas) aquaculture in Galway Bay, Clew Bay, Sligo Harbour and Drumcliff Bay.

Michael Mulloy, chairman of Irish Farmers’ Association Aquaculture and owner of Blackshell Farm, said in a press release: “That the ShellAqua project is valuable for the future and helps take the industry in the direction we need to go. The project will provide the tools we need to verify the sustainability of our industry.”

Frank Carter, of Coney Island Shellfish Ltd, said: "Coney Island Shellfish Ltd supports the ShellAqua project in its aim to equip the shellfish industry to assess its own environmental impact and, using the tools developed by the project, demonstrate its ability to contribute positively to the climate change agenda. In so doing, the industry will be empowered to actively engage in the drive towards environmental protection and the preservation of biodiversity, while continuing to produce a healthy and sustainable food source."

Alan Kennedy, Morefish and ShellAqua project manager at NUI Galway, added: “This is another example of how proactive engagement between researchers and the aquaculture sector can support the sustainable development of the industry with significant potential benefits for broader society.”

Diarmuid Kelly, chair of Cuan Beo, said: “While we have always known the importance of having healthy bivalve populations within our bays, this project will provide us with the scientific evidence of the ecosystem services provided by such communities. It will also give us the necessary information needed to inform policy makers of the benefits of protecting shellfish waters.”
