The objective of this scientific project is to estimate the contribution of shellfish farming to microplastic pollution in the Thau lagoon and to produce recommendations to ensure the sustainability of this practice and to reduce its impact.
For one year, the association will carry out monthly monitoring of the microplastics present in the water column, sediments and bivalves. Samples taken in 2011 will allow the state of the pollution to be compared in 2021.
A physico-chemical study will then be carried out to assess the microplastic contamination linked to the ageing of the material used in shellfish farming. A survey of professionals on their practices will make it possible to identify the materials to be tested, to understand their use and their ageing rate. A guide to good practice will then be produced from the results of this study to help shellfish farmers implement more sustainable practices.
Finally, a large-scale communication campaign will be conducted around the project. Stop motion films will be produced and broadcast.
