Développer l’aquaculture multi trophique intégrée sur l’Arc Atlantique français : une étude sur l’acceptabilité sociale

Abstract : European aquaculture is facing several challenges, including environmental impacts, the availability of space, livestock diseases and the massive use of antibiotics. One of the ways to overcome these problems would be to turn to Integrated Multi Trophic Aquaculture (IMTA), a concept of polyculture based on the conversion of nitrogenous waste from farms by other extractive species, which would be able to benefit a higher social acceptability. This report studies the influence of social acceptability on the development of IMTA projects on the French Atlantic arc. After the realization of a state of the art on the AMTI and on the social acceptability, 36 interviews were made from selected case studies on the French Atlantic arc. An analytical model was constructed to analyze these results and identify trends, and bibliographic studies were used to complete the analysis. It appears that aquaculture is promoted at the supranational scale through development programs. However, supranational objectives do not always fit well with national plans (public policy, regulation, spatial planning). The decision-making processes put in place are incomplete and favor only an acceptance instead of a real social acceptability integrating all the stakehodlers. At the local level, the project owner must assimilate the interactions between stakeholders and must formulate in a participatory and transparent way his activity, by consulting before the decision-making processes. The IMTA shows environmental characteristics perceived very positively by the interviewees. On the other hand, current scientific evidences on IMTA are insufficient to validate the process (especially in an open environment).
