Identification of relevant social impact indicators for a Social Life Cycle Assessment (SLCA) is still difficult and poorly documented (Jorgensen, et al, 2009). In aquaculture systems, the studies based on social aspects are essentially focused on manpower or on conflicts with other activities . In the PISCEnLit project**, we aim to broaden the vision of social impacts of fish farming systems using a new approach of SLCA. We studied fish farming pond systems in France (Lorraine and Brenne) and Indonesia (Tangkit Baru and Kumpeh Ulu in Sumatra island). In this study, we focused on the choice of the impact categories using the participation of stakeholders (James et al., 2002) by the identification and selection of the relevant social impacts to be assessed. From a practical viewpoint, the proposed approach consists in implementing surveys and focus groups about the social representations at different stages of the assessment process. Through this process, the opinions of the stakeholders about potential or real social impacts of aquaculture may be taken into consideration. However, the technical construction of the relevant impact indicators allowing evaluation of the impacts still have to be done by the researchers.
