Introduction
The development of mariculture in Greece started in the 80’s. This new activity appeared as a financial opportunity and attracted investors among which few fishers . Private investments supported by EU subsidies contributed to the creation of a high number of aquaculture units of different size in the whole country . The creation of each aquaculture unit was subject to multiple authorizations given by different ministries (fisheries, archaeology, maritime transport, economy, etc.) and an acceptance by the municipality. Since then all aquaculture units were created without any specific marine planning and they often caused negatives reactions from local residents .
Methodology
Through interviews realised in the west coast of Greece with mariculture farmers , civil servants of district and regional fisheries authorities, natura 2000 employees, touristic activity and fishers we tried the capture the nature of the arguments used in favour and against aquaculture during the first period and nowadays. Additional interviews with national authorities (ministries of environment and agriculture and fisheries) and aquaculture experts brought more light concerning expectations about the law related to marine spatial planning which is still not implemented in the country despite the high demand of farmers.
Results
The analysi s of this qualitative data will discuss first the current perspectives of development of mariculture in Greece in relation to marine spatial planning and second, based on the Greek example, provide information to others Mediterranean countries wishing to develop mariculture about how to overcome and mitigate social protests .
