• The Workshop main conclusions point towards the maintenance of extensive and semi-intensive production systems. Although potentially less profitable than intensive systems, extensive and semi-intensive systems generate social, patrimonial and environmental gains that intensive systems cannot generate. According to a socioeconomic study carried out within the SEACASE Project, in the long-term it is more advisable for the society to invest in this type of economic activity, which contributes to the maintenance of functional coastal ecosystems (in terms of biodiversity, cultural heritage, landscape, etc.), rather than abandon these ecosystems and try to restore them afterwards.

• Technical improvements that can be directly adopted by the industry were highlighted during the Workshop. Including the use of integrated multi-trophic systems, which combine several production methods and different species of fauna and flora, and reduce environmental impacts. Equally relevant was the work done and the discussions about the nutritional characteristics and the quality of aquaculture products that come from non-intensive systems, and the development of certification systems and codes of conduct.

• The SEACASE Project counted with the participation of 12 research institutions from five Southern European Countries: Portugal, Spain, France, Italy and Greece. During the three years of the Project, one of its main priorities was to collaborate and establish partnerships with the aquaculture industry in all the countries involved. The SEACASE Project analysed a broad range of extensive and semi-intensive production systems and identified as a priority the valorisation of these production methods and the development of efficient tools to increase their competitiveness and productivity.

• Nowadays, researchers and the aquaculture industry are increasingly approaching each other to exchange information, experiences and technical knowledge. Collaboration between these two groups is likely to increase and become more efficient and able to significantly contribute to the development of aquaculture. Initiatives, like the SEACASE Project, definitely give a significant contribute towards this approach.
