Socio-ecological aquacultures are emerging aquacultures that are "ecologically clean" and have a direct economic impact on disadvantaged communities. Our laboratory is involved in the development of three socio-ecological aquacultures: sea cucumbers (sea cucumbers), seaweeds (algoculture) and corals (coralliculture).
