:Based in Montpellier in the south of France, Ecocean's team has for fifteen years been focused on ways of making sustainable use of an untapped marine resource: post larvae of coastal fish and marine animals. The company also provides scientists with new tools for assessing the state of biodiversity and marine ecosystems. Since 2009, Ecocean and its partners have been working on processes designed to restore shallow coastal waters impacted by developments and return them to their role as nursery habitats. These solutions are aimed at commercial port and marina operators keen to incorporate biodiversity into their environmental policy and the way they manage their infrastructures. These pioneering processes represent a new approach to ecological engineering and protection of marine ecosystems. Already well established in the Mediterranean, we are currently looking for partners to help us develop and adapt our solutions for other marine zones.
