The sustainable management of fisheries and conservation of marine living resources through the ecosystem approach is a societal issue of global dimension. More and more, data is needed to support evidence-based decision making and adaptive management, a challenge that no single institution or country can address in isolation. The European Union's programme for e-infrastructures and data infrastructures has been the pathway to integrating data services and tools in a seamless way, increasingly at large scale. As a data management infrastructure, iMarine (http://www.i-marine.eu) ensures that computational resources, specific tools, and data services are open to many different actors and complementary initiatives. With a long-term vision for providing the comprehensive data management solutions required to support the full policy cycle of the ecosystem approach to fisheries at a global scale, iMarine proposes a public partnership centered business model
