Since 2002 the WorldFish Centre has been working in collaboration with the Marine Resources Assessment Group (MRAG), Aquae Sulis Ltd (ASL),, the FAO, and the Mekong River Commission (MRC) to develop guidelines for designing data collection and sharing systems for co-management fisheries. The development of these guidelines has focussed around an eight stage participatory design process which aims to provide co-managers, at all levels, with data and information they require to support the management process.
