The Indian Ocean is home to some of the world's richest tuna fishing grounds. They are a valuable resource to coastal states and an attractive fishing opportunity for foreign fleets. Unfortunately illegal and unreported fishing is a major problem in the region. For countries like Mozambique, monitoring their waters is not an easy task due to resource constraints. Greenpeace has recently been working with the Mozambican government, providing fisheries officials with a platform to monitor and patrol the country's waters.
