 We need the oceans. They help regulate our climate and produce oxygen for us to breathe. They provide food and jobs for millions of people. To keep the oceans healthy, we need to manage the marine environment responsibly, as overfishing, pollution and climate change are putting pressure on biodiversity and ecosystems. The Common Oceans Program is a global alliance, promoting sustainable fisheries and conservation of marine biodiversity. Tuna is a highly migratory fish species. They do not know any boundaries. If stocks aren't managed well, traditional fisher folk, like pole and line fishers in the Maldives, will bear the consequences. The Common Oceans Program works to ensure that all major tuna stocks are fished at sustainable levels. It also aims to reduce negative impacts of tuna fishing on marine ecosystems. The port of Ligo, in Spain, has a major fishing fleet. Some of its boats venture out far onto the Atlantic Ocean. Deep sea fisheries bring economic benefits and employment. But stock depletion and impacts on ecosystems raise concerns. The Common Oceans Program aims to preserve biodiversity by reducing harmful practices and decreasing by-catch. At the moment, the citizen can already know where the fish is coming from. It is a very large chain, a chain from the high seas. It has arrived here and then distributed to the international and international markets. Well, we have the IUU regulation. So the fish that's imported that you'll have seen coming into the Vigo fish market and coming into the fish markets around Europe should be caught from sustainable legal catches. So all fisheries, you've got the same challenges. You want to make sure that you've got enough fish stocks left that are going to be able to reproduce. So you have to have that really good science, what can be taken from the stocks. Then you have to know that the vessels are taking what they should be taking. When you try to do an investment, you try to reduce your risk as the maximum. If you are fishing in an area that is totally unmanaged and unregulated, your risk is really high because there is the chance that the stock might collapse in two, three years. The people who depend most on the sustainability of fisheries are fishermen. So if a stock collapses, it's the fishermen who suffer the most. Sustainability is also becoming a market need. So if you know that a fish is coming from a fishery that cannot show that it's sustainable, you are going to be closing some of the doors of the market and you are going to end up with less market access. The Common Ocean program is committed to conservation of the Sargasso Sea, a unique and highly biodiverse high seas ecosystem. This is one example of the collaborative and cross-sectoral partnerships that the program supports to preserve biodiversity throughout the areas beyond national jurisdiction. A new treaty on conservation and sustainable use of marine biodiversity beyond national jurisdiction, known as the BBNJ agreement, could be a game changer. Strong partnership are crucial for the sustainable use and management of our common oceans.
