Morning News reporter Yu Wenyan reporting from the southern tip of the Lofoten Islands, Norway 

Today is World Oceans Day. This year's theme is: oceans and sustainable development. One of the richest countries on earth, in terms of marine resources, is Norway, which boasts a world-class fishing industry. Across the Arctic Circle, a visit to the Lofoten Islands helps one understand how Norway takes measures to preserve marine resources through sustainable development. Norway sets restrictions on the total cod and other fish caught, and fishing vessels over 24 meters in length are fitted with GPS devices to track sea fishing record catches. Those caught over-fishing face revocation of fishing permits and other punitive measures. In addition, trawling and other mass fishing practices are prohibited. These measures help to ensure the sustainable development of fish and other marine resources.
