Developing protected areas and corridors for shark migration is also important. Last month, US President Barack Obama extended the maritime boundary of the Pacific Remote Islands Marine National Monument from 50 miles to the 200-mile limit, effectively merging the region’s national parks into one massive protected area, in which commercial fishing is prohibited.
划定鲨鱼迁徙的保护区和走廊也有着非常重要的意义。去年，美国总统奥巴马批准将太平洋偏远岛屿海洋国家纪念碑的海上边界从20英里拓展至200英里的上限，实际将该地区的国家公园有效连成了一片禁止商业捕鱼行为的巨大的保护区。
