Researchers from New York University have tracked illegal fishing activities on the high seas using satellite data and other analytical tools, revealing over 90 companies from Russia, USA, Great Britain, Spain, the Netherlands, China, Taiwan, and South Korea as the most active illegal miners and sellers of fish, controlling about 60 percent of the fish resources in the World Ocean. These companies take advantage of the lack of control in fishing areas, operating outside of national laws and regulations. The researchers plan to share their findings with law enforcement agencies to combat unregulated fishing and its impact on declining marlin, swordfish, and tuna populations.
