China is now the largest fishing power in West Africa. But according to the environmental organisation Greenpeace, that's not a good thing. They say reported catches have increased almost twelve times to 3.6 million tonnes and illegal fishing is also becoming more common. They point to China's long-distance fishing fleet, numbering over 2,000 vessels, which is ten times the size of America's.
