Just 9% of the millions of tonnes of fish caught by China's giant fishing fleet in African and other international waters is officially reported to the UN, say researchers using a new way to estimate the size and value of catches.

Fisheries experts have long considered that the catches reported by China to the UN's Food and Agriculture Organisation (UNFAO) are low but the scale of the possible deception shocked the authors. ... Read more about Chinese fishing fleet in African waters reports 9% of catch to UN
