The next time someone tells you to invest in China, remember the fable of the Canadians and the fish.
Scientists at the University of British Columbia made a shocking discovery at the end of last year.
Contrary to the worries of the environmentalist movement, the United Nations had widely accepted statistics showing that fish stocks rose by 350,000 tonnes a year during the 1990s.
However, according to an independent report by British Columbia researchers Dr Daniel Pauly and Dr Reg Watson, global stocks of fish were actually falling by 400,000 tonnes per year.
How on earth did this statistical mismatch occur?
Three out of every 10 fish caught in the world comes from the waters around the mainland and, as a result, so does much of the data used to measure fish stocks.
