About 180 billion pounds (about 81 billion kg) of wild fish are caught each year. This equates to the weight of the entire population of China. The most commonly fished species include cod, salmon, tuna and swordfish – all of which are in danger from overfishing.
More facts about aquaculture:
Asia accounts for about two-thirds of the world’s fish consumption. China alone consumes more than 72 billion pounds (about 32 billion kg) of fish a year, which equates to about 60 pounds (27 kg) of fish per person per year. In contrast, America consumes about 5 billion pounds (about 2.3 billion kg) of fish a year.
In Cambodia, Bangladesh, Indonesia and Ghana, fish accounts for up to half of the protein in the average person’s diet.
During the last 50 years, there has been a 90% reduction in the populations of several large fish species, including tuna, swordfish and sharks.
