: 126 million tons available for human consumption, the lowest fish consumption had Africa (9.1 million tons), while Asia counted for to-thirds of total consumption (85.4 million tons), of which 42.8 million tons was consumed outside China.

2009: fish accounted for 16.6% of the world population's intake on animal protein and 6.5% of all protein consumed.
2004 to 2010: anchoveta (Engraulis ringens) decrease from 10.7 million tons to 4.2 million tons (Southeast Pacific).
About 600 aquatic species are raised in captivity in about 190 countries (there are currently 197 countries).
2010: Global production of farmed food fish was 59.9 million tons, valued at $119.4 billions.

Top then producing countries (for farmed fish) account by quantity to 87.6%, valued of 81.9%.

Pollution of the marine realm

- 5 times more garbage is dumped into the ocean than all the fish caught on a commercial basis
- 60 to 80% of marine litter: plastic
- 1975: World fishing fleet dumped approx. 135,000 tons of plastic fishing gear and 23,600 tons of synthetic packaging material (Cawthorn, 1989)
- Study in North Pacific: 8 out of 11 birds examined had plastic particles in them
- Plastic found in 86% of all sea turtles, 44% of all seabird species, and 43% of all marine mammals (Laist, 1997)

General facts

- Extinction rate increased between 1,000 and 10,000 times of the natural rate (Lovejoy, 1997)
