In the sheltered coastal waters of the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea, there are large fish farms where marine crustaceans such as shrimps, and molluscs such as oysters, are raised in artificial enclosures. These farms are created by floating netted enclosures from a sprawling network of interconnected wooden pathways and platforms. Over these, fishermen have built wooden houses and huts where entire families live.
These pictures were taken in south-eastern China's Fujian province, where there are numerous floating farms that cultivate the sought-after shellfish, a delicacy that is eaten in Asia at banquets and even exchanged as gifts. The marciulture industry—the specialized branch of aquaculture where marine organisms are cultivated in the open ocean—is so large here that it has attracted its own tourist industry.
China is the world’ largest producer and consumer of fish, accounting for one-third of the world's entire fish production and two-thirds of the world’s aquaculture production. Aquaculture, which is the farming of fish in ponds, lakes and tanks, alone accounts for two-thirds of China's total fish output.
China has a very long history of fish farming, going back by more than 3,000 years, but it really took off as an industry in the 1990s.
In recent years, however, production has fallen due to overfishing, pollution and poor practices as the biodiversity is being irreparably damaged. Every year there is a three-month ban on fishing in order to give fish stocks a chance to breed and recover, but it has done little to balance out the numbers
Seafood farms cover the surface of Luoyuan Bay in the Fujian province of China. For a sense of scale, this Overview shows approximately 4 square kilometers (1.5 square miles).
