The coasts of the Yellow Sea are very densely populated, at approximately 250 people/km². The sea waters had been used for fishing by the Chinese, Korean and Japanese ships for centuries. Especially rich in fish are the bottom layers. About 200 fish species are exploited commercially, especially sea bream, croakers, lizard fishes, prawns, cutlassfish, horse mackerel, squid, eel, filefish, Pacific herring, chub mackerel and flounder. The intensity of fishing has been gradually increasing for China and Korea and decreasing for Japan. For example, the production volumes for China rose from 619,000 tonnes in 1985 to 1,984,400 tonnes in 1996. All species are overfished, however, and while the total catchments are rising, the fish population is continuously declining for most species.
Navigation is another traditional activity in the Yellow Sea. The main Chinese ports are Dalian, Tianjin, Qingdao and Qinhuangdao. The major South Korean ports on the Yellow Sea are Incheon, Gunsan and Mokpo, and that for North Korea is Nampho, the outport of Pyongyang. The Bohai Train Ferry provides a shortcut between the Liaodong Peninsula and Shandong. A major naval accident occurred on 24 November 1999 at Yantai, Shandong, China when the 9,000-ton Chinese ferry Dashun caught fire and capsized in rough seas. About 300 people were killed making it the worst maritime incident in China.
Oil exploration has been successful in the Chinese and North Korean portions of the sea, with the proven and estimated reserves of about 9 and 20 billion tonnes, respectively. However, the study and exploration of the sea is somewhat hindered by insufficient sharing of information between the involved countries. China initiated collaborations with foreign oil companies in 1979, but this initiative declined later.
A major oil spill occurred on 16 July 2010 when a pipeline exploded at the north-east port of Dalian, causing a wide-scale fire and spreading about 1,500 tonnes of oil over the sea area of 430 km². The port had been closed and fishing suspended until the end of August. Eight hundred fishing boats and 40 specialized vessels were mobilized to relieve the environmental damage.

Famous quotes containing the word economy:
“Wise men read very sharply all your private history in your look and gait and behavior. The whole economy of nature is bent on expression. The tell-tale body is all tongues. Men are like Geneva watches with crystal faces which expose the whole movement.”
—Ralph Waldo Emerson (1803–1882)
“Cities need old buildings so badly it is probably impossible for vigorous streets and districts to grow without them.... for really new ideas of any kind—no matter how ultimately profitable or otherwise successful some of them might prove to be—there is no leeway for such chancy trial, error and experimentation in the high-overhead economy of new construction. Old ideas can sometimes use new buildings. New ideas must use old buildings.”
—Jane Jacobs (b. 1916)
“Everyone is always in favour of general economy and particular expenditure.”
—Anthony, Sir Eden (1897–1977)
