Bohai Bay

Bohai Bay (simplified Chinese: 渤海湾; traditional Chinese: 渤海灣; pinyin: Bóhǎi Wān) is one of the three major bays of the Bohai Sea, the northwestern and innermost gulf of the Yellow Sea.

It is the most southerly water in the northern hemisphere where sea ice can form.

[4] Fisheries were traditionally some of the richest in China, fed by enormous sediment runoff and extensive shallows to serve as hatcheries.

Pollution, eutrophication, habitat destruction caused by land reclamation, and intense overfishing have resulted in a collapse of stocks, and a decline of trawl catch per unit of effort (CPUE) from 138.8 kg/net.hr to 11.2 kg/net.hr from 1959 to 1998.

Land reclamation in Tianjin and in Caofeidian have greatly changed the littoral zone, and destroyed much of the area's wetlands.
