Breeding area in Bohai Sea slated to get better protection

China's only national nature reserve for spotted seals will be narrowed for more effective protection, an official with the protective administration said.

As the breeding area for spotted seals in China, the reserve covers an area of 6,722 square km in the Bohai Sea near Changxing Island of Dalian, Liaoning province.

"We are planning to make some adjustments and optimization for more effective measures and better protection by narrowing down the range and avoiding human interruption in the core area," said Wang Tao, director of the administrative bureau of the Dalian Spotted Seal National Nature Reserve.
