China has resumed imports of Japanese koi, removing a ban imposed amid viral disease outbreaks at Japanese fishing farms in 2003, authorities in Shanghai said Tuesday.

The first shipment of 20 Japanese koi arrived in Shanghai Friday and is undergoing quarantine inspection at the airport, the Shanghai Entry-Exit Inspection and Quarantine Bureau said in a press release.

After the inspection, the carp will be put under quarantine for another 30 days at a designated fish farm for further observation, it said.

China suspended imports of the Japanese aquarium carp in 2003, when a major outbreak of carp herpes, a virally transmitted disease, ruined many carp farms in Japan.

China's aquarium carp market reported a turnover of approximately 10 billion yuan (1.44 billion US dollars) in 2015. Resumption of imports from Japan is expected to help local fish farmers improve breeding.
