Infection kills endangered Chinese sturgeon at Hong Kong’s Ocean Park
Fish, from one of nation’s most protected species, was observed to have reduced appetite and signs of a gill infection
A rare Chinese sturgeon raised in Hong Kong’s iconic Ocean Park died on Tuesday due to severe disease.
The captive-bred fish was a second filial generation Acipenser sinensis, a species dating back 140 million years and found on the International Union for Conservation of Nature’s “red list” of endangered animals.
It died at 8.45am after failing to recover from severe multi-systemic infectious disease despite continuous medical treatment and supportive care.
Since the first batch of these fish – which are among the nation’s most protected species – arrived from the mainland in 2008, 11 individuals have died, including the most recent case.

Ten captive-bred members of the critically endangered species remain at the park’s Chinese Sturgeon Aquarium – Yangtze Exploration attraction, as part of a research collaboration with the Yangtze River Fisheries Research Institute.
