Around 120,000 artificially-incubated sturgeon fry have been released into the Heilong River, the boundary river between China and Russia.

Acipenser schrenckii, commonly known as Amur sturgeon, is an endangered species of fish that has high economic value and is native to the Heilong River, also known as the Amur River, according to the Heilongjiang provincial fisheries administration in northeast China.

In early June, the Heilongjiang aquatic breeding center transported live embryos of the Amur sturgeon from the city of Fuyuan. After artificial incubation and breeding for over 50 days, the average length of each fish fry reached about 7.8 cm.

It was the first time to discharge the fry to the upper reaches of the Heilong River, aiming to better preserve the local ecological balance and sturgeon numbers.

Previously, fry were released into middle reaches of the river.
