Recently, staff members of Heihe National Forest Park found hundreds of Brachymystax lenok tsinlingensis swimming in large groups in the upstream of the Heihe River in Northwest China's Shaanxi Province.

According to the investigation, this kind of fish has been found in more than a dozen places in the Heihe River, with a number of about two or three hundred each group. Ren Linyuan, deputy director of the Park, said that this was the first time in his term that they had been seen on such a large scale. Brachymystax lenok tsinlingensis, a second-class protected animal, used to be a marine fish species.

Two million years ago, a few individuals migrated from the north frigid zone to the cold-water region of the Qinling Mountains, gradually becoming a unique new species in China with a nickname of "living fossils in water." The fish is also known as the "water aristocrat."

Over the years, as Ren said, the awareness of protecting the habitats of wild animals has been constantly enhanced, and the grand sight of shoals of fish swimming is also the joint efforts of both staff and local people.
