The Amur minnow or Lagowski's minnow (Rhynchocypris lagowskii) is an Asian species of small freshwater cyprinid fish. [1] It is found from the Lena and Amur rivers in the north to the Yangtze in China in the south, and in Japan. [2]
The Amur, or Heilong Jiang, is the world's tenth longest river, forming the border between the Russian Far East and Northeastern China. The Amur proper is 2,824 kilometres (1,755 mi) long, and has a drainage basin of 1,855,000 km2 (716,000 sq mi). Including its source river Argun, it is 4,444 km (2,761 mi) long. The largest fish species in the Amur is the kaluga, attaining a length as great as 5.6 metres (18 ft). The river basin is home to a variety of large predatory fish such as northern snakehead, Amur pike, taimen, Amur catfish, predatory carp and yellowcheek, as well as the northernmost populations of the Amur softshell turtle and Indian lotus.

The kaluga, also known as the river beluga, is a large predatory sturgeon found in the Amur River basin. With a maximum size of at least 1,000 kg (2,205 lb) and 5.6 m (18.6 ft), the kaluga is one of the biggest of the sturgeon family. Like the slightly larger beluga, it spends part of its life in salt water. Unlike the beluga, this fish has 5 major rows of dermal scutes and feeds on salmon and other fish in the Amur. They have gray-green to black backs with a yellowish green-white underbelly.
