The Amur grayling (Thymallus grubii) is a freshwater species of fish of the family Salmonidae, found in the Amur drainage in Russia and China and also the Onon and Kherlen drainages in Mongolia. It is sometimes difficult to differentiate the species with the Lower Amur grayling (Thymallus tugarinae). It is an edible fish in Russian far east and Heilongjiang Province of China.[1]

Description

The body of Amur grayling is usually dark, with its back being slightly purple. There are some small dark spots on the sides of the body. The edge of the dorsal fin is purplish red mixed with some spots.[2] It can reach a maximum length of 31.3 cm.[3]

Life cycle

In winter, adult Amur grayling are found in deep parts of mountain streams. While in summer, they are usually found in clear streams flowing slowly with thick aquatic weeds.[4] Most Amur grayling is feed on benthic organisms and insects.[2] They form schools while breeding in clear, fast-flowing streams.[2]
