The yarrow fish in Northeast China are distributed in Heilongjiang, Yalu, Liaohe and Yellow Rivers. Omnivorous fish mainly feed on aquatic insects and its larvae. I like living in estuaries, rivers and streams. After the river thawed, they swam back in droves to lay eggs. Common individuals are 170mm long, and the longest can reach 370mm. Because of its strong reproduction and abundant resources, it is one of the main economic fish in northern China.
