Wuyuan carp is a fish in the middle and lower layers of rivers. It mostly inhabits water bodies with rocky bottoms in deep flowing water. It can also live at the bottom of water bodies with slower flowing speed. It has the habit of migrating short distances. After laying eggs in winter, it goes upstream and swims downstream during floods. It has a mixed diet. It often sucks benthic animals and plants from the surface of underwater rocks with its mouth, mainly small snails, mussels, and clams. It also eats a small amount of aquatic insect larvae, water earthworms, and algae. Because sucking is the way this fish feeds, a small amount of sediment is often brought into the intestines. Generally, they need to be over 2 years old to reach sexual maturity, and the spawning season is from November to January of the following year; the eggs are produced in batches, are yellow, sinking, and have a certain degree of stickiness; the spawning grounds are mostly in fast-moving water and a lot of algae.

Wuyuan carp is distributed in the trunk and tributaries of the Xijiang River system and is a common high-quality edible fish in Guangxi. Common ones on the market are mostly individuals weighing 0.5-1.0 kg, and the largest individual can grow to weigh 7 kg. Although the yield is not high, its body is thick and the meat is delicious, so it is regarded as a top-quality economic fish.
Due to the migration habit of this species, dams and gates have been built in each tributary of the river, which hinders the migration of the river and affects its life and reproduction; the discharge of industrial pollution has caused the deterioration of water quality; coupled with factors such as overfishing, its resource volume has declined. , has now become a vulnerable species.
