Grouper is more precious than horsemouth.

It is distributed in rivers from the east to Heilongjiang Province, and is distributed in large and small tributaries in the middle and upper reaches of various water systems in Zhejiang Province. Horsemouth not only has strong fecundity and fast growth rate, but also has delicious meat and is loved by consumers. However, due to excessive fishing intensity and changes in the ecological environment in recent years, wild horsemouth resources in the Oujiang River Basin have become very scarce.
