Pelteobagrus fulvidraco, commonly known as yellow wax fish, stickleback fish and yellow croaker, is a common freshwater economic fish in rivers and lakes in China.

The local names are also called: Huang Latin, Yu Song, Ga Yu and Ga Yazi. Stickleback is a small wild economic fish with a wide mouth, a slender body, a sticky whole body and a beard. Its meat is tender, delicious, prickly and fatty. Protein content 16. 1g, fat 0.7g, calcium and phosphorus content is the highest in rivers and fishes, which is beneficial to body building and milk production.

There are many names. Shanghai people call it "Angniu". Suzhou people call it "king nail head"; Northeast people call it "Ga Ya Zi"; Ningbo people call it stickleback. All these names are based on the color of its fish, the shape of its pectoral fins and dorsal fins like long needles, or the "quack" sound it makes when swimming in groups. However, Sichuanese call it "Yellow Latin". Think about it carefully, these three words really cover the color, shape and sound of this fish, and the simplicity of Sichuan people's language is well-deserved. But the most unique thing is the "yellow duck call" of Hunan people.
