Shad is a migratory fish that goes upstream to spawn. It gets its name because it enters the river regularly in early summer every year and does not appear at other times.

Produced in the lower reaches of the Yangtze River in China, the Hengjiang shad has the best taste from Dangtu to Quishi. It is known as a treasure in the water in the south of the Yangtze River. It was used as a tribute in ancient times. It is a rare and valuable economic fish in China. The fish is as famous as puffer fish and swordfish, and is known as the "three delicacies of the Yangtze River". Following the alligator, Chinese sturgeon, Baiji dolphin, and mullet, the Yangtze River shad has also encountered a population crisis.

The species in the picture is Clupanodo kelee. Distributed in the South China Sea and East China Sea, it is also found in the middle and lower reaches of the Yangtze River, Pearl River, Qiantang River and other river basins.
