4. Growth conditions: the best growth water temperature is 22~26 ℃. Salinity: 1.8%~2.5%, dissolved oxygen: above 5ml/l
5. Product introduction: Large yellow croaker is commonly known as yellow croaker. Daxian. The head is blunt and pointed, with large oral fissure, tip position, inclination, and no protruding snout. The outermost row of teeth in the upper jaw is expanded to canine teeth, and the front teeth are larger but sparse, and there is no tooth in the front center.

The length of the second hip fin spine of the big yellow croaker is greater than or equal to the eye diameter, while the small yellow croaker is smaller than the eye diameter.

6. Product history: There was a legend that yellow croaker turned into wild duck in autumn, because there were stones in the head of wild duck. The generation of this legend is probably related to the ancient people's ignorance that yellow croaker is a migratory fish. The yellow croaker comes in spring, and it is a reproduction migration. At the end of autumn and the beginning of winter, it goes to the southeast sea for winter. Our ancestors did not know the migratory characteristics of yellow croakers, and they suddenly disappeared in late autumn and early winter; At this time, a large number of wild ducks, as migratory birds, flew there. They just had stones on their heads, so they thought they were made by yellow croakers. Apart from that, from this legend, we can imagine that there were many wild ducks in Jiangsu, Zhejiang and Shanghai, and the ecological environment was excellent.
