Northeastern white fish is one of the genus Scolionidae, and there are seven or eight species of Scolionidae, most of which are cocky, so it is difficult for laymen to identify them, and it is easy to buy fakes at high prices. There are red fin squid, commonly known as hemp fish and small white fish; Flatfish; Mongolian red carp, commonly known as red tail and red tail tip; Green-tipped red bream, only produced in Wudalianchi; Xingkai green-tipped red carp, commonly known as rolls for grain pot fish; Red pike, only produced in Xiaoxingkai Lake; Crouching red croaker, commonly known as pouting and cocking, is the big white fish in Xingkai Lake; The Songhua River is the white fish and so on. Among them, the outstanding ones are Xingkai Lake white fish and Songhua River white fish. Other fish, or small, or red tail, or black spots on the back, or side turquoise, or back taupe, grayish green, or tail fin inlaid with black edge, or tail fin orange. They * * * have the same characteristics that they are not big, at most one or two kilograms, and their taste and taste are far inferior to those of Xingkai Lake and Songhua River. The * * * similarities between these two kinds of white fish are silvery white skin, pouting and pouting, delicious taste and big size (usually five or six kilograms, more than ten kilograms, twenty or thirty kilograms, and some can reach more than one hundred kilograms).

Guangya called it Kun, and Yu Pian said: "Kun, white fish, also known as Kun." Shuowen said: "Kun, white fish also." "Interview Book" also said: "Among all the frozen fish, white fish is the most beautiful." He added, "Jilin producers are the best." There are similar records in Annals of Changchun County, Annals of Dongfeng County, Annals of Dalai County and Annals of Fusong County and Huinan County compiled during the Republic of China. There are also records about the body color of white fish. Shuowen: "White fish with fine scales, head and tail are high, and the largest is six or seven feet." "Tonghua County Records" contains: "White fish, white, fine scales, the most expensive fish, tribute in the Qing Dynasty." "Huinan County Records" said: "The shape is narrow and flat, with fine scales and the head and tail are upward." "Yingkou Zhi" said: "The mouth is huge and the scales are thin, and the silver carp is long and narrow." Therefore, it can be summarized as follows: fine scales are white, narrow and flat, and the head and tail are upward.

Not only Songhua River, Wusuli River, Xingkai Lake and Jingbo Lake produce white fish, but also the rivers in the whole northeast produce white fish.

The best are Xingkai Lake white fish and Songhua River white fish.

The great white fish in Xingkai Lake and the great white fish in Songhua River are two close relatives. They are not exactly the same fish, with different skin colors and different fin colors. The big white fish in Songhua River has a longer fish head and a smaller eye diameter than that in Xingkai Lake. The lateral line is below the central axis; The dorsal fin is high, about as long as the head; The pectoral fin reaches or exceeds the base of the ventral fin. But the taste and nutritional content of the two are equal. Furthermore, Jilin people call the juvenile of the Songhua River whitefish "island" (island may be Tungusic, which cannot be interpreted in Chinese), while Xingkai Lake has no such thing as "island". At present, other fish sold by vendors in the market are also called "islands", which is another misunderstanding. "Island" is the juvenile of the Songhua River whitefish, otherwise it can't be called "Island".
