What varieties and characteristics of cold-water fish are found in Northeast China?

In Northeast China, apart from a few coastal cities in Liaoning Province, all other cities are inland cities, which also makes the aquatic products of Northeast China mostly freshwater aquatic products. Among freshwater fish there is a special category, collectively known as cold-water fish. The concept of cold-water fish is rather general, roughly meaning that they find it difficult to survive above a water temperature of 20 degrees Celsius. So what varieties of cold-water fish are there in Northeast China?

1. Sturgeon and kaluga

Sturgeon and kaluga is actually a collective name for two kinds of fish, namely the Amur sturgeon (Acipenser schrenckii) and the kaluga sturgeon (Huso dauricus). Wild Amur sturgeon and kaluga sturgeon have been listed as one of the nationally protected animals, but these two kinds of fish can be artificially farmed and can still be bought and sold on the market. The most precious part of sturgeon and kaluga is their roe; the caviar made from their roe enjoys a great reputation internationally. Their flesh is also rather delicious and is a food greatly loved by local people.

2. Chum salmon

Chum salmon is a relatively precious cold-water fish. This fish is rather special: it is born in the sea and dies in the river. The so-called born in the sea refers to growing in the sea, not being born in the sea. Newly hatched chum salmon swim to the sea to grow, and when they grow to spawning season they return to their birthplace to spawn and then die, ending their lives. People call this behavior migration. The precious part of chum salmon is also its roe; its roe is red, crystal clear, like little red pearls.

3. Taimen

Taimen is a relatively large freshwater fish; an adult fish can even reach a body length of more than one meter, and in China it mainly lives in the Heilongjiang River basin. Taimen is relatively precious because fishermen catch them heavily, so the number of taimen bred and the number caught cannot reach a balance. Today the number of taimen is dwindling day by day, and the taimen people can catch are also fewer and fewer. If it is not controlled, one day it will completely disappear from people's sight.

4. Dace

Dace is also a kind of freshwater fish. It is relatively small in size; an adult dace generally weighs around two liang. In some areas of Jilin Province, dace is called "Yalu", and the Yalu at the opening of the river is the most famous. Every year in April, when the river just opens, these areas will certainly taste the Yalu at the opening of the river. Simply stewed is enough, and the taste is especially delicious.

5. Pike

Pike is also a kind of cold-water fish. In China, there are mainly two kinds of pike distributed, namely the black-spotted pike and the white-spotted pike. Pike has excellent flesh, and its market value is also relatively high. Pike is a carnivorous fish. It is fierce by nature and not only feeds on small fish in the water but also attacks some birds. Pike has always been a target for fishing enthusiasts, because it is rather cunning, so many fishing enthusiasts use it to judge whether their fishing skills are superb.
