Mainly in Heilongjiang, Wusuli River and the upper reaches of Songhua River.

There is artificial breeding in Huaihua area of Beijing.

Precautions for breeding salmon:

Water quality: Salmon is a saltwater fish that lives in the sea. Therefore, attention should be paid to keeping the fresh water clean when it is cultured in fresh water. It is absolutely not allowed to be cultured casually in ordinary ponds, rivers and fish ponds.

Density: The stocking density of salmon should not be too high, and it is best to stock about 25-50 grams of salmon per cubic meter with 45-50 fish. The growth rate of salmon is still very fast. When 50 salmon are fed for about 5-6 months, it can reach about 1-2 kg. The breeding density is too high, and too much stocking density will affect the growth rate of salmon.

Feed: It is best to use granular feed, and salmon can better help it domesticate after adapting to this feed. When the water temperature is lower than 8 degrees, feed it twice a day, once at around 8: 00 a.m. and once at around 5: 00 p.m. If the water temperature is around 8- 15 degrees, feed it once a day.

Water temperature: Salmon is a kind of cold-water fish because it lives in the sea, so the requirements for water temperature are very high. The best water greenhouse should be around 13- 15 degrees, which is the favorite temperature of salmon, and the lowest temperature should be controlled at around 8 degrees.
