How to raise salmon?

Salmon is the kind of sashimi we usually eat. According to recent news reports, most of the salmon we eat in the future will be farmed freshwater salmon. Because now the market demand for salmon is increasing, but the time for artificial breeding is limited, and it is difficult to catch wild ones. So started a large number of salmon culture tide, but this is a new aquaculture industry, many friends do not know how to raise. Today, the editor brings you the method of raising salmon.

1. Variety

Salmon is a common name for some salmon fishes. Salmon includes Atlantic salmon, Pacific salmon and other fish. These salmon are all called salmon. Therefore, good varieties should be selected before breeding, and high-quality varieties can make everyone get twice the result with half the effort in the subsequent breeding process, because most of the artificial farming is freshwater culture, so the varieties must be suitable for fresh water and strong disease resistance. otherwise, it is not conducive to the economic benefits in the later stage.

2. Water quality

Salmon itself lives in the sea, so if you use fresh water for aquaculture, you should keep the freshwater clean. Do not arbitrarily draw water from certain ponds or rivers and cover the place where salmon is raised with new cement. After drying, the pond needs to be soaked in water for at least two months. If the old cement pond is used, the interior of the pond should be disinfected with fungicide 7-10 days before the fry is stocked. The water depth of the pond should be about 1-1.5m.

3. Density

The culture density must not be too dense, with a maximum of 50 salmon of 30-50 grams per cubic meter, because the growth capacity of salmon is very strong. After raising these 50 salmon after 5-6 months, their weight can reach 1-2 jin. If the culture density is too dense, it will lead to uneven nutrition of salmon, the occurrence of food grab, there is no guarantee that every fish has adequate nutrition. Therefore, the breeding density should be strictly controlled and fish fry can be released every year in spring and April.

4. Feed

The best feed feeding is domestication of pelletized feed. Roughage must contain nearly half of the protein. If the water temperature is below 8 degrees, it needs to be fed at least twice a day, once in the morning and once in the afternoon. If the water temperature is between 8 and 15, increase the feed at least once a day, once in the morning, in the morning and in the evening, but it is important to note that you only need to make sure that each salmon is full at a time.

5. Water temperature

Most of the salmon are cold water fish, so the water temperature requirements are relatively strict, the most suitable water temperature for salmon growth is 13-15 degrees, but the well water needs to be controlled at 8 degrees. During the breeding period, it is necessary to increase the thermometer in the pool when the temperature is low in spring and winter. Plastic bags can be covered on the scaffolding to heat up the pool water. When the summer temperature is high, well water needs to be changed frequently to lower the pool water temperature.

All right, the above is about the culture technology of salmon. Although salmon mainly grows in the salt water of the sea, it can also adapt to the fresh water environment very well, the only thing that needs special attention is the water temperature, because the suitable water temperature of salmon is relatively low. Too high temperature will make salmon unable to survive, greatly increasing the mortality rate of salmon. For more information, please continue to follow the pro-agricultural network!
