How to raise the mackerel, which is known as the giant panda in the water?

Last time we talked about Sturgeon, this time we talk about mackerel. The bream is also a kind of Sturgeon, which is larger than the Sturgeon. The bream is known as the giant panda in the water. Moreover, the herring meat is delicious and has no fish bones, so it is very popular with fish lovers. So how should the mackerel be cultured? Let's take a look at it.

I. selection of Culture Environment

The size of the mackerel is very large, so when cultured, the fish pond must be large and the water level should be very deep. Generally, the water level should be kept at 2-3 meters, and the water quality should be clear and pollution-free. The dissolved oxygen in the water body should be controlled at about 5 mg per liter, and in the process of culture, an aerator should be prepared to ensure sufficient dissolution of the water body and avoid death caused by hypoxia, and it is also necessary to set up a feeding table to facilitate feeding.

2. Disinfection

The first thing to do before breeding is to clear the pond and disinfect the clear soup for about 10-20 days before releasing seedlings and breeding. The disinfection of the pond should first reduce the water depth to about 70 cm, and then sprinkle the lime mixed water comprehensively, which can eliminate the harmful microorganisms in the pond. After 3 to 4 days of disinfection, all the water in the pond will be discharged, and then the water will be fed again and disinfected with tea cakes. The remaining tea bran can be used as fertilizer and disinfected with chlorine-containing disinfectant half a month before seedling release. Only after such full disinfection can the seedlings be released with peace of mind.

3. Seedling release test

The first thing to do before releasing the fry is to choose the fry that are healthy, energetic and have a large appetite, with a body length of more than 20 centimeters, and the overall size of the fry should not exceed 5 centimeters, so as to facilitate later feeding management. The time when we release seedlings is very important, not only to consider the water temperature, but also to consider the time of listing. Before releasing the fry, put the fry into a container containing water, then inflate it continuously, and add salt to the container, so that the salt concentration of the water in the container reaches about 3%. Soaking for 10-20 minutes, then releasing the fry can greatly improve the survival rate and kill the pathogenic microorganisms carried on the surface of the fry to reduce the occurrence of disease.

Fourth, feeding

When the fry is just put into the pond, there is no fixed feeding point, so it needs to be domesticated first, and the feed can be put on the feed table first, so that a fixed feeding point can be formed and the feed utilization rate can be improved. When feeding, we must adhere to the principle of feeding a small amount and more, and the feed should also conform to the palatability of the fish. Usually, the size of the feed particles can reach the size of the fish mouth is usually the best. And the feeding amount is 3% of the total weight of the fish, which needs to be fed about four times a day, and the feeding amount can be adjusted according to time.

The above is proudly brought to you the mackerel culture technology, I hope you can learn, if you do not understand anything can leave a message in the comments area, I will answer for you in time.
