How to raise silver carp will not die easily.

Silver carp, also known as fat head fish, is a kind of fish with a very large head, and its head is much larger than the width of its body. Silver carp grows in various freshwater lakes all the year round. It is a very typical freshwater fish. Although its head is too large, its body shape looks very flat. One deficiency of silver carp is that its tolerance to hypoxia is very poor. Almost as long as hypoxia occurs, it will die after a while. Then the editor will tell you how to raise silver carp so as not to die easily.

I. Culture techniques of silver carp

1. Build fish ponds

First of all, the first step of aquaculture is to build fish ponds, and the land for fish ponds should be built in places with better environment, and then the area of fish ponds should be determined according to the culture density and number of farmers. It is best to build a larger one. A farmer can cover 4-8 mu of fish ponds. If friends who have culture experience and technology can raise as much as possible, they can maximize profits at one time. The depth of the fish pond should be at least two meters, and the bottom should be covered with rotten livestock manure, urine fertilizer or other organic fertilizer, which can only be used after dilution.

2. Stocking fish fry

After the fish pond is built, fish fry can be released next, and there are two ways to release fish fry, which are monoculture and mixed culture, which means to raise them together with other species of fish in writing. This can keep the whole ecosystem in the fish pond in balance and enable all kinds of fish to grow smoothly. If used in this way, the profit can be very high, in addition, monoculture. Monoculture is the direct investment of seedlings, do not need to be mixed with other seedlings, according to the general process on it, very simple.

3. Daily management

Silver carp, a big-headed fish, usually uses plankton as the main source of food when it grows in the natural environment, so it is the same in fish ponds. We should change water frequently in the process of culture and keep the water quality clean and sanitary. We can also artificially produce some edible aquatic plankton in the water. In addition, the feed should be fed regularly, and the feed should be diversified. Do not be too simple, can be replaced every once in a while, this is the best, for nutritional needs can be met.

4. Overwintering management

When the temperature is about to enter the winter, the temperature drops very fast, and the lower the temperature is, the lower the activity frequency of silver carp will be, especially when the temperature is below 10 degrees, the physical activity of silver carp will become very poor and will hardly eat any more. so we should try to raise all the fish together and increase the culture density, which will be much better. At this time, we should put them on the market as soon as possible. Wait until the next year to raise new seedlings.

2. Anoxia of silver carp

At the beginning of the construction of the pond, it is necessary to do a good job in the fertility of the water and increase the dissolved oxygen content in the soil, and another is that the fertility in the fish pond must be adequate, and in addition, the number of aerators in the fish pond should be sufficient, which is very important. It is most important to ensure that the oxygen content in the water is sufficient, and the sufficient oxygen content in the water can greatly reduce the mortality of silver carp.

The above is how to raise silver carp will not die easily, silver carp breeding is also a relatively risky job, this kind of fish oxygen tolerance is too poor, as long as a little lack of oxygen supply, there will be the risk of death.
