How to raise silver carp

Silver carp is what we call fat-headed fish in our market life, because it is similar to silver carp in shape, with many patterns on the body and a big and round head, so it is called silver carp. Silver carp is a typical freshwater fish, which is very common in major freshwater lakes. It is very suitable for artificial breeding and is the most common species of artificial breeding. However, the hypoxia tolerance of silver carp is very poor, a little hypoxia will lead to death, then how to cultivate silver carp? Let's take a look at it.

1. Set up fish ponds

The first step in breeding silver carp is to build the fish ponds, which should be built in a better environment, away from residential areas, factories and other busy and noisy areas. The area of fish ponds is determined according to their own culture density and area, but it is best to be as large as possible. now most of the fish ponds of each grower are between 4-8 mu, and experienced friends can raise more according to their own conditions. raise your own economic interests to the highest. The water depth of the fish pond shall not be less than two meters. Laying organic fertilizer on the bottom of the pond can effectively provide nutrition for silver carp and promote the growth of silver carp.

2. Stocking fish fry

After the establishment of the fish pond, the next step is to release fish fry, which is divided into monoculture and mixed culture, which is the comprehensive culture of silver carp and other species of fish. The advantage of this kind of mixed culture is that it can keep the ecosystem in the fish pond in a balanced state, so that all kinds of mixed fish can grow and develop smoothly. Mixed culture can not only make money for the benefits of silver carp culture, but also make money for the economy of other species, so that the economic benefits of fish culture can be maximized. According to the literal meaning of monoculture, only one kind of silver carp fish is cultured alone, and the economic benefit of this kind of fish is not as high as that of mixed culture, so now it is basically mixed culture.

3. Daily management

Wild silver carp mainly feed on zooplankton on the water surface in the natural environment, so in artificial culture, silver carp will also feed on zooplankton in fish ponds. However, this is actually disadvantageous to the growth of silver carp, so the water must be changed frequently in the process of culture to keep the water clean and hygienic. Can also be used to make some edible zooplankton in the water for silver carp to eat, and at ordinary times when artificial feeding must be timed, the feed should be diversified as far as possible, do not use too single feed, and change the feed once in a while, it can effectively meet the nutritional needs of silver carp.

4. Overwintering management

How to survive the winter and ensure the survival rate of silver carp after overwintering is a problem that many farmers need to pay attention to. Because at the beginning of winter and after the beginning of winter, the temperature drops very fast. The lower the temperature, the lower the frequency of silver carp activity. If the temperature drops to 10 degrees, the physical activity of silver carp will begin to get worse and worse, or even lose its activity. Eat very little or no more food, so try to gather the fish together during the overwintering, increase the farming area, make the temperature less cold, or put it on the market before winter, and then rebreed the new seedlings the following year.

The above is the introduction of silver carp culture methods. Silver carp is a kind of fish that is extremely intolerant to hypoxia, so when breeding, try to prepare an oxygenation equipment next to the pond. To prevent the sudden occurrence of hypoxia in the fish pond, so that oxygen can be added to the fish pond in time to ensure the survival rate of silver carp. If there is a slight lack of oxygen in the pond, it will make it difficult for silver carp to breathe and die within a few hours.
