The best culture method of silver carp (how to raise silver carp)
The main results are as follows: 1. The water area of fish stocking is 4 Mu, and the water depth is 5-2m. Appropriate amount of organic fertilizer should be applied to improve the nutrition of water before stocking. It is usually from May to June, avoiding the peak of rotifers. The stocking method generally adopts mixed culture, which can give full play to the utilization rate of water body and the more economical utilization of food. Can breed a little silver carp and carp.
2. Culture ponds: generally speaking, the number of silver carp cultured is relatively large, and special culture ponds will be used. Aquaculture ponds need to be located in sunny places with adequate water sources. The area of the culture pond can be determined according to the number of fish, generally speaking, between 4-8 mu is more appropriate. Water depth: to cultivate silver carp, the water depth needs to be controlled. In spring, summer and autumn, the water depth can be adjusted to 5-2 meters.
3. The first step in breeding silver carp is to build the fish ponds. The fish ponds 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 silver carp raised in my fish pond has been raised for 3 years, but it can only grow up to about 1 to 2 jin and the pond area is 20 to 20.
1, in addition, do not raise silver carp alone, such a deep water level can be appropriate mixed culture of other fish species, so that other fish feed, can play the role of fertilizer and water. Improve economic benefits.
2. The culture cycle of silver carp is generally about 2 years. The first year is mainly fish culture, which takes a certain amount of time to grow. The second year is for adult fish culture, fish fry can grow to about 2 kg-3 kg. During the breeding period, you should change water and feed frequently. Silver carp, also known as silver carp, belongs to the order Cyprinidae, is one of the four famous domestic fish, the four major domestic fish are: herring, grass carp, silver carp, bighead carp. It is a typical filter-feeding fish.
3. Thoroughly clean and disinfect the pond and apply sufficient base fertilizer at one time. Before the fish goes into the pond, it is necessary to dredge the injection and drainage channels and remove too much silt from the pond. When the water depth is 20 cm, each mu of fish ponds will be disinfected with 100 kg of quicklime to kill pests, germs and microorganisms, and then 500 kg of rotten human and animal manure will be used as base fertilizer. Then store water at a depth of 2 to 5 meters and release the fish after a week when the medicine disappears. Increase the stocking specification and put in "two catties of fish".
4. in the aquaculture industry, grass silver carp and bighead carp are usually mixed. Take Henan as an example, the culture density of the four major domestic fish can sometimes reach a very high level, even up to 10,000 jin per mu of ponds. Under normal circumstances, the mixed culture of fish can reach 2000 to 3000 jin per mu of pond. As mentioned above, farming benefits vary greatly depending on region, climate, environment, water quality, as well as farming techniques and inputs.
How to cultivate silver carp
1. Water quality management: silver carp has relatively high requirements for water quality, so it is necessary to keep the water quality of the pond clean and suitable water level. Change the water regularly to maintain the transparency of the water quality and avoid the deterioration of water quality affecting the growth of silver carp. At the same time, we should pay attention to the change of water temperature. Silver carp has relatively strong adaptability to water temperature, but the sharp change of water temperature will still affect its growth.
2. Parent fish culture pond. The area of parent fish culture pond is 2/15-4/15hm2 (2Mu), and the water depth is 5-5m. The location is near the induction pool, the drainage is convenient and the environment is quiet. Clear the pond with quicklime before stocking. Stocking density. About 1500-2250kg per hectare pond. The ratio of male to female is 1:1 or 1:25.
3. Question 10: the food choice of silver carp is similar to that of floral silver carp and silver carp, which mainly feeds on plankton in water. In terms of food preferences, silver carp's preference for vegetarian smell is similar to that of silver carp and silver carp, but also different. Silver carp prefer the mixed smell of sour, sweet and smelly, while silver carp and silver carp prefer the mixed smell of fishy, fragrant and smelly and the mixed smell of sour, sweet and smelly respectively.
4. Fish ponds: disinfect fish ponds before putting silver carp. The fish ponds should be large enough and the culture density should not be too high. Feeding: silver carp can be fed with plankton, or artificially produced micropellet feed. Water quality: in order to ensure the water quality, the water should be changed regularly in the process of breeding. Water temperature: try to keep it above 18 degrees and keep it stable. Don't let the water temperature change dramatically. Disease prevention and treatment: regular disinfection is recommended, and attention should be paid to checking the health status of silver carp.
5. The first step in cultivating silver carp is to build the fish ponds, which should be built in a better environment and away from the bustling and noisy areas such as residential areas and factories. 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.
