Efficient and healthy culture method of shrimps

Abstract

The invention belongs to the technical field of shrimp culture, and particularly relates to an efficient and healthy culture method of shrimps. The method includes the steps: S1, performing comprehensive treatment of the water quality of a water source; S2, adding fertilizer; S3, putting shrimp seeds; S4, regulating the culture water environment; S5, adding feed; S6, adding an oxidant for bottom change; and S7, taking the shrimps out of a pond for sale. The cultured shrimps have a large size, a high survival rate and high disease resistance, and the economic benefits of shrimp culture are improved greatly. According to the method, microorganisms are utilized to adjust the water quality, no chemicals are added in the culture process, material feeding and water change are reduced, the problem of chemical residues of the shrimp products can be solved from the source, and pollution of culture wastewater to the environment is reduced due to no chemical residues; and meanwhile, tail water istreated biologically, then water discharge is performed, and therefore, the method is an efficient, environment-friendly and healthy method for cultivating shrimps, and has broad market development prospects.

Description

technical field [0001] The invention belongs to the technical field of prawn cultivation, and in particular relates to an efficient and healthy cultivation method of prawns. Background technique [0002] Prawns belong to the genus Penaeidae of the order Decapod Crustacea. It is delicious and nutritious, and is loved by consumers in my country. The growing demand has made the shrimp aquaculture industry a pillar industry in my country's mariculture industry. However, problems such as disease control, drug residues, shrimp product quality, and aquaculture environmental pollution in shrimp aquaculture have always affected the healthy and stable development of the shrimp aquaculture industry. [0003] At present, there are mainly three types of shrimp farming in my country, namely, high-density intensive culture in high-level ponds, intensive or semi-intensive extensive culture in low-density earthen ponds, and low-density extensive culture in dams. Among them, high-density int...

AI Technical Summary

Problems solved by technology

Among them, high-density intensive cultivation in high-level ponds requires the use of water purifiers and ecological preparations to control water quality, and the use of antibiotics to prevent and control diseases, resulting in drug residues, which pollute the environment and make it difficult to ensure the quality and safety of prawns. Although the aquaculture output is high, the aquaculture survives. The rate is low, the risk is high, and the product size is generally small (above 60 tails / kg); intensive or semi-intensive and extensive cultivation in low-density earthen ponds, due to poor control conditions, cannot discharge sewage, and also need to use a large amount of water purifiers and ecological preparations Regulating water quality and a large amount of antibiotics to prevent and control diseases have the problem of drug residues. Although the product specifications are generally large (more than 50 tails / kg), the output is low, the production cost is high, and the economic benefit is poor; Adopt natural breeding, self-drainage and self-irrigation, feeding seedlings without feeding, although the product size is generally large (more than 40 tails / kg), but the output is very low, the survival rate is low, and the economic benefit is poor

[0004] It can be seen that the current shrimp farming methods generally have problems such as drug residues, low survival rate, and poor economic benefits.

In response to the above problems, Chinese patent application CN103404458A discloses a method for biological control and cultivation of large-scale prawns. Pond water quality environment and disease biological control, feed feeding and other steps, using the biological control method of beneficial bacteria and beneficial algae, the obtained prawns are large in size, good in quality, high in yield, good in breeding benefits, and at the same time avoid antibiotic drug residues It has a good market development prospect, but it mainly focuses on micro-ecological preparations and water quality improvement of aquaculture ponds, but ignores the bottom conditions of aquaculture ponds, and a large amount of nutrients and biological excrement will settle in the ponds. If there is too much organic matter at the bottom of the pond, it will cause the deterioration of the bottom and affect the survival rate of prawns. Moreover, the untreated tail water will easily cause environmental pollution.
