High-benefit white-leg shrimp (penaeus vannamei) breeding system and high-benefit white-leg shrimp breeding method

Abstract

The invention discloses a high-benefit white-leg shrimp (penaeus vannamei) breeding system and a high-benefit white-leg shrimp breeding method, wherein the high-benefit white-leg shrimp breeding system is realized by placing culture boxes in an aquaculture pond. The high-benefit white-leg shrimp breeding method comprises the following steps: (1) reorganizing an aquaculture pond; (2) releasing shrimp larvae of white-leg shrimps; (3) regulating and controlling water quality during breeding process; (4) carrying out feed management; (5) carrying out daily management; and (6) preventing shrimp diseases. The high-benefit white-leg shrimp breeding system disclosed by the invention adopts a mixed breeding way of fishes and shrimps in which the fishes are bred by using the culture boxes, so that water quality in the aquaculture pond can be improved with the threat of food battle on the white-leg shrimps eliminated; the culture boxes adopt double-layer designs, so that habitats and shell-changing stopovers can be provided for the white-leg shrimps by peripheral gauze nets; and micro-capsule feeds utilized have improved nutritional values, reduced feed coefficients, good palatability and obvious attractant effects. Thus, the high-benefit white-leg shrimp breeding system and method are capable of raising feeding efficiency, improving aquaculture water, increasing survival rates of the white-leg shrimps and improving taste of the white-leg shrimps, thereby promoting speeding up of industrialization and large-scale cultivation of the white-leg shrimps in local areas.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-efficiency culture system and a culture method of Penaeus vannamei. Background technique [0002] Penaeus vannamei is popular among consumers because of its thin shell and fat body, high meat content, delicious meat, and rich nutrition. Penaeus vannamei has the advantages of strong disease resistance, low salt tolerance, fast growth, and long survival time out of water. It is suitable for large-scale farming in my country. However, outbreaks of prawn epidemics still occur from time to time, threatening the prawn farming industry. In recent years, the survival rate of prawn farming has gradually declined. [0003] Penaeus vannamei is a demersal omnivorous species, and the fish mixed with it should try to avoid competition with it for ecological niches, avoid predation and attack on prawns. In addition, shrimp farming is a high-load farming system, which will cause a do...

Problems solved by technology

In addition, shrimp farming is a high-load farming system, which will cause a double burden on the substrate and water quality during the farming process, which will eventually lead to the deterioration of the farming water environment and cause diseases.

For example, the culture method disclosed in Chinese patent 201310741051.5 "a low-salinity culture method of Penaeus vannamei" is mainly polyculture with sil
