Embodiment 1

[0019] A method for cultivating high-quality vannamei in freshwater, comprising the following steps:

[0020] (1) Management of aquaculture ponds: Each 5-acre pond is equipped with 3 sets of 3KW impeller-type aerators. After disinfection, exposure to the sun, and clearing of the ponds, the injected water is filtered with a double-layer 80-mesh polyethylene net to maintain a water depth of 0.8-1m. Adjust the PH value of the breeding water to 7.6-8.6, and adjust the water quality by 1.5-2kg of microbial preparation per mu 5-8 days before the shrimp seedlings go to the pond, and a temperature adjustment device is installed at the bottom of the pond;

[0021] (2) Shrimp stocking: start stocking when the water temperature reaches 20°C, stock 8,000-10,000 larvae with a length of 1-1.5cm per mu, mix with 500 river crabs of 120-150g, 200 silver carp of 100g, 100g 50 silver carp;

[0022] (3) Breeding management:

[0023] a. Condition management: According to the different growth con...

Abstract

The invention discloses a method for freshwater aquaculture of high-quality penaeus vannamei boone. The method comprises the steps of aquaculture pond management, young shrimp breeding, aquaculture management and common disease prevention and treatment. Compared with the prior art, the method has the advantages that due to scientific and reasonable design of growth conditions of stages of penaeus vannamei boone, river crabs, silver carp and spotted silver carp are matched, diseased and dead penaeus vannamei boone can be removed in time, pathogeny spread is effectively avoided, the water quality is adjusted and improved, meanwhile, bait can be sufficiently utilized, no disease exists in the culture process, the aquaculture survival rate reaches 78% or above, the specification of the penaeus vannamei boone is 52-58 / kilometer, the quality is good, the penaeus vannamei boone body is semitransparent and glossy, muscular tissue is arranged compactly and elastically, and the economic value for cultivating the penaeus vannamei boone is improved from multiple aspects.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a method for cultivating high-quality Penaeus vannamei in fresh water. Background technique [0002] Penaeus vannamei has delicious meat, high meat yield, fast growth, and strong disease resistance. It is currently the largest shrimp farming species in my country. Most parts of China, both in the south and in the north, are breeding Penaeus vannamei, but due to its management Poor, although a lot of money has been invested, the success rate of breeding has not been greatly improved, and because most of the vannamei culture is cultured under natural conditions, it cannot absorb protein and other organic matter better during the growth process. The low quality of Penaeus vannamei is caused by the low survival rate and poor quality problems, which cause a lot of economic losses for shrimp farmers. In order to improve this situation, it is necessary to stud...
