Problems solved by technology

Penaeus vannamei is widely cultured. Regardless of whether it is industrialized or high-level ponds, the cost of each facility is high, the area is large, the success rate is low, and the output is low. It is not suitable for small and medium-sized rural farmers. With the growing area of ​​breeding, a large amount of breeding wastewater Discharge, leading to frequent occurrence of diseases, low breeding success rate, difficult to increase production, seriously hindering the healthy development of shrimp farming industry
[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Embodiment 1

[0017] The standard construction of the seedling pool is generally 35 meters in size, 10 meters in width, and the roof height is not more than 3 meters. If it is too high, the performance of resisting strong winds is poor. Due to feeding and medication operations, cement floors are used as aisles in the middle of the greenhouse. There are two doors at the front and back of the greenhouse, the door is 1.5 meters long and 0.9 meters wide, which is convenient for pedestrians to enter and exit.

[0018] The aquaculture water source mainly comes from deep-water wells. The depth of deep-water wells is generally 30 meters. In addition to the depth of the well, there is also the choice of the area.) The well water is less polluted and rich in various mineral elements. The indicators of the well water are relatively normal, which is conducive to the cultivation of shrimp. Mitigation of toxicity plays an important role.

Embodiment 2

[0024] The standard construction of the seedling pool is generally 60 meters in size, 15 meters in width, and the height of the roof is not more than 3 meters. If it is too high, the performance against strong winds is poor. Due to feeding and medication operations, cement floors are used in the middle of the greenhouse as aisles. There are two doors at the front and back of the greenhouse, the door is 1.5 meters long and 0.9 meters wide, which is convenient for pedestrians to enter and exit.

[0025] The aquaculture water source mainly comes from deep-water wells. The depth of deep-water wells is generally 50 meters. In addition to the depth of the well, there is also the choice of the area) the well water is less polluted and rich in various mineral elements. The indicators of the well water are relatively normal, which is conducive to the cultivation of shrimp. Deep water wells can alleviate the toxicity of nitrite in the middle and late stages has an important role.

Abstract

The invention relates to a method for breeding penaeus vannamei in a greenhouse and belongs to the technical field of aquaculture. The method specifically comprises the six steps of 1, seedling pond specification construction; 2, water source preparation; 3, water circulation treatment; 4, oxygenation; 5, heat supply; 6, increase of the utilization rate of baits by shrimps. According to the method, external pathogens, bacteria and other microorganisms are isolated through heat preservation of the greenhouse, and the method has the advantages that in the whole breeding process, the influence of weather changes on the shrimps in the greenhouse is small, the controllability is high, and the facility degree is high. The greenhouse is of a complete steel frame structure and is safe, reliable and high in stability, and a cement floor is adopted as an aisle in the middle to provide convenience for pedestrians to put feed and observe the physical symptoms and feeding conditions of the shrimps. The method for breeding penaeus vannamei in the greenhouse has the advantages of no limitation of seasons, high density and high feeding rate, and is relatively stable and favorable for the growth and inspection of penaeus vannamei and monitoring and regulation of water quality indexes.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a method for cultivating Penaeus vannamei in a greenhouse. Background technique [0002] Penaeus vannamei is also known as white-limbed shrimp, white prawns, and prawns. Penaeus vannamei is native to the waters of the Pacific coast of South America and is one of the three largest shrimp species with the highest aquaculture production in the world today. In terms of breeding, Penaeus vannamei has the characteristics of large individual, fast growth, low nutritional requirements, strong disease resistance, strong adaptability to changes in water environment factors, low requirements for feed protein content, and a meat yield of over 65%. , is an excellent variety for intensive high-yield farming. Penaeus vannamei is widely cultured. Regardless of whether it is industrialized or high-level ponds, the cost of each facility is high, the area is large, the success rate is low, and...
