Embodiment 1

[0039] Embodiment 1 simulation experiment of growing algae

[0040] This embodiment selects temperature, illumination, pH, N / P (nitrogen-phosphorus ratio), Fe 3+ The five influencing factors of concentration were taken as the research objects, and the culture process was optimized by using the orthogonal experiment design, and the best culture conditions were obtained, which provided a theoretical reference for the algae cultivation process of shrimp culture in high-level ponds.

[0041] The algal species were taken from the prawn farm in Zhaoan County, mainly Chlorella, using BG11 medium, and the initial algae density was adjusted to 1.3×10 in a 2000mL Erlenmeyer flask. 6 ind·mL or so, placed in a light incubator for cultivation.

[0042] Five gradients are set for each impact factor, among which 15, 20, 25, 30, and 35°C are selected in combination with the temperature range in Fujian. Light intensity: 3000, 4000, 5000, 6000, 7000Lx. pH: 6.5, 7.0, 7.5, 8.0, 8.5. Based on ...

Embodiment 2

[0051] Embodiment 2 Shrimp culture high level pond

[0052] Please refer to the attached figure 1 to attach Figure 11 , in the present embodiment, a kind of elevated pond for cultivating prawns comprises at least two elevated pond monomers 1 and a drainage well 2, the elevated pond monomer 1 includes a square rounded corner pond body 11, and the square rounded corner pond body 11 is provided with Aeration device 12, and through the aeration device 12, the water body in the square rounded pool body 11 can form a directional vortex to collect the waste at the bottom of the pool to the center of the pool body, and a funnel is provided at the bottom center of the square rounded corner pool body 11 Shaped sieve plate 13, the side wall of funnel-shaped sieve plate 13 is provided with a plurality of filter holes 131 for sewage and drainage, and an opening 132 is provided at the bottom of funnel-shaped sieve plate 13, and an opening 132 that can block the opening 132 is movably conn...

Embodiment 3

[0069] Adopt the high-level pond for culturing prawns in Example 2, before putting seedlings, get 1 high-level pond monomer (1) to grow algae, and fill the algae water after it into all high-level pond monomers (1) as Put the culture water of the seedling stage, and then put the seedling culture.

[0070] Specifically, the conditions for growing algae are temperature 25°C, light 7000Lx, pH 8.5, N / P 10:1, iron ion concentration 500μg·L -1 .

[0071] After the cultivated high-quality algae water is introduced into the shrimp pond, the algae in the pond can absorb the nitrogen and phosphorus produced during the cultivation process, keep the water body stable, and help farmers to better survive the seedling period. However, there are still risks in breeding, and the water quality in the breeding process needs to be monitored to better control the water quality. Considering that the individual farmers who dominate the culture lack the conditions and ability to test the water qual...

Abstract

The invention relates to a prawn aquaculture method. According to the method, prawn aquaculture higher-place ponds are designed, one higher-place pond monomer (1) is taken to culture algae before young prawns are released, all higher-place pond monomers (1) are filled with cultured algae water to serve as aquaculture water at a releasing stage of the young prawns, and the young prawns are releasedto culture the prawns. According to the prawn aquaculture method, high-quality algae water is cultured by the higher-place pond monomers, the method helps a farmer to spend difficult releasing stageof the young prawns, aquaculture risks are reduced, and aquaculture incomes are improved.

Description

technical field [0001] The invention relates to culture techniques, in particular to a method for cultivating prawns. Background technique [0002] In the process of shrimp farming, the quality of the water body determines the success or failure of the culture, especially in the stage of releasing seedlings in the early stage of the culture, the shrimp seedlings have poor resistance and have higher requirements on the water body. However, there is a misunderstanding in the existing culture, and it is believed that the bottom of the pond where the algae water is released will produce mud skin and it will be difficult to manage in the later stage. However, when seedlings are placed in clear water, there are few plankton in the water body, and the natural biological bait required by prawns is lacking, which increases the cost of breeding. At the same time, the transparency of the water body is high, and the larvae are prone to stress reactions. Moss is easy to grow on the pool...
