Embodiment 1

[0042] Such as figure 1 As shown, the culture pond, the water circulation treatment pond, the biological purification pond and the water storage pond form a water circulation system, and the volume ratio between the four is 5:1:3:1, and multiple culture ponds are connected to this water circulation system in parallel In , the circulation process of aquaculture water is as follows:

[0043] (1) The aquaculture sewage is discharged from the aquaculture pond, enters the water circulation treatment pond to remove suspended solids such as residual bait and feces in the water body, and after ozone sterilization and degradation treatment, it is discharged into the biological purification pond;

[0044] (2) The water body is in the biological purification tank, after biological filtration treatment, the ammonia nitrogen, nitrate, nitrite and other organic substances in the water are removed, and the carbon dioxide and other gases that are not conducive to breeding are removed through ...

Embodiment 2

[0047] Such as figure 2 As shown, the breeding pond 1 adopts a cylindrical design with a diameter of 2.0m, a pond depth of 1.5-2.0m, an effective water depth of 1.3-1.8m, a V-shaped structure with a 2-5% slope at the bottom of the pond, and a sewage outlet 2 at the bottom. , such a design ensures that the water in the pool can be drained by itself; the breeding pond 1 is provided with a sewage pipe 3, which communicates with the sewage outlet 2, and the sewage outlet 2 is further connected to the water circulation treatment pool. The bayonet is fixed so as to be set on the periphery of the sewage pipe 3, and the pipe walls of the sewage pipe 3 and the sewage outer pipe 4 are provided with small holes 5 with a diameter of 0.5 cm, and the sewage pipe 3 is wrapped by a sieve silk mesh cloth, and the sieve silk cloth The mesh of the mesh is selected according to the size of the shrimp body to prevent the cultured Penaeus monodon in the culture pond 1 from entering the sewage pipe...

Embodiment 3

[0052] Specific methods for farming P. monodon using recirculating aquaculture systems include:

[0053] (1) Water quality treatment before putting seedlings

[0054] Before putting in shrimp seedlings, add filtered pool water to the culture pond, use algae nutrient dew to adjust the pool water to light brown, and then inoculate the pool water with probiotics: including bacillus, lactic acid bacteria and photosynthetic bacteria, the inoculation concentration is spore Bacillus 1×10 9 ~1×10 10 CFU / L, lactic acid bacteria 1×10 9 ~5×10 9 CFU / L, photosynthetic bacteria 5×10 9 ~1×10 10 CFU / L; the water quality conditions of the pool water are adjusted as water temperature 28-30°C, daily temperature difference ≤2°C; salinity 25-30, daily salt difference 2-5‰; pH value 7.9-8.7, ammonia nitrogen content ≤2.0mg / L , dissolved oxygen content ≥ 5.0mg / L.

[0055] (2) Shrimp seed feeding

[0056] Select healthy and healthy Penaeus monodon shrimp seedlings with a size of 1.2-1.5cm, di...

Abstract

The invention discloses an indoor multilayer three-dimensional circulating aquaculture system for penaeus monodon. The system is characterized in that a culture pond, a water circulating treatment pond, a biological purification pond and a water storage pond communicate to form a circulating water path; the water circulating treatment pond is provided with a water treatment mechanism for purifying water, the biological purification pond is provided with a biological filtration mechanism for further purifying water, and the water storage pond is provided with a water body adjusting mechanism for adjusting water body parameters; and plurality of layers of culture planes formed by bolting silk mesh cloth are arranged in the culture pond, a plurality of culture planes which are arranged at intervals are contained in the same layer, and the front ends of the culture planes incline downwards, so that a plurality of culture water layers are formed in the culture pond. The system has the characteristics of being flexible, capable of fully utilizing culture water, low in operation cost, energy-saving and environmentally friendly, and can effectively increase the habitat and culture area of the penaeus monodon and increase the culture yield. The invention further discloses an aquaculture method using the aquaculture system.

Description

technical field [0001] The invention belongs to the technical field of marine product artificial cultivation, and in particular relates to an indoor multi-layer three-dimensional circulating aquaculture system and a cultivation method of Penaeus monodon. Background technique [0002] Penaeus monodon aquaculture has always been a traditional aquaculture project in my country. In recent years, affected by the deteriorating water quality of the aquaculture waters, the cultured Penaeus monodon disease frequently occurs. The shrimp farming industry in most areas is in the "intensive culture" mode affected by diseases, while the "extensive culture" mode is affected by the continuous urbanization and industrialization. Advancing and decreasing land resources are facing the situation that no resources are available. The safety of Penaeus monodon has attracted increasing attention due to the deterioration of the breeding environment and water quality. For the sustainable development...
