Background

The Chinese prawn farming industry faces serious problems of sustainable development in recent years. The diseases in some areas are serious and have a spreading tendency; the growth of the prawns is delayed in some time in some regions, which leads to the failure of the culture and even the loss of the cost.

At present, the traditional domestic breeding usually adopts 6 modes, including:

1) a soil pond coarse culture mode;

2) an earth pond culture mode;

3) a semi-refined pond culture mode;

4) a segmented high pond intensive culture mode;

5) a fish and shrimp polyculture mode;

6) and (3) an industrial high-level pond culture mode.

The above 6 modes have high yield in the sectional high-level pond intensive culture and industrial culture modes, but the traditional methods of the two culture modes have very high requirements from feeding to water quality management, and the problems of water and soil resource waste, water pollution, environmental pollution, high drug dosage caused by diseases, high culture cost and the like exist at present.

Based on the management regulations of sustainable development of aquaculture, environmental protection, food safety and the like in China, more advanced and innovative culture modes and culture technologies which accord with the future development of China are needed.

In the prior art, the multi-layered culture system is similar to the utility model in Taiwan patent. The patent technology is based on the high-density cultivation system of U.S. Pat. nos. 4368691, 4446025 and 5961831, and the main problem in the above patent is that the rearing rate is increased due to the increase of the cultivation density, and the yield is reduced. To solve this problem, a technique for effectively managing behavior of aquatic crustaceans at a high culture density is proposed. Mainly utilizes the tendency of aquatic crustacean to contrast light and dark light to design a method and a device for managing the movement or positioning of aquatic crustacean. As shown in FIG. 1, the multi-layered aquaculture system mainly comprises a plurality of containers (aquaculture tanks) 1 for holding aquaculture water, a device for showing contrast effect in a specific area in a single container or each container, a device for draining sewage, and a water treatment integrated device.

In addition, the prior art is similar to the utility model in the novel patent of taiwan of china, "three-section type cavitation super intensive shrimp culture system". The three-section cavitation super-intensive shrimp culture system is characterized in that small shrimps, medium shrimps and large shrimps are divided into three culture areas, each culture area is provided with a culture groove 1, a sewage reservoir 23, a cavitation separator 2 and a biochemical water filtering pond 25, so that shrimp farmers can harvest the large shrimps in a short time interval, the harvest period is increased, and the shrimp groups are moved to the pond and the pond is cleaned during the harvest period.

However, the multi-layered culture system utilizes the property of light-shielding survival of aquatic crustaceans, and necessarily needs to apply some artificial light sources, while the growth speed of the aquatic crustaceans is reduced under the influence of light, so that the foraging activity is reduced, and the introduction of the light sources adversely affects the natural nature of weak light. In addition, in the above-mentioned "multi-layered aquaculture system", the design of the shallow water tank and the water flow device is liable to cause insufficient oxygen in water, and even if an oxygen supply device is added, oxygen is not dissolved in water and is volatilized, which is not favorable for the growth of aquatic crustaceans.

The main disadvantage of the above-mentioned three-stage cavitation super-intensive shrimp culture system is that the shrimp body is partitioned based on the traditional culture, during the harvest period, the shrimp group moving pool and pool cleaning work still needs to be performed, the sewage treatment efficiency is low, the sewage reservoir 23 and the biochemical water filtering pool 25 must be separately arranged in each culture area, and the working efficiency is low while the space is occupied.
