secondly, natural enemies in the nature are too much, and mice, snakes and the like can seriously threaten the survival of the aquatic animals;

thirdly, in the process of hatching the aquatic animals, the newly born larvae are easily eaten by the parents or by natural enemies, so that the survival rate of the seedlings is low;

fourthly, the residual baits and feces cannot be cleaned in time, and are easy to decay and deteriorate, so that the water quality is damaged, and the aquatic animals die greatly;

fifthly, a plurality of aquatic animals need to be covered with sheds in winter, the water area is limited, large-density culture cannot be carried out, the aquatic animals are spread out, and the cost of covering the sheds is high;

due to the influence of the factors, the yield per mu is low, the culture cost is high, the culture condition in water is difficult to observe, and some accurate data such as survival rate, distribution and the like cannot be obtained;

and seventhly, in the resource-scarce times, when large-scale and large-area cultivation is needed, land resources meeting large-scale cultivation and rich water sources are difficult to find.

Eighthly, close-relative propagation cannot be effectively avoided, so that the quality of seedlings is reduced year by year, and the seedlings are not cultivated greatly.

In conclusion, the existing aquaculture mode has low utilization rate of water body space, low aquaculture density, low survival rate of aquatic animals and higher cost.

Especially compared with the three-dimensional aquaculture on land, the cost can be reduced by about one fifth.

Capital investment, breeding density and survival rate vary from aquatic animal to aquatic animal, exemplified herein by breeding of australian crayfish:

1. in the common culture method, 5000-6000 seedlings are thrown in each mu of pond, and the survival rate is about 50%; by adopting the water body three-dimensional culture system, more than 10 thousands of seedlings can be thrown per mu of pond, which is about a dozen times to twenty times of the common culture method; the survival rate can reach more than 90 percent.

2. In the common culture method, in order to avoid eating shrimps by the shrimps, ponds need to be cleaned every year (water is pumped out, the shrimps and other things are cleaned, and then the ponds are sterilized and dried), so that time and labor are wasted. By adopting the water body three-dimensional culture system, the shrimps can be cultured circularly without cleaning the pond every year, the situation that the shrimps eat the shrimps when the shrimps and the shrimps are cultured in the same pond is not considered, and time and labor are saved.

3. By adopting the water body three-dimensional culture system, although the investment of the first investment is larger than that of the common culture, the overall investment is smaller than that of the common culture in contrast with the long-term cost. Taking the service life of a cultivation mesh box as an example of at least 10 years, adopting the cultivation method, selecting 10 layers of multi-layer isolation mesh boxes (hereinafter referred to as mesh boxes for short) with 80 independent spaces, the length of 0.56 meter and the width of 0.42 meter, reserving an operation space of 0.48 meter between every two rows of mesh boxes, obtaining that the space area required by each mesh box is 0.56 x 0.9 square meter, more than 12000 net cages can be placed in 10 mu of pond, each net cage can be used for cultivating 80 shrimps, 100 million shrimps can be cultivated in 10 mu of pond, and 480 million mesh boxes with 10 layers are required to be put into each 400 yuan of market price; the investment of foundation construction (pond foundation cloth pipelines, winter shed covering and the like) is about 80 ten thousand; the pond renting is calculated according to 2000 yuan per mu per year in the coastal areas of Guangdong, and 20 ten thousand is needed for 10-mu annual rent; the total investment in infrastructure is about 600 million.

To sum up: the method is calculated according to the data that the shrimp seeds can be cultivated in two seasons per year, 100 thousands of shrimp seeds can be cultivated in each season, the survival rate is 80%, the average amount of 0.5 yuan of shrimp seeds per finished product shrimp (1 CM long) is 50 grams per shrimp, and the average amount of 50 yuan per 500 grams of finished product shrimp (the annual pond head purchase price is about 50-60 yuan), about 600 thousands of total investment can be used for building an aquaculture factory with the annual output value of 800 thousands, the cost can be recovered from one year to half a year, the operation cost, the cost of the shrimp seeds and the cost of the feed are only deducted in each year, and the pure profit can reach more than 60-70%.

By adopting a common breeding method, the basic investment and economic value are compared as follows:

100 million shrimps are cultured, calculated according to 5000 shrimps per mu, 200 mu of pond is needed, and 400 million shrimps are rented in the pond in 10 years; covering a winter shed for 200 mu of pond, and calculating according to the average artificial material addition of 2000 yuan/mu/year, wherein the quantity is 40 ten thousand per year and 400 ten thousand per 10 years; the pond cleaning is calculated according to 300 yuan per mu (labor and electricity charge) per year, 200 mu requires 6 ten thousand per year, and 60 ten thousand per 10 years; the infrastructure cost of 10 years light reaches 860 thousands, and the investment exceeds the cultivation mode of the water body three-dimensional cultivation system. The survival rate is calculated according to 50 percent, the cost of dead shrimps and feed is also deducted, and the annual income is only 50 percent of that of a water three-dimensional culture system (equipment).

4. In the aspect of hatching the shrimp larvae, the water body three-dimensional culture system saves a large amount of funds compared with the common method. The basic construction of the shrimp larva hatching factory is a large area, and the shrimp larva is hatched by adopting the culture method, so that the plane space can be changed into a three-dimensional space, and the cost of the basic construction is effectively shared.

5. The water body three-dimensional culture system can be used for culture or incubation, and the problem of land resource shortage of aquaculture is solved greatly.

When the aquatic animals are bred to be delivered, the whole multi-layer isolation mesh box 1 can be taken out of the pond, water in the multi-layer isolation mesh box is completely discharged in the taking-out process, and then the baffle is opened, so that the aquatic animals in each isolation space 1 can be taken out.

In some embodiments, the water three-dimensional culture system can be used for raising seedlings besides aquaculture. For this purpose, the bottom surface of each insulation space 1, which is not the bottom layer of at least one multi-layer insulation mesh box 1, may be provided with a plurality of separation holes, so that the seedlings produced by the aquatic animals in the insulation space can enter the next layer through the separation holes, thereby realizing the separation of the adult aquatic animals from their seedlings. The size of the separation pores is determined by the aquatic animal being cultivated and needs to be larger than the size of its young seedling but smaller than the size of an adult aquatic animal so that only young seedlings can pass through. During specific application, can put into two aquatic livestock in every isolation space, and a public mother, the back is mated to the two, and the seedling of production can get into the vacant isolation space of next layer through the separation hole of bottom surface in, realizes the separation to this avoids adult aquatic livestock to kill, preys its seedling, avoids consequently producing the loss.

As mentioned above, the water body three-dimensional culture system is mainly divided into three blocks, namely a first isolation mesh box and a multilayer isolation mesh box, wherein the multiple layers are optional; secondly, a water flow feeding system; and thirdly, a sewage recycling system for residual bait, aquatic animal manure and other sewage.
