Three-dimensional water culture system

Abstract

The invention discloses a three-dimensional water culture system. The three-dimensional water culture system comprises one or more multi-layer isolation mesh boxes and a water flow feeding system; thewater flow feeding system is used for delivering baits into the multi-layer isolation mesh boxes; the multi-layer isolation mesh box has multiple layers; each layer comprises multiple isolation spaces; the isolation spaces are used for culturing aquatic animals; the water flow feeding system comprises delivery pipes; each multi-layer isolation mesh box is vertically penetrated by one or more delivery pipes; each isolation space of each multi-layer isolation mesh box is communicated with a delivery pipe; and, when a pressurized water flow containing baits is input into the delivery pipe, the baits in the pressurized water flow enter the communicated isolation space through a ventilation hole formed in the delivery pipe. According to the three-dimensional water culture system in the invention, the multi-layer isolation mesh boxes are adopted; furthermore, the aquatic animals are isolated by utilization of the isolation spaces; therefore, the utilization rate of water spaces is increased; the culture density and the survival rate of the aquatic animals can be greatly increased; furthermore, the cost is relatively low; and thus, the three-dimensional water culture system in the invention has relatively high economic benefit.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a three-dimensional water body cultivation system. Background technique [0002] Traditional aquaculture generally uses ponds for stocking. Practice has found that there are some disadvantages as follows: [0003] 1. There are some aggressive aquatic animals that often fight and cannibalize each other, which seriously affects the yield. For example, lobsters and crabs are all aggressive aquatic animals. They are vulnerable to damage during the shelling process. attack, resulting in death; [0004] 2. There are many natural enemies in nature, such as rats and snakes, will pose a serious threat to the survival of these aquatic animals; [0005] 3. During the hatching process of these aquatic animals, the newly born larvae are easily eaten by the mother or natural enemies, resulting in a low survival rate of the seedlings; [0006] 4. There is no way to clean up the leftover ...

AI Technical Summary

Problems solved by technology

[0003] 1. There are some aggressive aquatic animals that often fight and cannibalize each other, which seriously affects the yield. For example, lobsters and crabs are all aggressive aquatic animals. They are vulnerable to damage during the shelling process. attack, resulting in death;

[0004] 2. There are many natural enemies in nature, such as rats and snakes, will pose a serious threat to the survival of these aquatic animals;

[0005] 3. During the hatching process of these aquatic animals, the newly born larvae are easily eaten by the mother or natural enemies, resulting in a low survival rate of the seedlings;

[0006] 4. There is no way to clean up the leftover bait and feces in time, and it is easy to rot, deteriorate, and damage the water quality, resulting in a large number of deaths of aquatic animals;

[0007] 5. Many aquatic animals must be covered with sheds for winter breeding, but the water body area is limited, and it is impossible to carry out high-density breeding, and the cost of building sheds is very high if they are spread out evenly;

[0008] 6. Due to the influence of the above factors, the yield per mu is low, the cost of breeding is high, and it is difficult to observe the situation of breeding in the water, and it is impossible to know some more accurate data, such as survival rate and distribution;

[0009] 7. In the era of resource shortage, when large-scale and large-scale farming is required, it is becoming more and more difficult to find land resources that can satisfy large-scale farming and abundant water sources

[0010] 8. Inbreeding cannot be effectively avoided, resulting in a decrease in the quality of the seedlings year by year, and it is difficult to raise them

[0011] To sum up, the existing aquaculture methods have low utilization rate of water body space, low breeding density, low survival rate of aquatic animals, and high cost
