High-density special aquatic product breeding system with land sea fresh water

Abstract

The invention discloses a high-density special aquatic product breeding system with land sea fresh water. The high-density special aquatic product breeding system comprises a water inlet device, a water outlet device and at least one breeding device, wherein the bottom part of the breeding device is provided with an opening, the water inlet device is connected with a water inlet hole of the breeding device through a small tube, and the water outlet device is connected with a water discharge hole of the breeding device through a small tube. The high-density special aquatic product breeding system with land sea fresh water disclosed by the invention has the advantages that the manufacturing cost is low, the breeding cost is saved, the land resource is saved, and the special aquatic product can be bred in sites such as the periphery of a house, an embanked courtyard and indoors.

Description

technical field [0001] The invention relates to an aquaculture system, in particular to a land sea freshwater high-density special aquaculture system. Background technique [0002] At present, people have successfully carried out large-scale artificial breeding of many types of seawater and freshwater fish and shrimp. The breeding technology is very mature, but it also has the following shortcomings: [0003] 1. The breeding grounds cannot resist the invasion of floods, droughts, extreme heat and severe cold. [0004] Second, the cultured animals are prone to diseases and large-scale infection of diseases. [0005] Three, cultured thing escapes, fails to effectively solve all the time as prior art to the escape problem of aquatic products such as crayfish, rice field eel. [0006] 4. The cultured animals attack and cannibalize each other. For example, crayfish and eels will attack each other because of competition for food when there is insufficient food. Shrimp and eels i...

AI Technical Summary

Problems solved by technology

[0003] 1. The breeding grounds cannot withstand the invasion of floods, droughts, extreme heat and severe cold

[0004] 2. Breeding products are prone to diseases and large-scale infection of diseases

[0005] 3. The escape of cultured animals, such as the escape of aquatic products such as crayfish and eels, has not been effectively solved in the prior art

[0007] 5. The unit output value of the farm is not high. The existing technology has always been limited to cultivating various aquatic products in natural water bodies or artificial ponds. Due to reasons that cannot be overcome by the existing technology, the output per mu cannot reach 2000 kg

[0008] 6. The fixed investment of the breeding system is high, and it is not suitable to be promoted to the general public. The existing technology often needs to rent several acres or tens of acres of farmland for breeding. The rent alone has a high investment, not to mention seedlings, feed, and medicines. and labor, etc., and it is a large investment with little return and unstable development prospects

[0009] 7. The aquaculture system consumes a lot of water. Due to the large area of ​​the existing technology, a large amount of water is needed every time the water is changed, resulting in extremely low water utilization

[0014] 12. The problem of natural enemies of cultured animals, although traditional breeding techniques have some preventive measures, they have not been completely eliminated
