South American eel integrated culture system

Abstract

The invention provides a South America eel integral breeding system which comprises a breeding pond set formed by sequentially connecting a plurality of breeding ponds. The system further comprises an inflow water buffering device, a heating and filtering circulating water device and a blood worm temporary rearing self-cleaning device. The inflow water buffering device has the functions of purifying and buffering water flow through design of the multiple sets of ponds, the heating and filtering circulating water device achieves heating safety through a heating isolation mode and meanwhile has the function of filtering water in the breeding ponds, and the blood worm temporary rearing self-cleaning device achieves the blood worm cleaning function by manually arranging a water channel simulating a riverway. The system has the advantages that the processes of introducing water from an eel water source to the eel breeding ponds, heating the water, purifying the water, feeding the eels and the like are achieved at a time, the processes are optimized, the death rate of the eels is low, the automation degree is high, and waste of water resources is reduced.

Description

technical field [0001] The invention belongs to the field of eel culture of marine aquatic fish, in particular to an integrated eel culture system in South America. Background technique [0002] Eel, the scientific name is eel, and its species are commonly known as eel, conger eel, flower eel, bicolor eel, etc. It is an aquatic animal that lives naturally in the ocean. According to marine historical records, it is speculated that the eel spawning sites in China and Japan may be in the Philippines and Malaysia. deep sea among the islands. At present, artificial breeding of eel seed has not been successfully studied and reproduced. Over the years, eel seed resources have mainly been imported from Europe. Now European eel species have been listed in my country's international protection of endangered wild animals and plants. One of the new species of South American eel is an economic fish eel species introduced in the past two years. At present, the imported South American eel...

Problems solved by technology

[0004] In the prior art, there is no facility dedicated to flushing and temporarily storing red worms. The existing methods are either simple rinsing to remove mud, or simple ablation cleaning, or investing in cleaning equipment, or investing a large amount of disinfectants. The above-mentioned methods are difficult to clean, so the occurrence of pathogenic bacteria colonies is unavoidable, or there are factors of diseases and insect pests that make it difficult to ensure sufficient water source and cleanliness of water quality, or eels are prone to parasites, or to ensure the cleanliness of water quality, corresponding The cost of input is very high, which restricts the water quality and sufficient amount for eel farming, and restricts the development of breeding technology

[0005] 2. In the existing sewage discharge device for aquaculture ponds, a filter screen is usually installed at the bottom of the pond, and the sewage settled at the bottom of the pond is discharged to the drainage ditch through the filter screen. However, due to the large area of ​​the bottom of the aquaculture pond, the discharged sewage At the same time, a large amount of pool water is drained, and the concentration of pollutants in the drained pool water is not high, which is easy to cause waste of pool water

However, a small area formed by isolation after corner chamfering is usually filled or shelved, resulting in waste of space or a place where garbage and waste are gathered, resulting in hygiene problems that are not conducive to the growth and reproduction of cultured organisms

[0007] 3. Most eel fry are raised in winter, and the water in the breeding pool must be heated during the feeding period of the eel fry. The traditional feeding and heating method is to directly insert a steam pipe into the water in the breeding pool, and directly feed the boiler pressure steam into the breeding pool. Heating the pool water; or using simple heat insulation in the breeding pool water, or investing in high-cost heating equalizer equipment, or having no approved technology for uniform heating facilities, or using multiple heating steam pipes dispersedly inserted into the breeding pool Turn on the steam to heat the water body, and the generated steam or superheated steam will beat the waves and hurt the eel fry, or when heating the eel fry pond water during breeding, use simple steam isolation measures to reduce the temperature of the rearing pool water. Increase, the above heating methods are all likely to cause superheated steam water or superheated water to directly scald the eel fry, the light one will affect the uneven water temperature of the rearing pool water and the feeding process is difficult to control, and the severe one will cause high mortality of eel fry and increase the investment cost of eel fry

However, in the existing industry work, a large amount of supplementary water is directly flushed into the culture pond through the rapid flow, which causes potential danger to the cultured organisms: pumping water from the water source, due to the excessive force of the pump, it is easy to sink The sand or other impurities on the bottom of the water are pumped to the breeding pond, which reduces the cleanliness of the water in the breeding pond and loses the meaning of replacing it with fresh water

The water output is large and the water flow is fast, and its excessive impact force is likely to cause damage to the cultured organisms

In order to avoid the above drawbacks, invest in high water uniformity equipment, or simply extract surface water, or directly impact a large amount of water into the aquaculture pond, or use a simple treatment method with poor water uniformity, or ignore the effect of the aquaculture process, The above water intake methods are directly flushed into the breeding pond, which will lead to an increase in the casualty rate of the eel fry, which makes the investment cost very high
