Embodiment 1

[0038] See figure 1 The concentrated internal circulation fish farming method of the present invention mainly uses aeration to push water, so that the water body flows in the pond to form an internal circulation and increase dissolved oxygen. A high-density farming method carried out in cement breeding ponds. The concentrated internal circulation fish farming technology equipment is mainly composed of 5 systems, namely the aeration and pushing water system, the concentrated breeding system, the bait feeding system, the sewage collection system and the pond self-purification system. There are multiple aeration and water pushing systems, which are respectively placed in the upstream of the aquaculture pond along the water flow in the agglomeration aquaculture system to push the water body of the aquaculture pond to surge downstream and increase dissolved oxygen at the same time. In the agglomeration culture system, the culture pond is connected to the aeration and water pushin...

Embodiment 2

[0050] Use the gathering type internal circulation fish culture equipment of the present invention to carry out fish farming, set up 5 culture ponds per 30 mu of ponds, each culture pond has a volume of 200 cubic meters, and is equipped with 1 aeration and water pushing equipment. 10,000 grass carp are stocked in each breeding pond, and the target output is 20,000 kilograms. Converted according to the area of ​​the purification pond, the yield per mu is 3,300 kilograms. Grass carp is only cultured in 5 breeding ponds, and the feeding of bait is convenient, reducing the use of labor. At the same time, the water body is purified by a pond with an area of ​​30 mu, so that the water quality can be maintained at a high level without a large number of water changes.

[0051] Grass carp are stocked in the first ten days of March every year, and the domestication work is carried out when the water temperature reaches 15°C. Because the water body is constantly in a state of turbulence...

Abstract

The invention discloses an aggregated internal cycle fish farming device. The aggregated internal cycle fish farming device includes an aeration water pushing system, an aggregated farming system, a mechanical feeding system, a dirt collection system and a pool self-cleaning system; the aeration water pushing system pushes water to successively enter the aggregated farming system, the dirt collection system, and the pool self-cleaning system, and then one or more aeration water pushing systems arranged in the pool self-cleaning system push the water to the aggregated farming system so as to form a water large cycle. The aggregated internal cycle fish farming device can solve the problem of high density farming in dynamic water, can improve the utilization rate of soil, can increase the yield and economic benefits, can maintain high density farming water quality, can effectively collect fish metabolin, and can save water resources.

Description

technical field [0001] The invention relates to a method for raising fish, in particular to an equipment and a method for raising fish with circulating water in an accumulation pond, and belongs to the technical field of aquaculture engineering. Background technique [0002] At present, many experiments and researches have been carried out at home and abroad based on industrialized recirculating aquaculture to achieve high yield, energy saving and emission reduction. Some scholars have also carried out research on the method of recirculating aquaculture to improve water quality through physical filtration or aquatic plant purification through ponds. However, the research on the concentrated internal circulation culture and the collection of metabolites through pond transformation has not been carried out, and there are no literature reports. [0003] Physical filtration is generally used in artificial breeding or industrial farming. It is mainly a process of physically sepa...
