Problems solved by technology

[0002] Murray cod is a freshwater fish native to the Murray Darling River Basin in southeastern Australia. It is widely loved by local Australians because of its delicious taste and firm meat. In recent years, domestic aquaculture enterprises have also begun to introduce Murray cod. Trial breeding was carried out, and with the continuous development of technology, the domestic Murray cod breeding technology has gradually matured, and the existing Murray cod breeding method is to ensure the growth and development of Murray cod by strictly controlling water flow, temperature, and water body oxygen content , but the existing Murray cod culture method requires a large amount of water replenishment during the breeding process, resulting in a large change in the water temperature and water quality of the Murray cod growth environment, resulting in poor survival rate and health status of the Murray cod

Embodiment 1

[0038] seefigure 1 , Figure 3 to Figure 5 , This embodiment provides a recirculating aquaculture system for Murray cod, which is applied to the cultivation of Murray cod fry. Compared with Murray cod fry, the requirements for water quality are lower, and they mainly feed on plankton.

[0039] The Murui cod circulating aquaculture system of this embodiment includes a culture pond 01 and a water body circulation system, and the culture pond 01 is connected in a closed loop with the water body circulation system; the water body circulation system includes a filter device 02, a biochemical pool, a purification Pool and aeration mechanism 03, the water discharged from the culture pond 01 flows back into the culture pond after passing through the filter device 02, the biochemical tank and the purification pond in turn; the filter device 02 is used to filter suspended solids in the water body; The biochemical pool is used to cultivate fungi to consume and decompose waste in the wate...

Embodiment 2

[0077] see Figure 2 to Figure 5 , This embodiment provides a Murray cod circulating aquaculture system, the difference from Embodiment 1 is that the biochemical pool is set in a different way, which is applied to the Murui cod fish breeding, and the Murray cod fish has water quality requirements Higher, mainly feed as staple food.

[0078] Its biochemical pool of Murray cod circulating type aquaculture system of the present embodiment comprises anaerobic biochemical sub-pool 041 and aerobic biochemical sub-pool 043, and the outlet end of anaerobic biochemical sub-pool 041 is communicated with aerobic biochemical sub-pool 043; The water inlet end of the anaerobic biochemical sub-pool 041 communicates with the filter device 02, and the water outlet end of the aerobic biochemical sub-pool 043 communicates with the purification pool; the anaerobic biochemical sub-pool 041 is used to cultivate anaerobic bacteria; the well Oxygen biochemical pool 043 is used to cultivate aerobic b...

Abstract

The invention provides a circulating type aquaculture system for maccullochella peelii. The circulating type aquaculture system comprises a culture pond and a water circulating system, wherein the culture pond is communicated with the water circulating system in a closed loop. The water circulating system comprises a filter device, a biochemical tank, a purification tank and an oxygen aeration mechanism, wherein water discharged from the culture pond passes through the filter device, the biochemical tank and the purification tank in sequence and flows back into the culture pond; the filter device is used for filtering suspended solids in the water; the biochemical tank is used for culturing bacteria to consume and decompose wastes in the water; the purification tank is used for clearing harmful substances and bacteria in the water away through ozone and ultraviolet rays; the oxygen aeration mechanism is used for increasing the content of oxygen in the water. The circulating type aquaculture system for the maccullochella peelii is used in a maccullochella peelii breeding method. By means of the circulating type aquaculture system for the maccullochella peelii, the water source utilization rate can be improved, energy is saved and emissions are reduced. The maccullochella peelii breeding method can increase the growth and development speed of the maccullochella peelii.
