Circulating type aquaculture system for maccullochella peelii and maccullochella peelii breeding method

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.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a Murray cod circulation type aquaculture system and a Murray cod culture method. Background technique [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, and with the continuous development of technology, the domestic Murray cod breeding technology is gradually mature, 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 large changes in the water temperature and water quality of the Mu...

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
