This creation is a kind of pressure difference countercurrent cultivation device.It is mainly composed of an aquaculture system, a water quality treatment system and a differential pressure discharge system.The system floats individual cages in the pond.Water treatment system includes sedimentation tank and algae reservoir, ozone machine and eliminator.In the differential pressure discharge system, the electric control system is used to guide and control the water transportation and siphon operation between the aquaculture system and the water quality treatment system.The old sewage can be pumped to the sedimentation tank by the differential pressure discharge system or treated by the ozone machine.Then it is transferred to algae reservoir for treatment and returned to the breeding pond.Reduce the use of aquaculture water and ensure water quality to improve aquaculture quality.本創作係一種壓差逆流式養殖裝置，其主要由一養殖系統與一水質處理系統及一壓差排放系統所組成，養殖系統係將個別之養殖箱網浮置於養殖池中，水質處理系統則包括沉澱池與藻水庫及臭氧機和抹除器，壓差排放系統則以電控系統導引控制養殖系統與水質處理系統之間水的輸送和虹吸作用的操作，使舊污水能由壓差排放系統將汙水抽至沉澱池或經由臭氧機處理之後，再輸入藻水庫處理送回養殖池，減少養殖水之使用並確保水質來提升養殖品質。
