Specifically, as shown in fig. 4, the artificial turf 8 is laid on the bottom of the culture tank 1. Provides rest places for fishes and shrimps.

As shown in fig. 2, with reference to fig. 3, the liquid storage tank 2 is disposed below the cultivation tank 1, and a cavity 20 filled with a circulation liquid is formed between the liquid storage tank and the cultivation tank 1, a circulation liquid inlet 21 and a circulation liquid outlet 22 are disposed on the liquid storage tank 2, the circulation liquid inlet 21, the circulation pump 3, the temperature control device 4 and the circulation liquid outlet 22 are communicated with each other, and the temperature control device 4 heats or cools the circulation liquid on the liquid path. So, cool off the circulating liquid or heat to appointed temperature range through temperature regulating device 4, in the leading-in liquid reserve tank 2 of rethread circulating liquid entry 21, the circulating liquid carries out the heat exchange with 1 diapire of breed jar to heat or cool off the water of breeding in the jar 1. Specifically, the circulating liquid can be water.

In an embodiment of the present invention, as shown in fig. 5, the temperature control device 4 includes an electric heater 41, a three-way pipe 42, a valve body 43 and a circulation liquid container 44, the circulation liquid outlet 22, the electric heater 41, the three-way pipe 42, the circulation liquid container 44, the circulation pump 3 and the circulation liquid inlet 21 are sequentially communicated, and the three-way pipe 42 is externally connected to a cooling circulation liquid source through the valve body 43. The circulating liquid in the liquid storage tank 2 is led out through a circulating liquid outlet 22, heated by an electric heater 41 and then enters a circulating liquid container 44, so that the circulating liquid is heated; meanwhile, the three-way pipe 42 is externally connected with a cooling circulating liquid source through the valve body 43, and external cooling circulating liquid enters the circulating liquid container 44 through the three-way pipe 42 and exchanges heat with original circulating liquid in the circulating liquid container 44, so that the circulating liquid is cooled.

At this time, if the cooled circulation fluid is directly introduced into the liquid storage tank 2, there is a possibility that the temperature of the cooled circulation fluid is too low, which may cause irritation to the growth of fish and shrimp, and therefore, the present invention monitors the difference Δ T between the water temperature T1 and the circulation fluid temperature T2, and when the difference Δ T is within a preset difference range, pumps the circulation fluid in the circulation fluid container 44 into the liquid storage tank 2 through the circulation pump 3, and further exchanges heat with the water in the cultivation tank 1, so that the water temperature in the cultivation tank 1 is gradually lowered.

Oxygen is continuously supplied during the growth of the fishes and shrimps in the culture tank 1, so that, as shown in fig. 4, the air spray head 5, the air supply pipe 6 and the cover 7 are arranged in the invention, the air spray head 5 is arranged in the culture tank 1 and is communicated with the air supply pipe 6, fresh air is supplied through the air supply pipe 6, and the fresh air is dispersed in the water in the culture tank 1 through the air spray head 5. So for a plurality of 1 inside oxygen suppliments of breed jars keep unanimous, prevent that the inconsistent test result that leads to of oxygen suppliment from appearing the deviation.

Specifically, in this embodiment, breed jar 1 and be provided with a plurality ofly, set up side by side on liquid reserve tank 2 in proper order. The breeding tank 1 can be arranged in a cubic structure, and the adjacent breeding tanks 1 are in mutual contact, so that heat loss can be reduced, and observation and comparison are facilitated.

The cultivating cylinder 1 needs to be periodically disassembled for cleaning, and if the air supply pipe 6 is directly fixed on the cultivating cylinder 1, the disassembly and the assembly are not convenient, therefore, the air supply pipe inlet 23 and the air supply pipe outlet 24 are arranged on the liquid storage tank 2, the air supply pipe 6 penetrates through the air supply pipe inlet 23 and penetrates out of the air supply pipe outlet 24, and the air spray head 5 penetrates through the bottom of the cultivating cylinder 1 and is communicated with the air supply pipe 6.
