Background
Most of the current cultured fishes are cultured in ponds, the water level is large, the water quality is difficult to control, and due to the reasons of bait investment, excrement of the fishes, various slag enrichment and the like, feed which sinks to the bottom of the pond quickly decays and goes bad, so that the water environment of the fish pond is deteriorated, and the water quality needs to be updated. The existing method is to dig a water inlet ditch and a water drainage ditch for water replacement. The water inlet ditch and the water outlet ditch in the method for changing water are both arranged at the upper part of the fish pond wall, only the water quality at the upper part of the fish pond can be changed, and the dirt at the bottom layer cannot be treated.
Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. Generally comprises the whole process of cultivating aquatic products from seedlings under artificial feeding management. In a broad sense, this may also include the proliferation of aquatic resources. Aquaculture has modes of rough culture, intensive culture, high-density intensive culture and the like. The rough culture is to put seedlings in medium and small natural waters and to culture aquatic products such as fish in lakes and reservoirs, shellfish in shallow seas and the like by completely relying on natural baits. Intensive culture is to culture aquatic products such as pond fish culture, net cage fish culture, fence culture and the like in a small water body by using bait casting and fertilizing methods. The high-density intensive culture adopts methods of flowing water, controlling temperature, increasing oxygen, feeding high-quality baits and the like to carry out high-density culture in a small water body so as to obtain high yield, such as flowing water high-density culture of fish, shrimps and the like, the culture water needs to be heated and insulated in the culture process, and therefore, a heat-insulating device for fish water circulation culture is needed

Example 2
And (3) comparison test:
the variable flow type circulating culture method, the variable flow type circulating culture device and the variable flow type circulating culture method are respectively compared with the common circulating culture method and the common circulating culture equipment in the market:
the aquatic product used in the test is crucian, the crucian is purchased on the same day in the test, the test is carried out immediately after the crucian is transported, no manual treatment is carried out, and the weight of a single head is about 90 +/-3 g.
In the experiment, the variable flow type circulation culture method and the variable flow type circulation culture device are set as a test group, the conventional common circulation culture method and the conventional common circulation culture device are set as a control group, and 120 crucian carps are respectively placed in culture ponds with the same size, environment and water quality for culture for 1 year.
Table 1 test evaluation results table
| Test group | Control group | |
| Survival rate | 100％ | 92％ |
| pH value of water body | 7.1 | 6.5 |
| Content of ammonia and nitrogen | 0.002mg/L | 0.03mg/L |
| Dissolved oxygen | 10mg/L | 4mg/L |
