Embodiment 1
[0020] Example 1 Reference figure 1 and figure 2
[0021] A control method for fish farming using biogas slurry, comprising the following steps:
[0022] 1) A fish pond 10 is prefabricated. The location of the fish pond needs to be located in a mild climate, good lighting conditions, and non-polluting area; the upper side of the fish pond is provided with a biogas slurry inlet pipe 11, and the other side of the upper part of the fish pond is provided with There is an outlet pipe 12 for controlling the water level, and the bottom of the fish pond is provided with a drain pipe 13; the area of the fish pond is 1.5 mu, and the water storage capacity is 2000m 3 , install two multi-functional shallow aerobic aeration devices in the fish pond. After the fish pond is full of water, start to inject biogas slurry, and turn on the multi-functional shallow aerobic aeration device to cultivate plankton and aerobic microorganisms in the water .
