A plurality of temperature sensing probes are arranged at different positions in the water product breeding pond, and the temperature sensing probes are electrically connected with the control module. Each heat conduction device is connected with the air source heat pump through a main pipeline. The heat conduction device includes a corrosion-resistant pure copper capillary tube, which is uniformly laid in the water product breeding pond.
