Wherein a water inlet of one pipeline is communicated with a discharge port of a double-path discharger in the culture pond body, a water outlet of the other pipeline is communicated with a water discharge ditch outside the pond, the double-path discharger comprises a large water discharge port and a small water discharge port, and the small water discharge port is communicated with a pipeline inlet of a lateral sedimentation pond. And the large water outlet is connected to the culture pond water draining ditch through a water draining pipe. The healthy breeding system with the fish toilet is
