Micropterus salmoides breeding device and breeding method

The invention relates to a micropterus salmoides breeding device and method, and belongs to the technical field of aquaculture. The breeding device comprises a breeding pond, a settling pond and a purifying pond, the fish fence grid is arranged above the conical bottom of the lower portion of the culture pond in the radial direction, fish manure and residual feed are prone to settling to the position below the fish fence grid and flow to the settling pond along with water, and the speed of separating culture waste from the culture pond is increased. The sedimentation tank is used for oxygenolysis of organic matters in tail water of the culture pond to achieve the effects of nitrogen fixation, phosphorus removal and water purification. The area of the purification pond is 100 times that of the culture pond, the interior of the purification pond is divided into a shallow water part and a deep water part, and the purification pond is used for continuously absorbing residual nutritive salt such as nitrogen and ph
