The invention discloses a variable-flow intelligent control system based on fish school behaviors and bottom pollution discharge characteristics. The system comprises a circulating water culture pond, a circulating water treatment system, a feeder, a high-definition camera, a variable-frequency water pump, a computer, a PLC and the like. The system mainly utilizes a machine vision technology and a computational fluid mechanics simulation technology to analyze and evaluate sludge discharge at the bottom of the culture pond, so as to formulate a variable-speed flow strategy. The variable-flow intelligent control system is simple in structure, the method is accurate, simple and convenient, the intelligent variable-flow system is suitable for a recirculating aquaculture mode, and the problems that in an existing recirculating aquaculture system, bottom sludge is difficult to discharge, water flow dead zones exist, water quality becomes poor, and growth welfare of fishes is affected can be effectively solved. 本发明公
