The invention discloses a safe summer spending method for natural mariculture of verasper variegatus and belongs to the technical field of aquaculture. The safe summer spending method for the natural mariculture of verasper variegatus includes that regulating cultivation density, increasing dissolved oxygen, increasing stream flow, reducing bait feeding amount and feeding immune stimulant. By means of the safe summer spending method for the natural mariculture of verasper variegatus, even if the water temperature arrives at 28 degrees centigrade in summer, the survival rate of the verasper variegatus in the farm of the north of China which only depends on the natural mariculture can arrive at 95%, and accordingly the verasper variegatus cultivation popularization region is expanded. Compared with a cultivation method of using refrigeration water to cool in summer, the safe summer spending method for the natural mariculture of verasper variegatus can obviously lower the cost.
