The utility model relates to a composite wear-resistant elastic fabric applied to the field of fabric parts, which is used for waistcoat clothes and comprises composite wear-resistant elastic fabric cover layers, outer reflective coatings are fixedly connected to the ends, far away from each other, of the two composite wear-resistant elastic fabric cover layers, and wear-resistant coatings are fixedly connected to the inner ends of the outer reflective coatings. The composite wear-resistant elastic cloth cover layers are arranged on the front side and the rear side of the waistcoat, the outer reflective coating is arranged on the front side and the rear side of the waistcoat, the waterproof coating is fixedly connected to the end, away from the outer reflective coating, of the wear-resistant coating, and the inner warning coating is fixedly connected to the end, away from the waterproof coating, of the outer reflective coating. The outer reflective layer covers the photosensitive coating inner ball of the inner warning layer when the outer reflective layer is worn and is not worn, the photosensitive coating inner ball is sensitive to ultraviolet rays, and the photosensitive coating inner ball is exposed to sunlight and changes color after being worn, so that a user is reminded that the outer reflective layer is worn so as to repair the fabric in time, and the service life of the fabric is prolonged.

To provide a method for appropriately setting the intensity of ultraviolet rays at a flow rate at which optimum power efficiency is obtained in order to prevent infection to individuals in other water tanks even if an individual in one of a plurality of water tanks develops an infectious disease in a water circulation system.SOLUTION: The management device 100 is configured to, based on a sterilization target value including a safe maximum viable cell count and an allowable immersion time, bacteria information including a viable cell count increase amount indicating the number of bacteria released into water per unit time by the aquatic organisms having developed infectious diseases and ultraviolet light sensitivity information of bacteria to be sterilized, and rearing condition information including a plurality of water tank 20A, a water amount of 20B, the number of water tanks, and a lower limit flow amount of a pump, A specifying unit configured to set an ultraviolet target intensity of the ultraviolet light source so that the number of viable bacteria in at least one of the plurality of water tanks falls below the safe maximum number of viable bacteria within the allowable immersion time when the set flow rate of the pump is set to a target flow rate based on a lower limit flow rate.SELECTED DRAWING: Figure 1
