The invention relates to a water surface rotary carrier farming and fishery stereoscopic production automatic system. The water surface rotary carrier farming and fishery stereoscopic production automatic system comprises a water surface crop planting system, a water body aquatic animal breeding system and a control system; the water surface crop planting system comprises round water surface floating beds, a floating bed positioning and rotating device, a crop growth monitoring device and a farm operation mechanical device; the floating bed positioning and rotating device fixes the round water surface floating beds on a water surface, and can drive the round water surface floating beds to rotate; with respect to each round water surface floating bed, a plastic pipe is adopted as a buoy to surround into a round floating bed box body, with respect to the round floating bed box body, a plastic net is adopted as a bottom to load a culture medium, and the center of the round floating bed box body is a euphotic fishing area; the euphotic fishing area is internally provided with a bridge pier, the four round water surface floating beds constitute a small unit, the two sides of the small unit are provided with a work road to facilitate farming and fishery harvest and transportation, and the center of the small unit is used as a fishing area; a work bridge is arranged between the work road and the bridge pier which are above the round water surface floating beds. According to the water surface rotary carrier farming and fishery stereoscopic production automatic system, idle waterborne resources are fully utilized to achieve farming and fishery stereoscopic automatic production.
