Carbon-sink-increasing-type marine ranch

The invention relates to the technical field of marine ranch carbon sink increasing, and discloses a carbon-sink-increasing-type marine ranch. The carbon-sink-increasing-type marine ranch comprises amarine ranch breeding area located near a coastline and defined by breeding net cages, aquatic products are bred in the marine ranch breeding area, and artificial reefs are stacked in a sea area in the marine ranch breeding area; the artificial reefs are evenly distributed in the marine ranch breeding area, and any three adjacent artificial reefs are arranged in a regular triangle shape from the perspective of a top view; second fan blades, third fan blades and a water flow promoting structure in the artificial reefs rotate to drive seawater around the artificial reefs to flow rotationally, the seawater flowing rotationally generates an artificial ascending water flow, the ascending water flow conveys bottom-layer nutritive salt to the surface layer, breeding of phytoplankton in a water body is promoted, and the e
