Ocean subsurface buoy system capable of preventing fishing boat destruction and laying method thereof

The invention relates to the field of the marine environment observation, and more specifically relates to an ocean subsurface buoy system capable of preventing fishing boat destruction and a laying method thereof. The ocean subsurface buoy system comprises a subsurface buoy system for ocean monitoring and a buoy system for protecting the subsurface buoy system. The buoy system comprises at leastthree sets of anchor buoys. The anchor buoys are fixed on the seabed through a buoy anchoring system. The anchor buoys are surrounded on the sea surface so as to form a polygonal protection sea area.The subsurface buoy system is installed in the protection sea area. The ocean subsurface buoy system is capable of forming the protection sea area by surrounding of the buoy system formed by at leastthree sets of the anchor buoys, enabling a subsurface buoy carrying a monitoring device to be laid in the protection sea area for protecting, and effectively preventing the monitoring device from being destructed by a fishing b
