AEROGYDRODYNAMIC KEY BUOY AND METHOD OF CROPPING OF SURFACE OBJECTS OF FISHING Russian patent published in 2018 - IPC A01K74/00 

FIELD: agriculture.

SUBSTANCE: method involves preparation of a cascade filtering-type fishing gear, while one end of the fishing gear is provided with a hydrodynamic anchor, made in the form of a parachute and connected to a signal buoy through stay bars. The other end of the fishing gear is equipped with a key buoy. It is connected to the hydrodynamic anchor through the system of stay bars allowing the hydrodynamic anchor to be in stagnation in a water column at the required level, and to the key buoy using the aerodynamic power of wind and hydrodynamic power of water - on the water surface. The key and the signal buoys are equipped with radio beacons. Choose the place of fishing, set the fishing gears, stagnation, select the fishing gear and pull out a catch. The key buoy includes a cylindrical body, inside which there is a holding device for additional elements, and a light source. The cylindrical body is executed moulded with a through cylindrical hole in the center. The holding device for additional elements is made in the form of a cylindrical rod and is located inside a cylindrical hole, with the upper and lower tips of the rod provided with lifting rings. The cylindrical body along the perimeter is equipped with aerohydrodynamic valves, which allow to use aerodynamic power of wind and hydrodynamic power of water.

EFFECT: increase in fishing efficiency.
