A seabed depletion phenomenon in which useful seaweed becomes barren because the seabed rocks and sediments are exposed and covered with no-seed lime algae, and seaweeds are drastically reduced or disappeared. One of them is the damage caused by herbivorous animals such as sea urchin and abalone. As a countermeasure, humans have traditionally dived into the sea floor to collect these herbivores. Because of this, the conventional method requires personnel who can dive and the number is naturally limited,
It takes a lot of time and money.

Flows at high speed along the lower wing surface toward the lower end 5un of the pumping pipe 5w. Therefore, seawater near the lower surface of the negative pressure generating blade 3 also flows in parallel at high speed. This water flow, like an aircraft wing, creates a negative pressure on its wing side, that is, between this wing surface and the seabed. By this action, the seabed herbivorous animal separated by the jet water from the nozzle is sucked up to near the lower surface of the negative pressure generation wing 3, and is carried by the high-speed flow flowing thereabout to the lower end 5un of the pumping pipe. The sea urchin guided to the lower end 5un of the pumping pipe is pumped together with the pumping water through the pumping pipe 5w and collected on the submarine herbivore collecting basket 12.
