Abstract

PURPOSE:To facilitate the recovery of red tide planktons by floating up the red tide planktons to places near to the surface of sea by the aeration treatment of the red tide planktons in sea water. CONSTITUTION:Red tide planktons are surrounded, and air is subsequently bubbled at a proper water depth to aerate the red tide planktons. The floated red tide planktons floated up to places near to the surface of sea are sucked up with a pump and recovered. The device for the recovery of the red tide planktons is provided with a circular float for surrounding the red tide planktons, a curtain suspended from the circular float an air bubble-generating device set at a place having a proper water depth below the surface of the sea at the center of the circular float and used for generating the air bubbles, and a suction ship placed in the circular float and used for sucking up the red tide planktons floated at places near to the surface of the sea. The circular float preferably comprises a hose floated by the charging of air, and the hose is communicated and connected with the air bubble-generating device through a hose.
