CULTIVATION-TYPE ULTRAHIGH FISH REEF AND ARTIFICIAL REEF UTILIZING THE SAME

摘要

PURPOSE: To provide an ultrahigh fish reef capable of being set in a highly deep undersea area by a usual floating crane. CONSTITUTION: More than three pieces of towerlike structural materials 19 to 21 are combined on an upper side of a structural base material 18 prepared by piling a block with steel materials, etc., to form an ultrahigh fish reef 12 of 35m high as a whole, a horseshoe-shaped horizontal structural material 20 is crosslinked so as intermediate parts of the towerlike structural materials 19 to 21 to be connected, an opened part 46 into which a top end of a crane boom 45 is penetrable is placed along a height direction on one side of the towerlike structural material and pseudo-rocks 44 as adherent substrates are stuck on outside faces of the horizontal structural material 20. The fish reef can be pulled up by a usual crane because of the existence of the opened part 46, and a field for spawning and conservation/nursery even in a middle layer region or a high layer region can be provided by the pseudo-rocks 44.
