<P>PROBLEM TO BE SOLVED: To provide a fish bank made of woody columns, capable of exhibiting fish-attracting effects as the fish bank for a long period of time by promoting the utilization of thinned wood. <P>SOLUTION: The fish bank made of the woody columns is composed of a bottom frame body 2 for keeping the fish bank in a state sunk in seawater, and a plurality of the column bodies 1 fixed to the bottom frame body 2. The column body 1 has an outer cover constituted of a wire net 6 or a punched metal enabling the seawater to come and go, and a cavity in the inside. The cavity is filled with woody chips. A metallic prop 1b is erected in the interior of the cavity of the column body 1. A lid 9 is attached to the head part of the column body 1. A bottom plate 3 is attached to the bottom part of the column body 1 by attaching the bottom plate 3 to the bottom frame body 2 with bolts 7 and nuts so as to be freely detachable. The fish-attracting effects are heightened because the column body 1 is composed by being filled with the woody chips to increase spaces in the column body 1, to allow many insects and shellfish becoming bait for the fish to live therein and to allow much seaweed to emerge. <P>COPYRIGHT: (C)2013,JPO&INPIT |
