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.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.【課題】間伐材を利用を促進し、かつ漁礁の集魚効果を長期間発揮できるようにした木柱製漁礁を提供する。【解決手段】海水中で沈下状態に保つ底枠体２と、底枠体２に固定された複数本の柱体１とからなり、柱体１は、海水の出入りが可能な金網６やパンチングメタルで外皮が構成され、内部は空洞であり、空洞の内に、木質チップが充填されている。柱体１の空洞の内部で金属製の支柱１ｂが立設されている。柱体１の頭部に蓋９が取付けられている。柱体の底部に底板３が取付けられており、底板３を底枠体２にボルト７とナットで着脱自在に取付けている。柱体１が木質チップを詰め込んだものであるため、柱体１内に空隙が多くなり魚の餌となる虫や甲殻類が多数住み着き、また海藻の発生も多くなる。このため、集魚効果が高くなる。【選択図】図１
