The present invention relates to octopus fishing banks, and more specifically, to octopus fishing banks capable of allowing an octopus to inhabit. The octopus fishing banks comprise: a main body unit (10)； and an inhabiting unit (20). The main body unit (10) includes: a plate (11) which constitutes six surfaces with concrete and forms a straight surface； and supporting legs (15) which supports the plate (11) from a ground in a lower part of the plate (11). The inhabiting unit (20) is provided in an upper part of the main body unit (10), allows one side of a cross section to be formed in a semicircular arc shape, forms an inhabiting space (21) for movement of water and inhabitation of the octopus in one side of the outside, and allows the inhabiting space to be arranged toward a different direction. The inhabiting space (21) allows a diameter to be gradually smaller from a center unit to an outer direction. Diameters of the both ends are differently formed. The present invention suppresses a phenomenon of pushing the octopus fishing banks by flexibly corresponding to a flow of the water by a moving hole (17) of the main body unit (10) and the inhabiting space (21). The present invention easily moves the octopus when moving the octopus to the inhabiting space (21). When the octopus fishing banks are used for a long time, a phenomenon of burying the plate (11) in the ground does not occur at all by the supporting legs (15) of the main body unit (10) with a spinning top method. When the supporting legs (15) are dug into the ground, the octopus fishing banks have firm fixing force in water by filling soil, sand, etc. in holes (16).본 발명은 문어어초에 관한 것으로, 보다 상세하게는, 문어가 서식하도록 하는 문어어초에 있어서, 콘크리트 재질로 6면을 이루며 표면이 직선으로 형성되는 플레이트(11)와 상기 플레이트(11)의 하부에 지면으로부터 상기 플레이트(11)를 지지하도록 구성되는 지지다리(15)로 구성되는 본체부(10)； 상기 본체부(10)의 상부에 구성되되 단면의 일측이 반원호형상으로 형성되며, 외부 일측에 물의 이동과 문어가 서식하기 위한 서식공간(21)이 형성되되, 서로 다른방향으로 향하도록 배치되고, 상기 서식공간(21)은 중앙부에서 외측방향으로 갈수록 지름이 순차적으로 작아지며 양끝단의 지름이 서로 상이하게 형성되는 서식부(
