The present invention relates to an artificial fishing reef. According to the present invention, a streamlined protrusion part (20) protrudes in a radial shape, a space (10) is formed therein, and an upper surface is curved to a bottom edge to be formed in a streamlined shape. Also, a main passage (30) is vertically perforated at the center of the upper surface, and an auxiliary passage (31) is perforated at an upper surface of the outside of the streamlined protrusion part (20) at the same time to separately communicate an internal space (10) and the outside thereof. The artificial fishing reef of the present invention comprises: a support frame (110) fastened to a main passage (30) or am auxiliary passage (31), having a support bracket (114) coupled to both ends of a support (111), cutting the center of the support (111) to be screw-coupled by an adjustment means (112), and having a support means (115) having an artificial water plant (116), coupled to the support (111)； an inner induction housing (120) fastened to a lower side of the support frame (110), formed by alternately stacking a bent plate (123), penetrating the center of the bent plate (123) of a stacked state to a vertical bar (121) to be fastened to the support frame (110), and having a plurality of artificial water plants (126) fastened to an edge and the uppermost surface of the alternately stacked bent plate (123)； and a fish trap housing (130) positioned in an inner edge space (10) of a streamlined protrusion part (20), and forming a plurality of compartments (131). Accordingly, a lower surface area is greatly formed to suppress loss even in a case of high waves such as typhoon and algae, and various passages are formed to supply an efficient spawning and resting place.상기한 목적을 달성하기 위하여 본 발명의 인공어초는 유선돌출부(20)를 방사선상으로 돌출시키고 내부에 공간(10)을 형성하되 상면을 저면 가장자리까지 만곡하여 유선형으로 형성시키고, 상면 중앙에는 수직으로 메인통로(30)를 천공함과 동시에 유선돌출부(20)의 외향측 상면에 보조통로(31)를 천공하여 내부 공간(10)과 외부를 각각 연통시키되； 상기 메인통로(30)나 보조통로(31)에 체결하되 지지대(111)의 양단
