The present invention relates to a jellyfish capturing device (1) with which jellyfish can be captured in quantity by means of a net. The present invention includes: a metallic inflow frame (3) configured to be coupled with an inlet of a front inflow portion (21) of a sack net (2) having the front inflow portion (21) open forward and a back storage portion (22) coupled with the back of a front inflow portion and having a back end configured to be closed； a front buoy (4) connected to a depth adjustment rope (7) adjusting the depth of the inflow frame (3) by being connected to an upper side of the inflow frame (3) and a ship (A) with both front sides of the inflow frame (3) being connected to the ship (A) by a traction rope (6)； a back buoy (5) connected to a back end of the back storage portion (22) by a supporting rope (8)； and a salvage rope (9) having both ends connected to a net hauler (B) of the ship (A) and surrounding a boundary portion (23) between the front inflow portion (21) and the back storage portion (22). According to the present invention, various species of jellyfish can be captured in quantity, and the boundary portion (23) is squeezed during salvage so that the jellyfish can be captured alive, jellyfish losses can be prevented, and the jellyfish can be provided with freshness as food. In addition, the present invention can forestall accidents, fishing losses, and industrial facility damage attributable to jellyfish, have positive economic effects, and have many other positive effects.본 발명은 해파리를 그물을 이용하여 대량으로 포획할 수 있도록 한 해파리 포획장치(1)를 제공하는 것으로서, 상기 본 발명은 전방으로 개방되게 형성된 전반유입부(21)와 전반유입구의 후방으로 결합되어 후단이 폐쇄되게 구성된 후반저장부(22)로 이루어진 자루그물(2)의 전반유입부(21) 입구에 결합 구성된 금속제 유입틀(3)이 구비되며, 유입틀(3)의 전면 양측이 견인로프(6)로 선박(A)과 연결 구성되면서 유입틀(3)의 상측과 선박(A)에 연결되어 유입틀(3)의 깊이를 조절하는 깊이조절로프(7)가 연결된 전방부표(4)가 구비되며, 후반저장부(22) 후단과 지지로프(8)로 연결 구성된 후방부표(5)가 구비되며, 전반유입부(21)와 후반저장부(22)의 경계부(23)를 둘러싸면서 선박(A)의 양망기(B)에 양단이 연결된 인양로프(9)가 구비된 것을 특징으로 하며, 이러한 본 발명에 의하면 각종 해파리를 대량으로 포획할 수 있으며, 인양 시
