The invention belongs to the technical field of fishery engineering machinery and discloses a simple trawl fishing system for an aquaculture pond. The front and back ends of both sides along the length direction of a pond (G) are provided with a ground pile (1) respectively; a steel wire guide rope (2) is tightened between the ground piles (1) at the front and back ends of each side respectively;the two transverse ends of a net bag (3) are drawn onto the steel wire guide ropes (2) on both sides respectively and are connected to ferrules which are inserted into the steel wire guide ropes (2);the ferrules are dragged by net dragging steel wire ropes (4); two net dragging steel wire ropes (4) respectively pass through the ground piles (1) sleeved at front ends, are combined and introduced into left and right net dragging winches (53, 54) in a traction device (5); power is supplied to the left and right net dragging winches (53, 54) by a tractor (6); the traction device (5) comprises a transportation vehicle (55), which is arranged on a trailer, on a guide rail (56) accordant with the length direction of the pond (G) during running; and a transportation vehicle traction winch (58) which is guided by a rope guide pulley wheel (57) is arranged behind the transportation vehicle (55). The system has a simple structure, is convenient to operate, drags a fish net quickly, greatly saves labor force and time and improves working efficiency.
