The invention relates to an anti-current deformation device and a control method for a netting system of a deepwater net cage, relating to the technical field of marine net cage culture. The device comprises a main frame (1) of a gravity-type deepwater net cage, a netting (2), net ribs (3), an underwater anchoring frame (4) of the net cage, corner nodes (5) of the underwater anchoring frame, anti-current rope frame (6), guyed ropes (7), a net cage foundation ring (8), a net bottom (9) and rope frame balance weights; the device utilizes the underwater anchoring frame system (4) of the existingdeepwater net cage and the corner nodes (5) of the underwater anchoring frame as a basic platform, a polygon frame system formed by flexible ropes are used for forming an anti-current device (6), theguyed ropes (7) are used for applying the horizontal towing force opposite to the direction of ocean current to the netting system of the deepwater net cage, and the horizontal displacement of the netting system is controlled
