The invention discloses an HDPE self-tension flat bottom lift type anti-current net cage system and a control method, and relates to the field of seawater net cage culture facilities. The system consists of a spherical net cage main frame (1) constructed by HDPE pipes, a high-strength pulling rope (2) for fishing, a central gravity netsuke self-balancing device (3), a mesh (4), an HDPE pipe exhausting and inflating port (5) of, a high-strength exhaust and inflation flexible pipe (6) and an HDPE inlet and outlet pipe mouth (7). The system has the advantages of reasonable design principle, concise and feasible structure, low manufacturing cost, easy operation, good anti-current performance of the net cage structural system, large underwater culture platform, multilayer three-dimensional culture, space saving, and improvement on benefit, can sink to water bottom or stay in different water layers, is flexible and mobile, can avoid the attack of typhoon and red tides, can culture different kinds of fish, and has w
