Sea fish culture net cage capable of being lifted and rotated

The utility model discloses a marine fish culture net cage capable of being lifted and rotated. The marine fish culture net cage comprises a structural floating body, a culture net cage body, a lifting mechanism and a rotating mechanism. Wherein the structural floating body floats on the water surface, a hanging bracket is arranged on the structural floating body, the lifting mechanism is arrangedon the hanging bracket, the lifting mechanism is connected with the aquaculture net cage body, and the aquaculture net cage body ascends/descends relative to the structural floating body through thelifting mechanism; the surface of the aquaculture net cage body is coated with a fishing net; and the rotating mechanism is arranged on the structural floating body and is connected with the aquaculture net cage body, so that when the aquaculture net cage body is in a descending state, the rotary net drying of the aquaculture net cage body is realized. The net cage has lifting and rotating functions, reduces net cage draug
