The invention belongs to the field of fish breeding and particularly relates to a net cage device for fish farming. The net cage device for fish farming comprises a fixing frame, a purse net is fixed on the fixing frame, the fixing frame is supported on water surface through a plurality of floaters, the fixing frame comprises a plurality of fixing units, and each fixing unit comprises a fastener mechanism used to fix the floaters. The fixing frame is supported on the water surface through the floaters so that the whole device may be moved and adjusted on the water surface as required; in addition, the floaters may be moved with changes in the water level so that the fixing frame is constantly on the water surface, preventing fishes in the purse net from escaping when the water level changes; the fixing frame of the invention is fastened to the floaters through the fastener mechanisms, and no extra fixation is required between the fixing frame and the floaters. The net cage device is simple in structure and ea
