The floating frame includes an upper rectangular frame and a lower rectangular frame arranged up and down. The upper rectangular frame and the lower rectangular frame are both surrounded by PVC pipes and are connected by PVC connecting pipes; the net cage matrix includes a netting with an open upper end. A connecting rope is connected to the netting. The top of the connecting rope is detachably connected to the floating frame, and the bottom of the connecting rope is connected to a stainless steel sinking frame. The utility model can effectively prevent fry from escaping, and the net cage matrix can be fully unfolded in water without fixing the corners of the net cage matrix. Through the detachable connection between the connecting rope and the floating frame, the mesh size of the net cage matrix can be changed and adjusted according to the size of the fry put in. The floating frame enables the net cage matrix to be suspended in the water in the best state, eliminating the need for buoyancy balls, and is simple to manufacture, which can effectively make the fry breeding net cage for a pond stable and non-tilting in water.
