Abstract

The invention relates to a net cage for breeding erythroculter ilishaeformis. The net cage comprises a cuboid frame. A polyethylene net encircles the outer side of the frame. An inlet is formed in the polyethylene net on the side face of the frame, and is connected to a cone-shaped channel. An upper rope of the frame is connected to a floating ball. A lower steel rope of the frame is connected to an anchoring block. Erythroculter ilishaeformis is bred in the net cage. Some small trash fishes and shrimps can be also captured to provide natural bait for erythroculter ilishaeformis simultaneously when erythroculter ilishaeformis is bred.
