The present invention discloses a net
cage device for
aquaculture of sand snakeheads, comprising a net cage, a cone, a sinker, and a
rope. The net cage is formed by sewing a bottom mesh sheet and a
peripheral mesh sheet, the mesh sheet being provided with a plurality of circular holes, the edges of the circular holes being sewn to the fan-shaped mesh sheet to form an embedded cone with a closed top, the sinker being sewn to the periphery of the bottom of the net cage so that the net cage extends into the
water body; the
rope being passed through the periphery of the top of the net cage, and the
tail of the
rope being used to secure the net cage. The net
cage device of the present invention has a strong and simple structure, a long service life, is suitable for a variety of specifications, has a wide range of uses, is convenient for daily management during
aquaculture, is convenient for anytime and quantitative
fishing, reduces
fishing intensity and fish
fishing stress, and improves fishing efficiency; at the same time, it meets the needs of sand
snakehead juveniles and adult fish for a hidden
habitat, reduces spatial competition of sand snakeheads, increases the level of sand snakeheads' feeding on bait organisms, reduces
energy consumption, and promotes growth.
