Description

A culture cage with improved structure

technical field

The invention belongs to the technical field of aquaculture equipment, and relates to a culture net cage with an improved structure.

Background technique

At present, in aquaculture, especially in large-scale aquaculture ponds and large-scale deep-water cage base aquaculture, due to the growing scale of aquaculture, the output of farmed fish is also getting higher and higher. At present, a single large-scale deep-water cage can be cultured. 10 to 50 tons of finished live fish, so when the fish is grown, the live fish must be caught and sold in a timely manner to ensure the economic benefits of farming, but such a large number of finished live fish must be collected and maintained at a high survival rate. Because there is no suitable fast and efficient mechanized fishing equipment, fishing is a big problem. At present, only artificial fishing can be used, or crane-type equipment and hanging baskets can be used to fish. The speed is slow for a long time, and the mechanical damage to the fish is also great, resulting in a high mortality rate of live fish, which will seriously affect the economic benefits of aquaculture. Problems to be solved urgently in the chemical aquaculture industry.

The upper end of the pipe is located on the upper side of the net skin, the lower end of the fish-discharging pipe is located on the lower side of the mesh skin, and the lower end of the fish-discharging pipe is provided with a fish-discharging valve, and the outer wall of the connecting portion is also provided with an annular air bag, so the The annular air bag is located between the limiting groove 1 and the floating body, the annular air bag is communicated with an air pump through an air supply pipeline, and the air pump is fixed on the floating body, and the light fish attracting device includes a solar panel, a battery and several water bottles. The lower fish-collecting light, a battery box is arranged on the upper end face of the floating body, the battery is arranged in the battery box, the solar panel is arranged on the upper end of the floating body, and several underwater fish-collecting lights are evenly arranged in the row. On the edge of the upper end of the fish tube, the solar panel is electrically connected to the battery through a wire, and the underwater fish-collecting lamp is electrically connected to the battery through a wire.

The fish discharge valve in the breeding cage is connected with the suction port of the fish suction pipe of the vacuum fish suction pump, and the fish in the breeding cage is directly sucked out into the container for storing the fish through the vacuum fish suction pump.

An annular air bag is arranged between the limiting groove 1 on the outer wall of the connecting part and the floating body. The annular air bag is communicated with the air pump fixed on the floating body through the air supply pipeline, and gas is injected into the annular air bag through the air pump, so that the The rise of the position promotes the fish to move to the bottom of the aquaculture cage, that is, the fish in the aquaculture cage gathers to the upper end of the fish discharge pipe, which increases the density of the fish in the unit water body, thereby improving the fish suction efficiency of the fish suction pump.

Several underwater fish collecting lights are evenly arranged on the edge of the upper end of the fish draining tube, because the upper end of the fish draining tube is located at the bottom of the breeding cage, so when the underwater fish collecting lights glow, the phototaxis of the fish is used to attract the fish to the aquaculture. The bottom of the cage, that is, the fish in the aquaculture cage is gathered to the upper end of the fish discharge pipe through the underwater fish collecting lamp, which increases the density of the fish in the unit water body, thereby improving the fish suction efficiency of the fish suction pump.
