a breeding cage

technical field

The invention belongs to the technical field of breeding equipment, and relates to a breeding net cage.

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.

In the above-mentioned culture cage, the cross-sectional shape of the blade is a right-angled triangle.

The blade is in a right-angled triangle, forming a small upper and lower large space in the connecting part, and a funnel-shaped vortex is generated after the rotation of the blade, which improves the fish suction efficiency of the fish suction pump.

In the above-mentioned breeding cage, the arc-shaped baffles are arranged obliquely, and when the arc-shaped baffles rotate, the driving ring has an upward movement trend. When the arc-shaped baffle is rotated, it can drive the connecting part to move upward, so that the fish can move to the bottom of the breeding cage.

In the above-mentioned breeding cage, the drive ring is made of plastic or wood. The drive ring is made of lightweight material, it has a certain buoyancy in the water, it does not need to be fixed when it is not rotating, and it is more conducive to floating when it is rotating.

Compared with the prior art, the breeding cage has the following advantages:

1. Through the cooperation of the high-pressure nozzle, the driving ring and the spinner, the water in the connecting part can be stirred to rotate to form a vortex, which in turn drives the water in the net sleeve to gradually rotate to form a vortex, so that the fish in the aquaculture cage can move toward the net. The bottom of the box can improve the density of fish in the unit water body and improve the fish suction efficiency of the fish suction pump.
