Abstract

The invention discloses a one-way streaming cage, which comprises a bracket, wherein the middle part of the side surface of the bracket is provided with a cantilever which is connected in a rectangular way and can limit the inside space of the bracket; the side surface of the bracket is also provided with inflating pipes which are distributed from top to bottom; the side surface of the bracket is connected with a streaming device; a netting is suspended at the inner side of the bracket, and the lower part of the netting is arranged outside the bracket; the lower end of the netting is connected with a sinker; and the part of the bracket which has the streaming device is connected with an anchoring rope through the distribution device. The streaming device always performs the streaming towards the water flow, so the acting force of the water flow on the netting can be reduced, valid culture water inside the netting can be further increased, and the culture capacity can be increased. The netting can be adequately unfolded by the inflating pipes and the cantilever, and the streaming device is coupled, so the culture capacity of the netting is basically maintained stable. After water is filled inside the inflating pipes, the entire device is sunken into the water, so an effect on preventing the wave force can be played. The one-way streaming cage has advantages of high streaming efficiency, good wave-resistant and water flow resistant effect and large and stable valid culture capacity.

Description

technical field

[0001] The invention relates to a breeding device, in particular to a one-way shunting cage. Background technique

[0002] As a traditional farming method, shallow water cage culture is mainly concentrated in semi-enclosed bays. Affected by economic interests, the density of shallow-water cage culture in some coastal areas of China is relatively high, resulting in poor water flow and severe hypoxia in some cultured water bodies. In addition, residual bait and fish excrement cannot be quickly transported out with the water body, resulting in the environmental capacity of the cultured water body. The overload phenomenon is serious. This farming method not only pollutes the water quality of sea areas, but also affects the quality of farmed fish, and has also become one of the main factors that induce coastal red tides. Therefore, it is the only way for the sustainable development of cage culture to gradually transfer the cage culture from the inner bay and off...
