A round table type anti-wind and wave net cage

Abstract

The invention provides a round table type anti-storm net cage, which belongs to the technical field of aquaculture, and comprises a net cage frame and a net. The top of the net is connected with the net cage frame. There is a sewage collection component, and a dispersion plate is arranged under the sewage collection component, and both the sewage collection component and the dispersion plate are connected with the netting. The net cage of the present invention can realize the self-balancing ups and downs of the net cage, has strong wind and wave resistance, and at the same time ensures the water body exchange speed inside and outside the net cage, avoids eutrophication in sea areas and the occurrence of fish diseases, and effectively improves the breeding environment , to promote the growth of aquatic products.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a round platform type anti-storm net cage. Background technique [0002] Conventionally, when the net cage is arranged in an inner bay where the flow velocity is slow, there is a problem that the residue of the bait fed into the net cage settles on the bottom of the sea and turns into sludge to cause marine pollution. In addition, in closed waters like the inner bay where there is little water replacement, it is easy to infect fish with diseases. In particular, in recent years, elements such as nitrogen and phosphorus contained in household or factory drainage have flowed into the sea, causing eutrophication (sea water), and red tides on the sea surface have adversely affected marine products. Moreover, when a large number of fish are cultured in the limited space in the bay, the cages have to be densely arranged, and there is a risk of fish death due to insuffic...

AI Technical Summary

Problems solved by technology

Moreover, when a large number of fish are cultured in the limited space in the bay, the cages have to be densely arranged, and there is a risk of fish death due to insufficient dissolved oxygen in the water.

And when strong winds such as typhoons, because the net cage frame floating on the sea surface is directly subjected to the influence of strong wave undulation or fast current that strong wind etc. produce, thereby produce net cage drifting, damage, even because the net cage is broken and makes water The product runs away, causing large damage

On the other hand, when the net cages are arranged in the open sea in order not to pollute the ocean or have no impact on aquatic products, the net cages are always directly affected by strong wave fluctuations or fast currents, which are easily damaged and highly dangerous. Therefore, it is more difficult to set up the cages in the open sea
