Description
Technical Field
The invention belongs to the technical field of deep sea cage culture, and particularly relates to a device for protecting fish and generating power by using a deep sea culture cage.
Background
With the improvement of living standard, people have more and more demands on marine products, and have higher and higher requirements on the quality of the marine products. However, due to the national restrictions on the marine environment and resources and the fishing amount, the traditional fishing industry has already reached a saturation state, so that the development of aquaculture has become a necessary trend.
The deep sea net cage is a net cage for cultivating fish in deep and distant sea areas (the sea surface depth is 50-70 m), and the net cage has a large space inside, so that the cultivated fish has a wide moving range and inhabitation space; and the water body in the net cage is large, and the inhabitation space of the fishes is closer to the natural environment. With the return of high profit of the cultured deep-sea fish species and the high-speed development of cage technology, the development scale of deep-sea culture is rapidly enlarged, the demand of deep-sea culture cages is more and more, and deep-sea cage culture is one of the main modes of seawater culture.
When the surrounding of the deep sea net cage is calm or is less influenced by wind and waves, the fishes cultured in the existing deep sea net cage can inhabit in a wide space, so that the survival rate of the fishes is high, the growth is fast, the fish diseases are few, the fishes are easy to recover, and the body shape and the meat quality of the fishes are closer to the wild.
The device comprises a deep sea net cage, a plurality of metal net walls and a plurality of water outlets, wherein the deep sea net cage is internally provided with a closed space, and the inner wall of the net cage is a metal net wall surface; even if the fishes always keep moving in a reverse flow manner to avoid colliding the net cage, the long-time reverse flow movement also causes the fishes to consume excessive energy, the normal growth of the fishes is influenced, the growth cycle is prolonged, and the quality and the culture yield of the cultured fishes are reduced. Therefore, the economic benefit of the existing deep sea cage culture can be reduced under the wind and wave environment.
Because the influence degree of the surge is smaller the deeper the depth below the sea surface is, one of the methods for avoiding the influence of the large-scale wind wave and even the typhoon by the existing deep-sea net cage is as follows: the deep sea net cage is submerged to a certain depth below the sea level so as to reduce the influence of surging, but the deep sea net cage can be realized only by consuming a large amount of energy, and the deep sea net cage is very large in size, so that the process of controlling the net cage to ascend and descend is difficult, and the implementation cost of the method is high and the difficulty is high.
Based on the above problems, if a device is designed and installed in the deep sea net cage, when the deep sea net cage is influenced by large storms or even typhoons, the device can greatly reduce the impact of water flow on cultured fishes in the deep sea net cage, so that a safe inhabitation space can be provided for the fishes, the fishes are effectively prevented from impacting the inner wall of the net cage, the damage rate and the death rate of the cultured fishes are reduced, the culture yield is improved, the economic benefit of net cage culture is increased, and the device has a large practical application value.
