Description
Technical Field
The invention belongs to the field of aquaculture and ocean resource development, and particularly relates to a composite net cage for deep and distant sea fish culture, which is used for supporting the expansion of the net cage culture of marine fishes to deep and distant sea.
Background
The large-scale mariculture is concentrated in a narrow space range of a shallow water sea area near the shore, and a series of problems such as industrial conflict, ecological loss, disease risk, quality safety and the like are caused. Therefore, the expansion of mariculture from near shore to offshore and deep open sea has become a necessary choice for the development of mariculture industry in China.
In order to meet the requirement of offshore culture, High Density Polyethylene (HDPE) circular floating deepwater net cages, lifting circular net cages, disc-shaped deepwater net cages and other types are developed successively by some units at home and abroad. In recent years, China also successfully develops a floating net cage and a lifting type wind wave resistant net cage with reinforced structures, so that the net cage for fish culture in China has certain typhoon resistance, and the safety of net cage culture near the bank in China is ensured to a certain extent. However, the existing deepwater wind wave resistant net cages in China cannot be used for carrying out cultivation activities far away from the coast, and the problems of energy supply and automatic feeding of net cage cultivation are not solved, so that certain problems exist in structural strength.
The Wu-boat re-worker builds a semi-submersible net cage in a deep sea fishing ground for Norway and can be used for offshore culture production of salmon in high latitude and low temperature sea areas. However, because the water temperature of the upper layer of the sea area in China is high in summer and large offensive sharks exist in open sea, the cage cannot be used for culture of salmon. In addition, the net cage fishing and net washing device is very complicated, has higher manufacturing cost and provides non-green energy.
Recently, China oceanic university and Wu-Hui ship are in heavy work cooperation, and a 'dark blue No. 1' fully-submerged large net cage is designed and built. The net cage can sink into the yellow sea cold water mass in high temperature season, and float upwards on the upper layer of the water body to culture salmon in other seasons. However, the net cage needs to be matched with a semi-submersible energy source and a feeding platform to develop culture production. Because the net cage and the semi-submersible platform are provided with independent buoyancy systems and anchoring systems, the net cage occupies a large sea area during production and has high facility cost. The research and development of a fish culture net cage, green energy supply, automatic bait feeding and other integrated composite net cage structure is an urgent need for the development of the deep sea aquaculture industry.
