The yellow sea cold water mass is positioned at the deep layer and the bottom of the middle sea area of the yellow sea in China, the water temperature is low in summer, the water quality is good, the sea area is about 13 kilo square kilometers, the water volume is 5000 billion cubic meters, and the yellow sea cold water mass can be used for breeding cold water ocean economic species such as salmon and trout. In 2018, the first full-submersible type deep and open sea aquaculture net cage 'dark blue No. 1' in the world is independently developed and built in China, and at present, a layered (thermocline-crossing) net cage 'dark blue No. 2' is built and used for carrying out yellow sea cold water mass salmon and trout aquaculture so as to expand the mariculture space in China and promote the development of the deep and open sea aquaculture industry in China.
In summer, the vertical distribution difference of the water temperature in the yellow sea area is large. When the surface water temperature rises to a temperature which cannot meet the requirement of the cultured object, the fish need to submerge into a deep cold water area, or the net cage is settled to a low-temperature water layer, so that the survival temperature of the cultured object is guaranteed. However, it is difficult to catch the fish cultured in the deep water layer after the fish submerge or the net cage subside in summer. The technique and the device for catching the cultured fishes by the giant net cages of the ocean fishing ground No. 1 in Norway adopt the technique of mechanically driving the gathered fishes and then mechanically catching the cultured fishes. Practice has proved that the device is easy to fail under the conditions of easy corrosion and high sea conditions, and influences the fishing and production plan with strong timeliness. At present, the mode of batch fishing of deep-water layer fishes in the sea is mainly a bottom trawl, fishes cultured in a common net cage are mainly caught by a purse net and the like, and the fishes cultured in the deep layer of a large net cage have no simple and reliable catching technology and device.
