Abstract

The invention discloses a culture net cage with a high degree of cleanliness and a method thereof, comprising a net frame, a cylindrical main net arranged on the net frame with an upper end opening, a fixing plate arranged in the soil layer below the bottom surface of the main net, The column on the fixed plate that passes through the bottom of the main net, the upper net mechanism and the lower net mechanism on the lower part of the column; there is a tension spring between the lower net mechanism and the fixed plate, and a cylinder is installed on the fixed plate , the telescopic rod of the cylinder is in contact with the lower net mechanism; it also includes a cylindrical auxiliary net located at the upper end of the main net. The mesh size of the auxiliary net is smaller than the size of the feed particles. The mechanism is connected with several lower retractors arranged at the lower part of the net frame. The invention has the characteristics that the area under the net cage can be automatically cleaned to ensure no eutrophication around the net cage and effectively improve the utilization rate of the feed.

Description

technical field [0001] The invention relates to the technical field of cages, in particular to a breeding cage and a method with high cleanliness. Background technique [0002] With the development of the aquaculture industry, cage culture has become more and more popular. Cage fish culture is a highly intensive breeding method that applies intensive pond culture technology to larger water surfaces with superior environmental conditions to achieve high yields. It can save the land and labor required for excavating fish ponds, and the results are quick after investment. Cage fish farming can make full use of water bodies and erbium feed organisms, and implement polyculture and close culture. , easy to manage, flexible and easy to operate. However, because the water flow is flowing, sometimes the flow is fast, when feeding feed to the cage, the feed is easy to flow out of the cage, and some fish only eat the feed in the water. The feed at the bottom of the box will be mixed w...
