TECHNICAL FIELD

[0001] The utility model relates to the field of aquaculture, and particularly relates to a mandarin fish domestication net cage. BACKGROUND

[0002] Mandarin fish is very sensitive to changes in living environment. Significant changes in water body have a very significant impact on the breeding of mandarin fish. Some important water parameters, such as water temperature, pH, salt concentration, and minerals and trace elements, should not fluctuate or change greatly for a long time. Sudden changes in these parameters will cause an impact on mandarin fish, which will cause mandarin fish to be sick or die. Therefore, the mandarin fish is domesticated through the domestication net cage. The domestication net cage is used in the breeding pond. The existing domestication net cage directly discharges the excrement of the mandarin fish into the breeding pond, which pollutes the water body of the breeding pond. Meanwhile, it is inconvenient to clean the excrement. SUMMARY

[0003] Therefore, the utility model aims at providing a mandarin fish domestication net cage. The excrement of the mandarin fish is filtered and enters the second cavity and then adheres to the suction accessories, so as to avoid the excrement of the mandarin fish from being directly discharged into the breeding pond and reduce the pollution of the water body of the breeding pond.

[0004] In order to solve the above technical problems, the utility model uses the following technical scheme:

[0019] By setting up filter screens, mandarin fish of different sizes can be separated, improving the domestication effect of mandarin fish; at the same time, multiple filter screens are arranged along the length of the first cavity, and the aperture gradually decreases along the distribution direction; by cooperating with the hanging device, the horizontal state of the net cage body is changed, thereby achieving the separation of mandarin fish of different sizes; after tilting the net cage body, the mandarin fish swim from one end of the net cage body to the other end under the action of gravity, while multiple filter screens block the mandarin fish of different sizes in turn, so that the mandarin fish of different sizes are contained in different cavities respectively.

[0020] The removable filter screen makes it convenient to use; this allows the filter screen to be installed only when it is necessary to separate mandarin fish of different sizes, and to screen out mandarin fish of different sizes in a timely manner at different stages of domestication.

[0021] This invention utilizes filtration to block the mandarin fish, allowing the mandarin fish's excrement to pass through the filter and enter the second chamber, where it adheres to the adsorption element. This prevents the mandarin fish's excrement from being directly discharged into the aquaculture pond, thus reducing water pollution in the aquaculture pond. Attached Figure Description
