Aquaculture net cage

Abstract

The invention relates to the technical field of aquaculture, and discloses an aquaculture net cage. The aquaculture net cage comprises a first net cage body and a second net cage body; inserting rods are fixedly connected to the corners of the lower ends of the first net cage body and the second net cage body, an oxygenation device is installed at the front end of the first net cage body, and a purification device is arranged inside the first net cage body; a lifting device is arranged at one end of the purification device inside the second net cage body, a connecting mechanism is installed at the joint of the first net cage body and the second net cage body, a separation mechanism is detachably connected to one side of the second net cage body in one end of the first net cage body, and a second opening is formed in one side of the separation mechanism at one end of the second net cage body; and the first net cage body and the second net cage body are both made of corrosion-resistant metal materials. According to the aquaculture net cage, fishes of different sizes can be cultured separately, food deposition is prevented from affecting water quality, the content of oxygen in water can be increased, manual fishing is not needed, and labor is saved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture net cage. Background technique [0002] In the previous cages, only the nets were opened in the water with floats and sinkers, and the nets were suspended in the water. This kind of simple cages were mostly not used. With the development of the times, the methods of cages are different now. The hexahedral frame can be made of metal, wood or moso bamboo. After the overall frame is installed, it has a strong ability to resist wind and waves in water. If there is a lack of oxygen in the box, it is very convenient to move the net cage as a whole. It is also very convenient to eliminate attachments on net clothes, but it is troublesome to carry. The frame of the net cage is also made of a flat square frame, and then equipped with floats and sinkers to suspend the net in the water. This kind of net net drying net cage is very simple and easy to carry It's also very ...

Problems solved by technology

[0005] The existing culture net cages have some disadvantages. First, some larger fish such as snakehead and catfish in the same cage will eat fry, which is not conducive to the growth of fry. Secondly, the fluidity of the water in still water is poor, and the oxygen content in the water is reduced. , the fish will appear hypoxic, and the unfinished food will be deposited in the cage, affecting the water quality in the cage. In addition, manual fishing is required, which is inefficient and very troublesome. Therefore, we propose an aquaculture Cage
