Anti wind and wave deep-water net cage refers to a large net cage with a breeding capacity of over 1500 cubic meters set in deeper waters above 15 meters, which has strong wind resistance, wave resistance, and ocean current resistance. It generally consists of four parts: frame, netting, anchoring, accessories, etc. Lift type deepwater net cage, also equipped with lifting facilities.

Deep sea net cages are mainly composed of frame systems, net bags, fixed systems, and supporting facilities. By utilizing the interaction of fixed platforms and the characteristics of the box, the box is lowered to a limited depth underwater. Due to the exponential decay of wave intensity with increasing water depth, the wave intensity at the location of the net box at a certain depth will also decrease exponentially, in order to achieve the purpose of resisting wind and waves.
One Floating deep-sea anti wind and wave circular net cage with a circumference of 40 meters
　　
The cage frame is round in appearance, and is made of main and auxiliary accessories such as inner and outer ring main floating pipes, handrail column pipes, tees, positioning blocks, pins, etc. by hot-melt welding. All materials are made of new high-density polyethylene raw materials and anti-aging agent by one-time injection molding. The main floating pipe diameter is 250mm, the handrail diameter is 110mm, the column height is 80cm, the box circumference is 40 meters, the diameter is 13 meters, the aquaculture water body can reach 2000 cubic meters, the anti wave height is over 7 meters, and it can withstand typhoons of level 10 or above. [2]
2、 A floating deep-sea anti wind and wave circular net cage with a circumference of 60 meters.
　　
The frame components and materials of this type of net cage are the same as those of a floating circular net cage with a circumference of 40 meters. The difference is that this type of net cage uses a main floating pipe with a diameter of 315mm and a circumference of 60 meters, which doubles the water area compared to the original main floating pipe box with a diameter of 250mm. Its breeding capacity is stronger and its utilization rate is higher.
3、 Lifting deep-sea anti wind and wave circular net cage with a circumference of 40 meters and 60 meters
The appearance, size, and materials of this type of net cage are basically the same as those of floating net cages, but an additional lifting function is added in the design and installation. When a typhoon approaches, sinking the net cage to a safe water layer at a certain depth underwater can more effectively avoid the damage of large waves and strong typhoons to the net cage, thereby better protecting the safety of the box and farmed fish.
4、 2 * 2 combination square net cage with an area of 5 × 5 meters
The so-called combination type square net cage is composed of multiple single mouth net cages, each single mouth box is 5 meters long and 5 meters wide, with a square appearance, a main floating pipe diameter of 250mm, a handrail diameter of 110mm, and a column height of 80cm. 2 * 2 combination means that each group of net cages is composed of four single mouth boxes symmetrically arranged, with a length of 12 meters per group. Due to its combination, each container has a relatively small area, making it aesthetically pleasing, suitable, and easy to operate. Therefore, it is suitable for diversified aquaculture in coastal areas and can also be used for leisure and entertainment facilities. [3]
5、 Diversity combination square net cage
Composite square boxes are made up of combinations, so each set of boxes can be combined in a variety of ways, such as 5 × 5 meters of 2 * 3 composite square boxes, 3 * 3 composite square boxes, etc...

 
The types of net cages are divided into closed and open types based on the assembly method of the box body and the presence or absence of a cover net. Closed net cages are generally used for breeding filter feeding fish or setting up net cages in areas with strong winds and waves, as well as on water surfaces that require overwintering; In waters with less wind and waves, open net cages are generally used for breeding edible fish or fish species. Divided by the shape of the net cage, there are rectangles, squares, polygons, and circles; According to the method of setting up the net cage, there are three types: fixed, floating, and sinking.
Floating cage
Adopting the most widely used setting method. Compared to fixed net cages, net cages can be suspended on buoyancy devices or frames, floating with changes in water level, and their effective volume will not change due to changes in water level. This installation method is mainly suitable for reservoirs and lakes with deeper water bodies and less wind and waves. Due to the high ground clearance of the net cage, it can also be transferred to aquaculture sites, which relatively reduces water pollution caused by fish feces and residual bait, thus maintaining good water quality conditions at all times. Floating net cages have poor resistance to wind and waves, so it is advisable to add a cover net.
This type of net cage can move freely, and a part of the net body (net cover) is floated to the surface using a float and net cage frame. Even if the water level changes, the depth of the net body remains unchanged. As long as the net cage is not muddy, the water volume of fish cultured in the net cage remains constant. Due to the free movement of the net cage, the water quality inside the net cage is better than that of a fixed net cage. This type of net cage is suitable for installation in deeper reservoirs and lakes, and is currently the most widely used type of net cage.

Fish row style net cage is made of rubber fish rows, made into a grid shape, and used for aquaculture by tying nets in the grid. Due to the large area and good flexibility of rubber fishing rafts, they are not only resistant to wind and waves, easy to operate, have a long service life, high survival rate in aquaculture, low cost, but also environmentally friendly and non polluting. The use of fish row net cage aquaculture technology can not only increase fishermen's access to wealth, but also replace intertidal pond aquaculture and protect the coastal environment.
