What kind of fish can be kept in deep sea cages?

Using the research methods of fish ecology, fish behavior and aquaculture, the behavior habits of several deep-water cage cultured fish were observed, and the results showed that the tolerance to dry dew was black sea bream, red sea bream, sea bass, American red fish and large yellow croaker. Large yellow croaker is evenly distributed in the middle and lower cage edges, clusters, and no fighting, American red fish is evenly distributed in the middle and lower layers, clusters, and fierce fighting, sea bass is evenly distributed in the middle and lower layers, less clusters, and fierce fighting, and true sea bream is distributed in the lower and lower cage edges, less clusters, and fights, and black sea bream is distributed in the lower and lower cage edges, less clusters, and fighting; The feeding rhythm is obvious, which is related to the rise and fall of the tide, and forms two feeding peaks during the flat tide or stop tide time near the morning and evening. Different feeding methods had an effect on the feeding intensity of fish, and the tolerance to hunger increased with the decrease of water temperature. The average daily feeding rate was the highest in July and August, and the lowest in February, indicating that the feeding rate of fish was closely related to water temperature. The diurnal activity habit is not obvious, and it is distributed at the bottom of the cage or the edge of the downstream cage when the flow is rapid, and the activity distribution range is significantly expanded when the flow is slow. The strength of the ability to resist wind, waves and currents is American red fish, sea bass, large yellow croaker, black sea bream, and red sea bream. deep-water cages; large yellow croaker; American Redfish; Sea bass; red sea bream; black sea bream; Behavioral habits.

The so-called deep-sea cages, is used in the sea area, the fish raised must have a certain resistance, so far China's deep-sea cages of fish include American red fish, black catfish, red sea bream, grouper, sea bass, six-line fish, cobia, salmon, golden pomfret and so on. If necessary, you can contact Qingdao Skoli Marine Technology****, which can provide equipment and technology such as deep-sea cages, floating cages, etc.

Deep-sea wind and wave resistant cage with frame structure style.

One. A floating deep-sea wind-resistant circular cage with a circumference of 40 meters. The appearance of this cage frame is perfectly circular, which is made of hot melt welding of the main floating pipe of the inner and outer rings, handrail column pipes, tees, positioning blocks, pins and other main and auxiliary accessories, and the materials are all made of new high-density polyethylene raw materials and anti-aging agents one-time injection molding.

The diameter of the main floating pipe is 250mm, the diameter of the handrail is 110mm, the height of the column is 80cm, the circumference of the box is 40 meters, the diameter is 13 meters, the aquaculture water body can reach 2000 cubic meters, the wave height is more than 7 meters, and it can resist typhoons above 10 levels.

2. Floating deep-sea wind-resistant circular cage with a circumference of 60 meters. The frame elements and materials of this cage are the same as those of the floating circular cage with a circumference of 40 meters. The difference is that this kind of cage adopts the main floating pipe with a pipe diameter of 315mm, and the circumference is 60 meters, and the water area is doubled compared with the original main floating pipe box with a diameter of 250mm.

Its breeding capacity is stronger and the utilization rate is higher.

Cage culture: A production method in which cages made of mesh are placed in a certain area of water for fish farming. The cages are mostly set up in lakes, rivers, reservoirs and other waters with a certain water flow, fresh water quality and high dissolved oxygen content.

High-density intensive culture can be implemented, and the output per square meter can reach more than ten to dozens of kilograms according to the bottom area of the cage. It mainly breeds carp, non-crucian carp, rainbow trout, etc., and China also raises silver carp, bighead carp, grass carp and bream. Mesh (mesh) is made of synthetic fibers or wires, etc.

It is better to have a rectangular box. Each cage has an area of tens of square meters and a box height of 2-4 meters. There are three types of setting methods: floating, fixed and sinking, and the floating type is used more.
