Like any other structure, the polyethylene fish breeding cage has various types that are used according to the geographical location as well as environmental and weather conditions.

In general, this type of structure is divided into 3 main types: fixed, floating and submerged.

In the following, we will give a brief explanation about each of the above cases.

Fixed type fish breeding cage:

The fixed type of fish farming is such that special nets with a special mesh radius are thrown into the water of the lake, river, etc. In order to fix these nets, poles are installed in the water bed, which are kept stable by these poles with special net equipment.

This structure is used in shallow areas, because special poles must be installed to keep the nets stable.

Breeding fish in this type of structures has little cost because the steps to do it are easily done and also its design is not a difficult task.

Floating type of fish breeding cage:

Breeding fish in these floating environments is also another common method. In this bed, special nets with special mesh sizes are used.

A series of polyethylene pipes that are bent and form a hollow circle are installed around this net. These pipes are placed on each other by the base of polyethylene cages.

In the seabed, special clamps are used to keep fluid transfer pipes afloat. In fact, the polyethylene floating clip is placed on both sides of the pipe and keeps it on the surface of the water so that water and chemicals can be transferred properly.

It should be noted that in order to prevent the fish-eating birds from eating the fish inside the net, special nets are also installed in the upper part of these structures so that these fish do not become food for the birds.

Among the advantages of using this type of bed, we can point out the ability to design in various shapes, as well as the possibility of installation in areas with great depth and stormy conditions.

In addition, the cost of repairing this structure is much lower than other types.
