Introduction Of Fish Cage

Deep-water cages, also called offshore cages, are large-scale cages with a water depth of more than 15 meters and open coastal waters.

Deepwater cage culture has a large capacity and is a marine breeding facility with strong resistance to wind and waves and ocean currents. Deepwater cages are expanding breeding

It has shown obvious advantages in sea areas, alleviating coastal environmental pressures, improving the quality of farmed fish, and increasing the benefits of farming.

At present, the types of net cages in the world include floating net cages, lifting net cages, sunken net cages and semi-submerged net cages according to different operating methods.

Depending on the structure of the cage, there are round, square, polygonal and tapered. The material of the frame is also plastic, metal and concrete.

The same form. In recent years, HDPE (High Density Polyethylene) is used as the raw material for cages worldwide.

What stresses fish out in a fish cage

Some of the most common causes of fish stress in aquariums include: Elevated ammonia and nitrate levels due to infrequent water changes, which is the main cause of stressed goldfish. pH fluctuation due to the exhaustion of mineral buffers. Fluctuations in water temperature, which is the main cause of stressed Betta.

What size should openings be in fish cage to prevent king fisher from getting fish

So, be sure to use material with openings of 1.5 by 1.5 centimetres. This is the right size to keep in the smaller fish and also to let fresh water through.cage and fish.

Advantage

1、 Corrosion resistance

Polyethylene pipe (PE pipe) is an inert material, which can resist the corrosion of various chemical media, without electrochemical corrosion, without anti-corrosion coating, and can be used in all water areas.

2、 Good hygiene

PE pipe processing does not add heavy metal salt stabilizer, no scaling, no bacteria, no water pollution.

3、 Long service life of pipeline

Mortar wear test shows that the wear resistance of PE pipe is more than 4 times of that of steel pipe, and its service life can be more than 50 years.

4、 Reliable connectivity

The strength of the joint is higher than that of the base metal itself.

5、 Convenient and fast construction

The quality of pipeline is light, the welding process is simple, the construction is convenient, the construction time of hot-melt connection is greatly reduced, and the comprehensive cost is low.

6、 Beautiful

There are two kinds of fish world cage, square and round, mainly black blue stripe PE pipe. The pipe fittings are orange and black, which have a sharp contrast with the water surface, and the visual appearance is beautiful and atmospheric.
