Aquaculture cages are corrosion-resistant and easy to manage
The advantages of cage culture:
(1) It can save the land and labor required for excavating fish ponds and loach ponds, and the investment will pay off quickly. Generally, the full cost of raising loach and fish can be recovered in the same year, and the cage can be used continuously for 2-3 years under normal circumstances.
(2) Cage culture of loach and fish can make full use of water bodies and erbium feed organisms, and implement polyculture, intensive culture, and high survival rate, which can achieve the purpose of creating high yields.
(3) The feeding cycle is short, the management is convenient, and it has the advantages of flexibility and easy operation. The cage can be moved at any time according to the changes of the water environment conditions. In case of waterlogging, the net height can be raised without being affected. In case of drought, the net position can be moved without loss. .
(4) Easy to catch. No special fishing tools are required when harvesting, and it can be marketed at one time, or it can be caught in stages and batches according to market needs, which is convenient for live fish transportation and storage, and is conducive to market regulation. The masses call it “live fish” on the water.
(5) Strong adaptability and easy to promote. Cage loach and fish farming occupy a small area of water, and as long as there is a certain water level and flow, they can be raised in rural areas, factories and mines.
(6) It is conducive to aquatic respiration. This is also because of the benefits of water flow. The flow of water brings sufficient dissolved oxygen. If the water in the pond is changed, the water in the cage will also change with the water level, and after the water change, the water in the cage will be the same as if the water was changed. Sufficient fresh water can bring sufficient dissolved oxygen to aquatic products.
(7) It is beneficial to keep the inside of the cage clean. Since the cage has many small holes, when feeding, if there is too much bait to be eaten, part of the bait will flow out of the cage through the small holes, avoiding more accumulation in the cage. , which is beneficial to the aquatic products inside.
(8) It is convenient to check the growth of water production by yourself. Especially in special circumstances, such as when there is a disease or when the weather changes drastically, people can directly lift a part of the bottom of the cage to check the health of the water production inside.
