Description

Technical Field

[0001] The utility model relates to the field of water filtering devices, in particular to a circulating water filtering device for breeding of carp. Background Art

[0002] The water for mackerel farming needs to be filtered for the following important reasons:

[0003] 1. Removes impurities and waste:

[0004] During the breeding process, mackerel produces waste such as feces and uneaten feed. If not filtered, these impurities will accumulate in the water, causing water quality to deteriorate. For example, excessive feces will decompose to produce harmful substances such as ammonia nitrogen and nitrite, posing a threat to the health of fish.

[0005] 2. Maintain good water quality parameters:

[0006] Filtration can help keep water parameters such as pH, hardness, and dissolved oxygen within an appropriate range; a stable water quality environment is conducive to the growth and reproduction of mackerel; for example, if there is insufficient dissolved oxygen in the water, mackerel may have difficulty breathing and slow growth.

[0007] 3. Control harmful microorganisms and pathogens:

[0008] Unfiltered water may contain a variety of harmful microorganisms and pathogens, such as bacteria, viruses and parasites; filtration can reduce their numbers and reduce the risk of disease infection for mackerel;

[0009] 4. Improve water transparency:

[0010] Clear, transparent water is helpful for observing the health and behavior of the fish; if the water is too turbid, it may mask the symptoms of the fish's disease and delay treatment;

[0011] In short, filtering the water for the cultivation of mackerel is one of the key measures to ensure its healthy growth and improve the efficiency of cultivation;

[0012] What problems can be caused by high water temperature in mackerel farming in summer?

[0013] When filtering the aquaculture water of black carp through the filter plate, especially in summer, the aquaculture water of black carp cannot be cooled down. As the water temperature rises, the dissolved oxygen content in the water will decrease; black carp may face hypoxia, affecting its normal physiological function and reducing the survival rate of black carp.
