I don't know if you know that the water quality of the pond for aquaculture is sometimes turbid, and the water body is unstable due to poor water quality, which leads to weak self-regulation ability and has a great impact on aquaculture. Therefore, if you want to solve the problem of aquatic safety, you need to solve the problem fundamentally, that is, water quality! This article learned about the causes of muddy water quality from the Internet, and took this opportunity to share it with you!
1. Physical reasons:
1.Due to rainfall, more soil flows into the pond, resulting in higher turbidity of the pond water quality.
2.The lack of organic matter at the bottom of the pond results in less nutrients in the water quality, the growth of algae is difficult, and the agitation of the aerator is easy to cause turbidity in the water body.
3.The installation structure of the aerator is unreasonable, most of which is due to the microporous aeration equipment, the installation height of the aeration plate is too small, resulting in the aeration pipe being too close to the bottom sediment of the water body, which is easy to lead to the suspension of pollutants at the bottom and cause turbidity of the water body;
4.Once it rains heavily, due to the large change in the temperature of the upper and lower layers of the water body, the water body produces a strong density flow, and the sediment at the bottom layer turns up with the density flow, and is suspended in the water, and the mud will soon be formed;
2. Biological causes:
1.The breeding range is too large, especially the breeding density is too large, the agitation of organisms will lead to the suspension of organic matter in the water, the transparency of the aquaculture water is low, the water is turbid, the light transmittance is very low, and the water is difficult to fertilize;
2.The native zooplankton in the water body is abundant, and the zooplankton will ingest phytoplankton (algae), resulting in a large decrease in algae, and the water body loses a large number of algae and becomes turbid.
3.Nutrient imbalance in water bodies. Algae species nutrients that are partially deficient in nutrients due to the imbalance of nutrients in the water body, and it is difficult to form a good water color; This results in turbidity;
4.After sterilization and disinfection, destroying the water bacteria and supplementing the beneficial bacteria in time will also cause turbidity, because the lack of bacteria to decompose organic matter, so it leads to too much suspended organic matter in the water body and causes the water body to become turbid;
5.Insufficient feeding will also cause turbidity, which will cause turbidity about 5 meters along the edge of the water body, and there will be no turbidity in the center of the pond, which can be solved directly by increasing the amount of feeding;
6.In the case of aquatic products with parasites on the surface of the body, there will be a phenomenon of swimming, and in serious cases, fish clusters will swim and cause local turbidity in the water body, which needs to be carefully inspected and treated with targeted drugs.
