How to judge the quality of water and how to deal with it

In the whole process of river shrimp cultivation, the quality of water is a very important factor to determine the yield of river shrimp per mu. Now let's learn how to judge water quality.

The quality of water as long as the quality of fertilizer, live, tender, cool. Of course, the most important key factor depends on the water quality of oxygen capacity is not high. Good water quality is conducive to the growth of river shrimp, reducing the incidence of river shrimp and hypoxic floating head phenomenon.

First of all, the Fat

The degree of water quality depends mainly on the transparency and color of water quality. Good water quality transparency is generally maintained at 15-500px. So how to regulate the water quality of the degree of obesity, what factors affect the water quality of obesity?

It is very easy to affect the transparency of the water body if the water body is not disinfected or injected with new water for a long time. Excessive transparency of water quality will affect the intake and body color of river shrimp, reduce the growth rate of river shrimp and increase the incidence of river shrimp.

When the transparency of too much fertilizer is low, the water body is easy to grow cyanobacteria, especially in the summer when high temperature is very easy to break out cyanobacteria phenomenon. Over - fertilized water quality will make river shrimp feed floating to the surface of the water, resulting in a waste of feed.

Second, the Live

Water capacity of oxygen directly affect the growth rate of river shrimp, when oxygen is lower than 3.5 mg/L, river shrimp can appear hypoxic hypoxia in, the water capacity of oxygen below 5 mg/L, river shrimp growth rate will become very slowly, under the water quality, river shrimp food intake again big, the river shrimp growth speed will be very slow, the best oxygen capacity is above 7.5 mg/L.

Third , Tender

The color that observes water body with naked eye, good water quality color is tea green commonly, of course not be other color is water quality becomes bad certainly. Good water quality is early qing shuiwan is green commonly, look at in the morning that is to say more qing shuiqing, what can change to afternoon water color is greener, look more fat. But it is not cyanobacteria phenomenon of fat, as if green tea water as the kind of cool fat.

Iv . Clear

Good water quality, it looks like living, fat but not greasy, moderate transparency looks very cool, once the water is greasy, the intake of river shrimp will decline, if the water is greasy in winter, then river shrimp is very easy to grow ciliates.

How to judge the quality of water and oxygen content in water? We can use the simplest soil method, with an empty transparent mineral water bottle, it is full of water in the pond (the bottle is completely immersed in water to irrigate water, prevent air from entering) under the sun for about 10 minutes, if there are small bubbles in the bottle, then the oxygen capacity in the water is relatively high. We can also judge the quality of water by observing the water in the bottle. If there is precipitation and stratification in the water in the bottle, it indicates that the water quality is not very ideal, and you need to adjust it. Good water quality has no precipitation and stratification.

So if the water quality is not clean, the bottom of the black mud, smelly mud, how to maintain the water quality and transparency? At this time we can use holy frog brand aquaculture special disinfectant and reagent. Disinfectant can disinfect the water body, reduce the production of bacteria in the water, and protect the growth environment of river shrimp. The modifier can decompose hydrogen sulfide, toxic amines and other harmful substances at the bottom of the mud, and make the soil return to the light yellow and soft before.
