The king of water color-brown water

Aquaculture water is the living environment of aquatic animals, and the quality of water has a decisive influence on the success or failure of aquaculture. So what kind of water color can maximize the economic benefits of shrimp farming?

First of all, good water color is essential!
Brown, dark brown, that is, diatom water. It is one of the best water colors in aquaculture. The water quality is "fat, live and cool" with moderate fertilizer. The algae in the water are diatoms, such as: hornhair algae, crescent rhombus algae, triangular brown finger algae, etc., these algae are shrimp larvae excellent bait; in addition to the oxygen production capacity of the round sieve algae, Navicula and so on.

The water phase of diatoms is more colorful than other water, and the breeding objects living in this environment have better vitality, smooth body color, good food digestion and absorption, and fast growth rate. And diatoms have benthic habits, can oxidize the bottom, decomposition of the bottom of the residual bait feces, which is the ability of other algae do not have. Diatoms have a long life cycle, and once cultured, it is not easy to turn water to algae compared to other water colors. The importance of stable water color for aquaculture is self-evident. Diatom is more tolerant to low temperature, its most suitable growth temperature is 15-30 ℃, and it can still grow normally at 4-35 ℃. Diatom is still very advantageous in low temperature environment. advantages of diatoms, can be summarized

1. Control the accumulation of ammonia nitrogen and nitrite nitrogen: diatoms like to live in the middle and lower layers of water bodies, bringing sufficient dissolved oxygen to the middle and lower layers of aquaculture water bodies and reducing the production of toxic and harmful substances such as ammonia nitrogen, nitrite and hydrogen sulfide;

2. Rich nutrition: diatom contains a large number of vitamins, polysaccharides, trace elements, amino acids, DHA active substances, etc., is the seedling stage of high-quality natural bait;

3. Oxygen production capacity is stronger: diatoms contain weak light protein, can produce more, more durable oxygen;

4. Inhibition of Vibrio: diatom fatty acids contain Vibrio suppression factor, can inhibit Vibrio;

5. It is easy to form population advantage: after diatoms are cultivated and occupy the water space, problems such as moss and cyanobacteria will not appear;

6. Stable water temperature: water quality rich in diatoms, water temperature is relatively stable, not easy to cause stress response to breeding objects, conducive to growth.

7. Diatoms are easy to lack in general water because of their different nutrient elements. After diatoms multiply, they should be fertilized in time, otherwise they are easy to pour algae. Diatom reproduction needs silicate components, so in the process of fertilizer hydroponic algae, it is necessary to regularly supplement the silicate required for diatom growth, such as diatom Wang, rich in inorganic salts required for diatom, scientific ratio, directional cultivation of diatom, regular use of water stability.

Compared with green algae, the water purification ability of diatoms is relatively weak, so some green algae can be cultivated appropriately to improve the water purification ability of water body. Super algae species, super concentration process and dormancy treatment are used regularly to ensure the activity and can be preserved for a long time.
