Improvement of Substratum Quality in Culture Ponds of Penaeus vannamei

Water quality mutations are mainly caused by sediment pollution, especially in the middle and later stages of shrimp farming. Some shrimp ponds use low-quality compound feed, causing a large amount of organic matter in the shrimp ponds to be deposited and rot and decompose under the action of bacteria, which consumes a lot of oxygen and produces harmful poisons such as hydrogen sulfide. Therefore, it is necessary to regularly use (10 to 15 days) the use of bottom modified drugs, commonly used are: zeolite powder, dolomite powder, lime, photosynthetic bacteria, beneficial microbial agents. Among these medicines, lime is the most commonly used and there are three types of lime used for cultivation:

1, agricultural lime

Mainly limestone crushed derived, the main component is calcium sulfate, algae can be a stable source of calcium, pH buffer effect, is very suitable for use in high-level pool. It has a good effect on stabilizing water quality.

2, hydrated lime

Limestone is produced by high temperature firing and has a certain influence on the pH. When the pH is higher than 7.5, it should not be used.

3, quicklime

When it is fired at high temperature, water is added to react to form calcium hydroxide, which can quickly dissolve the bacterial protein membrane, causing it to lose its vitality, and it has the functions of bactericidal and neutralizing the acid toxicity in the pool. When calcium hydroxide encounters carbon dioxide, it turns into calcium carbonate, which is a better seawater buffer that regulates the pH of seawater. To prevent the use of quicklime when pH has a greater impact, do not use it during the feeding process. The use of lime is generally based on the following principles:

(1) When the pH is greater than 7.9, change the water and add agricultural lime.

(2) When the pH fluctuation in the day is greater than 0.5, add lime for agricultural use after changing the water.

(3) When the pH is less than 7.5, add slaked lime after changing the water.

(4) When there is foam on the surface of the water, use agricultural lime after changing the water.

(5) When the water color changes, change the water and add agricultural lime.

(6) The amount of lime is generally 15 to 20 mg/l.

The pH is measured every day from 7:00 to 8:00 and from 16:00 to 17:00, and the daily variation is generally within 0.5. The pH is lower than 7.8, which can be adjusted by using slaked lime powder or dolomite powder; if it is higher than 9.0, it can be regulated by combining disinfection, changing of water, dolomite powder and heterotrophic beneficial microorganism preparations.

From 7:00 to 8:00, bottom layer water samples were used to determine ammonia nitrogen, nitrite nitrogen, hydrogen sulfide, and dissolved oxygen. Dissolved oxygen should be kept above 4.0 mg/l. If the dissolved oxygen content is low, it should be regulated by adjusting fresh water, changing water, increasing the number of aerators or starting time. The total ammonia nitrogen content is higher than 0.5 mg/L, and the nitrite nitrogen content is higher than 0.10 mg/L. It should be regulated by adjusting the water color, changing the water and sewage, applying zeolite powder or using beneficial microorganisms, etc. to maintain good water quality.


LRIS-NLS is a device that displays and measures oscillation of frequencies from 1.4 t0 5.0 giga-hertz. The signals are sent to the Cerebral Cortex via the infrared LED technology, it now travels the Cerebral Cortex to be picked up and amplified by magnetic conductors within the device. This signal is sent back through a special trigger sensor within the LRIS-NLS box, which must be transferred now to digital sequence by a microprocessor within the LRIS-LS and than communicated to your computer. It is then processed into non-linear stems analysis (NLS). All data is recorded and compared to [normal" Etalons of the base information to compare for the Pathology of its client and shows as a magnetically signal or Bio resonance.

Vector 8D NLS

What is NLS device?
The principles of the NLS Device have their origins in bioresonance research that started in the 1950`s by scientists in the USA and Russia. Since that time, hundreds of millions of dollars have been channeled into testing and improving the technology to its current levels of excellence. The database that lies at the heart of the NLS contains exclusive information resulting from Russian developers examining and treating over 100,000 patients with over 1,000 health issues".

8D Lris Nls Function:

1. Fear.
2. Emotional.
3. Relationship.
4. It has AURA function which can show our weakness energy of our organ.
5. The most important thing is it can be used to check the bacteria,pathological, allergen analysis, microbes and parasites.

6. Biochemical dynamic level.
7. Homeopathy.
8. Most suitable and not suitable for foods.
9. Flower essences.

10. Unbalanced organ analysis.
11. Gemstone energy.
12. Herbs, etc.
13. Sample data library. So it can test the food allergy and suggest indications of the effect of the nutritional products.
