Pre-Stocking Pond Bottom Preparation: Dosage, Frequency, and Application Timing Guide

Pre-stocking pond bottom preparation is a crucial step that determines the success of a shrimp or fish farming cycle. Without optimal preparation, the risk of early disease outbreaks, water quality deterioration, and seed mortality increases dramatically. This article thoroughly discusses how to apply the Pond Bottom Preparation Formula from Biosolution, including dosage per hectare, frequency, and best timing to achieve maximum results.

Why Is Pre-Stocking Pond Bottom Preparation So Important?

Pre-stocking pond bottom preparation aims to create an optimal environment for seeds before stocking. This process includes drying, liming, and bottom remediation. However, what is often overlooked is the application of decomposer microbes to accelerate the breakdown of organic residues and stabilize pH. Residual feed, feces, and dead plankton from the previous cycle can become sources of ammonia and pathogens if not managed properly. By using the Pond Bottom Preparation Formula containing Bacillus subtilis and Thiobacillus sp., you can ensure a clean pond bottom, stable pH, and readiness for seed stocking.

Dangers of Untreated Organic Residues

Organic residues that accumulate on the pond bottom undergo anaerobic decomposition, producing toxic compounds such as ammonia (NH3) and hydrogen sulfide (H2S). This condition stresses seeds, lowers immunity, and opens the door for infection by pathogenic bacteria like Vibrio spp. Therefore, rapid aerobic decomposition is essential.

Composition of the Pond Bottom Preparation Formula: Superior Microbes

The Pond Bottom Preparation Formula contains three active components that work synergistically:

• Bacillus subtilis: A gram-positive bacterium that produces protease, amylase, and lipase enzymes to break down proteins, carbohydrates, and fats from organic residues.
• Thiobacillus sp.: A sulfur-oxidizing bacterium that helps stabilize pH by converting sulfide compounds into non-toxic sulfates.
• Extracellular enzymes: Accelerate the decomposition reaction, making the pond bottom cleaning process more efficient.

This combination ensures that the farming cycle starts from a clean and balanced environment.

Proper Application Method: Dosage, Frequency, and Timing

For effectiveness, the application of the Pond Bottom Preparation Formula must follow these guidelines:

Dosage Per Hectare

The recommended dosage is 5 liters per hectare. Do not reduce it as it will decrease decomposition effectiveness. For small ponds, adjust proportionally. For example, for a 0.5-hectare pond, use 2.5 liters.

Application Frequency

Once per cycle is sufficient. No repetition is needed because the microbes will multiply and work for several days. However, if the pond is very dirty (e.g., lots of black sludge), you can repeat the application at a dose of 3 L/ha after 3 days.

Application Timing

Apply in the morning when water temperature is still low (25-30°C) to avoid stressing the microbes. Spread evenly over the entire pond surface that has been dried and filled with water to a depth of 10-20 cm. Let it sit for 3-5 days before raising the water to normal level and stocking seeds.

Application Method

1. Dry the pond until the bottom cracks.
2. Fill with water to a depth of 10-20 cm.
3. Spread the Pond Bottom Preparation Formula evenly.
4. Leave for 3-5 days without aeration.
5. Raise the water to normal level (80-100 cm) and stock seeds.

Benefits of Proper Application

By following the above guidelines, you will experience the following benefits:

• Clean start to the farming cycle: No foul odors or gas bubbles from the pond bottom.
• Reduced early disease outbreaks: Healthier seeds due to a pathogen-free environment.
• Safer stocking density: You can increase stocking density by 10-15% without high mortality risk.
• Recurring purchase: Because it is effective, farmers tend to buy again every cycle.

Case Study: Application in Vaname Shrimp Ponds

A farmer in Lampung applied the Pond Bottom Preparation Formula to a 1-hectare pond at a dose of 5 L. After 4 days, the pond bottom appeared clean, no black sludge, and water pH was stable at 7.5-8.0. Vaname shrimp seeds were stocked at a density of 120 shrimp/m². As a result, the survival rate (SR) reached 85% in the first week, higher than the previous cycle which was only 70%.

Conclusion

Effective pre-stocking pond bottom preparation is an initial investment that determines farming success. By using the Pond Bottom Preparation Formula from Biosolution, you get a microbiology-based solution that is safe, easy to apply, and proven to improve pond environmental quality. Follow the dosage of 5 L/ha, apply in the morning, and let it sit for 3-5 days before stocking. For further consultation, contact our technical team via WhatsApp.

FAQ

1. Is the Pond Bottom Preparation Formula safe for shrimp or fish seeds?

Yes, this product uses natural microbes that are not pathogenic. Bacillus subtilis and Thiobacillus sp. are safe for aquatic organisms and actually help suppress the growth of harmful bacteria.

2. How long after application should I wait before stocking seeds?

It is recommended to wait 3-5 days after application for the microbes to work optimally and water conditions to stabilize. You can monitor water parameters such as pH, ammonia, and nitrite before stocking.

3. Do I need to repeat the application if it rains?

If heavy rain occurs immediately after application, you may need to repeat with half the dose (2.5 L/ha) because microbes could be washed away. However, if it is light rain, no need.

4. Can this product be used for clay ponds?

Certainly. This product is effective on various soil types, including clay. Make sure the pond is dried well so that microbes can work on the bottom.

5. Where can I buy the Pond Bottom Preparation Formula?

The product is available at authorized Biosolution distributors or through online orders. For more information, contact us on WhatsApp.
