Effective Pre-Stocking Pond Bottom Preparation: A Case Study
Effective pre-stocking pond bottom preparation is key to successful aquaculture. This article examines a case study of a shrimp pond that successfully reduced disease risk using Biosolution's Pond Bottom Preparation Formula.
Effective Pre-Stocking Pond Bottom Preparation: A Case Study of a Successful Shrimp Pond
Effective pre-stocking pond bottom preparation is a crucial step in the aquaculture cycle. Many farmers fail early by neglecting this stage, leaving fry vulnerable to stress and disease. This article presents a case study of a shrimp pond in East Java that increased productivity by up to 30% by implementing proper pond bottom preparation, including the use of Biosolution's Pond Bottom Preparation Formula.
Why Is Pre-Stocking Pond Bottom Preparation So Important?
Ponds or shrimp ponds that have just been harvested leave behind a lot of organic waste such as feed, feces, and dead plankton. If not managed, this organic matter will decompose anaerobically, producing toxic compounds like ammonia (NH₃), nitrite (NO₂⁻), and hydrogen sulfide (H₂S). This condition leads to poor water quality, suppresses the fry's immune system, and triggers disease outbreaks such as vibriosis or white feces disease.
Effective pre-stocking pond bottom preparation aims to:
- Decompose organic waste aerobically
- Stabilize pond bottom pH
- Reduce pathogenic bacteria populations
- Provide an optimal environment for fry growth
Case Study: Vaname Shrimp Pond in Situbondo
Mr. Budi, a vaname shrimp farmer in Situbondo, suffered consecutive losses due to high fry mortality rates (30-40%) in the first week. Diagnosis showed pond bottom ammonia levels reached 2 ppm and unstable pH (6.2-8.5). He then adopted the pond bottom preparation protocol recommended by Biosolution.
Preparation Steps Taken
- Total drying of the pond for 7 days until cracks appeared.
- Liming with dolomite at 2 tons/hectare to raise bottom pH.
- Application of Pond Bottom Preparation Formula (5 L/hectare) containing Bacillus subtilis and Thiobacillus sp., spread evenly while the pond was still dry.
- Water filling to a height of 10 cm and left for 3 days for bacterial activation.
- Full filling and initial fertilization with probiotics.
Results Achieved
- Bottom ammonia levels dropped to <0.1 ppm
- pH stabilized in the range of 7.5-8.0
- Fry survival rate increased to 95%
- Stocking density could be increased from 100 to 150 shrimp/m²
Role of Microbes in the Pond Bottom Preparation Formula
The Pond Bottom Preparation Formula contains two superior bacteria: Bacillus subtilis and Thiobacillus sp., along with extracellular enzymes. Bacillus subtilis acts as the main decomposer, breaking down proteins, fats, and complex carbohydrates into simple compounds. Thiobacillus sp. plays a role in sulfide oxidation and pH stabilization, thereby suppressing foul odors and H₂S toxins. Extracellular enzymes accelerate the decomposition process, making pond preparation shorter.
How to Apply the Pond Bottom Preparation Formula
Application is done once during the pond drying stage. A dose of 5 L per hectare is dissolved in clean water (1:10) then sprayed or spread evenly on the pond bottom. The best time is in the morning, before fry stocking. Ensure the pond is dry so that bacteria can colonize well.
Benefits of Using the Pond Bottom Preparation Formula
- Clean start to the cultivation cycle: Low organic load from the beginning.
- Reduces early disease attacks: Environment does not support pathogen growth.
- Safer higher stocking density: Water quality maintained even at high densities.
- Recurring purchase every cycle: This product becomes a routine need.
Conclusion
Effective pre-stocking pond bottom preparation is an initial investment that determines the success of aquaculture. Mr. Budi's case study proves that with a scientific approach and biotechnology products like the Pond Bottom Preparation Formula, fry mortality risk can be drastically reduced.

FAQ
1. What is meant by pre-stocking pond bottom preparation?
Pre-stocking pond bottom preparation is a series of actions to clean, decompose organic waste, and stabilize pond bottom conditions before fry are stocked. The goal is to create a healthy and optimal environment for fry growth.
2. When is the best time to apply the Pond Bottom Preparation Formula?
The best time is in the morning when the pond is dry after drying, about 3-5 days before fry stocking. This gives time for bacteria to colonize and work.
3. Is the Pond Bottom Preparation Formula safe for fry?
Very safe because it contains natural probiotic bacteria that are not pathogenic. This product actually suppresses harmful bacteria and improves water quality, making fry healthier.
4. What dosage is needed for a 5000 m² pond?
The dosage for a 5000 m² (0.5 hectare) pond is 2.5 L. Mix with clean water at a 1:10 ratio and apply evenly.
5. Can this product be used for brackish water ponds?
Yes, the Pond Bottom Preparation Formula is suitable for both freshwater and brackish water. The Thiobacillus sp. content is effective at stabilizing pH across various salinities.
