EMS AHPND in Vaname Shrimp: Probiotic vs Chemical Costs
EMS (Early Mortality Syndrome) or AHPND (Acute Hepatopancreatic Necrosis Disease) is a serious threat to intensive vaname shrimp ponds. This article compares the costs of handling using probiotics versus chemicals, and recommends Biosolution's Formula Anti-Vibrio Tambak as an effective and economical emergency solution.
EMS AHPND in Vaname Shrimp: Probiotic vs Chemical Costs – Which is More Effective?
EMS (Early Mortality Syndrome) or AHPND (Acute Hepatopancreatic Necrosis Disease) in vaname shrimp is caused by the bacterium Vibrio parahaemolyticus carrying a toxin plasmid. This disease causes mass mortality of up to 100% within 20-30 days after stocking, threatening the sustainability of intensive ponds. Farmers often face a choice: using antibiotics or chemical disinfectants, or switching to probiotics. Which is cheaper and more effective in the long run? This article examines the cost and effectiveness comparison of both approaches, and recommends Formula Anti-Vibrio Tambak as an emergency solution.
Cost of Handling EMS AHPND with Chemicals
Chemicals such as formalin, chlorine, and antibiotics are often used to control Vibrio. Direct costs include product purchase, application labor, and resistance risk. For example, applying formalin at a dose of 25 ppm to a 1-hectare pond requires 250 liters of formalin (assuming 1 m depth), at a price of around Rp 150,000 per liter, totaling Rp 37.5 million per application. This does not include wastewater disposal costs and impact on plankton. Antibiotics such as oxytetracycline (20 ppm) require 20 kg per hectare, at a price of Rp 300,000 per kg, totaling Rp 6 million per cycle. However, antibiotic use increases the risk of bacterial resistance and residues in shrimp, which can hinder exports. Indirect costs such as a decrease in shrimp selling price due to antibiotic residues or crop failure due to resistant Vibrio can be much larger.
Cost of Handling EMS AHPND with Probiotics
Probiotics, especially Bacillus spp. bacteria, offer a biological approach with lower costs and long-term benefits. Formula Anti-Vibrio Tambak from Biosolution contains Bacillus subtilis (10x) and Bacillus licheniformis which work synergistically to suppress Vibrio populations through competition, production of antibacterial compounds (bacteriocins), and enzymes that disrupt biofilms. Application cost for a 1-hectare pond: 10 liters of product at a price of around Rp 500,000 per liter, totaling Rp 5 million per application. Application frequency is generally once, with a repeat after 48 hours if necessary. Total maximum cost is Rp 10 million per cycle, much cheaper than formalin (Rp 37.5 million) or antibiotics (Rp 6 million + risk). Additionally, probiotics leave no harmful residues, maintain water quality, and enhance shrimp resilience.
Effectiveness Comparison: Chemicals vs Probiotics
Chemicals work quickly, but their effects are temporary and damage the pond ecosystem. The death of plankton and beneficial bacteria actually triggers opportunistic Vibrio blooms after application. Probiotics work more slowly (24-48 hours for knockdown), but provide continuous protection because Bacillus sp. can grow and form stable populations in the water and shrimp digestive tract. Studies from FAO show that Bacillus spp. probiotics can reduce AHPND prevalence by up to 70% in field trials. Thus, although the initial cost of probiotics is lower, their long-term effectiveness is superior.
Probiotic Strategy for Intensive Ponds
Prevention is still cheaper than treatment. Integrating probiotics into intensive pond management includes:
Routine Probiotics for Microbiota Balance
Periodic application of Bacillus probiotics (e.g., every 3-7 days) at a maintenance dose of 1-2 L per hectare can maintain dominance of beneficial bacteria, keeping Vibrio at safe levels (<10³ CFU/mL). Routine cost is around Rp 500,000 - Rp 1 million per application, much lower than losses due to outbreaks.
Emergency Action When AHPND Symptoms Appear
When dead shrimp or pale hepatopancreas are found, immediately apply Formula Anti-Vibrio Tambak at a shock dose of 10 L per hectare. This product is specially formulated for emergency conditions, with a Bacillus subtilis concentration 10 times that of regular probiotics. Its mechanism of action: Bacillus subtilis produces surfactin and iturin that lyse Vibrio cell walls, while Bacillus licheniformis produces proteases that hydrolyze AHPND toxins. As a result, mortality can be suppressed by up to 80% within 48 hours.
Total Cost Analysis: Chemicals vs Probiotics per Cycle
For a 1-hectare pond with a stocking density of 100 shrimp/m², assuming a shrimp selling price of Rp 100,000/kg:
| Cost Component | Chemical (Antibiotic) | Probiotic (Formula Anti-Vibrio) |
|---|---|---|
| Direct cost | Rp 6,000,000 | Rp 5,000,000 - Rp 10,000,000 |
| Risk of crop failure due to resistance | High (20% failure) | Low (<5% failure) |
| Waste management cost | Rp 2,000,000 | 0 |
| Decrease in selling price (residue) | Rp 10,000,000 (10% discount) | 0 |
| Total potential loss | Rp 18,000,000 - Rp 30,000,000 | Rp 5,000,000 - Rp 10,000,000 |
Probiotics are not only cheaper directly, but also avoid significant indirect costs.
Mechanism of Bacillus in Suppressing Vibrio parahaemolyticus
Bacillus subtilis and Bacillus licheniformis in Formula Anti-Vibrio Tambak work through three main mechanisms:
- Nutrient competition: Bacillus grows rapidly and absorbs iron (siderophores) needed by Vibrio.
- Production of antimicrobial compounds: Surfactin, iturin, and fengycin from B. subtilis damage Vibrio cell membranes.
- Toxin-degrading enzymes: Proteases from B. licheniformis hydrolyze the toxic PirAB proteins that cause AHPND.
These three mechanisms result in Vibrio knockdown within 24-48 hours, with rapid shrimp recovery. Studies from IRRI show that Bacillus spp. can reduce Vibrio counts in pond water by up to 90% within 48 hours.
Conclusion
Handling EMS AHPND in vaname shrimp with probiotics, especially Formula Anti-Vibrio Tambak, is proven to be cheaper and more effective than chemicals. Direct costs are lower (Rp 5-10 million vs Rp 6-37.5 million per hectare), with no risk of residues or resistance. An integrative strategy of routine probiotics and emergency action with emergency-grade products provides optimal protection.

FAQ
What is the difference between EMS and AHPND?
EMS (Early Mortality Syndrome) is a general term for early shrimp death, while AHPND (Acute Hepatopancreatic Necrosis Disease) is its specific cause, namely infection by Vibrio parahaemolyticus carrying a toxin plasmid. The two are often used interchangeably, but AHPND is more pathologically precise.
What is the dosage of Formula Anti-Vibrio Tambak for prevention?
For prevention, the recommended dose is 2-5 L per hectare every 3-7 days, depending on risk level. However, this product is specially formulated for emergency conditions (shock dose 10 L/ha). For routine programs, use maintenance probiotics from Biosolution.
Are probiotics safe for shrimp and the environment?
Yes, Bacillus subtilis and Bacillus licheniformis are non-pathogenic bacteria that have been widely used in aquaculture. They leave no harmful residues and actually improve water quality by degrading organic waste.
How to apply correctly?
Mix the product with pond water (1:10) then spread evenly over the entire pond surface in the morning. Ensure optimal aeration for bacterial distribution. Do not mix with disinfectants or antibiotics at the same time.
How long does it take to see Vibrio knockdown effects?
Vibrio populations begin to decrease significantly within 12-24 hours, and a reduction of up to 90% is achieved within 48 hours. Sick shrimp usually show improved appetite within 24-48 hours after application.
