Shrimp Growing Slowly in Ponds? Here's the Probiotic Solution

Slow shrimp growth in ponds is a classic problem that harms vaname farmers. Suboptimal growth extends the harvest cycle, increases feed costs, and reduces productivity. The causes are diverse, ranging from poor water quality, pathogenic bacterial attacks such as Vibrio, to improper feed management. However, probiotic-based solutions have now proven effective in overcoming this problem. This article will technically discuss how to apply the Vaname Shrimp Pond Probiotic Formula to improve shrimp growth and pond water quality.

Why Do Shrimp Grow Slowly in Ponds?

Slow shrimp growth can be caused by several interrelated factors. First, poor water quality, especially high levels of ammonia and nitrite, inhibits shrimp metabolism. High ammonia (>0.1 ppm) is toxic and disrupts oxygen absorption, causing shrimp stress and decreased appetite. Second, the presence of pathogenic Vibrio bacteria causes infections in the hepatopancreas and digestive tract, disrupting digestion and nutrient absorption. Third, unstable plankton populations affect oxygen supply and natural feed. Fourth, excessive feed management actually increases organic load and triggers the growth of pathogenic bacteria. Fifth, genetic factors and excessively high stocking density also contribute. Understanding these causes is important for determining the right handling strategy, one of which is probiotic application.

The Role of Probiotics in Overcoming Slow Shrimp Growth

Probiotics are live microorganisms that provide health benefits to the host, in this case shrimp. In ponds, probiotics work through several mechanisms: (1) competitive exclusion of pathogenic bacteria, (2) production of antimicrobial compounds, (3) decomposition of organic matter, (4) more efficient nitrogen cycling. By suppressing Vibrio and maintaining water quality, probiotics create an optimal environment for shrimp to grow. Biosolution's Vaname Shrimp Pond Probiotic Formula contains four superior strains: Bacillus subtilis, Bacillus licheniformis, Nitrosomonas sp., and Nitrobacter sp.. Bacillus subtilis and Bacillus licheniformis produce extracellular enzymes that break down organic waste, while Nitrosomonas and Nitrobacter oxidize ammonia into nitrite and nitrate, keeping ammonia concentrations below 0.1 ppm. This combination not only accelerates shrimp growth but also increases survival rate (SR) by 10–15%.

Probiotic Formula Application: Dosage, Frequency, and Right Timing

Dosage per Hectare

The recommended dosage is 5 liters per hectare of pond. This dosage applies to intensive ponds with a stocking density of 100–200 shrimp/m². For semi-intensive ponds, the dosage can be adjusted to 3–4 L/ha. It is important to accurately measure the pond water volume for precise dosing. Dilution with fresh water before broadcasting can help even distribution. Do not mix probiotics with chlorine or other disinfectants at the same time.

Application Frequency

The application frequency is every 7–10 days during the cultivation period. At the beginning of the cycle (first week), more frequent application (every 7 days) is recommended to build up beneficial bacterial populations. After the population stabilizes, the frequency can be extended to 10 days. Routine water quality monitoring (ammonia, nitrite, pH) helps determine if the frequency needs adjustment. If ammonia levels start to rise, application can be accelerated to every 5–7 days.

Application Timing

The best time is morning or late afternoon when water temperature is not too hot (25–30°C). Avoid application during scorching sun because UV rays can kill probiotic bacteria. Ensure aeration is on during and after application to distribute probiotics evenly and provide oxygen for aerobic bacteria. If the pond uses a circulation system, turn off circulation momentarily so probiotics are not immediately flushed out.

Step-by-Step Application Guide

Here is a practical guide for direct broadcast probiotic application:

1. Preparation: Calculate pond water volume (length x width x average depth). Prepare probiotics according to dosage (5 L/ha).
2. Dilution: Mix probiotics with fresh water at a 1:10 ratio (e.g., 5 L probiotics + 50 L water) in a clean container. Stir gently.
3. Broadcasting: Sprinkle the solution evenly over the entire pond surface, especially in aeration and feeding areas.
4. Aeration: Ensure aeration runs for at least 30 minutes after application.
5. Monitoring: Record application time and measure water quality every 3 days.

Expected results: Vibrio population drops by up to 40%, ammonia stabilizes below 0.1 ppm, and water exchange needs reduce by 30%. Shrimp will show increased appetite within 3–5 days after application.

Case Study: Probiotic Effectiveness in Vaname Ponds

A study in intensive vaname ponds in East Java showed that routine application of the Vaname Shrimp Pond Probiotic Formula resulted in an SR of 85% compared to the control's 72% (a 13% increase). Average ammonia was 0.08 ppm, far below the threshold. Vibrio population in water decreased from 10³ CFU/mL to 6×10² CFU/mL. Farmers also reported water exchange cost savings of up to 30%. This data aligns with product claims supported by field trials. For optimal results, combine with good feed management and standard stocking density.

Conclusion

Slow shrimp growth in ponds can be overcome with proper probiotic application. Biosolution's Vaname Shrimp Pond Probiotic Formula, with a combination of Bacillus subtilis, Bacillus licheniformis, Nitrosomonas sp., and Nitrobacter sp., can suppress Vibrio, maintain stable ammonia, and increase SR by 10–15%. Application of 5 L/ha every 7–10 days in the morning or late afternoon is key to success.

FAQ

Q: Are probiotics safe for shrimp? A: Yes, probiotics contain non-pathogenic bacteria that are safe for shrimp and the environment. The strains used have been tested and cause no side effects. Follow the recommended dosage.

Q: Can probiotics be mixed with vitamins or minerals? A: It is best not to mix them directly in one container as it can affect bacterial viability. Administer separately with at least a 2-hour interval.

Q: Do I need to reduce feed when using probiotics? A: No, probiotics actually aid digestion so feed can be utilized more efficiently. However, continue feed management based on feeding trays.

Q: What if ammonia remains high after application? A: Recheck dosage and frequency. If necessary, increase frequency to every 5 days until ammonia drops. Ensure adequate aeration and that organic load is not excessive.

Q: Can probiotics be used for semi-intensive ponds? A: Yes, at a dosage of 3–4 L/ha and frequency of 10–14 days. Adjust according to pond conditions and water monitoring results.
