Vannamei Shrimp Pond Vibriosis: How to Apply Anti-Vibrio Formula (Emergency)

Vibriosis in intensive vannamei shrimp ponds is a scourge that often causes crop failure. Vibrio spp. bacterial attacks can trigger mass mortality within days. Therefore, fast and precise treatment is essential. Biosolution's Anti-Vibrio Formula for Vannamei Shrimp Ponds (Emergency) is a knockdown solution with proven dosage and application methods. This article will discuss in detail how to apply this product, from dosage per hectare, frequency, to the best application time.

Why Vibriosis is a Serious Threat in Intensive Ponds?

Intensive vannamei shrimp ponds have high density, artificial feed, and accumulation of organic matter that become a fertile medium for pathogenic Vibrio such as Vibrio harveyi and Vibrio parahaemolyticus. These bacteria can cause diseases like Acute Hepatopancreatic Necrosis Disease (AHPND) and general vibriosis characterized by pale hepatopancreas, necrosis, and sudden death.

In intensive systems, oxidative stress and decreased shrimp immunity worsen the infection. The use of synthetic antibiotics is often ineffective due to resistance and harmful residues. Therefore, a probiotic approach with antagonistic bacteria such as Bacillus subtilis and Bacillus licheniformis is the primary choice. The Anti-Vibrio Pond Formula (Emergency) is specifically designed to rapidly suppress Vibrio populations through competition mechanisms and production of antibiosis compounds.

Composition and Mechanism of Action of Anti-Vibrio Pond Formula

The Anti-Vibrio Formula for Vannamei Shrimp Ponds (Emergency) contains two superior probiotic bacterial strains:

Bacillus subtilis (10x)

This strain is developed at a very high concentration (10 times that of regular probiotics) to provide a knockdown effect. Bacillus subtilis produces various extracellular enzymes such as protease, lipase, and chitinase that degrade Vibrio cell walls. Additionally, this bacterium produces peptide antibiotics like subtilin and surfactin that are bactericidal against Vibrio.

Bacillus licheniformis

This strain is known as a strong enzyme producer and antibiosis compound. Bacillus licheniformis also produces lichenysin, an antimicrobial peptide effective against gram-negative Vibrio. The combination creates synergy: Bacillus subtilis works quickly to suppress populations, while Bacillus licheniformis cleans up residual organic matter that serves as hiding places for Vibrio.

Both are non-pathogenic and safe for shrimp and the environment. Competitive exclusion also occurs, where probiotics dominate space and nutrients, preventing Vibrio from thriving.

Dosage and Application Method of Anti-Vibrio Pond Formula (Emergency)

Dosage: 10 Liters per Hectare

This dosage is a shock treatment designed to significantly suppress Vibrio populations in a short time. For ponds with high severity (e.g., shrimp starting to show symptoms), the dosage can be increased to 12-15 L per hectare upon technical recommendation. Ensure the product is fresh and homogeneous before use.

Application Method: Direct Broadcast into the Pond

This product is ready to use and does not need to be diluted. Broadcast evenly over the entire pond surface. Application should preferably be done in the morning (06:00-08:00) when water temperature is still low and dissolved oxygen is high. These conditions support probiotic bacterial activity and reduce stress on shrimp. Avoid application during rain or extreme weather.

Frequency: Single Application, Repeat After 48 Hours If Needed

In emergency conditions, a single application is sufficient to reduce Vibrio populations by up to 90% within 24-48 hours. If after 48 hours symptoms are still present or Vibrio test results remain high, reapplication can be done at the same dosage. Do not exceed 3 consecutive applications without consulting Biosolution's technical team.

Best Application Time: Morning

Morning is the most ideal time because:

• Water temperature is lower (28-30°C) so probiotics do not die quickly.
• Dissolved oxygen is high due to phytoplankton photosynthesis.
• Shrimp are more active and can absorb probiotics through the digestive tract.
• Evaporation is low, keeping probiotic concentration stable.

If application must be done during the day, ensure aeration is increased to maintain dissolved oxygen.

Tips for Successful Anti-Vibrio Formula Application

1. Stop feeding 2-4 hours before application to reduce organic load and increase probiotic effectiveness.
2. Ensure aeration is running optimally during and after application to maintain probiotic distribution and oxygen.
3. Monitor Vibrio using TCBS media before and 48 hours after application to evaluate effectiveness.
4. Do not mix with disinfectants or antibiotics simultaneously as they can kill probiotics. Allow a minimum 24-hour interval.
5. Store the product in a cool place (4-10°C) to maintain bacterial viability.

Comparison with Conventional Methods

The Anti-Vibrio Emergency Formula provides speed equivalent to antibiotics without side effects. This is an ideal solution for intensive ponds prioritizing sustainability.

Case Study: Effectiveness in Intensive Ponds

In an intensive vannamei pond in Lampung with an area of 1 hectare, Vibrio levels rose to 10⁴ CFU/mL at week 60 of cultivation. Shrimp showed feeding pause and pale hepatopancreas. After application of Anti-Vibrio Formula 10 L/ha, within 48 hours Vibrio populations dropped to 10² CFU/mL, and shrimp appetite returned to normal. No additional mortality occurred. The farmer then continued with Vannamei Shrimp Pond Probiotic Formula to maintain microbial balance until harvest.

Advantages of Using Biosolution's Anti-Vibrio Emergency Formula

• Rapid Vibrio knockdown: High concentration of Bacillus subtilis (10x) ensures drastic reduction within 24-48 hours.
• Prevents mass mortality: By suppressing pathogens, shrimp have time to recover immunity.
• Fast recovery: The combination of Bacillus licheniformis helps clean organic matter and improve water quality.
• Premium emergency grade: Specifically designed for emergency conditions with measured dosage.
• No residue: Safe for shrimp, environment, and consumers.
