WHAT ARE AQUATIC PROBIOTICS? BENEFITS, USAGE GUIDELINES, AND TIPS FOR CHOOSING EFFECTIVE PRODUCTS
In recent years, aquaculture has been growing rapidly, especially intensive farming models for shrimp and fish with high stocking densities.
However, increased production also brings many challenges, such as water pollution, organic matter accumulation, toxic gas formation, and the risk of disease outbreaks.
To address these challenges, many farmers have chosen to use aquatic probiotics as a safe, effective, and environmentally friendly biological solution.
These products are considered an important tool for maintaining a stable pond ecosystem, improving aquatic animal health, and increasing production efficiency.
What Are Aquatic Probiotics?
Aquatic probiotics are biological products containing selected beneficial microorganisms that support water treatment, organic matter decomposition, and the balance of microbial communities in aquaculture systems.
Common microorganisms found in aquatic probiotic products include:
- Bacillus bacteria: Capable of breaking down organic matter, leftover feed, and waste materials in ponds.
- Lactobacillus bacteria: Help balance intestinal microflora and improve digestion in aquatic animals.
- Nitrosomonas and Nitrobacter bacteria: Participate in nitrogen compound conversion, helping reduce the toxicity of NH3 and NO2.
- Saccharomyces yeast: Supports organic matter decomposition and improves digestive function.
Unlike chemical treatments used in aquaculture, aquatic probiotics work through natural biological processes, helping maintain long-term environmental stability without negatively affecting shrimp, fish, or the surrounding ecosystem.
Why Should Aquatic Probiotics Be Used in Aquaculture?
In intensive aquaculture systems, leftover feed, animal waste, and dead algae can accumulate quickly.
If not properly managed, these organic materials decompose and produce toxic gases, reduce water quality, and directly affect aquatic animal health.
Using aquatic probiotics provides several important benefits:
1. Improving Pond Water Quality
One of the most important functions of probiotics is improving and maintaining water quality.
Beneficial microorganisms help break down:
- Excess feed.
- Shrimp and fish waste.
- Dead plankton.
- Organic matter accumulated in the water.
As a result, pond water becomes more stable, reducing problems such as cloudy water, unpleasant odors, and abnormal fluctuations in water color.
2. Controlling Toxic Gases NH3, NO2, and H2S
Toxic gases are among the main causes of slow growth, reduced feeding activity, and mass mortality in shrimp and fish.
These include:
- NH3 (ammonia): Damages gills and affects respiration.
- NO2 (nitrite): Reduces the ability of blood to transport oxygen.
- H2S (hydrogen sulfide): Produced during the decomposition of organic matter at the pond bottom.
Beneficial microorganisms in aquatic probiotics help accelerate the conversion of these toxic compounds into less harmful forms, creating a safer living environment for aquatic animals.
3. Stabilizing the Microbial Community in Ponds
A healthy aquaculture pond requires a balance between beneficial microorganisms and harmful bacteria.
When probiotics are regularly added, beneficial bacteria can grow strongly, competing with harmful microorganisms for nutrients and living space.
This helps:
- Limit the growth of disease-causing bacteria.
- Reduce the risk of disease outbreaks.
- Maintain a stable farming environment.
4. Improving Shrimp and Fish Health and Growth Rate
Clean and stable water conditions help aquatic animals reduce stress, improve feeding activity, and absorb nutrients more effectively.
In particular, some probiotic products for shrimp are added directly to feed to:
- Improve digestive function.
- Increase nutrient absorption.
- Enhance disease resistance.
- Promote uniform growth.
Common Types of Aquatic Probiotics Today
Depending on their purpose, aquatic probiotics are divided into several groups.
Water Treatment Probiotics
This is the most commonly used type of probiotic product, with functions including:
- Cleaning pond water.
- Decomposing organic matter.
- Stabilizing water color.
- Controlling excessive algae growth.
Bottom Sediment Treatment Probiotics
The pond bottom is where most waste accumulates during farming. These probiotic products usually contain microorganisms capable of breaking down organic sludge, reducing unpleasant odors, and limiting toxic gas formation.
Digestive Probiotics
These products are usually mixed with feed to support the digestive system of shrimp and fish.
Benefits include:
- Improving feed digestion.
- Helping aquatic animals absorb nutrients more effectively.
- Reducing intestinal problems.
How to Use Aquatic Probiotics Effectively
To maximize the effectiveness of aquatic probiotics, farmers should use them correctly.
1. Use the Correct Dosage
Each probiotic product has different microbial concentrations and usage instructions. Using too little may not provide the desired results, while excessive use can cause unnecessary waste.
Farmers should follow the dosage instructions provided on the product label.
2. Choose the Appropriate Application Time
The best times to apply probiotics are usually:
- In the morning when dissolved oxygen levels are higher.
- In the cool afternoon when temperatures decrease.
Avoid applying probiotics during extremely hot weather or when the pond contains high levels of disinfectants or chemical treatments.
3. Do Not Use Together with Disinfectants
Disinfectants, chlorine, and antibacterial chemicals may kill beneficial microorganisms.
Therefore, sufficient time should be allowed between chemical treatments and probiotic applications.
4. Maintain Regular Use
Aquatic probiotics are not an immediate solution for every problem. Regular supplementation helps maintain microbial balance and prevent potential issues in farming ponds.
Tips for Choosing High-Quality Aquatic Probiotics
Today, many different biological products are available on the market. To select a suitable product, farmers should consider:
Microbial Composition
Prioritize products containing beneficial and commonly used strains such as:
- Bacillus.
- Lactobacillus.
- Nitrosomonas.
- Nitrobacter.
High Microbial Density
Products with high concentrations of beneficial microorganisms generally provide better treatment efficiency, especially in intensive farming systems.
Clear Product Origin
Choose products with:
- Complete manufacturer information.
- Clear usage instructions.
- Quality certifications.
- Reliable expiration dates.
Suitability for Each Farming Model
Different aquatic species have different requirements. For example:
- Shrimp farming: Requires greater focus on controlling toxic gases and stabilizing pond bottoms.
- Fish farming: Requires stronger control of organic matter and overall water quality.
Therefore, probiotic products should be selected according to the specific farming model.
Common Mistakes When Using Aquatic Probiotics
Although aquatic probiotics provide many benefits, incorrect use can reduce their effectiveness.
Common mistakes include:
- Using probiotics without checking water quality.
- Applying probiotics together with disinfectants.
- Failing to maintain regular application.
- Storing products in high-temperature conditions.
- Choosing products with unclear origins.
To achieve the best results, farmers should combine probiotic use with proper feed management, environmental monitoring, and regular observation of aquatic animal health.
Aquatic probiotics are an important solution that helps farmers control water quality, reduce toxic gases, prevent disease outbreaks, and improve production efficiency.
With the current trend toward sustainable aquaculture development, the application of biological products is becoming increasingly necessary.
Choosing the right probiotic product, applying it correctly, and maintaining regular use will help create a stable farming environment, support healthy shrimp and fish growth, and bring higher economic returns to farmers.
