Septic-tank microbes in shrimp farming and 4 things you need to know

1. What are septic-tank microbes in shrimp farming?

• Aerobic bacteria: These bacteria need oxygen to grow and develop. They can decompose organic waste such as feces, toilet paper, food scraps, etc. into water and CO2 gas.
• Anaerobic bacteria: These bacteria don’t need oxygen to grow and develop. They can decompose hard-to-break-down organic waste such as fats and oils into simpler substances.
• Facultative bacteria and yeast: This group of microorganisms can work in both oxygen-present and oxygen-free environments, flexibly decomposing organic matter. Yeast can decompose organic waste such as toilet paper and food scraps into water and CO2 gas.

Septic-tank microbes used in shrimp farming are simply a type of biological product. This biological product includes many types of probiotic enzymes that decompose waste and keep the pond environment clean. At the same time, it reduces the risk of disease in shrimp, creating an environment for shrimp to grow healthier.

Septic-tank microbes in shrimp farming help increase productivity and reduce disease

Thanks to applying septic-tank microbes, the shrimp farming environment will be treated more effectively, limiting disease outbreaks that affect productivity. However, to maximize the effectiveness of this biological product, farmers need to use it correctly.

2. Main effects of septic-tank microbes in shrimp farming

Today, septic-tank microbes in shrimp farming are becoming increasingly popular. Thanks to this type of microbe capable of decomposing organic matter, the organic decomposition process has been significantly shortened, and the amount of toxic gas in shrimp ponds has also decreased significantly.

2.1 Supports the decomposition of organic matter

Organic matter present in the shrimp farming environment mainly consists of leftover feed, shrimp waste, and incompletely decomposed algae remains… Their accumulation is sometimes the cause of increased pathogen growth and large consumption of dissolved oxygen. To limit disease outbreaks, farmers should find ways to speed up the decomposition of organic matter.

Septic-tank microbes speed up the decomposition of organic matter in ponds

Septic-tank microbes can secrete enzymes that help break down complex organic substances such as protein (protein), fat (lipid), or carbohydrates. At the same time, they convert these into smaller units, speeding up decomposition and helping purify the water source.

Many types of septic-tank microbes also help remove stubborn organic matter that accumulates on the pond bottom or clings to the surface of certain plants. This effectively cleans the shrimp farming environment, reducing dangerous pathogens.

2.2 Reduces NH3, NO2, and H2S levels

Besides harmful organic matter, the shrimp pond environment also contains many types of toxic gas. Specifically, anaerobic conditions at the bottom are considered the cause of H2S gas production.

In addition, the decomposition of organic matter also creates conditions for the production of NH3 (ammonia) and NO2 gas (nitrite). All three of these gases are very toxic, negatively affecting shrimp in the pond, causing stress and reducing respiratory capacity.

To eliminate these toxic gases, farmers should use highly active microbes. This biological product can shorten the organic decomposition process, stimulating the complete conversion of these toxic substances into less toxic compounds (such as nitrate) without producing toxic gas.

2.3 Prevents pathogenic microorganisms

Disease is one of the causes of declining shrimp productivity. In fact, in some farming cycles, farmers lose everything due to disease outbreaks.

Septic-tank microbes in shrimp farming help limit disease in pond-raised shrimp

Using highly active septic-tank microbes is considered an effective method for controlling disease through a biological competition mechanism. The beneficial microorganisms in the product occupy space and food sources, thereby inhibiting the growth of harmful microorganisms (such as Vibrio), creating a favorable environment for shrimp to grow healthily.

2.4 Helps stabilize shrimp gut health

According to several recent studies, scientists have shown that certain microbial strains (such as Bacillus subtilis and Lactobacillus) can help stabilize shrimp gut health. As a result, shrimp in the pond environment will absorb nutrients well and grow quickly and healthily.

When using septic-tank microbes supplemented with gut-friendly bacteria, farmers can more easily and proactively prevent common gut diseases in shrimp, such as white feces, loose stool, and bent gut.

2.5 Stimulates the growth of beneficial algae

Not only do they support disease prevention, but many types of water treatment microbes also help beneficial algae types reproduce and grow faster, such as green algae and diatoms.

On the other hand, septic-tank microbes also help limit the growth of many types of harmful algae, such as euglena and blue-green algae. This helps maintain a suitable aquatic environment for shrimp growth.

3. Instructions for using septic-tank microbes in shrimp farming

To maximize the effect of preventing disease and maintaining a clean pond environment for shrimp to grow quickly, farmers should use septic-tank microbes or a product with similar functions. The best septic-tank microbial product for shrimp ponds today is Emzeo Septic Tank & Cesspit Treatment 200g (or equivalent specialized products). Here are the detailed usage instructions:

• Step 1: Activate the product: Mix the septic-tank microbial product with clean water, at a ratio of 1 pack of 200g mixed with 20 liters of water. You should add molasses (1–3 liters) or rice bran as a food source to activate the microbes. While mixing, stir thoroughly so the product dissolves quickly in the water.
• Step 2: Ferment the biomass: After mixing, leave the solution mixture as is for about 30 minutes to several hours (depending on the strain). This allows the beneficial microorganisms to multiply to their maximum.
• Step 3: Spread into the pond: After 30 minutes, spread the freshly mixed solution into the shrimp pond area. 1 pack of 200g septic treatment yeast treats 100 to 200 m3 of pond water. During application, pour from one corner so the microorganisms gradually spread throughout the pond, helping to quickly decompose organic matter.

Farmers should pour septic-tank microbes into the pond while it’s still sunny

So, with just 3 simple steps, you have treated your shrimp pond water with septic-tank microbial biological product. In practice, septic-tank microbes have almost no negative impact on the health of the person applying them and are very environmentally friendly. If used correctly, shrimp productivity and quality will increase significantly.

4. Notes to know about septic-tank microbes in shrimp farming

Here are a few notes when using microbial products in shrimp farming:

• Use at the appropriate time: The suitable time to pour the mixed septic-tank microbes down into the shrimp pond slope is from 2 to 3 PM, while the sun is still mild. If it’s raining heavily or too overcast, farmers should not sprinkle this biological product into the shrimp pond. This is because rainwater will affect the effectiveness of septic-tank microbes by lowering the temperature and diluting the environment.
• Do not use septic-tank microbes together with disinfectants: Because strong disinfecting chemicals such as chlorine or antibiotics can easily reduce the effectiveness of septic-tank microbial products. If strong cleaning chemicals have been used, wait at least 3 days before using septic-tank microbes in the shrimp pond.
• Provide adequate oxygen for the shrimp pond: This is a basic condition for the microorganisms in septic-tank microbial products to work well, especially the aerobic bacteria group.

• Check the pond regularly: When using septic-tank microbes or any other product, farmers must pay attention to checking the shrimp pond every day. If any abnormality is detected, farmers need to find a solution immediately.
• Always wear protective gear when handling septic-tank microbes: Although it doesn’t seriously affect the user’s health, septic-tank microbial products still have an odor. So to limit odor as well as the freshly mixed solution getting on your body, wear full protective gear.

5. Should you use septic-tank microbes in shrimp farming?

Although septic-tank microbes are also a type of biological product with a very good ability to decompose waste and bottom sludge, note that septic-tank microbes and shrimp-farming microbes are two different products in terms of strain type and purpose of use.

Septic-tank microbes are manufactured to decompose organic waste in septic tanks and cesspits – an environment that is usually anaerobic, stable in temperature and pH. Meanwhile, shrimp-farming microbes are used to decompose organic waste in shrimp ponds – an aerobic environment (with water aerators), fluctuating in temperature, pH, and salt concentration.

Using non-specialized septic-tank microbes in shrimp farming can cause the following issues:

• Low effectiveness: The microbial strains in septic-tank microbes may not withstand the high salinity, fluctuating pH, or strongly aerobic environment of shrimp ponds, leading to low survival rates and unsatisfactory treatment results.
• Harmful to shrimp: Some types of septic-tank microbes (such as sulfate-reducing bacteria) can produce substances harmful to shrimp if not tightly controlled in the pond environment.
• Harmful to the environment: Organic waste in shrimp ponds decomposed by microorganisms will create nutrients, which can cause the growth of algae and pathogens harmful to shrimp and the environment.
• Ecological imbalance: Septic-tank microbes can promote the excessive growth of certain undesirable bacteria, causing biological imbalance in the pond.

Therefore, shrimp farmers should limit the use of septic-tank microbes in shrimp farming, and instead use specialized biological products for shrimp ponds. These microbial products are researched and manufactured to effectively decompose organic waste in shrimp ponds, while being safe for shrimp and the environment.

EmzeoTS biological product – specialized probiotic for shrimp ponds

6. Some notes when using septic-tank microbes in shrimp farming

Although specialized microbes should be prioritized, in some special cases septic-tank microbes can still be used in shrimp ponds, such as: when the pond has too much bottom sludge, excessive leftover feed, excessive waste, feces, or shrimp shell remains accumulating more than usual.

• Use septic-tank microbes with a clear origin, manufactured by reputable units with quality certification.
• Mix septic-tank microbes with clean water according to the instructed ratio and activate (ferment) them according to the recommended process to increase bacterial density and survival rate.
• Spread the mixed microbial solution evenly across the pond surface, focusing especially on the pond bottom and near the water aerators, to ensure the microorganisms are evenly distributed and receive enough oxygen for decomposition activity.
• Use septic-tank microbes periodically (usually every 7–10 days, depending on the pond’s biological load) to maintain a stable density of beneficial microbes, thereby achieving the highest treatment effectiveness. Absolutely avoid using them at the same time as strong disinfecting chemicals such as chlorine, BKC, or formalin.
• Monitor environmental indicators (pH, dissolved oxygen) after application to ensure the microorganisms work effectively; if needed, increase aeration.
