Effective Strategies for Controlling Ammonia in Vannamei Shrimp Ponds

Controlling ammonia in Vannamei shrimp ponds has become one of the essential tasks for every shrimp farmer. Excess ammonia levels above the normal threshold can have detrimental effects on the pond environment and shrimp health.

Fundamentally, ammonia in pond water cannot be completely eliminated as it plays a crucial role in the nitrification process. However, ammonia levels must always be carefully monitored to prevent them from exceeding the allowable threshold.

In this article, we will delve further into effective strategies for managing ammonia in shrimp ponds. Read on to discover this valuable information in its entirety!

Also Read: Toxic Substances in Shrimp Ponds: Hidden Threats to Shrimp Survival

Ammonia in Vannamei Shrimp Ponds

Ammonia is a chemical compound formed as a byproduct of shrimp metabolism and undigested feed. High concentrations of ammonia can disrupt shrimp’s health, poison them, and even lead to mortality. Therefore, controlling ammonia is key to achieving success in Vannamei shrimp aquaculture.

Ammonia is a chemical compound generated from shrimp metabolism, the accumulation of unconsumed feed, decomposition of dead organisms, and feces. In shrimp ponds, there are two types of ammonia: free ammonia (NH3) and ionised ammonium (NH4+), which are accumulated as Total Ammonia Nitrogen (TAN).

Essentially, ammonia is also required in the shrimp pond ecosystem for the nitrification process by plankton. However, ammonia levels in the pond should not exceed 0.1 ppm to ensure healthy shrimp growth.

Causes of High Ammonia Levels in Ponds

1. Shrimp Metabolism

The metabolism of Vannamei shrimp produces ammonia as a byproduct. The more shrimp cultivated in the pond, the more ammonia is produced through their metabolic processes.

2. Overfeeding

Overfeeding can result in an excess of leftover feed that rots and accumulates at the pond’s bottom, becoming a source of ammonia.

3. Suboptimal Water Temperature

Elevated water temperatures can increase shrimp metabolism, leading to higher ammonia production. Conversely, when the water temperature is too low, the growth of ammonia-reducing bacteria can be inhibited, impeding ammonia breakdown.

4. Poor Waste Management

Organic waste from Vannamei shrimp cultivation, such as unconsumed feed, feces, and deceased organisms, accumulates at the pond’s bottom. Inefficient waste management systems can lead to waste accumulation, which contributes to elevated ammonia levels.

Strategies for Controlling Ammonia

1. Efficient Waste Management System

In Vannamei shrimp ponds, an efficient waste management system is a crucial initial step. Ensure that leftover feed and shrimp waste do not accumulate at the pond bottom, which can lead to excess ammonia.

2. Proper Aeration

Using aerators or devices to improve water circulation and oxygen levels in the pond is essential. Sufficient oxygen helps reduce the production of harmful ammonia and creates a healthier environment for Vannamei shrimp.

3. Feed Management

Precisely control feed distribution. Provide shrimp with the right amount of feed to prevent feed excess that can become a source of ammonia. Use high-quality feed that is well-absorbed by the shrimp.

4. Beneficial Ammonia-Degrading Bacteria

Introducing beneficial ammonia-degrading bacteria, such as Nitrobacter, into the pond can help convert ammonia into less harmful compounds like nitrate. This reduces ammonia levels in the pond water.

5. Regular Monitoring

Perform routine water quality monitoring in the pond. Periodic water quality testing helps identify changes in ammonia levels and allows for prompt action when ammonia spikes occur.

6. Water Temperature Control

Maintaining an optimal water temperature is crucial. Vannamei shrimp are more susceptible to ammonia at high water temperatures. Ensure the water temperature falls within the appropriate range for shrimp growth.

How to Properly and Completely Distribute Vannamei Shrimp Fry!

The correct distribution of vannamei shrimp fry is a crucial first step in determining the success of aquaculture. Proper fry distribution techniques can increase the number of surviving fry, resulting in a high survival rate (SR).

Fry are usually distributed when they reach PL10 to PL15. Additionally, they often need to undergo various tests to ensure their quality. During the distribution process, fry cannot be immediately released into the pond. Instead, it’s necessary to adjust the temperature first to prevent stress, which can lead to mortality. Read on to learn more about the proper and correct method for distributing Vaname shrimp fry.

Also Read: 7 Characteristics of High-Quality Vannamei Shrimp Seed

Characteristics of Good Fry

As one of the keys to successful Vaname shrimp cultivation, you must ensure that the fry to be distributed are of ideal quality. Here are some characteristics to look for:

1. Uniform Fry Size

Fry with uniform size indicate high quality. Uniform size suggests that the fry have grown normally and received consistent nutrition. Additionally, uniform fry size can prevent cannibalism.

2. No Physical Deformities

Healthy fry should have complete and well-developed body parts, including straight tails, perfectly shaped eyes and eye stalks, and intact swimmerets.

3. Full Gut Content

Healthy fry should have a full gut as an indication of good feeding. Conversely, fry with empty guts may mean they are not eating or are experiencing stress.

4. Active Fry Movement

Another sign of quality fry is their active and agile movement, which is assessed through activity tests. This is because fry are sensitive to external stimuli.

5. Free from Various Diseases

Shrimp diseases can be transmitted from broodstock to fry. Therefore, shrimp farmers must ensure that the fry are free from various pathogens through PCR testing.

6. Passes Stress Tests

Minimizing stress on fry is a top priority during the hatchery process. Stressed fry have a lower chance of survival.

7. Sourced from a Trusted Hatchery

To obtain the highest-quality fry, you should get them from a trusted hatchery. This ensures that the breeding process has been closely monitored to maintain quality.

How to Distribute Vannamei Shrimp Fry

1. Choosing the Right Distribution Time

Before distributing vannamei shrimp fry, you must determine the appropriate time for their release. Typically, fry are distributed in the morning or evening when the air temperature is lower to minimize fry stress.

Also, ensure that the weather conditions are stable to prevent sudden changes in the pond water quality parameters.

2. Pond Preparation

Preparation of the aquaculture pond is a critical aspect of the vannamei shrimp fry distribution process. Ensure that the pond is free from various pests and pathogens that could harm the fry.

Additionally, check that the water parameters in the pond are within the optimal range, including pH, alkalinity, salinity, dissolved oxygen, and water temperature. If all these parameters are in the optimal range, you can start transferring the fry to the pond while keeping them in plastic bags to allow them to acclimate.

3. Fry Adaptation to Pond Water

After the pond is ready, you cannot simply release the fry directly. They need to go through an adaptation process to prevent sudden environmental changes that may stress the shrimp.

This adaptation is done by floating the bags containing the fry in the pond for 15-30 minutes. Then, open the bags, measure the salinity and temperature of the water inside the bags and in the pond. The temperature difference should not exceed 2 degrees Celsius, and the salinity difference should not be more than 5 ppt.

To expedite the adaptation, you can gradually add pond water to the bags until the temperature and salinity match.

4. Distributing Fry into the Pond

Once the fry have adequately adapted to the pond environment, you can release them into the pond. Adapted fry will exhibit active movement and swimming within the bags.

Fry can be released into the pond using two methods: the first involves slowly releasing them directly, and the second method involves adding Artemia (natural shrimp feed) first and then, after 30 minutes, releasing the shrimp through a tube using the force of gravity.

5. Initial Feeding (Blind Feeding)

After distributing the fry into the pond, provide appropriate initial feed to support their growth and survival. Blind feeding can be employed from day-old postlarvae (DOC 1) up to day-old postlarvae 30 (DOC 30).

Application of Proper Biosecurity for Shrimp Ponds

Biosecurity for shrimp ponds involves a series of measures to prevent the entry of diseases into the pond area. The scope of biosecurity typically includes both the cultivation ponds and the entire pond area.

As the saying goes, “prevention is better than cure,” biosecurity is one of the best ways to minimize the risk of losses due to diseases during shrimp cultivation. However, its implementation must adhere to the established standards.

Applying biosecurity in shrimp ponds is essential to reduce the risk of cultivation failure. This applies to all types of ponds, ranging from traditional to super-intensive scales.

So, how can we properly apply biosecurity and adhere to the standard guidelines? Let’s explore further in this article.

Also Read: 12 Equipments for Vannamei Shrimp Ponds that Must Be Prepared

Proper Application of Biosecurity

In the application of biosecurity for shrimp ponds, several aspects need to be considered, including juveniles (benur), shrimp feed, water, probiotics, and others.

1. Using High-Quality Shrimp Fry (Benur)

The first step in implementing biosecurity is to select high-quality and certified shrimp fry (benur). Ensure that the juveniles you choose are free from diseases to prevent infections and growth issues in the future.

2. Monitoring Water Quality in the Ponds

Water quality in the ponds is a critical aspect that must be monitored throughout the cultivation process. Regularly test water quality parameters to ensure that the pond water remains in optimal conditions. Additionally, you can add probiotics to improve water quality and enhance the shrimp’s immune system, protecting them from diseases.

3. Paying Attention to Accessibility

The accessibility of the pond, including the entry and exit of vehicles, people, and animals, can act as vectors that carry diseases into the pond. To prevent pathogens from entering the pond, you can implement the following activities:

Limiting the number of people entering the pond.
Restricting access to the cultivation area.
Establishing reporting and authorization procedures for pond entry (all visitors must report their presence).
To prevent wild animals from entering the pond, you can install deterrents such as bamboo fences, Crab Protecting Line (CPL), and Bird Scaring Line (BSL).

Another biosecurity measure is to use disinfectants at every pond entrance for people and vehicles entering the area. This helps prevent potential pathogens from being carried in by individuals or vehicles.

4. Following Biosecurity Protocols during Juvenile Stocking

During the juvenile stocking process, biosecurity protocols should be strictly followed and monitored, starting from the arrival of the juveniles to their release into the pond. The truck transporting the juveniles should pass through a wheel bath facility before entering the pond area. Additionally, the bags containing the juveniles should be disinfected (by dipping them in a disinfectant). Equally important is the requirement for all personnel involved in the stocking process to disinfect themselves before entering the cultivation pond, especially during manual stocking.

5. Pond Water Management

Implementing biosecurity in shrimp ponds also involves managing the water that flows in and out of the pond. This is typically achieved by providing storage tanks and treatment ponds to filter and disinfect the water before it enters the main pond.

In the storage tanks, physical treatments such as sediment settling, coarse particle filtration, and total organic matter reduction from the water source are conducted. The treatment ponds involve chemical processes aimed at killing pathogens before the water enters the cultivation pond, and one common method is disinfecting the water in the treatment pond. This reduces or eliminates the possibility of pathogens in the water entering the cultivation pond.

Likewise, the water leaving the pond must also be treated before being discharged into the environment to preserve the surrounding ecosystem. Directly discharging water without filtration could lead to environmental pollution and disease outbreaks due to pathogen contamination.

Cultivation Preparation Stage

1. Pond Preparation

In vannamei shrimp cultivation, the first thing you must do is the Preparation of the pond to form an ecosystem conducive to the maintenance of shrimp during one cultivation cycle.

During pond preparation, there are several things you must ensure:

The pond is clean, dry, and not leaking.
Adjustment of aeration and turbulence needs with production targets, configurations, energy availability, and cultivation systems.
Ensuring ponds are free from potential remnants of microorganisms that can harm aquaculture activities, such as bacteria, viruses, etc.

2. Preparation of Farm and Laboratory Equipment

Each pond must have its equipment and may be used differently from other ponds. Both tools in the field, such as siphon hoses, Secchi disks, scoops, wall mounts, buckets, and water samplers, and laboratory equipment, such as water quality checkers, pH meters, and DO meters.

Therefore, the farmers must properly prepare every tool needed. Ensure all the equipment is complete and ready to use before the cultivation cycle begins.

3. Preparation of Human Resources

Not only pond preparation and equipment, competent and adequate human resources must also be prepared for vannamei shrimp cultivation. This is so that the cultivation of vannamei shrimp can run effectively and efficiently.

Make sure the number of human resources, expertise, and division of tasks for each person is carried out clearly. Good human resource preparation will result in neat pond data recording and more successful vannamei cultivation.

4. Pond Sterilization

Pond sterilization is included in the water preparation stage, which forms the essential ecosystem where the shrimp will grow and develop. Farmers must ensure that the combination of autotrophic and heterotrophic bacteria in the pond is balanced through this stage.

In addition, make sure no pathogens and other pests remain in the pond. Usually, sterilization is carried out by adding chlorine according to the rules and dosages that apply.

5. Microorganism Spreading

The final Preparation before cultivating vannamei shrimp is the spreading of microorganisms. These microorganisms can later become natural food for shrimp. But not only that, but microorganisms can also help absorb ammonia, produce oxygen, stabilize water temperature, and fight harmful bacteria.

The selection of fry is the key to success in vannamei cultivation. The ideal fry should be disease-free and disease resistant. In addition, several other criteria must be met, including body length > 10 mm, size variation < 1, intense color pigment, and active swimming spread.

Before the fry is stocked, acclimatization must first be carried out to accelerate the adaptation of the fry from the bag water medium to the pond water ecosystem. This stage also avoids stress on the fry and reduces the mortality rate when stocking.

2. Feeding Management

Intensive vannamei shrimp cultivation cannot be done without artificial feed. Therefore, farmers must prepare good feed management to maximize the cultivation that is carried out.

Shrimp feed management is a step to maximize the benefits of feed to support successful cultivation. Feed management is one of the most critical factors, especially about the capital spent. The more effective and efficient a person manages vannamei shrimp feed, the more efficient the money spent will be.

3. Do Routine Sampling

Routine sampling aims to determine the condition and development of shrimp during cultivation. Sampling is an important activity to see the growth of laws needed for evaluation, one of which is feeding.

Usually, sampling is carried out within a certain period to determine average body weight (ABW), growth (ADG), population estimation, survival rate (SR), biomass, and to observe the quality of the shrimp.

4. Water Quality Management

As long as vannamei shrimp cultivation takes place, farmers must implement good water quality management and continue to observe it. This is so that if there is a change or fluctuation in water quality parameters during cultivation, it will be easier for farmers to find out.

The water used for vannamei cultivation is seawater with a salinity level above 15 ppt which must be replaced every 60 days. While the parameters used to measure water quality include pH, DO, temperature, brightness, total ammonia nitrogen, NH3, total vibrio count, alkalinity, salinity, and the type and amount of plankton.

5. Vannamei Shrimp Treatment

Farmers must ensure that the shrimp are healthy and receive optimal nutritional intake during cultivation. Therefore various treatments, such as giving probiotics and vitamins, are necessary.

In addition, ponds must also be disinfected according to standards to inhibit the growth of microorganisms that are bad for the sustainability of cultivation.

6. Harvest

The last is the harvest stage, the process of picking the results from your vannamei cultivation. The harvest stage is divided into four: the overall harvest (total harvest), partial harvest (partial harvest), abnormal harvest, and emergency harvest.

A typical harvest occurs if the vannamei shrimp AW reaches more than 14 grams. Partial harvest is usually done when the pond capacity has reached the maximum limit. At the same time, abnormal and emergency harvests are carried out when certain things occur during cultivation, such as a high mortality rate.

5 Tips to Achieve Profitable Biofloc Vannamei Shrimp Farming

Biofloc technology in vannamei shrimp farming is an innovative approach that has gained popularity recently. This technology involves using microorganisms in the cultivation system, which can help maintain water quality and enhance shrimp health.

In vannamei shrimp farming, biofloc technology has proven effective in reducing feed costs, increasing shrimp’s growth rate and survival, improving the immune system, and minimizing the risk of diseases.

However, before implementing bio floc vannamei shrimp farming, it is essential to understand how this innovative technology works. Read on to learn more in the following article.

How to Use Biofloc in Vannamei Shrimp Farming?

The initial step in implementing bio floc technology for vannamei shrimp is creating a system. This system involves creating a cultivation environment that promotes the growth of beneficial microorganisms such as bacteria and algae.

Creating a biofloc cultivation environment can be done by maintaining a high content of organic matter in the water, which serves as a food source for microorganisms.

To manage the biofloc system, there are several factors to consider, including pond size, the stocking density of vannamei shrimp, and the type of shrimp feed used.

The ideal pond size for implementing biofloc technology is between 500 and 1000 square meters. The stocking density should be manageable, as it can lead to the accumulation of organic matter that reduces oxygen levels in the water. Additionally, the feed should have a high protein content and be easily digestible by shrimp.

Water is the main component in aquaculture, so every aquaculture activity must have good water quality management as well. Then, how to have it? Well, the first thing that we have to do is monitor water quality. This could inform you if there is a change in water quality parameters during cultivation.

Water quality measurements are carried out physically, chemically, and biologically. Physical measurements can be carried out directly in each shrimp pond with parameters pH, temperature, DO, and water salinity.

Meanwhile, chemical and biological parameters can be carried out in the laboratory with parameters such as alkalinity, an abundance of plankton species, total bacteria, total vibrio, nitrite, nitrate, ammonia, phosphate, TOM, and total suspended solids.

In addition, the basic management of shrimp ponds must also be considered for the sustainability of aquaculture. The basic management of this pond includes the layout of the waterwheel, the activity of removing sludge, and the treatment of decomposing bacteria.

2. Vannamei Shrimp Feed Management

Vannamei shrimp feed management is another element that must be considered in shrimp farm management. The goal is to maximize feed use to support success and efficiency in shrimp cultivation.

Feed management is important in terms of the efficiency of capital spending during cultivation. This is because almost 60% of the capital is spent on feeding vannamei shrimp.

Several steps in feed management can be done through blind feeding, feeding after the first month, and using anco control.

Vannamei shrimp health management is carried out to observe any changes in the shrimp. These changes are usually signs of health problems and certain diseases that attack the shrimp.

Observations can be made first by looking at the characteristics of healthy shrimp, such as having active movements, complete and intact limbs, red and bright gills, full and unbroken gut contents, proportional body shape, bright skin color and clean, tail intact, and normal length growth.

If some anomalies or discrepancies appear during a health observation, be sure to immediately investigate and mitigate the disease.

4. Aquaculture Waste Management
