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!

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.

Types of Vannamei Shrimp Feeds to Make Your Shrimp Grow Faster

Vannamei shrimp feed is one of the important things that must be considered in shrimp farming. The reason is, each farmer has to spend a lot of money on this feed compared to other pond needs.

In addition, shrimp feed also plays an important role in the growth of vannamei shrimp. If you provide feed with the right dose and nutrition, vannamei shrimp will grow faster, and your cultivation can provide optimal results.

So, what are the types of vannamei shrimp and what are the criterias for a good shrimp feed? Check this article out to get to know about it!

Vannamei shrimp natural feed is a type of feed that comes from nature without being processed first. This natural food can be phytoplankton and zooplankton which were previously prepared during farm preparation, as well as other animals and plants.

Traditional types of shrimp farms usually rely on this type of natural feed. Meanwhile, in semi-intensive, intensive, and super-intensive farms, natural feed is usually used as a companion to the artificial feed that has been given.

2. Artificial Feed

In contrast to natural feed, artificial feed is a type of feed that undergoes a processing process first to form pellets, crumble, or powder. Usually, a good artificial vannamei shrimp feed has additional nutrients to accelerate the growth of shrimp during cultivation.

Based on the shape, artificial feed is divided into three types, namely pellets, granules (crumbles), and powders.

– Pellet

Pellets are artificial feed for vaname shrimp in the form of tubes with different levels of hardness. In the pellets, there are usually special nutrients to accelerate the growth of shrimp. Starting from protein, carbohydrates, fat, fiber, and other important nutrients.

Vannamei shrimp feed in the form of pellets is generally used to feed shrimp that have entered the juvenile stage (juvenile) until ready to harvest.

– Granules (Crumble)

Granules or crumble are vannamei shrimp feed in the form of coarse granules. Usually, this type of shrimp feed is given to shrimp aged 16-45 days.

Granules can be made from crushed pellets or agglomerated powder feed types. Meanwhile, in terms of nutritional content, the type of vaname granule shrimp feed has nutrients that have been adjusted to the age of the shrimp.

– Powder

Good Vaname Shrimp Feed Criteria

Before feeding vaname shrimp, you must first make sure that the feed you are going to give is still feasible. This is because spoiled and improper feed can have a negative impact on the quality of shrimp development.

There are several criteria for good feed that need to be considered before you spread it, including the following.

Characteristics of Good Vannamei Shrimp Feed

Looks good without mold
Dry
No clumping
Undamaged
Has a distinctive smell
Whole packaging
The shape is uniform
Water stability 2-3 hours

This is the Process of Molting in Shrimp and How to Handle It

Molting in shrimp is replacing the old shell with a new one which always occurs in every shrimp life cycle. This is because shrimp are crustaceans whose body surface is covered by an exoskeleton called a cuticle.

The molting process is often the thing that most farmers worry about. Because shrimp will be more susceptible to disease in this phase, however, the molting process will always occur as the life of the shrimp develops.

Let’s get to know in more detail what molting is and how it’s done in this article!

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

What Is Molting in Shrimp?

In simple terms, molting can be referred to as replacing the outer shell layer in shrimp. During the molting process, after the outer shell layer of the shrimp is shed, the same layer of skin will grow to replace it.

Molting Process in Shrimp

The molting process in vannamei shrimp is divided into four stages: post-molt, molting, inter-molt, and pre-molt.

1. Post Molt

Post-molt is the phase where the shrimp has just experienced the release of the exoskeleton from the previous molt process. Usually, in this phase, the shrimp will absorb a lot of water to strengthen their new cuticles.

2. Molting

Molting is the phase when the shrimp begins to shed its outer shell. For the shrimp’s exoskeleton to fall off entirely, the shrimp will relax its muscles and slowly start to come out of its old body.

3. Inter-Molt

The shrimp exoskeleton will harden during the inter-molt phase because the shrimp absorbs more protein and minerals during this phase. Meanwhile, shrimp appetite is not disturbed and even tends to increase.

4. Pre-Molt

Pre-Molt is when the shrimp prepares for the following molting process. The cuticle layer will slowly grow and be visible to the naked eye. Usually, in this phase, the shrimp appetite will decrease than usual.

Also Read: 5 Types of Shrimp Pond Aerators and Their Function

How Often Does Molting Occur?

Under healthy conditions, adult shrimp molt or change their skin every 3 to 4 weeks. However, younger shrimp will change their skin more frequently, every 1 to 2 weeks, to be precise. This is because young shrimp experience a faster growth process.

Meanwhile, replacing old shells with new shells in shrimp only takes a few hours.

How to Handle Shrimp When Molting

In a way, molting is a reasonably crucial phase in shrimp farming. The reason is shrimp that fail in the molting phase will die. Therefore farmers need to ensure the molting process runs smoothly.

In this case, several technical conditions must be considered for the smooth running of the molting process, starting from the quality of pond water maintained, the level of calcium and other minerals in the water remaining stable, and so on.

In addition, remember to adjust the shrimp feed given. Remember, during the inter-molt phase, the shrimp’s appetite will increase. Meanwhile, during the pre-molt phase, shrimp appetite tends to decrease.

These are 7 Tips for Successful and Profitable Vannamei Shrimp Harvest

A successful vannamei shrimp harvest is what all farmers dream of. Because, with a successful harvest, the farmers can get enormous profits. However, a good and proper cultivation process is needed to get to that point.

As the final stage in cultivation, harvest is the most awaited stage for the farmers. The harvesting process must be done promptly. There are particular techniques to avoid killing or damaging the shrimp.

So, for this reason, in this article, we will share tips on how to harvest vannamei shrimp correctly and the steps that must be followed to produce a profitable harvest.

Also Read: How to Cultivate Vannamei Shrimp from Preparation to Harvest

Tips for Vannamei Shrimp Harvest

1. Monitor Shrimp Conditions

Vannamei shrimp is a species whose growth period is faster than other shrimp. Therefore, ensure your shrimp have reached their ideal size to get the best yields.

2. Before Shrimp Harvest Time, Make Sure the Shrimp are not Infected with Diseases

Before harvesting vannamei shrimp, farmers need to ascertain whether the shrimp have signs of disease or not. Observations can be made by looking at the shrimp’s physical condition and behaviour.

If shrimp are found to be infected with certain diseases, harvesting activities can be adjusted to mitigate the disease that attacks the pond.

3. Ensure the Pond Water Level is Right

After deciding to harvest shrimp, the pond water level before it begins is the first thing to pay attention to. It would be best if you first lowered the water level by considering several parameters, such as the shrimp biomass in the pond, the area of the pond, the speed of water drainage, the slope of the pond bottom, and so on.

Pond personnel responsible for harvesting must know each pond well to determine the optimal water level before harvesting the shrimp.

When lowering the water level, be sure to do it carefully so that the shrimp are not stressed, which can generally trigger massive moulting.

4. Use Proper Harvesting Techniques for Shrimp Harvest

When harvesting vannamei, it is essential to use proper techniques to minimize stress on the shrimp, for example, by using a net to carefully remove the shrimp from the pond or using a vacuum system to suck the shrimp out of the pond.

Using nets or nets is a manual harvesting technique practised for many years. Meanwhile, many ponds have recently switched to mechanical harvesting using various equipment, such as impeller pumps.

Harvesting mechanically allows farmers to harvest their shrimp more quickly and does not require a lot of technicians to do it. However, farmers must also ensure the post-harvest stage to avoid delays and backlogs that affect shrimp quality.

5. Complete the Shrimp Harvest in the Optimal Time

Ideally, harvesting process should be completed within a few hours, depending on the area of the pond and the amount of biomass. The goal is for the shrimp in the pond to remain in good condition and not stressed.

Harvest time is also determined by the speed at which the water level drops. In addition, starting harvesting with a water level that is too high can also have unwanted consequences. For example, harvesting time is too long and can cause stress and massive molting.

6. Store Shrimp the Right Way

After harvesting the vannamei shrimp, the next step is storing the shrimp, which must also be done correctly. The goal is to keep the shrimp fresh and maintain their quality.

The usual method is to store the prawns in the fridge and cool them to the right temperature. In addition, make sure the shrimp are not exposed to air with too high humidity.

7. Pack Shrimp Properly

The last tip for harvesting shrimp is packing shrimp in the right way. This is to ensure that the shrimp remains fresh during the distribution process. Packaging can be done by vacuum sealing, refrigerating containers, or packing the shrimp using insulating materials.

How to Maintain the Water Quality for Vannamei Shrimp Ponds to Stay Optimal

Ponds are artificial ecosystems where vannamei shrimp grow until they are ready to be harvested. One of the efforts to protect the pond ecosystem is maintaining water quality. Therefore, farmers must know how to maintain pond water quality.

Maintaining optimal pond water quality will directly impact shrimp health by preventing unwanted disease and pathogen infections. Come on, see how to maintain pond water quality so that it remains optimal in this article!

Also Read: The Importance of Wastewater Treatment Plant (WWTP) for Shrimp Ponds

How to Maintain Pond Water Quality Remains Optimal

1. Perform Routine Monitoring of Water Quality

Monitoring water quality is the first way farmers must maintain optimal water quality. Monitoring through routine testing of water quality parameters can more quickly identify fluctuations or imbalances of each parameter.

Thus, the farmers can immediately take appropriate action to maintain optimal water quality.

2. Make sure the Aeration System is Working Optimal

Aeration is generally used to maintain the availability of dissolved oxygen levels in pond water so that it is sufficient for the needs of vannamei shrimp.

In addition, aeration is also beneficial for the water circulation system and reduces the accumulation of organic matter in ponds. Usually, the number and type of aerators and waterwheels needed depend on each pond’s stocking density and area.

3. Maintain the Presence of Beneficial Bacteria

In the vannamei shrimp pond ecosystem, beneficial bacteria play an important role in maintaining pond water quality. These bacteria can break down organic matter, reduce ammonia and nitrate levels, and control algae growth.

4. Do Algae Control

Algae growth is one of the common problems that can cause an imbalance in water quality in pond ponds. Regular algae control can help maintain optimal water quality.

Ways that can be done to deal with excessive algae in shrimp ponds include reducing nutrients, ensuring continuous aeration, and increasing water salinity.

5. Ensure Water Circulation Goes Well

Maintaining circulation is very important to ensure optimal water quality in pond ponds. Oxygen levels, nutrients, and beneficial bacteria can be distributed homogeneously throughout the pond if the water circulation runs optimally.

In addition, with good water circulation, pond ponds can also avoid the accumulation of organic matter (TOM) and unwanted algae growth.

6. Implement Proper Waste Management

One of the main causes of poor water quality in vannamei shrimp ponds is the accumulation of organic waste. Proper waste management through the use of filtration systems and regular water replacement will help maintain good water quality.

7. Good Feed Management

Implementing good and measured feed management plays a crucial role in maintaining water quality. Overfeeding can increase organic waste in the pond water, affecting its quality and making it worse.

Economic Strategies in Shrimp Farming During Price Downturns

economic strategy of shrimp farming — Source: DELOS Documentation

A declining shrimp price presents a major challenge for farmers to achieve high profitability. Therefore, an economic strategy in shrimp farming is necessary to address this issue.

Managing operational costs (BOP) becomes the primary key to optimizing profitability when shrimp prices are declining. In this situation, carefully considering operational costs concerning shrimp prices per size becomes crucial.

Furthermore, several other strategies can be applied by farmers. Find out more about them in this article.

Also Read: Vannamei Shrimp Feed Management Tips for Your Anti-Loss Cultivation!

Strategies to Face Declining Shrimp Prices

1. Calculation of Operational Costs (BOP) and Shrimp Prices per Size

As the vannamei shrimp harvesting approaches, farmers need to consider various factors, such as operational costs and shrimp prices per size. For instance, when harvesting at the early DOC stage with sizes ranging from 100-90, considerations of a still-high survival rate (SR) and a low feed conversion ratio (FCR) of around 1.0 are crucial.

With shrimp prices around 43-45 thousand, the estimated production cost is approximately 30-35 thousand, resulting in a margin of about 10-15 thousand per kg of shrimp. However, waiting for shrimp to reach larger sizes could pose significant risks, especially when the increase in price per size doesn’t hold much economic significance.

2. Determining the Cost Price (HPP) at Specific Sizes

Farmers need to calculate the Cost Price (HPP) at specific sizes or DOC stages that yield the best margins. The decision to harvest shrimp should be based on a well-calculated economic assessment. Currently, both small and large-sized shrimp may not necessarily yield optimal profits. Hence, meticulous calculation becomes paramount.

Also Read: Addressing Harmful Algal Blooms in Shrimp Ponds

3. Adjustment to Low Prices

During periods of declining shrimp prices, farmers typically gather information about local and factory prices to compare. They also consider production costs and differences in prices across sizes to achieve the most profitable size. In such situations, recalculating the HPP of shrimp becomes essential to minimize production costs and adapt to lower shrimp prices.

4. Cultivating with Efficiency and Precise Calculation

Financially sound farmers persist in production to avoid being burdened by fixed costs. When facing a scenario of declining shrimp prices, recalculating production costs against shrimp prices becomes crucial. Cultivating with care and meticulous calculations helps minimize losses.

In the face of a trend of declining shrimp prices, farmers must re-evaluate economically. Comparing production costs against shrimp prices is a critical step in maintaining profitability.

5 Stages of Vannamei Shrimp Pond Preparation Before Doing Cultivation

Cultivating vannamei shrimp pond is a very profitable business. What’s more, vannamei shrimp is a type of shrimp that grows quickly from fry to harvest. That is, one cycle only takes three months.

Vannamei shrimp pond plays a crucial role in aquaculture. Because, in this pond, the shrimp will be raised until they are ready for harvest later. Therefore, you need to prepare the pond well.

This pond preparation aims to support the formation of an ecosystem conducive to maintaining shrimp during one cultivation cycle. What preparations need to be made, and what are the steps? Read more in this article!

Also Read: 4 Types of Vannamei Shrimp Farms You Have to Know

Vannamei Shrimp Pond Preparation Stages

1. Pond Cleaning

The earliest preparation for vannamei shrimp pond is the cleaning stage. In this stage, waste disposal is usually carried out, especially organic and phosphate waste accumulated at the bottom of the pond.

While the cleaning method can be done in two ways, namely the dry method and the wet method.

a.) Dry Method

Cleaning vannamei shrimp pond using the dry method uses sunlight to dry them. The trick is to drain and let the shrimp pond be in the sun for 10-30 days.

Furthermore, the waste at the bottom of the pond begins to be cleaned and disposed of in a predetermined place. However, this dry method cannot be applied to all parts of the pond, so it must be cleaned using a wet method.

b.) Wet Method

In areas where vannamei shrimp pond cannot be completely drained, they will usually be cleaned using a wet method. This method is carried out by spraying high-pressure air to remove waste from the previous cultivation cycle.

The wet method has an advantage in terms of time compared to the dry method because it only requires a short time, making it more effective and efficient.

2. Liming

After the vannamei shrimp pond are cleaned, the pond must be filled with water and left overnight before rinsing to remove residual waste and increase the pH. This process must be continuously repeated until the pH of the water is above 7.

When the pH of the water reaches 7, liming can be done. The type of lime used in this process is usually CaCO3 or dolomite lime [CaMg(CO3)2] for pond water with a pH close to neutral. Meanwhile, for water pH below 5, hydrated lime [Ca(OH)2] is used.

In addition, you also have to calculate the amount of lime used carefully. This is to avoid the air pH being too high, which can increase ammonia toxicity and result in death in shrimp.

During the process, lime must be spread over the entire pond bottom and up to the top of the barrier. Most of the lime should also be applied over the feeding area and any parts of the pond that remain wet.

3. Extermination Predators

The next stage of preparation for vannamei shrimp pond is eliminating predators to prevent them from entering the pond area. The way to do this is to filter the water that will be used to fill the pond with a filter with a fine mesh.

These predators or intruders include fish, crustaceans, and other invertebrates that can eat shrimp food or even carry parasites and diseases.

In addition, during the first month of vannamei shrimp cultivation, water should only be added to the pond if the water quality is poor and causes the shrimp not to develop properly. This avoids the entry of competitors or predators for the shrimp.

4. Fertilization

The next step in preparing for the vannamei shrimp pond is fertilization. Shrimp pond must be given fertilizer to stimulate plankton growth to prepare ecosystems and natural food for vannamei shrimp.

Fertilizers must be dissolved before spreading over the pond water surface to avoid fertilizer deposition on the pond’s bottom. This is because the fertilizer settles at the bottom will fertilize the soil and accelerate algae growth.

After fertilization, the plankton will develop in a few days and the water will change color to slightly green.

5. Aeration

The final preparation stage for vannamei shrimp pond is preparing the needs for pond aeration and turbulence. This stage must be carried out based on consideration of production targets, configuration, energy availability, and cultivation systems.

Preparation of aeration aims to ensure the supply of dissolved oxygen, avoid dead currents, direct sediment, and prevent stratification of temperature and salinity in pond water.

The type of aerator used depends on the pond’s area and the water’s depth. For example, a pond with an area of 0.5-1 ha requires four aerators installed in the corners to encourage maximum water flow.

The aerator must be turned on 24 hours before the fry is stocked, so there is enough time to create currents and clean the vannamei shrimp feeding area.

Tips

How to Speed Up the Molting Period in Vannamei Shrimp

As a type of crustacean, vannamei shrimp must experience a period of molting or the release of their outer skeleton. Molting can occur several times throughout the shrimp’s life and growth. So, how do you speed up the molting period for vannamei shrimp?

Molting in vannamei shrimp is a hormonal phenomenon that occurs as it grows. The molting process occurs because the shrimp experience an increase in body volume, while the exoskeleton cannot increase in size due to its rigid nature.

The process of molting in shrimp can fail, which can cause death in shrimp. This is what makes the farmers must know how to improve the quality of the pond environment to expedite and accelerate the molting period in shrimp.

Also Read: This is the Process of Molting in Shrimp and How to Handle It

Molting Stages in Vannamei Shrimp

1. Pre-molt

Shrimp usually pass the first molting phase by preparing its body to release the carapace or outer shell of the shrimp. Usually, the shrimp’s appetite will decrease, and the cuticle layer will begin to grow.

2. Inter-molt

The intermolt phase is the stationary phase where the shrimp cuticle begins to harden. Shrimp mass growth also runs continuously, and their feeding activity is stable or reaches a maximum level.

3. Post-molt

In this phase, the shrimp recover from their previous molt. To strengthen the cuticles and adapt them to their new size, vannamei shrimp will absorb a large volume of water with a high mineral content. The new carapace will harden in a few hours.

Molting significantly disrupts the shrimp’s body as it needs time to recover after the molting phase. The cuticle is not yet fully functional, so the shrimp must mobilize its body reserves to harden the weak cuticle.

Shrimp, including the White Spot Syndrome Virus (WSS), are susceptible to diseases in this phase. This makes the farmers must always be aware of the various possibilities that will be faced during the shrimp molting phase.

How to Speed Up Shrimp Molting

Although molting is a natural process in the shrimp body, many possibilities can occur during this phase. If the molting process fails, the worst impact that can happen is the death of the shrimp. In addition, other effects can be shrinking the shrimp’s body and slowing its growth.

Basically, the molting process in shrimp cannot be accelerated, considering that this process occurs naturally and is hormonal. However, farmers can expedite the molting process in the following ways.

1. Ensure Shrimp Are Not Stressed

The first way to speed up molting is to keep the shrimp from getting stressed. If the shrimp experience stress, their growth will be hampered, and the disease risk will increase.

Several factors that can cause stress to shrimp include extreme and too fast changes in water quality parameters and poor feed quality.

For the molting process of the shrimp to run smoothly, the farmers must always check the water quality parameters regularly, ensure that they are always in optimal condition, and ensure the feed given to the shrimp is of high quality and has sufficient nutrition.

2. Check Shrimp Conditions Routinely

To ensure that the molting of the shrimp runs smoothly, use pond sampling techniques and carry out periodic inspections to monitor the progress of the molting process.

Check whether the shrimp shell or carapace has begun to harden or has been released. By checking the condition of the shrimp regularly, farmers can evaluate whether the molting is running smoothly and whether the growth of the shrimp is normal or not.

3. Adjust the Amount of Feed with the Molting Stage

By conducting sampling for routine inspection, farmers can find the stages of shrimp molting so that the amount of feed given can be adjusted according to the stages.

For example, in the pre-molt stage, shrimp tend to eat less. Meanwhile, at the inter-molt stage, shrimp feeding activity peaks, meaning farmers must provide a more significant portion of feed than usual.

Adjusting the amount of feed at the vannamei shrimp molting stage can help keep the shrimp healthy and grow more optimally.

4. Provide Additional Nutrition for Shrimp

Providing additional nutrition for molting shrimp, such as calcium and phosphorus, has a good effect on shrimp for the growth of new shells. This extra nutrition can be in the form of feed nutrition or directly into pond water.

In addition, providing additional essential minerals, protein, and other nutrients to shrimp feed and pond water can also help expedite the shrimp molting process.

This Is the Best Water Color for Vannamei Shrimp Pond

Pond water is an indicator that must always be considered when cultivating. The best color for vannamei shrimp pond is brownish green and dark green. This colors can describe the living conditions of the shrimp in it. However, this color only becomes a benchmark and farmer needs to check it with other indicators regularly.

Each pond can have a different color of the water. This color can indicate the types of organisms that are in it. Through the visible colors of pond water, farmers can identify anomalies and predict if problems arise.

What color of water is the best for vannamei shrimp pond? Let’s learn about it through this article!

The Meaning of Pond Water Colors

The color of pond water is not always bright blue like seawater. Many color variants indicate certain conditions in ponds. Here are the meanings of pond watercolors that you need to know.

1. Greenish Yellow

The color of pond water greenish yellow is indicating that the amount of phytoplankton in the pond is still unstable, so TSP or urea is needed. Farmers must carry out routine checks to observe changes when applying this fertilizer. If it is still changing and not stable, farmers can add dolomite lime.

2. Brownish Green

When pond water is green-brown, it means that the water contains sufficient phytoplankton. This color is the best color for vannamei shrimp pond. However, to maintain its stability, it is necessary to apply fertilizer every week.

3. Blue Green

The bluish-green color in vannamei shrimp ponds indicates abundant blue-green algae phytoplankton. This shows that there are porous shrimp, and it is necessary to replace the water, add dolomite lime, and apply TSP fertilizer.

4. Dark Green But Not Concentrated

The color of pond water is dark green, indicating that the amount of phytoplankton in the water is relatively stable. This color is the best water color for vannamei shrimp pond. Meanwhile, to optimize it, farmers can give a little TSP fertilizer while continuing to observe if there is any changes.

5. Deep Dark Green

When pond water is thick dark green, and feels slimy, this indicates that there is toxic phytoplankton which can cause many shrimp to get sick. Of course, this color is not the best color for vannamei shrimp pond and farmer must avoid it.

But there is no need to worry about overcoming this can be done by replacing water and giving dolomite lime.

6. Dark Brown

The dark brown color of pond water indicates a lack of phytoplankton growing in it. To overcome this, urea and TSP fertilizers can be used, and further land reclamation is needed.

7. Reddish Brown

When the color of the pond water is reddish brown, this indicates a high content of toxic phytoplankton and sulfuric acid. To deal with this, you need to neutralize it by changing the water, giving lime, giving urea fertilizer, and rinsing the pond repeatedly.

8. Black

The black pond water color indicates that the phytoplankton is not growing properly. In addition, this color can also be an indication of the amount of decaying organic matter at the bottom of the pond. Of course, this color is not the best water color for vannamei shrimp pond.

The only way to overcome this condition is to remove the sludge that has settled at the bottom of the pond until it runs out.

Indicators of Pond Water Quality

Knowing the quality of pond water is an important thing that must be done every day. This is to make it easier if there are changes or anomalies, farmers can take steps as quickly as possible.

Not only observing the color of pond water which is suitable for vannamei shrimp but there are also other indicators that must be monitored regularly every day. The following are the indicators:

1. Pond Water Color

As previously explained, the color of pond water indicates the quality of the water in it. The best color for vannamei shrimp pond is dark green without slime and light brown.

2. Pond Water Brightness

Good pond water brightness ranges from 25-60 cm. Meanwhile, the brightness number is below it. In that case, it is difficult for sunlight to penetrate the water, resulting in low water temperatures and the photosynthesis process not running optimally.

3. Pond Water pH

pH is the level of acidity of water that is measured physically and greatly affects the organisms that live in it. The ideal pond water pH ranges from 7.5-8.5. Changes in pH in vannamei shrimp ponds can cause shrimp to become stressed. Therefore, it is vital to keep the pH ideal.

4. Dissolved Oxygen

Dissolved oxygen, also known as DO, supports shrimp in the respiration process. This indicator also dramatically affects the growth of shrimp. Usually, to keep the DO stable, aerators are used according to the needs of each pond.

5. Water Temperature

The ideal pond water temperature ranges from 28-31 degrees Celsius. Farmers must maintain this perfect temperature to remain stable every day. This is because temperatures that decrease or increase drastically can cause the death of shrimp in large enough numbers.

6. Pond Water Alkalinity

A good level of alkalinity concentration for vannamei shrimp is 130-180 ppm. This alkalinity is the ability of water to neutralize additional acids without lowering the pH level of the water. Alkalinity indicators need to be monitored regularly because they directly affect the growth of shrimp and supporting microorganisms in pond ponds.

7. Water Salinity

The ideal pond water salinity ranges from 15-25 ppt. This salinity condition must be maintained to remain stable. This is because less salinity can result in less optimal shrimp growth. In addition, too fast fluctuations in salinity can also cause stress in shrimp and can trigger death.
