Probiotics/Feeds

Enhancing Shrimp Farming: The Role of Synbiotics in Boosting Health, Growth, and Disease Resistance in Litopenaeus vannamei

The Pacific white shrimp (Litopenaeus vannamei) is a dominant force in the aquaculture industry, accounting for a substantial 52.9% of global production. Nonetheless, shrimp farms face significant challenges due to diseases caused by various microorganisms. Given the current disease threats, it is crucial to prioritize and implement effective disease management strategies in order to maintain the long-term viability and financial success of shrimp farming operations.

A highly intriguing solution that has captured significant attention is the incorporation of synbiotics as feed additives. Combining probiotics and prebiotics into synbiotics provides a wide array of advantages that go beyond what probiotics or prebiotics can offer individually. Prebiotics are essential for optimizing the success of these treatments as they support the survival and colonization of probiotics in the shrimp’s gut, thereby maximizing their overall effectiveness. This symbiotic connection contributes to the maintenance of a balanced and thriving intestinal ecosystem, which plays a crucial role in promoting shrimp’s overall health.

Extensive research has shown that certain bacteria can have a positive effect on shrimp growth, as well as help prevent the spread of harmful microorganisms and maintain a stable intestinal environment. Both controlled experiments and real-life situations consistently observe these beneficial outcomes. Prebiotics play a crucial role in maintaining a healthy gut microbiome in shrimp, promoting the growth of beneficial bacteria, and suppressing harmful bacteria. This balance is critical for the shrimp’s overall health.

Integrating synbiotics into shrimp diets can result in better growth performance, improved feed utilization, enhanced disease resistance, increased nutrient digestibility, and a boosted immune system. Research has indicated that the inclusion of synbiotics in dietary supplements can have a positive impact on the growth, intestinal health, and immune response of shrimp. These discoveries indicate that synbiotics could greatly transform the shrimp farming industry by enhancing overall health and disease resistance, making them a valuable asset to contemporary aquaculture methods.

Understanding Shrimp Nursery and Its Benefits in Aquaculture

Shrimp nursery is one of the methods used to assist in the growth of shrimp larvae into juveniles (called “benur”) ready for aquaculture. This method offers several benefits, especially in reducing stress levels among benur when they are transferred to cultivation ponds.

Nursery plays a crucial role in helping shrimp adapt to pond environments. Vannamei shrimp, in particular, naturally inhabit brackish waters. Moreover, undenurtured shrimp larvae often struggle to adapt and have higher mortality rates.

For those interested in trying vannamei shrimp nursery, here are the steps:

What is Shrimp Nursery?

Shrimp nursery involves the process of growing shrimp larvae into post larvae. The aim is to increase the survival rate of post larvae released into ponds. Additionally, vannamei shrimp nursery helps farmers obtain uniformly sized and high-quality shrimp.

Successful Shrimp Nursery Techniques

1. Prepare the Nursery Environment and Fill with Water

The first step involves preparing the nursery environment and filling it with water. An ideal nursery pond is rectangular and made of concrete. Ensure rounded corners to prevent debris buildup and facilitate water circulation. Before use, the pond should be cleaned, dried, and equipped with aeration systems and blowers for oxygenation.

For water filling, seawater is recommended. Ensure the pond is dry and the installation system is in place before filling. Water is added through an inlet pipe equipped with filters to remove any remaining impurities. Once filled with seawater, add sodium or EDTA (Ethylene Diamine Tetraacetic Acid) at 10 ppm for larval maintenance.

2. Release the Post Larvae

During the nursery phase, the shrimp larvae placed in the pond are nauplii. Before placement, nauplii need to acclimate for 15 minutes to adjust to the pond water temperature.

3. Feeding

At this stage, it’s crucial to pay attention to the type, dosage, and frequency of feeding. Larvae can be fed natural or artificial feeds, but nauplii should preferably be fed natural feeds as they still have their yolk sacs as food reserves. Artificial feeds are only necessary when larvae develop into zoea within 40 hours, requiring fine particles that larvae can consume. Phytoplankton should only be provided up to the mysis stage, then replaced with artemia at the post larvae stage. Feeding doses should be adjusted according to larval stages to maintain health and growth.

4. Proper Water Management

At this stage, regular water exchange in the pond is crucial. Without exchange, leftover feeds and feces can threaten larval health. Water exchange aims to maintain stable water parameters such as temperature, salinity, and pH, preventing stress in larvae due to sudden changes in water conditions.

5. Harvesting Post Larvae Carefully

Harvesting post larvae is done after passing stress tests, salinity tests, and being declared free from diseases and luminescent bacteria. The harvesting process begins by draining 40% of the pond water, installing nets, and opening water channels. Post larvae are caught using harvesting nets, then transferred to buckets filled with water at 28 degrees Celsius. After this process, post larvae are ready for cultivation in ponds by the farmers.

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.

Types of Vaname Shrimp Feed

1. Natural Feed

pakan udang vaname — Source: Australian.museum

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

vannamei shrimp feeds — Source: Freepik.com/racool_studio

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)

Effect of Water pH on Vannamei Shrimp Cultivation

Vannamei Shrimp is one of the world’s most popular cultivated shrimp species. This shrimp is known for its high growth rate and great taste. However, the growth of vannamei shrimp is also influenced by pond water quality parameters, one of which is pH.

pH measures a solution’s degree of acidity or alkalinity on a scale of 0 to 14. The pH of pond water in good Vannamei shrimp farming ranges from 7.5-8 in the morning and 8-8.5 during the day.

So, what if pond water’s pH could be more optimal? Read more in the following article.

Also Read: These are 11 Characteristics of Healthy and Diseased Shrimp

What is pH?

pH is a measure of the acidity or alkalinity of a solution indicated by a logarithmic scale ranging from 0 to 14. pH 7 indicates a neutral condition, a pH less than 7 indicates an acidic condition, while a pH greater than 7 indicates an alkaline state.

How to Check pH

You need a pH test kit, such as pH indicator paper, to determine the pond’s pH in Vannamei shrimp farming. Here are the steps for measuring pH using pH indicator paper or a pH meter that you can follow:

Collect a sample of the shrimp pond water in a clean container.
Dip the pH indicator strip into the water sample or use a pH meter to measure the pH value directly.
Wait for the pH indicator strip to change color or for the pH meter to stabilize its reading.
Match the color of the pH indicator strip to the color chart or read the pH value that appears on the pH meter.
Record and compare the pH measurement results with the optimal pond pH range for Vannamei shrimp farming.
If the pH is outside the optimal scope, take the necessary steps to adjust it.

Effect of Water pH on Vannamai Shrimp Cultivation

The pH level of pond water can significantly impact shrimp’s health and growth. A pH level that is too low or too high can cause stress on the shrimp, thereby reducing the growth rate and making it more susceptible to disease.

The low pond water’s pH can also cause the shrimp skin to become porous and soft due to the disruption of changing new skin. Also, shrimp can die if the pond water pH is < 4 or > 11.

Therefore, maintaining pH stability in the ideal range is very important for the success of Vannamei shrimp culture. This can be achieved by regularly monitoring water quality and using buffers or other pH adjustment treatments.

How to Maintain Optimal pH for Vannamei Shrimp?

Maintaining optimal pH stability in Vannamei shrimp culture requires regular monitoring and adjustment of water conditions. Here are some things you can do to maintain pH stability to keep it optimal:

1. Routine Monitoring

pH stability must be monitored regularly using a pH meter or pH indicator paper to ensure that conditions are in the optimal range for the growth of Vannamei shrimp.

2. pH adjustment

If the pH level is too low, it can be adjusted by adding a base such as sodium bicarbonate. Meanwhile, if the pH level is too high, it can be lowered by adding molasses.

3. Water Change

Regular water changes can also help maintain a stable pH level where waste products from shrimp farming that can change the pH concentration are also removed.

4. Avoid Overfeeding

Overfeeding can lead to a higher accumulation of waste products and decreased pH levels. Ensure you feed the right amount and immediately clean up the leftover feed that doesn’t run out.

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.

Also Read: 4 Types of Vannamei Shrimp Harvest Time

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.

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.

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.
