Causes and Ways to Overcome Stress in Vannamei Shrimp

Stress in vannamei shrimp is a common problem in aquaculture that can harm growth, health, and shrimp production. What’s more, this shrimp is susceptible to stress due to its sensitivity to environmental changes.

Vannamei shrimp is one of the most widely cultivated species worldwide due to its fast growth rate, high survival rate, and disease resistance.

However, farmers often face the challenge of stress on their shrimp, which can lead to reduced growth rates, decreased survival, and increased susceptibility to disease.

Therefore, we will discuss more deeply how to stress vannamei shrimp. Including the signs and how to overcome them.

Causes of Shrimp Stress

1. Water quality

Poor water quality, including low oxygen levels, high ammonia and nitrite levels, to pH fluctuations, can cause stress for vannamei shrimp during cultivation.

2. Handling and Transportation

Handling and moving shrimp that are rough and not according to standards can also cause stress to the shrimp. This is because shrimp are sensitive to external stimuli, such as shock, exposure to too high a temperature, and overcrowding.

3. Environmental factor

Shrimp are sensitive to sudden environmental changes. Examples include rapid changes in light, temperature, and salinity. This sudden change can be a stress-causing factor for vannamei shrimp.

4. Inappropriate Feed and Nutrition

Poor or inadequate feed quality can cause stress to shrimp. This is because feed with poor quality can cause shrimp to experience an imbalance in the nutrients, vitamins, and minerals they get.

Signs of Stressed Shrimp

Farmers must continue to monitor shrimp during cultivation for signs of stress to prevent a more significant impact of losses. Here are some common symptoms of stress on vannamei shrimp:

  1. Appetite and eating activity is reduced
  2. Reduced activity and behavior become sluggish
  3. Shrimp mortality rate increases
  4. Abnormal swimming behavior, such as swimming in circles and darting.
  5. Poor growth rate
  6. Color change in the shrimp body

Impact of Stress on Shrimp

Stress in shrimp has a significant impact on shrimp health and growth. That is why farmers must constantly monitor the condition of the shrimp so they don’t experience stress during cultivation.

1. Lowering Shrimp Immunity

Stress can have a direct impact on the shrimp’s immunity. To be precise, it can significantly lower the immune level. This makes the shrimp more susceptible to disease and infection.

2. Reduced Growth

Stress can indirectly inhibit the growth of vannamei shrimp during cultivation. Stressed shrimp tend to have a disturbed diet, so not as many nutrients are absorbed.

3. Increasing Mortality Rate

Severe or prolonged stress can increase mortality among pond shrimp populations.

4. Behavior Change

Changes in behavior also have a direct impact when the vannamei shrimp are stressed. These changes include decreased activity levels and changes in diet.

How to Overcome Stress Shrimp

Preventing and managing stress in vannamei shrimp requires careful monitoring and management of environmental and physiological factors. Here are some ways to deal with stress on vannamei shrimp:

1. Monitor Water Quality Regularly

Monitoring water quality parameters regularly can be a way of preventing stress on vannamei shrimp. This is because optimal water parameters are the best environment for growing shrimp.

Therefore, regularly check water quality parameters such as temperature, pH, salinity, and dissolved oxygen levels, and make adjustments in case of fluctuations to maintain optimal conditions.

2. Give Enough Nutrition Shrimp

Adequate nutrition can make shrimp grow optimally and avoid stress. Ensure to provide balanced nutrition in feed and probiotics to support shrimp growth.

3. Adjust Stocking Density with Pond Capacity and Cultivation Type

Vannamei shrimp stocking densities that are excessive and not under pond capacity can cause stress to the shrimp. Because shrimp will compete with each other to get food and space for movement.

4. Shrimp Acclimatization

The last way to prevent stress on vannamei shrimp is to acclimate the shrimp gradually to changes in water quality parameters.

Partial Harvest of Vannamei Shrimp and Its Benefits to Increase Profits

Partial harvest of vannamei shrimp is something that farmers often do to maximize profits during cultivation, especially for those who implement semi-intensive, intensive super-intensive cultivation systems.

Vannamei shrimp is a species that is popular and most sought after by the global market. This shrimp has a fast growth rate and is suitable for aquaculture, so farmers widely choose it.

In order to maximize profits and ensure sustainable cultivation, farmers need to be aware of the benefits of partial harvesting. Let’s read more of these benefits in this article.

Also Read: These are 7 Tips for Successful and Profitable Vannamei Shrimp Harvest

What Is Partial Harvest?

Partial harvest is a technique for harvesting only a portion of the shrimp in the pond, allowing the rest to grow and develop. This harvesting technique can be done several times in one cultivation cycle, allowing farmers to manage their harvests and maximize profits.

Partial harvesting is a common technique used in vannamei shrimp farming to help regulate population densities and ensure consistent growth rates. By doing partial harvests, farmers can prevent overcrowding which can lead to stunted shrimp growth, disease outbreaks, and reduced survival rates.

Shrimp Partial Harvest Preparation

Before carrying out a partial harvest in vannamei shrimp farming, you must carefully prepare and plan for a successful harvest. Here are some preparatory steps you can take:

1. Determine the Optimal Harvest Size

Farmers must determine the ideal size for harvesting shrimp based on demand and market prices. This will help ensure the harvested shrimp can be sold at the most profitable prices.

2. Check the Water Quality

Farmers should check water quality parameters such as temperature, salinity, dissolved oxygen, etc., to ensure they are within the appropriate range for shrimp. If water quality parameters are less than optimal, farmers must first adjust them.

3. Prepare Harvest Equipment

The following partial harvest preparation that must be done is to prepare the equipment for harvesting. Farmers must ensure that all necessary equipment, such as nets, pumps, and baskets to accommodate harvested shrimp, is available. In addition, it must also be assured that all equipment is clean and working correctly.

4. Transportation Preparation

Farmers also have to prepare transportation for harvested shrimp. This ensures the shrimp are transported quickly and efficiently to the processing site.

Partial Harvest Process

Partial harvesting usually uses nets to take 30% of the total shrimp population in the pond. After that, the shrimp are typically put in a container that has been prepared on the side of the pond.

The harvesting process involves placing nets at the bottom of the ponds, spreading the feed, and waiting a few moments for the shrimp to approach the nets to harvest them. This method is quite effective to do.

Harvesting usually starts at night, when the shrimp swim more freely. Feeding should be stopped a few hours before harvest. The process includes the following steps: turning off the aerator near the trap, lowering the net to the bottom of the pond, spreading a few handfuls of feed over the net area, and then waiting about 3-10 minutes.

Pull the net using the rope tied at the corners when a lot of shrimp are trapped. However, it is necessary to ensure that the number of shrimp caught is at most 30% of the total population in the pond.

Benefits of Partial Harvesting Vannamei Shrimp

Partial harvesting is a technique that harvests only a portion of the shrimp in the pond, leaving the rest to grow to a specific size. This harvest can be done several times during the production cycle, allowing farmers to maximize profits.

One of the main benefits of partial harvesting is that it allows farmers to take advantage of fluctuations in the price of vannamei shrimp on the market. By harvesting only a portion, farmers can manage sales to coincide with periods when shrimp prices are rising.

Partial harvests can also help farmers reduce production costs. Farmers can avoid the costs associated with harvesting and processing large quantities of shrimp all at once by only harvesting a portion at a time. This includes labor, equipment and transportation costs.

Apart from the economic side, partial harvest is also beneficial from the health side of the shrimp. By allowing some of the shrimp in the pond to continue to grow, farmers can help maintain a healthy ecosystem. This can help farmers reduce the risk of disease outbreaks and other problems during farming.

Disease

Getting to Know the Taura Syndrome Virus (TSV) in Vannamei Shrimp

Taura Syndrome Virus (TSV) is a highly contagious disease affecting shrimp aquaculture worldwide. This disease can cause death up to 40-90% in post-larvae and juvenile stages.

The Taura Syndrome virus was first identified in 1992 during an outbreak that caused economic losses in Ecuador. Since then, TSV disease has become a significant concern in the aquaculture industry.

So, what are the signs that shrimp are infected with Taura Syndrome Virus (TSV), and how is it treated? Come on, find out more in this article.

Also Read: 7 Types of Shrimp Diseases that Often Occur During Cultivation

What is TSV?

Taura Syndrome Virus (TSV) is a disease of vannamei shrimp caused by an infectious virus that affects shrimp farming in various parts of the world. The disease caused by this virus first appeared in Ecuador in 1992. However, it later spread to Asian regions by importing infected fry and broodstock.

TSV is classified as a small icosahedral virus that belongs to the virus family called Dicistroviridae. This virus has a single-stranded RNA genome of about ten kilobases.

The Taura Syndrome virus infects the hepatopancreas, the digestive gland of the shrimp, and causes severe necrosis, which results in the death of organ function. This virus can also cause gill discoloration, lethargy, and mass death.

Transmission of Taura Syndrome Virus

Taura Syndrome Virus (TSV) is transmitted through water, infected shrimp and contaminated equipment. This virus can also be transmitted vertically from infected broodstock to the resulting fry.

In addition, shrimp that have been infected with TSV can still be carriers of the virus for the rest of their lives. Migratory birds, aquatic insects, and humans can also be a route for transmission of this virus.

The Taura Syndrome Virus can also infect through the excrement of seagulls that previously ate shrimp infected with this virus.

Symptoms of TSV in Vannamei Shrimp

Vannamei shrimp that are attacked by TSV usually show more than one symptom. Here are some common symptoms:

  1. Shrimp become lethargic
  2. Decreased appetite
  3. The prawns gathered at the edge of the pond when they were almost dead
  4. High and sudden death rates in post larvae and juvenile shrimp.
  5. The shrimp’s stomach is empty, and the shrimp’s body is pale red
  6. Fan tail and shrimp pleopods are red
  7. Shrimp shells softened
  8. There are dark spots that are randomly distributed on the cuticle of the shrimp.

How to Detect TSV Disease

Detection of Taura Syndrome Virus (TSV) disease can be done by PCR (Polymerase Chain Reaction) method, gross pathology, in situ hybridize, and bioassay. However, detection by PCR (Polymerase Chain Reaction) is the most accurate method that can be done.

Examination by the PCR method consisted of three stages, namely extraction of DNA/RNA samples for preparation of prints, DNA/RNA amplification with the help of a PCR machine (thermocycler) and analysis of the amplification results by electrophoresis, DNA/RNA staining and documentation with a Polaroid camera.

Control and Treatment

Until now, no vaccine is available to prevent transmitting this TSV disease. The precautions that farmers can take at this time is to control its spread.

One of the most effective preventive measures is to ensure the use of broodstock and frying free of the Taura Syndrome Virus (TSV). In addition, regular testing of shrimp populations and strict biosecurity measures can also help reduce the risk of infection.

Tips on Taking Care of Shrimp Ponds During the Rainy Season

Taking care of shrimp ponds during the rainy season is the biggest challenge for farmers during cultivation. High rainfall is very risky for ponds because it can disrupt the balance of water parameters, directly impacting the health and productivity of shrimp ponds.

To ensure the long-term sustainability and profitability of shrimp farms, farmers must have a solid understanding of best practices for managing shrimp ponds during the rainy season.

In this article, we will discuss some tips and strategies on taking care of shrimp shrimp ponds during the rainy season so farmers can minimize risks and maximize aquaculture productivity.

Also Read: 7 Types of Shrimp Diseases that Often Occur During Cultivation

The Impact of the Rainy Season on Vannamei Shrimp Cultivation

The water quality parameter is the primary indicator of the success of vannamei shrimp cultivation. Optimal water quality can make vannamei shrimp farming a great success. On the other hand, poor and drastically changing water quality can cause vannamei shrimp to become stressed and susceptible to disease.

Following are some of the impacts of the rainy season on vannamei shrimp cultivation:

1. Temperature Changes

When it rains, pond water temperatures can drop to 2-3°C. Low temperatures make water conditions less than optimal, impacting metabolic rates and making shrimp activity slower, and they tend to gather at the bottom of the pond.

Not only has an impact on shrimp, but the activity of decomposing bacteria also decreases when the pond temperature is not in optimal conditions. This causes the accumulation of organic matter present in the ponds

2. Decrease in pH

Rain pH is usually around pH 6.5-7.0. Rain will directly lower the pH by 0.3-1.5 shortly.

3. Changes in Salinity and Alkalinity.

Rain can cause pond water to become thinner, so the salinity and alkalinity numbers also go down.

When the salinity drops, the shrimp will molt. However, the limited availability of minerals can lead to disease infection and cannibalism among shrimp.

4. Plankton Population and Organic Matter Accumulation

The impact of the rainy season on vannamei shrimp cultivation is the death of phytoplankton due to changes in water quality parameters. The dead phytoplankton will also accumulate as organic matter at the pond’s bottom.

The rainy season also makes the shrimp’s diet abnormal and tends to be lower. Therefore, the remaining feed will be more, and the processing is also slower and causing the accumulation of organic matter to increase.

5. Decreased Shrimp Immunity Level

Changes in water quality parameters due to rainwater can cause the ecosystem where shrimp live to become unstable. In addition, sudden changes can cause shrimp to become stressed, and experience decreased immunity, making them susceptible to disease infections.

Tips for Taking Care of Shrimp Ponds During the Rainy Season

1. Proper Pond Preparation

Preparing a proper pond is very important to maintain the health of the shrimp pond during the rainy season. Shrimp farmers must ensure that their ponds are cleaned properly and free of waste and impurities before the rainy season arrives.

In addition, it is necessary to construct suitable drainage channels and install pumps to drain the sewage to control the water level.

2. Maintaining Optimal Water Quality

Water quality is essential for successful cultivation, especially when the rainy season arrives. Excessive rainfall can cause a decrease in optimal conditions for pond water quality parameters.

Therefore, farmers must continue to monitor water quality regularly and take appropriate action when the rainy season comes, for example, by adding an aerator, adjusting the pH and salinity levels, reducing the frequency of feeding, and maintaining optimal water conditions.

3. Disease Management

Tips for taking care of shrimp ponds during the next rainy season are good disease management. During the rainy season, the growth of microorganisms, including bacteria and viruses, increases. This can cause shrimp to be susceptible to disease.

Farmers must take preventive measures, such as disinfecting ponds and equipment, implementing good hygiene and biosecurity protocols, and always monitoring for signs of shrimp disease.

4. Adjust Feeding

Feed management is an important aspect that must be considered when caring for shrimp ponds during the rainy season, where farmers must adjust their feeding schedule based on weather conditions and pond water quality.

Overfeeding can lead to poor water quality and increase the risk of disease. While giving less feed can inhibit the growth of shrimp.

In addition, make sure the feed given is of high quality and free from pathogenic contamination.

5. Always Monitor Weather Conditions

The last tip on taking care of shrimp ponds during rainy season is always to monitor weather conditions. Rainfall sometimes cannot be predicted precisely and accurately, so farmers must prepare what actions to take when it rains.

Some things that can be done include closing the pond and reducing the feed. In addition, always be alert for signs of flooding that can cause water quality problems and damage pond infrastructure.

Benefits of Molasses and Tips on Using It for Shrimp Ponds

The benefits of molasses for shrimp ponds are one of the things that farmers must know. Molasses is a thick black liquid that is a by-product of the sugarcane-based processing industry.

In vannamei shrimp farming, the benefits of molasses for shrimp ponds can be seen from its role in accelerating plankton growth. Meanwhile, plankton is a natural food source for vannamei shrimp during cultivation.

Not only in vannamei shrimp cultivation, several ruminant and poultry farms also use molasses as a feed mixture. So what exactly is molasses, and what are its benefits? Come on, see more in this article.

Also Read: This is the Difference between Male and Female Shrimp

What is Molasses?

Molasses is a by-product derived from processing granulated sugar made from sugarcane. In a way, molasses is a production waste that benefits livestock and fisheries the most.

Among farmers and ranchers, molasses is often referred to as molasses. Meanwhile, its benefits are no longer in doubt because ruminant and poultry breeders have been using it as a feed mixture for a long time.

In vannamei shrimp farming, molasses is used as a source of growth for heterotrophic bacteria in making vannamei shrimp probiotics. Because, molasses can serve as a carbon source that becomes food for bacteria.

Benefits of Molasses for Shrimp Ponds

In contrast to poultry farming, the benefits of molasses for shrimp ponds cannot be given directly as a food supplement. Instead, molasses is used as a food source for bacteria which will later become natural food for vannamei shrimp.

In addition, probiotics produced from molasses fermentation are also useful in improving pond water quality, increasing the growth rate of vannamei shrimp, preventing pathogenic bacteria from growing in pond water, and reducing the feed conversion rate (FCR).

Tips for Using Molasses for Shrimp Ponds

The benefits of molasses for shrimp ponds can be obtained if the molasses is given in the right dosage. Here are tips on using molasses for shrimp ponds.

1. Pay Attention to the Quality of the Molasses

Before providing molasses for shrimp ponds, it is important to ensure that the molasses you use is of good quality. Be sure to check the color and smell of the molasses first. Darker, stronger-flavored molasses tends to be of better quality.

In addition, make sure the molasses is free from contamination or impurities that can harm your vannamei shrimp.

2. Make sure the dosage of molasses is right.

The dose of molasses also must be done appropriately. To grow probiotic bacteria, molasses is needed at a dose of 2-5% of the total feed used.

While the addition depends on the pH of the water. If the pH is less than 7.5, giving molasses can be reduced. Meanwhile, if the pH is more than 8, then the use of molasses is added.

3. Monitor Water Quality Routinely

Molasses can increase the need for dissolved oxygen (DO) in water, affecting water quality in ponds. Therefore, monitoring water quality regularly is important and ensuring that dissolved oxygen (DO) levels are always optimal and sufficient for the shrimp.
