Intensive Vannamei Shrimp Cultivation, How to Do It?

Intensive vannamei shrimp cultivation is increasingly being chosen by farmers because of its higher productivity and profitability. But on the other hand, the risks encountered during cultivation are also higher.

In an intensive system, vannamei shrimp cultivation, high technology and capital are needed. Starting from feed that completely relies on artificial feed, using aerators to maintain dissolved oxygen levels, and so on.

Although it requires high capital and technology, the profitability of intensive system cultivation is also high. This is what makes intensive vannamei shrimp cultivation chosen by many farmers.

So, how to do it? Check out the full explanation in this article.

Method of Intensive System Vannamei Shrimp Cultivation

1. Pond Preparation

Intensive vannamei shrimp cultivation is carried out by spreading fry in large numbers in a relatively small area and a controlled environment. So that farmers must prepare everything appropriately and according to standards so that shrimp can grow optimally, one of which is pond land.

Land preparation is the first step that farmers must take before cultivation. Some of the land preparations for intensive vannamei shrimp cultivation include:

  • Water treatment in the main reservoir.
  • Pond construction improvement.
  • Pond bottom processing which includes drying and liming.
  • Installing plastic mulch.
  • Water filling to a depth of 10 cm.
  • Extermination of pests and pathogens.
  • Water filling up to 70%.
  • Plankton growth.
  • Growth of probiotic bacteria.

2. Spreading Vannamei Shrimp Seeds

The next step for intensive vannamei shrimp cultivation is spreading fry. The number of fries stocked is usually adjusted to each farmer’s production target and the pond’s area.

Vannamei shrimp fry will be stocked after the water quality parameters are optimal. Usually, the fry will be stocked in the morning or at night to avoid stress due to significant environmental differences.

3. Maintenance

In the daily maintenance of intensive vannamei shrimp farming, it is necessary to routinely control water quality parameters and feed and adjust the use of aerators in pond ponds.

The frequency of feeding vannamei shrimp must be adjusted to the shrimp consumption and growth rate. This is useful so that the FCR number remains optimal. Meanwhile, control can be done through anco from each pond.

4. Pest and Disease Control

Disease control in vannamei shrimp cultivation should be carried out with preventive or preventive measures before the disease infects the shrimp. Preventive actions can be carried out by applying biosecurity and immunostimulants.

Meanwhile, disease detection is usually done by observing the body morphology of the shrimp and conducting PCR (Polymerase Chain Reaction) tests in the laboratory periodically.

5. Harvest

The intensive system vannamei shrimp harvest occurs when the shrimp are over 100 days old or have reached a certain weight and size. However, in an intensive system of vannamei shrimp, partial harvest is carried out to reduce the density of the shrimp.

Apart from partial harvests, other types of harvests are usually carried out by farmers, namely normal harvests, abnormal harvests, and emergency harvests.

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.

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.

Vannamei Shrimp Stocking Density and How to Calculate It

One important aspect of aquaculture is determining the optimal vannamei shrimp stocking density. This can be done to consider the number of shrimp that can be accommodated from start to harvest in the pond that has been prepared.

Stocking density plays an important role in the success of aquaculture because excess density can cause poor water quality, disease attacks, and stunted shrimp growth in ponds.

In addition, shrimp stocking densities that are too high can also increase competition for food and space. So, what is the ideal stocking density for traditional, semi-intensive, intensive, and super-intensive ponds? Read more in this article.

Also Read: Vannamei Shrimp Salinity and How to Control Its Stability during Cultivation

Why is it Important to Consider Stocking Density?

Farmers must consider the stocking density of the vannamei shrimp they will choose before starting cultivation. This is because stocking density directly affects the growth and quality of the cultivated vannamei shrimp.

There are several other reasons why it is important to consider the stocking density, including:

1. Ensuring Optimal Shrimp Growth and Health

Traditional and intensive vannamei shrimp stocking densities significantly impact the growth and health of vannamei shrimp. Overcrowding can lead to poor water quality, increased competition for food and space, and increased risk of disease outbreaks.

Calculating the stocking density of vannamei shrimp and adjusting it to pond conditions ensures it can grow and develop optimally.

2. Maximizing Cultivation Results

Intensive vannamei shrimp stocking density is closely related to the cultivation results obtained later. The density that is too low in large ponds is the same as not utilizing available resources efficiently, so the yields are not optimal.

Conversely, a density that is too high and does not match the capacity of the pond can cause an increase in mortality and a decrease in growth rates. Therefore, by calculating the stocking density and adjusting it according to needs, farmers can maximize the potential of their ponds.

3. Cost Effectiveness

Vannamei shrimp cultivation is a lucrative business because the profits are very abundant. However, like business, this abundant profitability must be accompanied by cost-effective use during the cycle.

Calculating the stocking density of vannamei shrimp is one way to help cultivators determine capital and maximize their profits from this cultivation.

Too high density can lead to increased mortality, decreased growth rates, and increased FCR numbers. This will also impact increasing costs and reducing profits when the harvest arrives.

4. Disease Management

The density of vannamei shrimp directly affects the risk of disease outbreaks during cultivation. Pond ponds that are too dense can affect water quality, triggering disease outbreaks over time.

By calculating stocking densities and maintaining them at optimal levels, farmers can reduce the possibility of disease outbreaks and minimize the need for expensive shrimp health care.

5. Environmental Sustainability

Vannamei shrimp cultivation can cause significant environmental impacts, especially in intensive and super-intensive cultivation types that must be carried out sustainably.

The more shrimp cultivated in the pond, the more dirt and food scraps are produced during cultivation. Dirt and food scraps can turn into chemical compounds that harm the environment.

Therefore, by calculating the stocking density and maintaining it at an appropriate level, farmers can minimize the negative impact on the environment that may occur.

How to calculate the stocking density of Vannamei Shrimp

Calculating the stocking density of vannamei shrimp requires careful measurement and accurate recording. This is so that your cultivation can bring maximum profit and avoid losses.

Then, how to calculate the stocking density of vannamei shrimp? Here are the steps.

Calculate the Capacity of the Pond 

The first step you have to take is to calculate the pond capacity that will be used for vannamei shrimp cultivation. How to calculate the area of a vannamei shrimp pond can be measured using a measuring tape or other measuring device.

If the pond you have is rectangular, you can use the volume formula as follows:

Volume = pond length (meters) x pond width (meters) x pond depth (meters)

For example, if you have a pond with a length of 10 meters, a width of 5 meters, and a depth of 3 meters. Then the capacity of the pond = 10 x 5 x 3 = 150 cubic meters.

After knowing the capacity of your vannamei shrimp pond, choose a stocking density following this capacity.

However, if you already know the area of the pond that you have for sure, you can immediately follow the second step, namely calculating the stocking density of vannamei shrimp.

Calculate the Stocking Density of Vannamei Shrimp

Vannamei shrimp stocking density depends on the cultivation method used. For example, use traditional, semi-intensive, intensive, or super-intensive cultivation methods.

The formula for total stocking density = pond area (square meters) x stocking density per meter

This total stocking density is usually used for calculating the amount of feed, aerators, and other pond needs.

The stocking density of vannamei shrimp in traditional ponds is usually a little, which is around 5-8 PL per square meter. If your pond is 100 square meters in area, then 100 x 5 = 500 shrimp fry that can be stocked in the pond.

While in intensive ponds, the stocking density of vannamei shrimp tends to be higher. The stocking density of intensive ponds is above 100 per square meter. At the same time, the calculation formula must also be adjusted to the number of wheels and aerators used.

5 Tips on Managing Vannamei Shrimp Ponds

Success when cultivating always depends on our way of managing vannamei shrimp ponds. Both in terms of technical and non-technical factors. Therefore, farmers need to have good pond planning and management.

This method of managing shrimp ponds also directly affects harvest productivity. Thus, many factors must be considered in vannamei shrimp farming, such as human resource factors, feed management, shrimp health management, and the harvest process.

Here we have summarized some tips on managing shrimp ponds, especially for you, so that the harvests are as expected.

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

Ideal Shrimp Pond

Talking about the ideal shrimp pond, the first thing that comes to your mind is how it is constructed. This is because construction has an important role in the sustainability of shrimp ponds.

So, here are the criteria for ideal shrimp ponds regulated in the Ministry of Maritime Affairs and Fisheries Regulation No. 75/PERMEN-KP/2016 concerning General Guidelines for Enlargement of Tiger Shrimp (Penaeus Monodon) and Vannamei Shrimp (Litopenaeus Vannamei).

  1. Have sufficient water availability.
  2. Ponds do not have dead spots.
  3. Effective and efficient in the use of land and mills.
  4. The bund as an access road in the pond must be passable by vehicles and workers.
  5. Guaranteed maximum security and safety (K3).

If you have fulfilled the five criteria based on the Minister of Maritime Affairs and Fisheries Regulation No. 75 of 2016 above, you can then select the ideal pond location. Some of the criteria for an ideal pond location include the following:

  1. The location of the shrimp ponds is under the Regional Spatial Plan (RTRW) and applicable regulations.
  2. The location of the new shrimp ponds above/behind the shoreline (100 meters from the highest tide point) and the riverbank.
  3. Having sufficient and good quality source water.
  4. Located in an area protected from routine flooding and the influence of toxic and hazardous waste (B3) pollution.
  5. Do not build new ponds on mangrove land and the core zone of the conservation area.
  6. Do not build shrimp ponds in areas where saltwater seepage has the potential to affect surrounding agricultural areas or freshwater sources.
  7. Adequate transportation and communication infrastructure is available.

Tips for Managing Shrimp Ponds

1. Choose the Right Pond Lining

The pond bottom lining is important to ensuring biosecurity during shrimp farming. Ground ponds directly exposed to water can trigger anoxic reactions, which are highly toxic to shrimp. Therefore, coatings such as high-density polyethylene (HDPE) plastic or concrete can be a solution.

In addition to biosecurity issues, using HDPE concrete and plastic layers also makes it easier to manage water and pond bottoms.

2. Consider Pond Design

The design of the vannamei shrimp pond has various shapes, including rectangular, square and round. This pond’s shape has advantages and disadvantages, as well as an effect on water flow and pond sediment accumulation.

While at the bottom of the pond can be designed with a central channel to minimize sedimentation. It works by utilizing the sedimentation and centrifugal currents generated by the aerator to push and concentrate the solids that settle in the middle of the pond.

Then, these solids can be manually pumped out of the pond through a pumping system connected to the sewer.

3. Place the Pond Aerator Properly

In intensive system vannamei shrimp farming, the aerator plays an important role in providing oxygen while helping to push sludge into the sewer. While the type and number of aerators can be adjusted to the needs of each pond based on pond size and stocking density.

To set up the aerator, you need to make sure that the aerator has covered all the corners and sides of the pond so that no mud remains untouched. There are two main designs for placing aerators: parallel and diagonal.

4. Clean the Pond Base Manually

The next tip for managing vannamei shrimp pond is routinely cleaning the pond’s bottom. Manual cleaning or suctioning of waste is good for maintaining optimal pond bottom quality.

So, how often should the bottom of the pond be cleaned? In general, there are no specific rules regarding how often to clean. However, it is recommended to do it once daily so that the waste that settles does not accumulate too much.

5. Periodic Basic Evaluation of Ponds

As the vannamei shrimp farming cycle progresses, it is very important to know the sediment condition at the bottom of the pond to prevent negative impacts. So it is necessary to evaluate periodically by taking sediment samples at certain points. The evaluation parameters include Redox potential, pH, pH2S, and NH4-N sol.

Sampling should be done regularly, at least twice per cycle. Precisely in the middle of the cultivation cycle when the mud begins to form and at the end of the cycle as an evaluation.

However, more frequent evaluations should be carried out in special cases such as mass mortality or slow growth of shrimp.

This is the Difference between Male and Female Shrimp

Farmers need to know the differences between male and female shrimp before hatching. This aims to ensure that the spawned parent shrimp have different sexes with the correct amount ratio.

However, determining the difference between male and female shrimp is sometimes tricky because the two look very similar at first glance. However, some traits can be observed to find the difference.

What are these characteristics? Here we have summarized it for you in this article. So, make sure to read it all the way through.

Also Read: The Organ System and Morphology of Vannamei Shrimp that You Should Know

The Difference between Male and Female Shrimp

The difference between male and female shrimp can be identified from their genitals. In male shrimp, the genitals are in the form of petasma, located on the first swimming leg, which transfers sperm.

Meanwhile, the female shrimp’s genitals are known as thelycum, which is located between the fourth and fifth leg of the road and functions to store sperm.

The female reproductive system uses a pair of ovaries, oviducts, genital openings, and thelycum. While the male reproductive system uses the testes, vasa deferensia, petasma, and masculine appendix.

In addition, the difference between male and female shrimp can also be seen in their body size. The female shrimp parent usually has a larger size than the male parent.

Also Read: Get to Know the Vannamei Shrimp as a Farmers’ Favorite

Criteria for Ideal Shrimp Brood

The ideal female shrimp parent is a parent that has mature eggs. The maturity of the eggs is measured based on the development of the ovaries, which are located on the dorsal side of the shrimp’s body. The ovaries are green the more mature they are, the darker the color.

While the development of perfect petasma determines male shrimp. Usually, this petasma contains a spermatophore.

From the physical condition, the shrimp chosen as broodstock must have at least a minimum weight of 100 grams for females and 80 grams for males. Also, ensure the parents do not have defects or injuries, especially on the reproductive organs, to produce high-quality shrimp seeds.

To determine whether the eggs in the parent have matured, it is usually done in two ways: lifting the female and facing the lower body (ventral) towards the sun. In addition, you can also use a waterproof light beam to observe it.

The Threats of Nitrite in Shrimp Ponds and How to Overcome It

The threat of nitrite in shrimp ponds is an impact on the environment from intensive vannamei shrimp cultivation that all shrimp farmers can face. Therefore, farmers must find out ways to prevent and overcome them immediately.

Vannamei shrimp has long been a species of shrimp cultivated in Indonesia. This is because this type of shrimp is a food that is very popular with people around the world, so its export value continues to increase from year to year.

However, the intensive cultivation of vannamei shrimp can cause various impacts on the environment, one of which is the threat of nitrites. So, how to overcome it? Read more in this article!

Also Read: Get to Know Myo IMNV Disease in Vannamei Shrimp and Its Characteristics

What is Nitrite in Shrimp Ponds?

Nitrite in shrimp ponds is a toxic substance produced from nitrogen which is only partially oxidized. This substance is not found in fresh wastewater but in wastewater that has long been settling and accumulating.

High nitrite levels can result from overfeeding of shrimp, excessive sediment density, poor water circulation, and other factors that upset the balance of the nitrogen cycle.

Nitrite is very toxic to vannamei shrimp. Its presence can cause various adverse effects, including stunted growth and development of shrimp or even death.

Nitrite is not fixed and can turn into ammonia or be oxidized to nitrate at any time. When compared with nitrate, the presence of nitrite in the waters is less. However, the level of toxicity for vannamei shrimp is very high.

The danger of nitrite toxicity in vannamei shrimp ponds is especially evident in the early stages of the cultivation cycle. During this initial stage, nitrite levels can rise rapidly and reach dangerously toxic levels.

The presence of oxygen in shrimp ponds affects the presence of nitrites in shrimp ponds. In general, waters that get an adequate supply of oxygen have lower levels of nitrite concentration when compared to waters that do not get an oxygen supply.

How to Overcome Nitrite Threats in Shrimp Ponds

Even though it has a high level of toxicity, it does not mean that the nitrite threat cannot be overcome. One of the most important steps must be taken is monitoring water quality regularly and keeping other parameters optimal.

This can be done by adjusting the feeding, increasing oxygen circulation, and adjusting the stocking density of vannamei shrimp to prevent overcrowding.

How to deal with the threat of nitrite in shrimp ponds can also be done by adding nitrite-reducing bacteria into the pond. These bacteria can consume nitrites and convert them into less harmful substances, such as nitrogen gas.

Not only that, the presence of bacteria known as Nitrobacter can also help improve water quality along with reduced nitrite levels, making it safe for the growth of cultivated vannamei shrimp.

In addition, it is also essential to keep the pond well-aerated, especially in the early stages of the culture cycle. Adequate aeration helps ensure dissolved oxygen levels remain high, reducing the risk of nitrite toxicity and other water quality problems.
