Understanding Sampling in Shrimp Farming and Its Benefits

During shrimp farming, farmers must constantly monitor the condition and growth of shrimp in the ponds. This is usually done through periodic sampling of the shrimp.

Sampling involves periodically observing the shrimp by taking several specimens from each pond for further examination. This activity is crucial to prevent adverse events in shrimp farming, such as disease outbreaks or suboptimal shrimp growth.

So, what are the objectives and benefits of sampling? Let’s find out in the following article!

What is Shrimp Sampling?

Shrimp sampling is the periodic observation of shrimp by taking several specimens from each pond for further examination. This is done to assess shrimp growth and condition and estimate their feeding requirements.

Sampling is typically conducted periodically from the time the shrimp post-larvae are stocked in the ponds until shortly before harvesting. Shrimp can be collected from different parts of the pond or through netting and then physically examined and tested in the laboratory.

Objectives of Shrimp Sampling

1. Assessing Shrimp Condition

One of the main objectives of sampling is to assess the condition of the shrimp. The observations from sampling serve as a basis for making decisions related to shrimp farming treatments. For instance, if signs of disease are detected, the farmers can promptly take mitigation measures after identifying the issue through sampling.

2. Evaluating Shrimp Uniformity

Shrimp populations are considered good when the size and weight are relatively uniform. To determine this, sampling can be carried out at a specific age of the shrimp, and then the weight and size uniformity can be observed. Knowing the uniformity helps farmers plan the appropriate feed management.

3. Calculating the Survival Rate

Shrimp sampling is also useful for calculating the survival rate (SR) over a specific period. The survival rate is determined by dividing the shrimp biomass by the initial number of post-larvae stocked and then multiplying it by 100%.

4. Calculating Average Body Weight

The average body weight (ABW) is the average weight of shrimp in a population during a specific period. ABW is calculated by dividing the total weight of the sampled shrimp by the number of shrimp collected.

5. Calculating Shrimp Biomass

Biomass refers to the total weight of shrimp in a population during a specific period, expressed in weight units. Shrimp biomass can be estimated by multiplying the survival rate (SR) with the initial population and then multiplying it by the ABW at a specific time.

6. Measuring Shrimp Size

Sampling is also used as a basis for measuring shrimp size. Shrimp size can be determined by counting the number of shrimp per 1 kg. For example, if there are 90 shrimp in 1 kg, it is referred to as “size 90.”

7. Assessing Pond Bottom Conditions

Sampling can also be beneficial for assessing the condition of the pond bottom. This can be done by observing the sediment brought up when casting the net in the pond for sampling. Observations are made to determine if there are shrimp deaths within acceptable limits.

Types of Shrimp Sampling in Shrimp Farming

1. Larvae Sampling

Larvae sampling is conducted to estimate the population size and quality of shrimp post-larvae that will be stocked into the ponds. This is done by randomly collecting a sample of larvae and transferring them to a container for further evaluation. The larvae can be observed under a microscope, undergo stress tests, activity tests, and their numbers are counted.

2. Corner Pond Sampling (Anco)

Corner pond sampling is done with the help of corner nets in each pond. The corner nets are useful for capturing small-sized shrimp. Typically, anco sampling is conducted when the shrimp have reached 25-35 days of age and are not too large.

3. Net Sampling

The last type of sampling in shrimp farming is net sampling. As the name suggests, this sampling method involves using a net to capture shrimp from the pond. Net sampling is usually carried out when the shrimp have reached a relatively larger size (2.5 grams) or at around 30 days after stocking.

Cultivation Preparation Stage

1. Pond Preparation

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

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

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

2. Preparation of Farm and Laboratory Equipment

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

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

3. Preparation of Human Resources

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

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

4. Pond Sterilization

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

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

5. Microorganism Spreading

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

Vannamei Shrimp Cultivation Procedures

1. Selection and Stocking of Seeds

cara budidaya udang vaname — Source: DELOS Documentation

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

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

2. Feeding Management

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

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

3. Do Routine Sampling

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

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

4. Water Quality Management

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

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

5. Vannamei Shrimp Treatment

budidaya udang vaname — Source: DELOS Documentation

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

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

6. Harvest

Capital for Vannamei Shrimp Farming

Vannamei shrimp business is indeed promising, with fantastic profit potential, which has made it increasingly popular among the community. However, on the other hand, the capital required to start vannamei shrimp farming is not insignificant.

The amount of capital for vannamei shrimp farming depends on several factors. For example, the type of technology applied, whether it’s traditional, semi-intensive, intensive, or super-intensive.

The capital for vannamei shrimp farming can be divided into two categories: fixed capital and working capital.

Fixed capital refers to the initial capital invested when starting vannamei shrimp farming. The amount remains constant and is not affected by the fluctuation of operational costs. It includes expenses such as purchasing land (if you don’t already own it), equipment costs, and pond construction.

Working capital for vannamei shrimp farming is the ongoing expenses incurred during the farming process. These costs are fluctuating and depend on the operational needs of the farm. For example, costs for seedlings, fertilizers, feed, supplements, probiotics, and so on.

The amount of working capital can vary depending on your choice of high-quality fertilizers, feed, supplements, and probiotics. This will ultimately result in good harvest quality.

5 Tips to Achieve Profitable Biofloc Vannamei Shrimp Farming

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

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

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

How to Use Biofloc in Vannamei Shrimp Farming?

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

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

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

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

4 Types of Vannamei Shrimp Farms You Have to Know

A shrimp farm is an artificial pond that is used as a habitat for aquaculture activities, one of which is vannamei shrimp. Generally, the pond’s location is near a spring, for example, in a coastal area.

Most people think all vannamei shrimp farms are the same. However, this is not the case. There are several types of farms around us based on management techniques and density levels.

The types of farms include traditional, semi-intensive, intensive, and super-intensive farms. So, what are the characteristics of these farms? Find the full answer in this article!

Also Read: 7 Easy Ways to Cultivate Vanname Shrimp for Beginners

Types of Vannamei Shrimp Farms

1. Traditional Farm

The traditional vannamei shrimp farm is a type of farm that is made quite simply with a relatively low scale of shrimp seed stocking density. Usually, this type of farm does not require a pump and waterwheel. Meanwhile, the change of water depends on the tides.

The stocking density of traditional farm or extensive shrimp farming is <50 shrimp/m².

Due to its relatively low density, traditional shrimp farms have an easier level of maintenance when compared to other types of shrimp farms. Likewise, the risk of shrimp getting diseases is also smaller.

2. Semi-Intensive Farm

The second type of shrimp farm is the semi-intensive farm. This type of farm has a higher stocking density than traditional farms. Therefore, pumps and waterwheels are needed, which are adjusted to the size of the farm area to manage the water flow.

The stocking density of semi-intensive vannamei shrimp ponds is <100 shrimp/m².

As for the feed problem, since the seeds are sown, semi-intensive farms usually directly use artificial feed as the main source of nutrition for vaname shrimp. Along with water quality, this feed is the most important part that must be considered during cultivation.

3. Intensive Farm

An intensive farm is a shrimp farm with a fairly high stocking density of seeds. Usually, this type of farm requires complex design and layout calculations. Starting from the depth of the water, the need for a pump, and the need for a waterwheel, it must follow the needs.

The stocking density of intensive vannamei shrimp ponds is >100 shrimp/m².

When building an intensive farm, waste management also needs to be considered. The reason is that the higher the farms’ density level, the higher the waste generated during cultivation.

4. Super Intensive Farm

The last type of vannamei shrimp farm is the super intensive farm. As the name suggests, this type of farm requires more complex maintenance than other types of ponds. Many considerations must be prepared, ranging from supporting equipment to the impact of cultivation on the environment.

Super-intensive shrimp ponds are the same as intensive ponds, but the size and stocking density is more prominent. Usually, the stocking density of semi-intensive shrimp ponds is >200 shrimp/m².

Starting from the design, layout, need for pumps, number and type of waterwheels, as well as technology and management, must continue to be considered because the impact will be huge on the sustainability of cultivation and the environment where the farm is located.

After knowing the types of farms above, you must already know that we must consider many things before building a shrimp farm. Moreover, for semi-intensive, intensive, and super-intensive farms. Therefore, choosing the right location is very important to do.

The selection of farm locations aims to get the right and appropriate location so that the vannamei shrimp cultivation process can take place properly and the resulting harvest can be optimal.

The ideal farm location must have a good topography level to facilitate farm construction, contain clay-containing soil to hold water and build dams, and have sufficient water supply farms.

Parts of Sustainable and Environmentally Friendly Ponds

Ponds are places where shrimp, fish, and other aquaculture commodities are cultivated. In practice, parts of the pond should be manufactured according to sustainable and environmentally friendly standards.

As a place where shrimp grow, ponds must be designed and given special care to provide ideal conditions for shrimp. This pond consists of various essential parts to function correctly and produce high productivity.

Therefore, below we have summarized the parts of a sustainable and environmentally friendly pond that you can use as a reference.

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

Environmentally Friendly Parts of Ponds

1. Quarantine Pond

The first parts of the pond are quarantine ponds which function as water reservoirs with standard water quality standards. This quarantine pond is used as a water supply when changing new water to rearing ponds or reservoir ponds.

Quarantine ponds are placed before rearing ponds to facilitate water distribution. Optimally, a quarantine pond can accommodate between 30-50% new water, depending on the level of technology applied.

2. Water Distribution Channels

The next part of the pond is the water distribution channel which helps divide water into each rearing pond. Usually, the water distribution channel is placed on a strategic side to facilitate the distribution of water.

For ponds that are small in scale, this pond is usually combined with a quarantine pond to save land.

3. Cultivation Pond

The fry is stocked and raised in a rearing pond until harvest time. Ideally, this pool is located in the middle of the pond. Meanwhile, the area of the pond depends on the cultivation system being run, for example, for an intensive system between 2000-4000 square meters.

Rearing ponds can be square or circular. However, ideally, each corner should be obtuse to facilitate water and waste management at the bottom of the pond.

4. Sludge Pond

As the name suggests, a sludge pond is a storage area for sludge originating from the rearing pond. This pond is located near the water and waste disposal center to facilitate its operation.

Also Read: The Importance of Alkalinity in Shrimp Ponds, Check Your Alkalinity Now!

5. Reservoir Pond

Reservoir ponds or also known as biofilters, are ponds used to filter organisms, pests, and diseases that can harm shrimp. These ponds are usually located after settling patches.

In reservoir ponds, seaweed, mangrove shells, oysters, and mangrove plants are usually found, which function as biofilters to absorb toxic substances such as NH3, CO2, and nitrites in the water.

6. Waste Treatment Pond

The next part of the vannamei shrimp pond is the waste treatment pond, a reservoir for wastewater from the grow-out pond. The water will be chemically and biologically sterilized in this pond before being discharged into the sea.

7. Central Sewer

The central drain is a water disposal system in the middle of a shrimp-rearing pond. This channel is made of cast cement in a round shape to drain water toward the sewer. While in terms of size, it can be adjusted to the needs of each pond.

8. Monik’s Door

The last parts of the pond are monik doors and water discharge gates. This door is made of cast cement and buis concrete, with a control door on the bund’s inner side.

The size of the monic gate depends on the pond area and the existing bund construction. In simple ponds, the drain gate is usually not made of concrete but of wood or PVC.

4 Elements of Vannamei Shrimp Farm Management That Must Be Considered

Lately, vannamei shrimp cultivation is growing rapidly and is in great demand because of its advantages compared to other types of shrimp. However, cultivating without good farm management could even be a loss.

Various benefits can also be obtained if we apply good farm management. Starting from feed efficiency, preventing shrimp from disease attacks, and maintaining environmental sustainability, so that the productivity of the resulting pond can be maximized.

Then what should be considered in good shrimp farm management? Read until the end of this article to find the answer!

Also Read: 10 Types of Shrimp for Aquaculture and Aquascape

1. Water Quality Management

farm management yang baik — Source: DELOS Documentation

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

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

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

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

2. Vannamei Shrimp Feed Management

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

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

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

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

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

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

4. Aquaculture Waste Management

Vannamei Shrimp Farm Management — Source: DELOS Documentation

As we know, aquaculture, including vannamei shrimp, produces organic waste that can pollute the surrounding waters. Therefore farmers need to have aquaculture waste management.

Farm waste is mostly in the form of easily degraded organic waste. These wastes come from feed residues, fermented materials, shrimp manure, and other organisms in the pond.

The management of vannamei shrimp culture waste can be carried out by being disposed of or cleaned through a siphon channel, decomposed with probiotics, or oxidized with oxygen.

Cultivating Vannamei Shrimp with Biofloc System

Vannamei shrimp biofloc has become a popular cultivation system lately. Biofloc technology was first applied by Dr. Yoram Avnimelech in Israel and experienced immediate success. Finally, the biofloc system was also implemented in shrimp ponds in Indonesia.

In a way, the vannamei shrimp aquaculture biofloc system is a form of innovation to address feed problems experienced by farmers. The reason is by implementing the biofloc system, the shrimp’s natural feed supply becomes more abundant.

Farmers who want to apply the biofloc system to vannamei shrimp cultivation must practice it correctly because a bit of wrong in practice can be fatal.

Therefore, here we have summarized the method of cultivating vannamei shrimp using the biofloc system, which you can use as a reference.

What is the Biofloc System?

Biofloc is a bunch of microorganisms such as bacteria, protozoa, fungi, plankton, and organic matter from undecomposed waste.

While the biofloc system attempts to utilize leftover shrimp feed waste to become microbial feed, the rest of the feed waste will be degraded, and the microbes in it will develop and multiply until, finally, the floc is produced.

Floc can be a good source of protein for shrimp. This is because decomposed organic compounds contain carbon (C), hydrogen (H), oxygen (O2), nitrogen (N), and phosphorus (P) compounds.

With the vannamei shrimp biofloc, the farmers can reduce operational costs, which are usually used to purchase feed. This is because the biofloc system can lessen the Feed Conversion Ratio (FCR) while minimizing disease outbreaks.

However, keep in mind that the biofloc system does not affect overall farm productivity because the microorganisms formed only serve as additional feed.

Vannamei shrimp cultivation using the biofloc system can be applied to start from intensive to super-intensive system ponds that have high stocking densities. However, firstly the pond must have a high level of aeration with the appropriate wheel position. The pond must be covered with concrete or high-density polyethylene (HDPE), as well as additional pellets and molasses.

In addition, farmers must always carry out biofloc control during vannamei shrimp cultivation.

How to Cultivate Vannamei Shrimp with the Biofloc System

Until now, many Indonesian shrimp farmers are interested and have applied the biofloc system. However, few also experience failure due to a lack of understanding of this technology.

Therefore, here is a method of cultivating vannamei shrimp with the biofloc system that you can practice.

1. Prepare the Pond very Well

The vannamei shrimp biofloc system can only be applied in some ponds. Particular standards must be met so that the cultivation of vannamei shrimp goes well and does not suffer losses.

The standards for pond ponds that must be met include pond sizes adapted to the cultivation system, ponds that do not leak and have been coated with thick HDPE concrete or plastic, sound aeration systems, and pond heights ranging from 0.8-3 meters.

2. Choose the Right Probiotic Bacteria

The vannamei shrimp biofloc system relies on probiotic bacteria for each pond. Bacillus subtilis is a type of probiotic bacteria that can be selected because this bacteria can decompose nitrogen elements properly and can maintain water quality.

Another type of bacteria that can be used is Bacillus cereus which can form bacterial flocs while controlling the growth of green algae.

3. Make Biofloc Starter

After selecting probiotic bacteria, the next step is to make a biofloc starter. This stage is the same as fermentation to increase the number of bacteria in the pond, which functions as a quality guard for Biopolymer (PHA), which helps the process to suppress harmful pathogens.

4. Spread High-Quality Shrimp Fry

When the ponds with biofloc technology are ready, farmers can start spreading the shrimp fry into the pond. However, to get the best quality cultivation results, choose high-quality and certified fry.

5. Perform Proper Feed Management

When the flock has not been formed, farmers can provide feed like ordinary vannamei shrimp cultivation. For example, feeding in pellets twice a day according to needs.

Then when the flock has begun to form, you can start reducing feeding because this is where the role of floc is as a natural food source for shrimp. With this flock, farmers can reduce FCR and save farm operational costs.

6. Ensure Dissolved Oxygen Supply (DO) is fulfilled

When choosing to use biofloc technology, farmers must ensure a continuous supply of dissolved oxygen (DO). This is because ponds that lack an oxygen supply can cause the shrimp in them to die.

To ensure that the supply of dissolved oxygen (DO) is met, farmers can use aerators or waterwheels as additional tools to supply extra oxygen. In addition, make sure the number of aerators or water wheels per the pond’s area.

In biofloc vannamei shrimp farming, the aerator or waterwheel not only acts as an oxygen supply but also keeps the biofloc suspended. However, it should be noted that high levels of suspended biofloc biomass can cause a decrease in pond water quality and ultimately result in crop failure.

Advantages and Disadvantages of the Biofloc System

The biofloc system is only sometimes superior to the vannamei shrimp farming system. There are positive and negative sides to this cultivation system. Following are the advantages of biofloc technology:

Very high biosecurity
Production capacity and carrying capacity are usually 5-10% higher
Shrimp grow bigger with lower FCR
15-20% lower production costs

Meanwhile, the shortcomings of the biofloc system include the following:

Requires a high energy supply for the aerator
Failure of energy supply for more than 1 hour can be fatal and critical
The biofloc pond must be lined
Technicians must receive specific knowledge and training to understand this technology fully.

Vannamei Shrimp Cultivation Prospect

The increasing global market demand for vannamei shrimp has made many people start looking at this business. Both include small-scale ponds, such as traditional ponds, and large-scale ponds, such as intensive and super-intensive ponds.

Vannamei shrimp has a fast growth rate, shorter cultivation time, and better environmental resistance when compared to other types of shrimp. In addition, vannamei shrimp are also relatively more resistant to disease.

Since it was officially introduced in Indonesia in 2001, vannamei shrimp have immediately become the prima donna of farmers. Moreover, due to disease, tiger prawn cultivation continued to decline at that time.

Indonesia has long been one of the largest shrimp exporters in the world. In 2021, Indonesia was ranked 4th after India, Ecuador, and Vietnam.

However, considering that Indonesia is the largest maritime country in the world, the potential stored in vannamei shrimp production still has relatively large prospects. If optimized, Indonesia can become a leader in shrimp producers and exporters.

Until now, of the total ponds in Indonesia, 75% of them can only contribute 10% of the total quantity of exports. The lack of full maintenance and management of ponds causes this.

Therefore, until now, the prospect of vannamei shrimp farming is still quite tempting. Given the broad market potential, environmental conditions and human resources support Indonesia.
