The Efficiency of Vannamei Shrimp FCR for Successful Cultivation

Feed management is one of the determinants of the success of vannamei shrimp farming. To know about this efficiency, we must first calculate the vannamei shrimp FCR.

FCR or feed conversion ratio, is the result of calculating the effectiveness and efficiency of the stocked feed. Through FCR calculations, you can find out whether the feed given is actually eaten by the shrimp or is left over and becomes a waste.

In Indonesian, FCR is also known as rasio konversi pakan, which can indicate the level of efficiency of feed management in every cultivation that is carried out. The smaller the FCR number, the more efficient the feed management is.

Therefore, let’s learn what FCR is and how to calculate it below.

What is Vannamei Shrimp FCR?

Feed conversion ratio or FCR is the calculation of the total weight of artificial feed divided by the cultivation’s total weight (biomass). In vannamei shrimp, the ideal FCR value ranges from 1.1-1.2. The smaller the FCR value obtained, the greater the profit obtained by the farmers.

Not only vannamei shrimp but FCR also applies to other aquaculture commodities, such as catfish, salmon, etc. In contrast, the high or low FCR is determined by the type of feed, species, animal size, feeding practices, water conditions, and the run culture system.

The Importance of FCR in Vannamei Shrimp Cultivation

The feed conversion ratio (FCR) is an essential metric in vannamei shrimp farming because it can provide information about the feed’s efficiency during cultivation.

The low number of vannamei shrimp FCR indicates that the feed given to vannamei shrimp is well absorbed and makes cultivation more profitable from an economic and sustainability point of view.

Conversely, a high FCR indicates that the feed is inefficient and can lead to increased costs and lower profits for the farmer. In addition, a high FCR number also harms the environment, especially in terms of water pollution.

How to Calculate Vannamei Shrimp FCR

To calculate FCR in vannamei shrimp farming, you must first determine the amount of feed given to the shrimp and then measure the weight gain of the shrimp over a certain period.

FCR is then calculated by dividing the feed given to the shrimp by the increase in shrimp biomass. The Feed Conversion Ratio (FCR) formula is as follows:

For example, the shrimp biomass that you cultivate is 1 ton (1000 kg). While the amount of feed that has been given is 1.2 tons (1200 kg). Then the FCR of vannamei shrimp is 1200: 1000 = 1.2.

Tips for Vannamei Shrimp FCR Efficiency

Adjusting feed distribution is crucial to maintain an optimal FCR (Feed Conversion Ratio). Several aspects need to be considered to achieve efficient FCR, including:

1. Shrimp Needs and Age

Feeding Vannamei shrimp must align with their needs and age. For instance, for shrimp younger than 15 days, it is recommended to provide powdered feed for easier digestion. Meanwhile, during the 16-45 day DOC (Day of Culture) period, crumbled feed is more suitable.

Fundamentally, the types of feed for Vannamei shrimp vary, depending on nutritional requirements, feed size, and shrimp age.

2. Feeding Methods

Feeding can be done manually by direct spreading or using an autofeeder. In choosing a feeding method, consider the feed quantity, schedule, and ensure even distribution throughout the pond. Accumulation of excess feed can affect water quality.

3. Feeding Frequency

Apart from considering shrimp needs and age, the frequency of feeding plays a crucial role. The time interval between feedings should allow shrimp enough time for digestion, ideally 48-90 minutes. The digestion process itself takes around 4-6 hours before becoming waste.

For shrimp younger than 15 days, feeding three times a day is sufficient. For shrimp aged 16-30 days, feed four times a day in accordance with their feeding capacity during that phase.

When shrimp surpass this age, feeding can be increased to five times a day. This is based on the consideration that the dissolved oxygen conditions in the pond are still optimal.

Important Steps to Maintain Shrimp Quality During Harvest

Shrimp is a crucial export commodity for many countries, including Indonesia. For shrimp farmers, maintaining the quality of shrimp during harvest is crucial to achieve maximum yields and meet market demands.

The proper harvesting process of vannamei shrimp ensures that they remain fresh, of high quality, and free from contamination by other organisms. In this article, we will discuss the important steps that need to be considered during harvest to keep the shrimp fresh until they reach consumers’ hands. Read more below!

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

1. Determining the Right Harvest Time

Selecting the appropriate harvest time is essential to ensure optimal shrimp quality. Shrimp should be harvested when they have reached the desired market size. Allowing shrimp to stay in the pond for too long can lead to overgrowth and a decrease in shrimp meat quality.

2. Pond and Equipment Preparation

Before harvesting, make sure the shrimp ponds are clean from various debris and uneaten feed. The pond water should be in good condition and free from substances that can harm shrimp quality.

Also, ensure that harvesting equipment such as nets and storage containers are thoroughly cleaned and sterilized before use. Contamination from dirty shrimp equipment can lead to decay and a decline in shrimp quality.

3. Use of Anesthesia

Using anesthesia before harvesting can help reduce stress on shrimp and prevent damage to the shrimp’s quality. Anesthesia keeps the shrimp calm during the capture, transportation, and further handling processes. Some shrimp farmers use natural materials like coconut leaf extract or clove extract as anesthesia, which is safe for shrimp and does not leave harmful residues.

4. Proper Handling

During harvesting, farmers should be careful not to damage or cause injuries to the shrimp. Injured or damaged shrimp can become a source of infection for other shrimp.

Avoid stepping on shrimp or stacking them excessively. Additionally, do not expose shrimp to air for too long, as they need moisture to remain fresh.

5. Rapid Cooling

After harvesting, shrimp should be immediately cooled to slow down the decomposition process and maintain the freshness of the shrimp meat. Shrimp are perishable organisms, so proper storage temperatures are essential. Use ice or other cooling methods to keep shrimp at a low temperature during transportation from the pond to processing or market areas.

6. Sorting and Grading

Sorting and grading are other essential steps in maintaining shrimp quality. Shrimp should be sorted based on size and type. Larger shrimp usually command higher prices, while shrimp with good quality should be separated from defective ones. Grading ensures that the shrimp being sold meets consumers’ expected standards.

7. Proper Preservation Methods

If shrimp will not be sold or processed immediately, farmers should use appropriate preservation methods to maintain their quality. Common preservation methods include salting, drying, or applying low temperatures. The choice of preservation method should be based on market needs and the type of shrimp being harvested.

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.

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.

12 Equipments for Vannamei Shrimp Ponds that Must Be Prepared

Vannamei shrimp pond equipment is the main thing that must be prepared before carrying out cultivation. This is because each pond must have its equipment and may be used differently.

Both small-scale and large-scale vannamei shrimp farming requires complete pond equipment, from intensive to semi-intensive ponds. Starting from aerators, and laboratory equipment, to equipment that must be in every pond.

So, here is the vannamei shrimp pond equipment that you have to prepare before cultivating:

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

1. Aerators

The first vannamei shrimp pond equipment is an aerator or water wheel. The aerator plays a role in maintaining dissolved oxygen in the water and controlling the dirt and sludge in each pond.

Several types of aerators include waterwheels with paddle wheels, spiral, pump, vertical, and jet aerators. Meanwhile, the type selection depends on the type of cultivation being carried out.

2. Geomembrane (Plastic Coating)

Geomembrane is a plastic layer used as the bottom of the pond so that pond water does not mix with the soil. This layer maintains air quality to remain clean and not easily polluted.

Usually, the type of geomembrane used is mulch plastic or HDPE with a minimum thickness of 0.50 microns.

3. DO Meters

The DO Meter or Dissolved Oxygen Meter is vannamei shrimp pond equipment that measures dissolved oxygen in pond ponds. During cultivation, farmers must ensure that the supply of dissolved oxygen is at least > 4 ppm so that the shrimp can grow optimally.

4. Refractometer

A refractometer is a tool used to measure salinity in vannamei shrimp ponds. This vannamei shrimp pond equipment is quite important when the pond preparation stage is carried out, namely to measure the similarity of salinity between pond water and water in fry bags.

The optimal salinity level in vannamei shrimp pond water is 15-25 ppt.

5. pH meter

During cultivation, farmers must ensure that the pH of the water is always in optimal conditions. Therefore, a pH meter is needed to measure the acidity level of each pond.

How to use this vannamei shrimp pond equipment is first to take a sample of pond water, and then the pH meter will automatically show the pH number of the water. The optimal water pH for vannamei shrimp is 7.5-8.5.

6. Water Pump

Like water pumps in general, the water pump in vannamei shrimp ponds functions to drain water into the pond during pond preparation. In addition, this water pump also functions to ship the manure from the pond.

7. Shrimp Nets

Nets or nets are vannamei shrimp pond equipment needed when the harvest arrives. Not only the whole harvest, shrimp nets are also needed during partial harvesting and daily sampling.

8. Anco

Anco is vannamei shrimp pond equipment that must be in every pond. Usually, anco is placed in the corners of certain ponds with a calmer current. Each pond has one to four anco, which are adjusted to the pond area.

9. Siphon Hose

Siphon hoses in vannamei shrimp ponds are useful for sucking up the sludge at the bottom of the pond and draining it into the sewer. To carry out its function, this hose utilizes the force of gravity and water pressure.

In addition, siphon hoses can be used to detect death or if molting occurs in vannamei shrimp.

10. Secchi Disk

The Secchi Disk is vannamei shrimp pond equipment used to measure the turbidity level of water. Turbid pond water can cause oxygen holding capacity to be low, fish visibility to be reduced, and appetite to be disturbed. Of course, this can impact fish growth which becomes less than optimal.

As the name suggests, Secchi disks are circular, resembling discs whose surface is patterned in black and white. How to use it is quite easy, namely by tying it with a rope and putting it in the water. When the pattern on the secchi disk is no longer visible, the water pond’s brightness limit is at that depth.

11. Lighting Lamp

Lighting is one of the pieces of equipment that must exist in a shrimp pond. This lamp is one of the safety equipment that must be available to make it easier for farmers to monitor the condition of shrimp at night.

Usually, the type of lamp used has a wattage that is not too high, and the light needs to be more brightly. This is because shrimp are quite sensitive to light, which can cause stress to the shrimp.

12. AquaHero

The last name shrimp pond equipment is AquaHero. AquaHero is an application that you can operate via a gadget to record and monitor the growth of your shrimp during cultivation.

With AquaHero, you can also record daily water quality, get recommendations for action based on scientific analysis, and get an estimated Break Event Point (BEP) for cultivation.

How to Reduce Vannamei Shrimp FCR for More Profitable Cultivation

In vannamei shrimp farming, feed management is essential because feed costs around 40-50% of the total costs incurred during cultivation. Therefore, farmers must know how to reduce the FCR (feed conversion ratio) to manage feed costs.

Poor feed management can cause several problems. One that is often encountered is overfeeding. This causes high FCR and production costs during cultivation.

However, before knowing how to reduce the FCR, farmers must first understand what causes the FCR in the vannamei shrimp culture to be high. Come on, see the following discussion to find out.

Also Read: The Efficiency of Vannamei Shrimp FCR for Successful Cultivation

Causes of High FCR

Limsuwan (2010) states five mistakes generally occur in vannamei shrimp feed management practices. These errors lead to high FCR numbers.

1. High Pond Water Temperature

Water temperatures higher than optimal conditions can cause the shrimp’s metabolic system to be disrupted. This causes a decrease in shrimp appetite so that the feed is unused. The accumulation of leftover feed and feces at the bottom of the pond can reduce the quality of pond water, impacting the shrimp’s health. In addition, the growth of the shrimp will also be slow because the feed given needs to be eaten completely.

2. Overfeeding

Overfeeding is a common problem when farmers determine the amount of feed given based on the amount of feed remaining in the anco. On the other hand, farmers must provide feed based on the stocking density of shrimp.

Farmers must know how many fries are stocked in each pond and consistently monitor the survival rate (SR) to determine how many shrimp are left in the pond to calculate the amount of feed to be given.

3. Frequency of Excessive Feeding

Usually, the feeding of vannamei shrimp is 3 to 5 times daily for 4.5 hours.

However, few farmers use a different feeding system, for example, four times a day for only 3 hours. With this feeding frequency, more feed will be left, and the FCR will be high.

4. The Water Flow is Too Fast

In intensive system vannamei shrimp farming, shrimp cultivated with high stocking densities require several ‘wheels’ to maintain optimal DO (dissolved oxygen). However, if the waterwheel current is too fast, the feed will settle in the middle of the pond so that the shrimp will not eat and waste it.

The way to prevent this problem is to turn off some of the waterwheels at the time of feeding so that the water currents do not carry the feed to the pond’s center. However, all the pinwheels should not be turned off simultaneously, especially if the prawns have reached their adult size. This is to avoid the shrimp’s lack of oxygen.

5. Lack of Waterwheels

A sufficient number of wheels in a pond can prevent sediment from accumulating at the bottom of the pond. This causes the oxygen levels in the pond to decrease and fall below the optimal level, which triggers a decrease in appetite and growth of vannamei shrimp so that the FCR becomes high.

In addition, oxygen levels that are not optimal can also make aerobic bacteria not get enough oxygen to break down the sludge and sediment that has accumulated in the middle of the pond, so that anaerobic bacteria will take over the decomposition process with by-products that are harmful to shrimp, such as ammonia, nitrite, and hydrogen sulfide (H2S).

The way to prevent the problem of lack of pinwheels is to reduce the number of shrimp stocked in the pond so that there will be enough oxygen and the pond bottom will remain clean during the rearing period.

How to Reduce Vannamei Shrimp FCR

1. Make Sure the Water Quality is Always Optimal

Maintaining water quality parameters in maintenance to ensure optimal growth and FCR of vannamei shrimp is important for the growth and health of vannamei shrimp. Shrimp are very sensitive to environmental changes, and optimal water quality is expected to produce a good FCR value.

2. Optimize Stocking Density

Excessive vannamei shrimp stocking densities can result in high FCR because shrimp compete for food and space. Some tips for optimizing the feed conversion ratio (FCR) can be done by giving feed periodically throughout the day, avoiding overfeeding, make sure the feeding is done evenly.

3. Do Regular and Proper Feeding

Shrimp need proper feed intake to grow and achieve optimal feed conversion ratio (FCR). Therefore, farmers must provide feed regularly throughout the day with the appropriate dose based on the age and body size of the shrimp.

4. Adjust the Feeding Frequency

Vaname shrimp must be fed with sufficient frequency to meet their nutritional needs. However, the frequency of this feeding should not be too frequent which can cause the feed not to run out and be wasted.

Excessive feeding can lead to higher FCR due to increased uneaten feed residue. This leftover feed can also damage water quality and reduce growth rates.
