Feed in vannamei shrimp cultivation is an essential component for shrimp growth. In addition, the feed also affects the amount of capital issued by farmers. Not surprisingly, everyone wants to implement good vannamei shrimp feed management, so they don’t lose money.

In addition to feeding management, feed quality also determines the quality of the vannamei shrimp produced at harvest. Feed must contain sufficient nutrition, starting from protein, carbohydrates, vitamins, and minerals.

So, for the vannamei shrimp farming that you are doing to be a big success and of high quality, here are feed management tips that you should pay attention to.

Why Should Shrimp Farmers Know Effective Feeding Practices?

During shrimp cultivation, feed is the component that consumes the most capital, accounting for around 50-70% of the total capital invested. Therefore, it is important for farmers to practice effective feeding to ensure optimal shrimp growth while also minimizing the budget spent.

Good and effective feeding is tailored to the age and weight of the shrimp to maximize their growth. If farmers make mistakes in this regard, the risk of losses can loom large.

Furthermore, uneaten feed can cause problems in the pond environment, such as the accumulation of organic waste. The side effects of overfeeding include feed being left uneaten by the shrimp and eventually settling at the bottom of the pond. This leftover feed can generate ammonia, nitrite, and nitrate, which are harmful to shrimp survival.

Food and Eating Habits of Shrimp

Shrimp is an omnivore or all-eating group. Shrimp usually eat phytoplankton, copepods, larvae, and lichens in the wild. Meanwhile, if raised in ponds, farmers usually provide artificial feed as the main feed.

Artificial feed is deliberately prepared for vannamei shrimp, usually in the form of pellets or crumbles. In this artificial feed, shrimp need essential nutrients to grow and develop properly.

The nutrients needed by vannamei shrimp include protein, fat, vitamins, essential amino acids, carbohydrates, and minerals. These nutrients play an important role in the growth and development of vannamei shrimp.

The artificial feed has special criteria, such as having nutrients according to the needs of the shrimp, the feed being easy to digest and the diameter matching the opening of the shrimp’s mouth, and the shrimp’s body quickly absorbing the nutritional content.

Profitable Vannamei Shrimp Feed Management Tips

Feeding for vannamei shrimp cultivation is an important thing that every farmer must consider. Items that need to be considered include the type, frequency, size, and total feed requirements during cultivation.

Efficient use of feed during vannamei shrimp cultivation is one of the factors for successful cultivation. This is because feed is the most expensive factor of production. For that, here are vannamei shrimp feed management tips that you can use as a reference.

1. Determine the Amount of Feed Based on the Age (DOC) of Shrimp

Determination of the amount of feed given to vannamei shrimp must be based on the age of the shrimp. For example, for shrimp with DOC under 30 days, feeding can be done by blind feeding because feed requirements cannot be calculated accurately.

Meanwhile, when the DOC of shrimp is more than 30 days, farmers must carefully calculate the amount of feed given according to the needs of the shrimp. Usually, the calculation is based on the survival rate, the average body weight of the shrimp, and the feeding rate.

2. Frequency of Feeding

The frequency of feeding is the second thing that must be considered when managing vannamei shrimp feed. Feed consumed by shrimp normally will be processed for 3-4 hours after consumption. This can be a benchmark that you can use in determining the frequency of feeding each day.

In addition, the condition of dissolved oxygen (DO) in the pond can also be another consideration. This is because DO affects the vannamei shrimp metabolic process. Therefore, ensure the feeding is done when the pond water DO is in good condition.

3. Make Sure the Method of Feeding is Done Correctly

Artificial feeding for vannamei shrimp is usually carried out from when the fry begins to be stocked until the harvest. However, the types of feed given are differentiated based on the age (DOC) of the shrimp. In addition, the amount of feed must also be considered carefully so that the shrimp have a sufficient feed.

Feeding can be done in two ways: direct distribution around the pond area and feeding placed in the feed anco.

While still in the early stages of cultivation, feeding in the form of crumble must be mixed with water so that the feeding is evenly distributed, sinks quickly, and does not scatter in the wind. Furthermore, feeding can be spread directly around the pond or using anco.

Tips and Procedures for Shrimp Health Checking

Vannamei shrimp are known to be superior to tiger prawns in terms of resistance to pathogen attacks. However, there have been changes that render vannamei shrimp vulnerable to pathogen attacks as well. Therefore, farmers must know the correct procedures for checking shrimp health to prevent outbreaks.

Pathogen attacks on shrimp can affect aquaculture yields. Bacterial and viral pathogens can spread rapidly, causing massive deaths and resulting in significant economic losses.

Anticipation efforts against these pathogen attacks can be carried out through periodic shrimp health checking, namely by monitoring virus and bacterial tests using PCR. Here are the complete tips!

Tips and Procedures for Shrimp Health Checking

1. Routine Sampling

Sampling involves periodically observing the condition of shrimp by taking several shrimp from each pond for further examination. This sampling activity is important as a preventive measure against disease outbreaks. 

Through sampling, farmers can quickly identify any shrimp health anomalies before diseases spread widely.

2. Checking the Hepatopancreas and Intestines of Shrimp

After taking shrimp from the pond for sampling, farmers should check the hepatopancreas and intestines of the shrimp. These two organs can provide further insights into shrimp health and diagnose diseases as early as possible. 

To check the hepatopancreas and intestines of shrimp, you can follow these steps:

  1. Weigh the sampled shrimp.
  2. Spray the shrimp’s body with alcohol and transfer it to a petri dish containing physiological saline or sterile aquadest.
  3. Dissect the shrimp by opening the cephalothorax or shrimp head and dissecting the dorsal or upper abdomen with sterile tweezers. Then separate the hepatopancreas and intestines of the shrimp.
  4. Take a small portion from the lower side of the hepatopancreas with tweezers.
  5. Place the hepatopancreas and shrimp intestines samples on two different object glasses, then add a little water before covering them with another object glass.
  6. Observe both samples under a microscope at a magnification of 40-100x. Record and analyze the results carefully.

3. Shrimp Health Testing by PCR

Bacteria and viruses are the two main causes of shrimp disease outbreaks that harm aquaculture. To determine bacterial or viral attacks as the cause of shrimp disease outbreaks, farmers can perform PCR tests, which provide accurate results. 

It is advisable to perform PCR tests regularly on certain post-larval shrimp to detect pathogen attacks as early as possible.

4. Monitor Mortality Rates During Cultivation

During the cultivation of vannamei shrimp, shrimp deaths often occur. However, you must know the exact mortality rate to minimize the difference between the actual population and the estimated population with mortality corrections. 

Mortality corrections are divided into two types: daily mortality, which is performed every day, and disease outbreak mortality, which is performed during disease outbreaks. Deviations during mortality corrections are usually caused by cannibalism, shrimp carcasses left in ponds, inadequate centralization, and so on.

How Many Times Can Shrimp be Harvested in a Year?

Shrimp is one of the important fisheries commodities for Indonesia and other countries around the world. Typically, in one year, a shrimp pond can be harvested several times depending on various factors. These factors include the type of harvest, the cultivation method employed, environmental conditions, and cultivation management. Therefore, there is no exact number for how many times shrimp can be harvested in a year.

Here are some factors that influence how many times shrimp can be harvested in a year. Read more in this article!

Also Read: This Is How to Make Shrimp Paste at Home

Factors Affecting Shrimp Harvest

1. Shrimp Cultivation Methods

There are several common shrimp cultivation methods, including traditional (extensive) shrimp farming, semi-intensive, intensive, and super-intensive. Each cultivation method is supported by technology that allows for harvesting several times a year.

In traditional shrimp farming, which covers large areas with low shrimp populations, harvesting is generally done once or twice a year. This depends on the natural growth cycle of shrimp and environmental conditions.

Semi-intensive shrimp farming involves better technology than traditional farming, where shrimp are provided with additional feed and environmental conditions are more controlled. With this type of cultivation, harvesting can be done three to four times a year.

Next, in intensive farming systems involving more advanced and controlled pond technology and management, shrimp can be harvested four to six times a year. This includes partial harvesting as well.

Lastly, super-intensive shrimp farming, which utilizes high technology and limited space to cultivate large quantities of shrimp, can be harvested more frequently, typically every two to three months. This also includes partial harvesting when shrimp reach a certain age.

2. Cultivation Management

Good pond management practices are crucial in shrimp farming as they directly impact productivity and the health of the shrimp population. Proper feeding is one of the key aspects of this management, as adequate nutrition is essential for shrimp growth and development. Additionally, maintaining water quality is crucial because shrimp are highly susceptible to extreme changes in water quality. Clean water with appropriate parameters such as temperature, salinity, and dissolved oxygen can enhance the environmental conditions for optimal shrimp growth. Disease prevention is also an integral part of pond management, where efforts such as shrimp health monitoring, the use of probiotics, and sanitation practices can help reduce the risk of diseases and shrimp mortality.

Good management not only affects shrimp health but also impacts harvesting frequency. By reducing the risk of shrimp diseases and mortality, farmers can ensure that the shrimp population remains healthy and productive, allowing for more frequent harvests. Furthermore, effective management also allows for the optimization of pond resources and feed utilization, which in turn can improve cultivation efficiency and produce shrimp at lower production costs.

3. Market Demand

Market demand levels are also important factors influencing farmers’ decisions in determining their shrimp harvesting schedules. When market demand increases and prices remain stable, farmers tend to respond by accelerating their harvesting schedules to meet the high demand.

This is a common strategy to optimize the profitability of shrimp farming businesses, where farmers take advantage of favorable market opportunities by increasing harvest frequencies to meet consumer demand. By carefully considering market dynamics, farmers can schedule harvests appropriately to optimize income and ensure the sustainability of their businesses.

How to Make Shrimp Farming More Resilient to Climate Change

Creating shrimp farming that is more resilient to climate change is crucial to maintaining high productivity. Especially since many shrimp ponds rely heavily on environmental conditions, particularly the availability of clean water at stable temperatures.

Fluctuating climates significantly impact shrimp farming, especially regarding water temperature, changes in rainfall patterns, and the potential for storms. While the effects of climate change are highly unpredictable, adaptation measures must be implemented by farmers to ensure their shrimp farming becomes more resilient to these changes.

Adapted from the writings of Kyra Hoevenaars and Jonah van Beijnen, here are some tips you can follow to make shrimp farming more resilient to climate.

Also Read: HACCP Certification: Procedures, Requirements, and How to Obtain It

Tips For Making Shrimp Farming More Resilient to Climate Change

1. Implement Good Farming Management

Implementing good shrimp farming management is the first step in addressing climate change, especially concerning the location of shrimp farming, ensuring appropriate stocking densities, and ensuring the biosecurity of your shrimp ponds.

Vulnerability to diseases is likely to increase with climate change because shrimp immune systems can be compromised when experiencing stress due to significant environmental changes in relatively short periods. By implementing good shrimp farming management, vulnerability to climate change-induced diseases can be prevented and mitigated.

2. Conduct Risk-Based Analysis

If you’ve just opened a new shrimp farming area, risk-based analysis should be conducted regarding climate change and other extreme weather events. This can also be applied to existing shrimp ponds. Analysis can be performed by examining climate change risks, potential impacts, and risk mitigation capacities.

If after conducting risk-based analysis problems cannot be addressed, relocating ponds to safer areas should be considered. Typically, this issue is faced by areas prone to drought and flooding.

3. Product Diversification

Product diversification is a common strategy used to reduce risks of losses due to climate change. This allows production to continue if one type of farming fails.

Diversification only works if different species are not subject to the same risks, such as specific disease outbreaks. Economically, diversification also makes farmers’ income sources more varied, stabilizing production and potentially increasing resource efficiency.

Additionally, market diversification between local, national, and international options is also important.

4. Utilize Early Warning Systems

Farmers should be familiar with climate change information and climate variations from reliable sources. Obtaining timely information or even earlier can allow farmers to respond more quickly to potential risks.

For example, understanding weather forecasts from the Meteorology, Climatology, and Geophysics Agency (BMKG). Through this, you can prepare for upcoming extreme weather, so you know what treatments your ponds will need next.

5. Improve Pond Infrastructure

To make shrimp farming more resilient to climate change, you need to improve your shrimp pond infrastructure. For example, by building higher and stronger embankments to protect against floods or creating deeper ponds in preparation for the dry season.

During the rainy season, it is important to ensure that your ponds can drain water out properly. For this, it is important to ensure that pipes and channels for water inflow and outflow, as well as drainage, work properly.

Moreover, ensure that the water channels are wide enough to accommodate extra water during heavy rains and floods. While during the dry season, these channels can be useful for ensuring the supply of water from the sea or rivers to the ponds.

6. Collaborate with Others

Most climate adaptation measures cannot be implemented by individuals alone. Therefore, farmers need to collaborate to achieve a common goal of productive and climate-resilient farming.

Through this organization, the exchange of knowledge and experiences can become stronger. Furthermore, access to information and existing resources. Taking collective responsibility in adapting to climate change is an important step in building farming that is more resilient to climate change.

Source: DELOS Documentation

If you have been in the aquaculture industry for a long time, especially shrimp farming, you might know there are many unique terms which generally abbreviated. Starting from ABW, MBW, FCR, SR, and many more.

The term MBW comes from the mean body weight, which means the average weight. In shrimp farming, MBW is the average weight of shrimp per head obtained from routine sampling during cultivation.

The purpose of doing this MBW calculation is to determine the condition and growth of shrimp. In addition, if certain diseases attack the shrimp, it can also be known from the sampling carried out regularly by looking at the anomalies of its growth.

In addition, if there is an anomaly in the growth of shrimp or even if the shrimp is infected with diseases, it can also be identified through abnormal MBW conditions as an early detection before further lab research is carried out.

Also Read: Types of Vannamei Shrimp Feeds to Make Your Shrimp Grow Faster

How to Calculate MBW of Shrimp?

How to calculate the MBW of shrimp is quite easy to do; the first step is to take a random sampling of shrimp at several anchor points in the same pond map. The shrimp that were successfully taken were then weighed and counted.

After calculating each weight and number of shrimp in the sampling, you can use a special formula, namely by dividing the total weight of the shrimp by the total number of shrimp weighed.

Simply put, the shrimp MBW formula is as follows:

Tips for Choosing and Determining the Number of Shrimp Pond Aerators

Shrimp pond aerators are one of the essential equipment in intensive and super-intensive aquaculture. These aerators, also known as aerators, are useful for maintaining dissolved oxygen (DO) levels within the optimal range.

Additionally, aerators serve several other functions, such as stratifying DO concentrations in ponds, regulating sediment deposition, stabilizing water currents in ponds, maximizing feed distribution areas, and minimizing dead spots in ponds.

The presence of shrimp pond aerators is crucial, so you need to ensure you have chosen good quality aerators and installed them in the right quantity in your vannamei shrimp ponds. Find out more tips in this article!

Also Read:  How to Easily Calculate Vannamei Shrimp Size

Tips for Choosing Shrimp Pond Aerators

1. Ensure the Quality of Shrimp Pond Aerators

Currently, many domestic and international aerator factories offer high-quality aerators at affordable prices. Aquaculturists can conduct small research to compare the quality and prices of each aerator factory available. By conducting this research, aquaculturists can obtain the necessary information to make the right decision in choosing aerators that suit their needs.

2. Pay Attention to Aerator Power

The oxygen requirements in each pond can vary depending on several factors, such as stocking density, pond area, and shrimp growth stage (Day of Culture/DoC). Ponds with high stocking densities require more aerators than ponds with lower stocking densities. The size of the aerator should also be adjusted to the pond area to ensure sufficient oxygen distribution. The same applies to the shrimp growth stage.

In the initial stage, when the shrimp are still in the larval stage, fewer aerators may be needed compared to when the shrimp have grown larger. It is important to ensure that the selected aerators can effectively increase oxygen levels and distribute them evenly throughout the pond. As a guide, an aerator with a 1 Horse Power (HP) rating is considered ideal for supplying oxygen for every 500 kg of shrimp. Furthermore, to determine the number of aerators required, the total biomass of shrimp needs to be estimated first.

3. Choose Rust-Resistant Aerators

Shrimp pond aerators are often exposed to water directly, requiring sturdy construction and materials. The main component that is very vital is the dynamo or engine part. Therefore, it is advisable to ensure that this part has good resistance to water exposure and is not prone to rust.

4. Ensure Aerators Have Easily Accessible Spare Parts

When selecting shrimp pond aerators, it is important to ensure that their spare parts are easily accessible. Thus, if there are any problems or damage to the aerators, you can immediately complete the necessary repairs and maintenance.

Also Read: Understanding the Term “Anti-Dumping” in Shrimp Export

Determining the Number of Required Aerators

To determine the number of shrimp pond aerators required, you need to consider several factors such as the available pond area, shrimp stocking density, available water resources, and proper shrimp pond management. Here are the steps you can follow:

1. Calculate Pond Area

The first step in determining the number of aerators needed for shrimp cultivation is by calculating the pond area. This is because not all ponds are the same size. Make sure you also measure the size of the aerators to fit the pond area you have.

2. Calculate Shrimp Stocking Density

The vannamei shrimp stocking density is also one of the factors that determine the number of shrimp pond aerators you need. The higher the stocking density, the more aerators are required. This is to ensure that the amount of oxygen received by the shrimp remains sufficient even when cultivated at high stocking densities.

3. Determine the Number of Aerators

After knowing the pond area and shrimp stocking density, you can then determine the number of shrimp pond aerators needed. Calculate the number of aerators required based on the pond area and aerator size. Make sure each area of the pond receives sufficient aeration to support healthy shrimp growth.

The Influence of Feed Quantity on the Growth Rate of Vannamei Shrimp

The influence of feed quantity on the growth rate of vannamei shrimp depends on how the feed management for vannamei shrimp is implemented. The amount of feed given to shrimp in ponds will relatively decrease as the shrimp grow. Therefore, giving the appropriate amount of feed will maximize the growth rate of the cultivated shrimp.

Feed for vannamei shrimp is a significant factor in aquaculture, especially in intensive and super-intensive systems. Additionally, feed accounts for up to 70% of the total costs incurred during cultivation. Therefore, to maximize the growth rate of vannamei shrimp, farmers must implement proper feed management.

Also Read: How to Increase the Appetite of Vannamei Shrimp

The Influence of Feed Quantity on Growth Rate

The amount of feed given to vannamei shrimp daily must match the shrimp’s needs in the pond, including nutrition, quantity, and frequency. Indeed, the shrimp growth rate can be influenced by internal factors such as genetics and external factors like nutrition in the feed, stocking density, and pond water environment.

Proper feeding can increase shrimp growth rates, leading to increased average shrimp body weight (ABW). Conversely, underfeeding can result in suboptimal shrimp growth, which in the long run affects the harvest yield.

How to Easily Calculate Vannamei Shrimp Size

Vannamei shrimp size is one of the crucial parameters for determining the success of cultivation. Usually, there is a target size to be achieved for certain post-larval shrimp stages. Therefore, farmers must know how to calculate shrimp size accurately.

Knowing how to calculate vannamei shrimp size accurately can provide many benefits for farmers. This includes feed planning, determining selling prices at harvest, and assessing whether shrimp cultivation is being done correctly.

For those who are not familiar with vannamei shrimp size, here is a summary for you.

Also Read: Understanding the Term “Anti-Dumping” in Shrimp Export

What is Vannamei Shrimp Size?

Size in shrimp cultivation is one of the indicators of successful farming. By knowing the size of the shrimp, you can determine the profit you will get in one cycle because size also determines the selling price to suppliers.

Vannamei shrimp size is a measurement system based on the number of shrimp per kilogram. The smaller the size number, the heavier and larger the shrimp produced. For example, a size 20 shrimp means there are 20 shrimp per kilogram.

Usually, during cultivation, shrimp with a size of 100 already have a market value, so partial harvesting is done. Subsequently, farmers can harvest when the shrimp reach size 90, size 50, and so on.

How to Calculate Vannamei Shrimp Size?

Calculating vannamei shrimp size is not difficult to understand. Usually, shrimp size is measured periodically during cultivation at certain post-larval stages and at harvest. Both are done using sampling methods.

After taking several shrimp for sampling using a scoop net or net, you can calculate the size using the formula:

For example, if sampling is done at post-larval stage 50 and the average body weight of shrimp obtained is 15 grams. Then, the size calculation is as follows:

Size = 1000 grams / 15 grams = 66.67

So, the calculated shrimp size is 66.67 shrimp/kg.

The first tip to achieve optimal shrimp size is to ensure that all water quality parameters are always within the optimal range. Poor water quality can hinder shrimp growth. Moreover, sudden changes in water quality can stress the shrimp.

2. Choose High-Quality Post-Larvae

In essence, selecting high-quality post-larvae is the key to successful vannamei shrimp farming, including achieving optimal shrimp size. Incorrect selection and uncertified post-larvae can result in slow growth or increased susceptibility to diseases, making it difficult to achieve optimal size.

Furthermore, improper post-larvae stocking can lead to suboptimal shrimp growth. For example, excessive exposure to direct sunlight, stocking post-larvae without prior acclimatization, neglecting water quality, and overstocking.

3. Implement Best Operational Management

Implementing good operational management of shrimp ponds can also be a factor in achieving optimal shrimp size or not. Operational management includes feed management, water quality management, and daily shrimp maintenance.

4. Ensure Shrimp Nutrition is Met

When conducting intensive to super-intensive vannamei shrimp farming, providing feed and other supporting nutrition is crucial for optimal shrimp growth. Make sure to provide feed suitable for shrimp age, both in terms of nutrient composition and quantity.

5. Conduct Regular Sampling

To monitor the growth of your shrimp size and determine whether your shrimp are growing optimally, you need to conduct regular sampling. This sampling is very useful for checking the overall condition of your shrimp, including their health.

Function of Anco Shrimp Pond and How to Use It

Anco shrimp pond is a type of pond equipment that must be present in every shrimp pond. This tool is useful for monitoring the condition of shrimp through sampling, including in terms of feeding and monitoring the health conditions of the shrimp.

Anco is usually made of circular or square-shaped netting. This shrimp pond equipment is usually installed on each side of the pond, while the number varies according to the size of the pond.

Now, how do you use anco? Find out more in this article!

What is Anco Shrimp Pond?

Anco is shrimp pond equipment useful for sampling, both for controlling feed and shrimp health. Usually, anco is checked every day to detect anomalies, so that special treatments can be given immediately.

Anco are usually made of nets with various shapes and sizes. These shapes and sizes are adjusted to the needs of each pond. Typically, the size of anco ranges from 80 cm to 100 cm.

For vannamei shrimp ponds with an area of less than 0.4 hectares, the recommended number of ancos is between 2-4. Shrimp ponds with an area between 0.4-0.5 hectares should use 4 ancos. Shrimp ponds with an area between 0.6-0.7 hectares should use 5 ancos. And shrimp ponds with an area of 0.8-1 hectare should use 8-10 ancos.

Functions of Anco

1. Monitoring the Efficiency of Shrimp Feed Usage

The first function of anco is to monitor the efficiency of shrimp feed usage. Feed efficiency can be observed when the amount of feed given matches the needs of the shrimp for optimal growth. Therefore, shrimp farmers should not overfeed or underfeed.

You can adjust the amount of feed based on the age and estimated average weight of the shrimp. It is advisable to regularly check whether your shrimp are consuming the feed properly or not. This checking is usually done using anco.

2. Monitoring Shrimp Health

The next function of anco is to monitor the health of shrimp in the pond. You can sample by taking shrimp from anco and routinely checking their health conditions so that if anomalies occur, action can be taken promptly.

3. Sampling Shrimp Conditions

Routine sampling of shrimp conditions is usually also done with the help of anco in each pond. Anco, in this case, facilitates the retrieval of shrimp.

How to Install and Use Anco in Ponds

To install anco in shrimp ponds, you can follow these steps:

  1. Prepare the anco and evenly spread the feed inside it.
  2. Slowly submerge the anco into the pond water.
  3. Wait for a moment until the shrimp consume the scattered feed.
  4. Lift the anco carefully and check for remaining feed and shrimp reactions to the feed.
  5. After installing the anco in the shrimp pond, you can start sampling to determine the shrimp feed consumption rate.
