Tiger Shrimp vs Vannamei Shrimp, Which One is Better for Cultivation?

Tiger shrimp vs vannamei shrimp is a topic always sought after by farmers. Especially for those who want to get into the world of shrimp farming. This is because vannamei shrimp and tiger shrimp have their advantages and disadvantages in cultivation.

Both vannamei shrimp and tiger shrimp are fishery export commodities with astounding numbers in Indonesia. Tiger shrimp is a sea shrimp native to Indonesia. In contrast, vannamei shrimp are shrimp that come from the Pacific Ocean.

Before choosing the type of shrimp you want to cultivate, you must first know the differences between the following tiger and vannamei shrimp. Read more in this article!

The difference between Vannamei Shrimp and Tiger Prawn

Tiger shrimp (Penaeus monodon) is a sea shrimp native to Indonesia and has long been a mainstay of fishery export commodities. This shrimp has a distinctive striped pattern on its shell which makes it nicknamed The Black Striped Shrimp.

In their growth, tiger shrimp can reach a length of 35 cm and weigh up to about 260 grams. No wonder this shrimp has always been the belle of the world of aquaculture in Indonesia for years.

Meanwhile, vannamei shrimp (Litopanaeus vannamei) just entered Indonesia in 2001. This shrimp originally comes from the Pacific Ocean region and also has a high level of market demand.

In contrast to tiger shrimp, vannamei shrimp have smaller body sizes with transparent white body colors. This makes vannamei shrimp also known as white shrimp.

Choose Vannamei Shrimp or Tiger Shrimp for Cultivation?

Tiger shrimp vs vannamei shrimp cannot be directly compared. Both have their advantages for the shooters.

Before cultivating vannamei shrimp popular in Indonesia, tiger shrimp was the leading choice for farmers. However, the fame of the tiger prawns had declined due to an outbreak of white spot syndrome that attacked.

At that time, the mortality rate of tiger shrimp due to white spot disease reached almost 100% in just seven days. Because they don’t want to take risks, many farmers switch to vannamei shrimp.

Even so, market demand for tiger shrimp is still very high. So tiger shrimp cultivation can still be a profitable business.

Meanwhile, on the other hand, vannamei shrimp from the Pacific Ocean region seemed to steal the spotlight that tiger shrimp previously owned. Vannamei shrimp comes with various advantages when cultivated.

Some of the advantages of vannamei shrimp compared to other species include the following:

  • Being able to cultivate them with high stocking densities.
  • Being more resistant to disease and poor environmental quality.
  • Having a high survival rate.
  • A short cultivation time of around 90-100 days per cycle.

All those advantages above make vannamei shrimp superior when compared to tiger shrimp.

Things to Look For When Cultivating Vannamei Shrimp

1. Pond Location

Before starting vannamei shrimp farming, the first thing you have to do is choose an appropriate pond location.

According to the Ministry of Maritime Affairs and Fisheries, pond locations for aquaculture activities must meet the following requirements:

  1. In accordance with the spatial use and area designated for shrimp farming activities.
  2. Close to water sources with sufficient quality and quantity for cultivation.
  3. Free from flooding and contaminants.
  4. Have adequate infrastructure.

2. Choose Superior Shrimp Fry

Healthy and ideal fry have a big impact on the success of the shrimp farming process. Therefore, it is important to choose superior fry. The criteria for excellent seeds include the following:

  1. Certified shrimp seeds.
  2. Not infected with WSSV, TSV, IMNV, or IHHNV viruses.
  3. Visually have a uniform size.
  4. Seeds are properly transported under applicable standards.

3. Pay Attention to the Time of Spreading Fry

In cultivating vannamei shrimp, the fry must be stocked appropriately. Special preparations include the selection of time before the seed stocking is carried out.

Some things that must be considered before spreading vannamei shrimp fry are:

  1. Make a temperature adaptation first to the fry that will be stocked.
  2. Add artemia feed.
  3. When stocking is done in the morning or evening.

4. Effective and Efficient Feed Management

Nearly 60% of capital in cultivation is spent on purchasing feed. So, by carrying out effective and efficient feed management, farmers can reduce the money spent.

Effective and efficient feed management can be done by adjusting the feed dose given to vannamei shrimp with the consumption rate. In addition, sampling every few days must also be done to control growth.

5. Always Monitor the Water Quality

Monitoring or observing water quality aims to monitor changes or fluctuations in water quality parameters during cultivation. Ideally, water quality observations are carried out every day at certain hours.

Parameters in observing water quality include physical parameters such as pH, temperature, DO, and salinity; chemical and biological parameters such as alkalinity, TOM, the abundance of plankton species, total bacteria, total vibrio, nitrite, nitrate, phosphate, ammonia, and total suspended solids.

Advantages of Vannamei Shrimp Cultivation

Vannamei shrimp farming can be profitable, with billions of rupiah in turnover. Moreover, if managed on a large scale. No wonder more and more people are interested in getting into this business.

The high interest in the global market for vannamei shrimp is also another trigger where in recent years, vannamei shrimp cultivation has mushroomed in various regions in Indonesia.

In addition, other factors such as vannamei which has a cultivation cycle of only 3 months, can be cultivated in various types of ponds ranging from traditional to super-intensive, has good adaptability, and has a high survival rate making shrimp farming very profitable for farmers.

Disease

Get to Know the Covert Mortality Nodavirus (CMNV) which Can Attack Vannamei Shrimp

Covert Mortality Nodavirus

Covert Mortality Nodavirus or CMNV, is a pathogen in vannamei shrimp that causes VCMD or Viral Covert Mortality Disease. This disease causes shrimp to die at the bottom of the pond, which makes it difficult for farmers to detect them from the start.

The CMNV virus in shrimp was first discovered in China in 2009 with a mortality rate of up to 80%, causing huge economic losses for the farmers there.

However, it is also possible that this vannamei shrimp disease will spread to Indonesia if it is not prevented and handled properly. Therefore, in this article, let’s learn more about the Covert Mortality Nodavirus (CMNV)!

Also Read: Get to Know Vannamei Shrimp Probiotics and Its Benefit

Life Stadia of Shrimp that are Vulnerable to CMNV

In white shrimp, mortality due to Covert Mortality Nodavirus (CMNV) was found in the first month after stocking up to 60-80 days after stocking. However, shrimp from various stages are also potentially infected with this virus.

Therefore, farmers need to detect early on the presence of the virus that causes Viral Covert Mortality Disease.

Vertical transmission of this disease can also occur. In previous studies, it was known that wild shrimp E. Carinicauda was strongly suspected of being an intermediary for CMNV to spread to ponds.

Meanwhile, a study by Liu (2018) showed that Covert Mortality Nodavirus (CMNV) could be detected in oogonia, oocytes, spermatocytes, fertilized eggs, and nauplii.

Symptoms of CMNV Affected Shrimp

Shrimp waning due to Covert Mortality Nodavirus (CMNV) usually stays at the bottom of ponds rather than swimming on the surface. Over time, these shrimp will die. Therefore, CMNV disease is also referred to as “bottom death”.

While clinically, several symptoms are shown, including necrosis and atrophy of the hepatopancreas, empty stomach and intestines, softening of the outer shell of the shrimp, slowing growth, white muscles, and experiencing necrosis.

CMNV Diagnostic Methods

Covert Mortality Modavirus

Diagnosing shrimp infected with Covert Mortality Nodavirus (CMNV) can be done using various methods, including Reverse Transcription Loop-mediated Isothermal Amplification (RT-LAMP), Nested Reverse Transcription PCR, gene sequencing, histopathology, RNA in-situ hybridization (ISH). Meanwhile, virus particles can be observed with Transmission Electron Microscopy (TEM).

How to Prevent CMNV in Vannamei Shrimp

As previously explained, the carrier part of the Covert Mortality Nodavirus (CMNV) comes from wild shrimp and other aquatic animals. Therefore, you must always be vigilant and monitor the possibility of this transmission.

In addition, considering that Covert Mortality Nodavirus (CMNV) can be detected early, make sure you cultivate shrimp fry that is healthy and free from various types of diseases.

Find Out About CMNV and How to Handle It with DELOS!

Covert Mortality Nodavirus (CMNV) has a death rate of nearly 80% of the total shrimp population in ponds. Moreover, this disease is also not easily detected by the farmers considering that the infected shrimp will tend to stay at the bottom of the pond.

So it is very important to carry out routine checks and early detection of the CMNV virus that causes VCMD or Viral Covert Mortality Disease.

If you still need to figure out where to consult, DELOS is here and ready to help you. Together with a scientific team that has experienced for years and turns them off, DELOS is prepared to help you in handling if a disease is detected in your shrimp pond.

7 Characteristics of High-Quality Vannamei Shrimp Seed

Quality vannamei shrimp seed is the key to the success of the cultivation that you are doing. Therefore, choosing the right one with high quality is essential to get optimal results.

Several tests are performed to determine the quality of shrimp seed. Among them are PL quality, origin and reputation of the hatchery, visual and stress evaluation, and other tests to detect if pathogens are present.

Therefore, here are the characteristics of high-quality vannamei shrimp seed that you should know to make the right choice.

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

1. Uniform Shrimp Seed Size

The first characteristic of high-quality vannamei shrimp seed can be seen from the uniform sizes of the shrimp seed. This non-uniform size indicates that the shrimp seed grows normally and receives the same nutritional intake.

In addition, the uniform size of shrimp seeds can also prevent cannibalism and competition for food with each other.

2. Shrimp Seed Not Physically Disabled

Several essential criteria must be filled in by high-quality vannamei shrimp seed before stocking. One of them is the physical equipment of the shrimp seed itself.

Healthy vannamei shrimp seed must have complete and well-developed limbs. From the tail that is not curved, the eyes and eye stalks are perfectly shaped, to the utterly intact swimming legs.

3. Shrimp Seed Has Fully Filled Gut

The external physical condition of the vannamei shrimp seed should also be examined for the state of the inside of the body, namely the gut. A vannamei shrimp seed is healthy when it has a filled intestine which is a sign that it is eating well.

On the other hand, vannamei shrimp seed with an empty gut condition can mean that the shrimp seed has no appetite or is even experiencing stress.

4. Right Move Actively

The next characteristic of high-quality shrimp seeds is shrimp seeds move by actively swimming here and there, which is done by activity testing. This is because the shrimp seeds are sensitive to external stimuli.

5. Free from Various Diseases

The shrimp farming industry has been affected several times by outbreaks of diseases caused by viruses and bacteria. Therefore, it is crucial to know whether you have certain conditions. This is done to prevent the farmers from losses.

Usually, a Polymerase Chain Reaction (PCR) test is carried out through a strict population sampling protocol to determine whether it is genuinely disease-free.

6. Pass the Stress Test

Minimizing stress on vannamei shrimp seed is a top priority during the hatchery process. From the time at the hatchery, the trip to the pond, until the stocking time.

This is because stressed shrimp seeds, when released into the environment to enlarge, will be potentially hostile to each other and less likely to survive.

7. It comes from a Trusted Hatchery

Finally, to get vannamei shrimp seed of the highest quality, you can get them from a trusted hatchery or hatchery. With a well-monitored hatchery process, farmers don’t have to worry about the quality of the shrimp fry they buy.

Getting to Know the DOC Term in Shrimp Farming

You must be familiar with DOC or Day of Culture, right? The term DOC in shrimp farming refers to the days when white shrimp and other shrimp are cultivated. DOC is calculated from the time the seeds are sown into the pond until the harvest.

In vannamei shrimp culture, DOC is also used as a benchmark for the age of shrimp after the larval stage. For example, DOC 80 means that shrimp farming has been carried out for 80 days since the first day the fry were sown.

Are you still confused about what DOC or Day of Culture is in shrimp farming? Come on, read this article to the end to find the answer.

When you are new to the world of aquaculture, maybe you find tons of new terms on this industry. One of the is DOC shrimp or Day of Culture. 

The term DOC in shrimp farming means the days during which the cultivation of vannamei shrimp in the pond takes place. This DOC begins to be calculated from when the fry stokes into the pond until the shrimp are harvested. Other than that, DOC is also used to calculate the age of shrimp in ponds which is also important for shrimp feed management.

Most people still don’t know the difference between PL and DOC in shrimp farming. However, they are two different terms because both are often interpreted as referring to the shrimp’s age.

PL stands for Post Larva. This term indicates the shrimp fry’s age, generally in days. PL vannamei shrimp counts after the shrimp complete the mysis stage until it is ready to be stocked in the pond. For example, PL1 means the fry is only one day after completing the mysis stage.

After the PL (Post Larva) is stocked into the pond, the term to indicate the shrimp’s age is changed to DOC or Day of Culture. For example, DOC 30 means that the shrimp fry has been 30 days old since they were stocked into the pond. So, don’t be confused with the term both PL and DOC.

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

Vannamei is a type of shrimp that has the best environmental resistance compared to other types of shrimp. This is supported by the presence of organ systems and morphology in vannamei shrimp.

Like humans, vannamei also has a digestive system, respiratory system, circulatory system, nervous system, and reproductive system. All of these organ systems must work properly for the vannamei shrimp to survive.

Curious about the organ system and morphology of vannamei shrimp? Let’s find out the answer to this article.

Also Read: 10 Types of Shrimp for Aquaculture and Aquascape

Morphology of Vannamei Shrimp

Source: freepik.com/topntop26

 

Overall, the morphology of vannamei shrimp is divided into two parts, namely the head and body parts. The head consists of eight thoracic segments and five fused head segments. Therefore, the head of this shrimp is also known as the cephalothorax.

The head of the vannamei shrimp is protected by a shell that tapers forward and is called the carapace. In addition, there is also a pair of compound eyes, a mouth with a jaw (mandible), a pair of antennae, a pair of head fins (scophocerit), a pair of auxiliary jaws (maxilliped), and five pairs of walking legs (pereopod) on the head.

The morphology of vannamei shrimp body parts consists of six segments, they are three tergum segments and three pleuron segments. In this part of the body, five pairs of swimming legs (pleopods) and fan tails are also found which are formed from uropods and telsons.

Organ System in Vannamei Shrimp

1. Digestive System

Vannamei shrimp have a digestive system that is divided into three segments, they are foregut, midgut, and hindgut that are connected to each other. These three parts are covered by a peritrophic membrane that serves as a barrier. Usually, this digestive system can be seen quite clearly on the back of the shrimp.

The foregut digestive tract is located in the cephalothorax, starting from the mouth, esophagus, and stomach. The midgut digestive tract is located extending from the cephalothorax to the 6th segment of the shrimp stomach. Lastly, the hindgut of the digestive tract is located at the back.

2. Respiratory System

Gills are the respiratory organs of vannamei shrimp and other crustaceans. In vannamei shrimp, there are a pair of gills enclosed in a branchial space. These gill structures are classified as dendrobranchiate gills. When shrimp breathe, gas exchange takes place in the gill lamellae.

Apart from being an organ for breathing, the gills of the vannamei shrimp also plays several other important roles. Starting from maintaining salt and water balance, ammonia excretion, and calcium absorption, to acting as a filter for foreign particles in the hemolymph.

3. Circulatory System

Even though it has a transparent white body, it turns out that vannamei shrimp also has a circulatory system like humans. This circulatory system consists of the heart, hematopoietic sinuses, hematopoietic tissue, and lymphoid organs.

The vannamei shrimp’s circulatory system is classified as a semi-open circulatory system with the heart located dorsally in the cephalothorax.

4. Nervous System

You must be familiar with the phrase “shrimp brain”, right? However, in contrast to the phrase “shrimp brain” which means stupid, the brain in vannamei shrimp has an important role in the nervous system.

The nervous system of shrimp and other crustaceans consists of a brain located in the dorsal part of the cephalothorax as the main control center that is connected to all parts of the shrimp’s body. The brain consists of three parts, which are the protocerebrum, deutocerebrum, and tritocerebrum.

5. Reproduction System

The male vannamei shrimp reproductive system consists of a pair of testes, vas deferens, and ejaculatory ducts or terminal ampoules. While the spermatids are produced in spermatogonia with maturation in the seminiferous tubules.

While the female vannamei shrimp reproductive system consists of paired ovaries that extend from the middle of the thorax to the posterior end of the pleon and oviduct. Because shrimp have an external reproductive system, female shrimp have a genophore channel located on the third pereiopod to release eggs that are ready to be fertilized.

DELOS’ 1 Year Journey to Be the Leader of the Blue Revolution

Today, exactly one year after DELOS started our ambitious goal to make Indonesia the largest shrimp producer in the world. To become the leader of the blue revolution by equipping farmers with science-based technology and the best end-to-end operational farm management.

This aspiration began when Guntur Mallarangeng, Bobby Indra Gunawan, Aris Noerhadi, and Alexander Farthing presented a multidisciplinary team that combined aquaculture, marine biology, technology, as well as business management as a unit.

The founders of DELOS saw an opportunity for Indonesia as the largest maritime country in the world with a coastline of 95K kilometers. However, this is not equal to the total quantity of existing shrimp exports. Of the total shrimp farms in Indonesia, 75% of them can only contribute 10% of the export quantity.

This is where DELOS started its journey as the leader of the blue revolution for Indonesian aquaculture. Assist and support farmers to increase their shrimp farms’ productivity.

Equip Farmers with Technology

In June 2022, DELOS successfully launched the AquaHero app which has been developed since the end of 2021. This application is a combination of science, technology, and operational management to make it easier for farmers to monitor and increase the productivity of their shrimp farms based on data.

AquaHero uses modern data collection methods and state-of-the-art scientific methods to estimate the treatment required while minimizing risks in shrimp farming. This system has been implemented in shrimp farms that are part of the DELOS ecosystem.

The AquaHero app is still being developed, both in terms of performance, usage procedures, and user interaction. However, farmers can already feel the flexibility in monitoring the condition of their shrimp farms.

One year into the process of developing Indonesian aquaculture, DELOS has succeeded to manage up to 195 Ha of intensive and super-intensive shrimp farmlands spread throughout Indonesia. However, there are still hundreds of hectares of other pond areas that require a DELOS touch.

The increase in pond productivity continues to occur as a result of our operational management and the best team we have. Of all the ponds that have been managed, DELOS has succeeded in increasing the productivity of the average yield by up to 2x from the previous one.

Not only that, but DELOS is also able to mitigate potential losses due to disease with a series of tight water quality and shrimp health tests as an early detection system developed in the ponds we manage. In terms of profitability, our management team monitors the operational costs of the pond from day to day, so that the shrimp farming capital spent by the farmers is expected to be more efficient.

Create Competent and Professional Human Resources in Aquaculture

DELOS also focuses on sustainable aquaculture in the future for Indonesia. Efforts to increase the production and productivity of the aquaculture industry must be balanced with the availability of reliable human resources (HR) so that growth is sustainable. One of the biggest challenges, when we develop a fishery business in an area, is the need for human resources who understand and master the needs, diversity, and dynamics of the sector. This is the background for the birth of DELOS Maritime Institute (DMI) as one of the best aquaculture training programs in Indonesia.

DELOS Maritime Institute not only targets final semester students and fresh graduates but also invites farmers and fishermen’s children to participate as participants. The introduction of fishery business (on farms) usually tends to be done in areas close to the sea or the coast which are generally geographically far from urban areas. Areas that are far from the city make it difficult for people living on the coast to get access to quality education. On the other hand, the fishery business has a social responsibility to absorb the majority of the workforce from the community around the business environment so that the benefits are felt by the surrounding community. DELOS wants to facilitate the nation’s children who want to learn directly in the field of aquaculture, especially shrimp farming.

Currently, preparations are underway to welcome DMI Batch 2 which will begin on October 17, 2022. While previously, DMI Batch 1 had been successfully implemented and managed to graduate as many as 13 participants.

Through DELOS Maritime Institute, we hope that all the knowledge and experience gained by the participants during the program can be useful as a provision to enter the fishing industry. In the future, it is hoped that DMI will become a training institution in the field of aquaculture that can be connected to all ponds in Indonesia and is planned to have a Professional Competency Certification.

Continuing the Journey As the Leader of Blue Revolution

DELOS is more than just an aqua-tech company. It is a mission, a deep commitment to helping farmers in their business development, improving their farms’ productivity and the quality of their lives as well as protecting the environment sustainably.

The dream of turning Indonesia into an international shrimp exporting powerhouse is not easy to achieve. However, with well-managed natural and human resources potential, DELOS believes this dream will soon be realized.

Entering a new age, with a firmer step as the leader of the blue revolution, DELOS will continue to strive to realize the shared dream of making Indonesia the largest shrimp producer in the world.

One year of DELOS, let’s lead the blue revolution!
