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.

Morphology of Vannamei Shrimp

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.

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.

Increase Farms Productivity Up to 2X

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.
