5 Types of Shrimp Pond Aerators and Their Functions

A shrimp pond aerator is one of the main components in aquaculture, especially in intensive and super-intensive ponds. An aerator is a tool that serves to dissolve free oxygen into pond water.

The existence of a water wheel and other supporting equipment for shrimp growth in aquaculture is intended so that ponds can become a comfortable ecosystem for shrimp growth. So that shrimp can grow optimally.

Shrimp pond aerator functions to create aeration. Aeration is a process of increasing the oxygen content in the aquatic environment to ensure that the organisms that live in it get an adequate supply of oxygen and live healthily.

In this article, let’s discover the types of waterwheels commonly used in shrimp ponds and their functions!

The Function of the Shrimp Pond Aerator

  1. Increasing the supply of oxygen in the water stabilizes the biological processes of shrimp.
  2. Ensuring the shrimp get an adequate supply of dissolved oxygen
  3. Improve the quality of the water where shrimp live.
  4. Helps distribute nutrients and feed evenly into the pond.
  5. Make it easier for pond bottom manure to be directed to the disposal center so that the pond bottom is easier to clean.

Types of Pond Aerators

1. Pond Waterwheel with Paddle Wheel

In terms of performance, the paddle-wheel water wheel is the most effective aerator on the pond surface. The parts consist of a frame, motor, float, clutch, deceleration engine, bearings, and paddle wheel.

This waterwheel works by splashing water into the air and capturing oxygen to increase the DO content. The more bubbles produced, the more oxygen is captured.

2. Spiral Aerators

A spiral aerator is an improvised form of a paddle-wheel water wheel, the difference being the shape of the wheels. As the name suggests, this aerator wheel is spiral. In addition, there are several other differences, such as reducing the gearbox or reducer, handle, and connecting shaft.

Meanwhile, in terms of how it works, spiral aerators also sprinkle water into the air to capture oxygen. However, it gets many more bubbles than a regular paddle wheel waterwheel.

3. Pump Sprayer Aerator

A pump aerator is a type of aerator that works by drawing water into a vertical tube and then sprinkling it into the air to capture oxygen. The water will be deflected radially and then fall back to the surface in an umbrella-like pattern.

This type of aerator is widely chosen because it does not require much special care. However, its use can only reach a small area, while it needs to be optimal in large sizes.

In-use pump aerators are usually used in small ponds or can also be used in large ponds but in combination with other types of aerators.

4. Vertical Pump Aerator

A vertical pump aerator has the same working principle as a pump aerator, which is to draw water into the pump tube and then sprinkle it into the air.

Vertical pump aerators are more suitable for small ponds up to 0.25 Ha because the splash produced by this aerator is not as big as a waterwheel. Meanwhile, the capacity ranges from 1 kW to more than 50 kW.

5. Jet Aerators

The jet aerator consists of a shrimp pond water wheel composed of a frame, air suction pipe, propeller, and driving motor. Unlike other types of aerators, the propellers of this aerator are in the water.

The way it works starts with a propeller rotating in the water and sucking in air from outside the pool through a pipe. After the air is sucked in and enters the water, bubbles will appear, indicating that the oxygen supply is starting to enter.

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

Alkalinity in shrimp ponds is the capacity of pond water to neutralize acid, which is measured based on its constituent components in the form of bicarbonate ions (HCO3-), carbonate (CO32-), and hydroxide (OH-). Alkalinity is an important parameter of water quality and influences the success of cultivation.

Alkalinity is also a buffer or water pH buffer. Stable water pH is crucial for shrimp growth because any fluctuation outside the optimum limit can cause stress, decreased growth rate, susceptibility to disease, and even death.

Water in an aquaculture system can come from direct watershed runoff, rivers, lakes, estuaries, seas, or wells with varying alkalinity values. If the alkalinity is low, liming is usually done to increase it.

What Is Alkalinity in Shrimp Pond?

Alkalinity is the ability of water to buffer pH by neutralizing hydrogen cations using water anion components which include bicarbonate ions (HCO3-), carbonate (CO32-), and hydroxide (OH-). Therefore, alkalinity is an important water quality parameter in shrimp ponds.

Maintaining optimal alkalinity in shrimp ponds is critical to stabilizing pH levels, which can affect shrimp health and growth. Optimal alkalinity in shrimp ponds ranges from 130-180 ppm.

Alkalinity below the optimum range in shrimp ponds can cause pH fluctuations. This can cause stress to the shrimp and increase the risk of disease outbreaks. Agricultural lime is usually added gradually to overcome this until it reaches the optimum alkalinity range.

Factors Affecting Changes in Alkalinity

The alkalinity may remain constant, increase, or decrease during the shrimp culture period. Occasionally, the reduction may be so drastic as to require additional liming to keep the alkalinity within the optimal range.

1. Adding Water to the Pond

Adding water to pond ponds can often cause the alkalinity to change. For example, the alkalinity will decrease when a pond gets additional healthy water. To overcome this, farmers need to add limestone, which will dissolve and increase the alkalinity of the water.

2. High Rainfall

In addition, high rainfall can also affect changes in pond alkalinity. Significantly when water evaporation exceeds precipitation, which causes alkalinity to increase. On the other hand, if the precipitation is higher, the alkalinity will decrease because rainwater usually does not contain measurable alkalinity.

3. Denitrification Process

Denitrification, or the process of reducing nitrate to nitrogen gas by bacteria that occurs in ponds, can also increase the alkalinity of the water. This is because denitrification releases one hydroxide ion for every nitrate ion converted into nitrogen gas. While the nitrification process releases two nitrogen ions for every ammonium ion converted to nitrate.

Tips to Increase Alkalinity Value in Shrimp Ponds

1. Increase Alkalinity in Shrimp Ponds with Addition of Dolomite (Calcium Magnesium Carbonate)

Dolomite is widely used to increase alkalinity values. This is because dolomite is also rich in calcium, magnesium and carbonate. With the addition of dolomite lime, the alkalinity of the water can be appropriately maintained.

2. Soda Ash (Sodium Carbonate)

Soda sodium carbonate can also be used to increase the alkalinity of water. However, its use is better done by adding it little by little in one day to hold pH variations properly.

3. Increase Alkalinity in Shrimp Ponds with Baking Soda (Sodium Bicarbonate)

Lastly, baking soda can also be used to increase the alkalinity value of water. Applying sodium bicarbonate is also the same: mixing it gradually into the pond water.

Vannamei Shrimp DOC 20, How is it Growing and How is the Feeding?

During cultivation, the growth of vannamei shrimp must constantly be monitored, including vannamei shrimp DOC 20. This is because this type of shrimp has a faster growth rate when compared to other kinds of shrimp.

For farmers, understanding growth patterns during vannamei shrimp cultivation are very important for successful cultivation. This is because the growth of vannamei shrimp also affects the feeding given to the shrimp.

So how is the growth of vannamei shrimp DOC 20, and how is the feeding? The following is an explanation we have summarized especially for you, which can be used as a reference.

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

Vannamei Shrimp Growth DOC 20

Vannamei shrimp DOC 20, which is still at the beginning of cultivation, has an ideal growth rate of 1-2.5 grams per week. At the same time, the ideal weight is approximately 2 grams per head.

This ideal growth can be obtained if the number of shrimp populations in the pond is by its capacity. On the other hand, if the pond has excess capacity, the growth of the vannamei shrimp in it can be lower than the ideal growth average.

So, how do you cultivate vannamei shrimp DOC 20 or, more precisely during the early stages of cultivation? Like aquaculture in general, farmers must continue to control shrimp and pond water conditions every day. This is useful for detecting more quickly if anomalies in shrimp growth and water conditions can harm aquaculture.

Also Read: These are 7 Tips for Successful and Profitable Vannamei Shrimp Harvest

Vannamei Shrimp DOC 20 Cultivation

Vannamei shrimp cultivation always uses the age or day of culture (DOC) of shrimp as a benchmark in carrying out various actions related to pond management, one of which is how to feed it.

Feeding based on the age of the shrimp is helpful to prevent shortages or excess feed during cultivation which can inhibit the growth of vannamei shrimp.

Meanwhile, how to feed shrimp aged 20 days can be done by blind feeding method. While the type of feed given is in the form of granules with a frequency of 4 times a day and a feed dose of 25-15%.

This type of granule feed is suitable for shrimp from the age of 16 days to 45 days. Meanwhile, granules can be replaced with pellets until the vannamei shrimp are ready to harvest.

What is Aquaculture and Why is It Important?

What is aquaculture? Aquaculture is an action to breed, raise, and harvest aquatic organisms such as fish, shellfish, and crustaceans in a controlled environment, including ponds and tanks, by humans.

With increasing population, economic prosperity, and urbanization globally, the need for food is also growing. Meanwhile, we must rely on something other than capture fisheries that depend on nature. Therefore, aquaculture plays an essential role in meeting the demand for food.

Aquaculture has provided more than half of all fishery products we eat every day. In a way, aquaculture is the fastest-growing food-producing sector in the world and is playing an essential role in helping to meet food needs as the human population continues to grow.

What is Aquaculture?

What is aquaculture? Aquaculture is the production of aquatic organisms under controlled conditions throughout part or all of their lifecycle, with the majority being seafood such as fish, crustaceans, and shellfish. This activity is similar to agriculture, but the difference is what is bred in marine organisms.

To date, aquaculture is the fastest-growing food sector in the world. Moreover, with aquaculture, more sustainable seafood production activities can be carried out without damaging the environment.

Various types of aquaculture have been carried out until now. Cultivation purposes, operational techniques, and hydro-biological features distinguish these species. Meanwhile, shrimp and fish farming is arguably the most widely practised type of aquaculture worldwide.

Cultivating shrimp, fish, and other marine organisms is almost the same, starting with preparing ponds, seed selection, feeding and care, water quality management, and harvesting.

Why is Aquaculture Important?

Overfishing in the ocean continues to increase from year to year. This is because the increase in the human population makes the need for food also increase. Therefore, we need other alternatives to meet the needs of this seafood.

So, where lies the role of aquaculture? That being said, aquaculture is the right way to meet this seafood supply need. By cultivating aquatic commodities responsibly and sustainably, we can meet the needs of healthy protein for future generations while still being environmentally friendly.

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.

Also Read: DELOS’ 1 Year Journey to Be The Leader of The Blue Revolution

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.

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!
