Using Probiotics for Shrimp Health, What’s the Impact?

Vannamei shrimp cultivation has experienced a significant increase in recent years. This is a result of the increasing demand for seafood on a global scale. However, the threat of disease and other health challenges that can cause losses in cultivation is very high. This is where probiotics for shrimp play a significant role and become a promising solution to this problem.

The use of probiotics as an additional supplement in animal feed and aquaculture has been going on since the 1970s. The addition of probiotics is intended to increase the growth and health of animals because probiotics can stimulate the immune system.

In this article, we will discuss more about the impact of using probiotics on shrimp health and their potential to increase the success of aquaculture. Come on, read more!

Impact of Using Probiotics in Shrimp Farming

1. Improves Intestinal Health

Probiotics play an essential role in maintaining and improving the intestinal health of shrimp. The presence of good bacteria from probiotics prevents the growth of harmful pathogenic bacteria because they are competitive and form a barrier, so the risk of disease outbreaks in shrimp is lower.

In addition, probiotics also help digest nutrients such as protein, fat and complex carbohydrates to increase the absorption of nutrients for the growth and development of shrimp.

2. Prevent Disease and Improve the Immune System

Shrimp are susceptible to a variety of diseases that can have a devastating impact on the aquaculture industry. Until now, probiotics have been shown to increase the immune system of shrimp and make them more resistant to disease infections.

Probiotics can also stimulate the production of immune-related molecules, such as antimicrobial peptides, which maintain the front lines against pathogens.

Not only that, probiotics can also increase the activity of immune cells, including phagocytic cells and lymphocytes, to enhance the overall immune response of the shrimp.

3. Improving Water Quality

Maintaining good water quality is essential for shrimp’s health and growth. Poor water quality can cause stress, weaken the immune system, and increase susceptibility to disease infections in shrimp.

Probiotics can also contribute to effectively managing water quality in shrimp culture systems. Its presence can assist in the degradation of organic matter, reduce the accumulation of toxic compounds, and improve water conditions.

In addition, probiotics can also play a role in controlling harmful algae or algae and increasing the stability of the pond ecosystem.

4. Instead of Antibiotics

The use of antibiotics in aquaculture is one thing that is highly avoided because of their harmful impact on the environment. Probiotics are an alternative that can replace antibiotics to maintain a healthy microbial balance in shrimp.

By strengthening beneficial microbial populations, probiotics can suppress the growth of pathogenic bacteria. Several types of probiotic bacteria also produce antibacterial substances that can inhibit growth and even kill pathogenic bacteria.

5. Increases Shrimp Survival and Growth Rates

The use of probiotics in shrimp farming has shown promising results, especially in terms of survival rate and growth performance.

Better gut health and disease resistance contribute to higher survival rates and reduced economic losses associated with shrimp mortality.

Probiotics also help improve the quality of the digestive system and absorption of nutrients in shrimp so that shrimp become healthier and have an impact on increasing aquaculture production.

5 Stages of Vannamei Shrimp Pond Preparation Before Doing Cultivation

Cultivating vannamei shrimp pond is a very profitable business. What’s more, vannamei shrimp is a type of shrimp that grows quickly from fry to harvest. That is, one cycle only takes three months.

Vannamei shrimp pond plays a crucial role in aquaculture. Because, in this pond, the shrimp will be raised until they are ready for harvest later. Therefore, you need to prepare the pond well.

This pond preparation aims to support the formation of an ecosystem conducive to maintaining shrimp during one cultivation cycle. What preparations need to be made, and what are the steps? Read more in this article!

Vannamei Shrimp Pond Preparation Stages

1. Pond Cleaning

The earliest preparation for vannamei shrimp pond is the cleaning stage. In this stage, waste disposal is usually carried out, especially organic and phosphate waste accumulated at the bottom of the pond.

While the cleaning method can be done in two ways, namely the dry method and the wet method.

a.) Dry Method

Cleaning vannamei shrimp pond using the dry method uses sunlight to dry them. The trick is to drain and let the shrimp pond be in the sun for 10-30 days.

Furthermore, the waste at the bottom of the pond begins to be cleaned and disposed of in a predetermined place. However, this dry method cannot be applied to all parts of the pond, so it must be cleaned using a wet method.

b.) Wet Method

In areas where vannamei shrimp pond cannot be completely drained, they will usually be cleaned using a wet method. This method is carried out by spraying high-pressure air to remove waste from the previous cultivation cycle.

The wet method has an advantage in terms of time compared to the dry method because it only requires a short time, making it more effective and efficient.

2. Liming

After the vannamei shrimp pond are cleaned, the pond must be filled with water and left overnight before rinsing to remove residual waste and increase the pH. This process must be continuously repeated until the pH of the water is above 7.

When the pH of the water reaches 7, liming can be done. The type of lime used in this process is usually CaCO3 or dolomite lime [CaMg(CO3)2] for pond water with a pH close to neutral. Meanwhile, for water pH below 5, hydrated lime [Ca(OH)2] is used.

In addition, you also have to calculate the amount of lime used carefully. This is to avoid the air pH being too high, which can increase ammonia toxicity and result in death in shrimp.

During the process, lime must be spread over the entire pond bottom and up to the top of the barrier. Most of the lime should also be applied over the feeding area and any parts of the pond that remain wet.

3. Extermination Predators

The next stage of preparation for vannamei shrimp pond is eliminating predators to prevent them from entering the pond area. The way to do this is to filter the water that will be used to fill the pond with a filter with a fine mesh.

These predators or intruders include fish, crustaceans, and other invertebrates that can eat shrimp food or even carry parasites and diseases.

In addition, during the first month of vannamei shrimp cultivation, water should only be added to the pond if the water quality is poor and causes the shrimp not to develop properly. This avoids the entry of competitors or predators for the shrimp.

4. Fertilization

The next step in preparing for the vannamei shrimp pond is fertilization. Shrimp pond must be given fertilizer to stimulate plankton growth to prepare ecosystems and natural food for vannamei shrimp.

Fertilizers must be dissolved before spreading over the pond water surface to avoid fertilizer deposition on the pond’s bottom. This is because the fertilizer settles at the bottom will fertilize the soil and accelerate algae growth.

After fertilization, the plankton will develop in a few days and the water will change color to slightly green.

5. Aeration

The final preparation stage for vannamei shrimp pond is preparing the needs for pond aeration and turbulence. This stage must be carried out based on consideration of production targets, configuration, energy availability, and cultivation systems.

Preparation of aeration aims to ensure the supply of dissolved oxygen, avoid dead currents, direct sediment, and prevent stratification of temperature and salinity in pond water.

The type of aerator used depends on the pond’s area and the water’s depth. For example, a pond with an area of 0.5-1 ha requires four aerators installed in the corners to encourage maximum water flow.

The aerator must be turned on 24 hours before the fry is stocked, so there is enough time to create currents and clean the vannamei shrimp feeding area.

Pond Construction

This is the Ideal Vannamei Shrimp Pond Design and Construction

It is important to have the ideal vannamei shrimp pond design and construction before starting cultivation. This is because ponds are an environment where shrimp grow and develop.

Strong vannamei shrimp pond construction is needed to run the cultivation process well. The construction of these ponds directly affects the management of water, waste, cultivation activities, and harvest.

So, what is the ideal shrimp pond design and construction? Read more in this article.

Also Read: This Is the Best Water Color for Vannamei Shrimp Pond

Ideal Vannamei Shrimp Pond Design

Before carrying out vannamei shrimp farming, farmers must carefully consider the design of their vannamei shrimp ponds. This is because the pond design will affect the cultivation carried out.

In general, things that need to be considered in the design of vannamei shrimp ponds include the length and width of the plot, depth, berm size, bund size, perimeter canal size, and location of the floodgates.

1. Pond Map Design

The shape and area of the pond plots depend on the level of technology used. The shape of the pond that has been chosen is rectangular or square. However, apart from that, there are also circular ponds.

For rectangular pond plots, the longest side should be less than 150 m. This is so that the water flow from one side to the other can cause a fairly strong current.

In addition, the longest side of the pond should be perpendicular to the direction of the wind so that the wind does not cause strong waves of water. Conversely, if the longest side of the pond is parallel to the wind direction, the water waves in the plot will be strong and can damage the bunds.

2. Bund Design

Vannamei shrimp pond bunds must be designed to accommodate the maximum possible water level. The height of the bund must be based on the highest tide ever.

In addition, several things that are no less important to note are that the bunds must be able to protect the delimited area from water pressure. Therefore, it must be ensured that the bunds must be strong enough, not easily broken by water pressure, and not easily eroded.

Generally, shrimp pond bunds are divided into main, secondary, and tertiary bunds. Each of these bunds has a different design and size and has been adapted to its function.

The main bund is a bund that is made around the entire pond area and functions to protect the area from flooding. The main bund design must be given a certain distance from the water source as a buffer area.

Secondary bunds are designed similarly to primary bunds to maintain water levels and are strong enough to withstand water pressure. The recommended width for this secondary bund is 1.5 meters.

3. Channel Design

Shrimp pond channels have two types. The first type is the open type, with the best trapezoidal cross-section, where the water flows following the direction of the earth’s gravity. The second type is the closed type, usually used for intensive ponds and distributes water pumped from the sea.

Shrimp pond channel design is done by determining the slope of the channel, the width of the channel bottom, the capacity of the channel, and the slope of the channel walls

Construction of Vannamei Shrimp Ponds

In constructing vannamei shrimp ponds, various technical aspects must always be considered so that the cultivation is carried out sustainably. From the stages of work to be carried out, labour requirements, processing time, work arrangements, and the amount of equipment needed.

Construction of shrimp ponds must be carried out following the design and layout of the ponds that have been determined previously. In contrast, the work starts with making bunds and laying ponds, canals, and sluice gates.

Based on the Ministry of Maritime Affairs and Fisheries Regulation No. 75 of 2016 concerning General Guidelines for Enlargement of Tiger Shrimp (Penaeus monodon) and Vannamei Shrimp (Litopenaeus vannamei), good shrimp pond construction has criteria including:

Have sufficient water availability during low tide, at least seawater.
Has no dead point.
The bund as an access road in the pond must be passable by vehicles and workers.
Land use and equipment for shrimp ponds must be effective and efficient.
Guaranteed maximum safety and security at work.

In addition, the construction of shrimp ponds must be made in such a way as to ensure the smooth operation of the pond during cultivation. From pond preparation, stocking of shrimp fry, and shrimp enlargement process, to harvest.

Additionally, vannamei shrimp ponds must have an effective and efficient design and construction by adjusting costs incurred without reducing technical functions and maintaining environmental sustainability.

Tips

How to Speed Up the Molting Period in Vannamei Shrimp

As a type of crustacean, vannamei shrimp must experience a period of molting or the release of their outer skeleton. Molting can occur several times throughout the shrimp’s life and growth. So, how do you speed up the molting period for vannamei shrimp?

Molting in vannamei shrimp is a hormonal phenomenon that occurs as it grows. The molting process occurs because the shrimp experience an increase in body volume, while the exoskeleton cannot increase in size due to its rigid nature.

The process of molting in shrimp can fail, which can cause death in shrimp. This is what makes the farmers must know how to improve the quality of the pond environment to expedite and accelerate the molting period in shrimp.

Also Read: This is the Process of Molting in Shrimp and How to Handle It

Molting Stages in Vannamei Shrimp

1. Pre-molt

Shrimp usually pass the first molting phase by preparing its body to release the carapace or outer shell of the shrimp. Usually, the shrimp’s appetite will decrease, and the cuticle layer will begin to grow.

2. Inter-molt

The intermolt phase is the stationary phase where the shrimp cuticle begins to harden. Shrimp mass growth also runs continuously, and their feeding activity is stable or reaches a maximum level.

3. Post-molt

In this phase, the shrimp recover from their previous molt. To strengthen the cuticles and adapt them to their new size, vannamei shrimp will absorb a large volume of water with a high mineral content. The new carapace will harden in a few hours.

Also Read: Do These 5 Things For Successful Vannamei Shrimp Cultivation

Molting Phase Vulnerable to Disease

Molting significantly disrupts the shrimp’s body as it needs time to recover after the molting phase. The cuticle is not yet fully functional, so the shrimp must mobilize its body reserves to harden the weak cuticle.

Shrimp, including the White Spot Syndrome Virus (WSS), are susceptible to diseases in this phase. This makes the farmers must always be aware of the various possibilities that will be faced during the shrimp molting phase.

How to Speed Up Shrimp Molting

Although molting is a natural process in the shrimp body, many possibilities can occur during this phase. If the molting process fails, the worst impact that can happen is the death of the shrimp. In addition, other effects can be shrinking the shrimp’s body and slowing its growth.

Basically, the molting process in shrimp cannot be accelerated, considering that this process occurs naturally and is hormonal. However, farmers can expedite the molting process in the following ways.

1. Ensure Shrimp Are Not Stressed

The first way to speed up molting is to keep the shrimp from getting stressed. If the shrimp experience stress, their growth will be hampered, and the disease risk will increase.

Several factors that can cause stress to shrimp include extreme and too fast changes in water quality parameters and poor feed quality.

For the molting process of the shrimp to run smoothly, the farmers must always check the water quality parameters regularly, ensure that they are always in optimal condition, and ensure the feed given to the shrimp is of high quality and has sufficient nutrition.

2. Check Shrimp Conditions Routinely

To ensure that the molting of the shrimp runs smoothly, use pond sampling techniques and carry out periodic inspections to monitor the progress of the molting process.

Check whether the shrimp shell or carapace has begun to harden or has been released. By checking the condition of the shrimp regularly, farmers can evaluate whether the molting is running smoothly and whether the growth of the shrimp is normal or not.

3. Adjust the Amount of Feed with the Molting Stage

By conducting sampling for routine inspection, farmers can find the stages of shrimp molting so that the amount of feed given can be adjusted according to the stages.

For example, in the pre-molt stage, shrimp tend to eat less. Meanwhile, at the inter-molt stage, shrimp feeding activity peaks, meaning farmers must provide a more significant portion of feed than usual.

Adjusting the amount of feed at the vannamei shrimp molting stage can help keep the shrimp healthy and grow more optimally.

4. Provide Additional Nutrition for Shrimp

Providing additional nutrition for molting shrimp, such as calcium and phosphorus, has a good effect on shrimp for the growth of new shells. This extra nutrition can be in the form of feed nutrition or directly into pond water.

In addition, providing additional essential minerals, protein, and other nutrients to shrimp feed and pond water can also help expedite the shrimp molting process.

This Is the Best Water Color for Vannamei Shrimp Pond

Pond water is an indicator that must always be considered when cultivating. The best color for vannamei shrimp pond is brownish green and dark green. This colors can describe the living conditions of the shrimp in it. However, this color only becomes a benchmark and farmer needs to check it with other indicators regularly.

Each pond can have a different color of the water. This color can indicate the types of organisms that are in it. Through the visible colors of pond water, farmers can identify anomalies and predict if problems arise.

What color of water is the best for vannamei shrimp pond? Let’s learn about it through this article!

Also Read: 5 Types of Shrimp Pond Aerator and Their Function

The Meaning of Pond Water Colors

The color of pond water is not always bright blue like seawater. Many color variants indicate certain conditions in ponds. Here are the meanings of pond watercolors that you need to know.

1. Greenish Yellow

The color of pond water greenish yellow is indicating that the amount of phytoplankton in the pond is still unstable, so TSP or urea is needed. Farmers must carry out routine checks to observe changes when applying this fertilizer. If it is still changing and not stable, farmers can add dolomite lime.

2. Brownish Green

When pond water is green-brown, it means that the water contains sufficient phytoplankton. This color is the best color for vannamei shrimp pond. However, to maintain its stability, it is necessary to apply fertilizer every week.

3. Blue Green

The bluish-green color in vannamei shrimp ponds indicates abundant blue-green algae phytoplankton. This shows that there are porous shrimp, and it is necessary to replace the water, add dolomite lime, and apply TSP fertilizer.

4. Dark Green But Not Concentrated

The color of pond water is dark green, indicating that the amount of phytoplankton in the water is relatively stable. This color is the best water color for vannamei shrimp pond. Meanwhile, to optimize it, farmers can give a little TSP fertilizer while continuing to observe if there is any changes.

5. Deep Dark Green

When pond water is thick dark green, and feels slimy, this indicates that there is toxic phytoplankton which can cause many shrimp to get sick. Of course, this color is not the best color for vannamei shrimp pond and farmer must avoid it.

But there is no need to worry about overcoming this can be done by replacing water and giving dolomite lime.

6. Dark Brown

The dark brown color of pond water indicates a lack of phytoplankton growing in it. To overcome this, urea and TSP fertilizers can be used, and further land reclamation is needed.

7. Reddish Brown

When the color of the pond water is reddish brown, this indicates a high content of toxic phytoplankton and sulfuric acid. To deal with this, you need to neutralize it by changing the water, giving lime, giving urea fertilizer, and rinsing the pond repeatedly.

8. Black

The black pond water color indicates that the phytoplankton is not growing properly. In addition, this color can also be an indication of the amount of decaying organic matter at the bottom of the pond. Of course, this color is not the best water color for vannamei shrimp pond.

The only way to overcome this condition is to remove the sludge that has settled at the bottom of the pond until it runs out.

Indicators of Pond Water Quality

Knowing the quality of pond water is an important thing that must be done every day. This is to make it easier if there are changes or anomalies, farmers can take steps as quickly as possible.

Not only observing the color of pond water which is suitable for vannamei shrimp but there are also other indicators that must be monitored regularly every day. The following are the indicators:

1. Pond Water Color

As previously explained, the color of pond water indicates the quality of the water in it. The best color for vannamei shrimp pond is dark green without slime and light brown.

2. Pond Water Brightness

Good pond water brightness ranges from 25-60 cm. Meanwhile, the brightness number is below it. In that case, it is difficult for sunlight to penetrate the water, resulting in low water temperatures and the photosynthesis process not running optimally.

3. Pond Water pH

pH is the level of acidity of water that is measured physically and greatly affects the organisms that live in it. The ideal pond water pH ranges from 7.5-8.5. Changes in pH in vannamei shrimp ponds can cause shrimp to become stressed. Therefore, it is vital to keep the pH ideal.

4. Dissolved Oxygen

Dissolved oxygen, also known as DO, supports shrimp in the respiration process. This indicator also dramatically affects the growth of shrimp. Usually, to keep the DO stable, aerators are used according to the needs of each pond.

5. Water Temperature

The ideal pond water temperature ranges from 28-31 degrees Celsius. Farmers must maintain this perfect temperature to remain stable every day. This is because temperatures that decrease or increase drastically can cause the death of shrimp in large enough numbers.

6. Pond Water Alkalinity

A good level of alkalinity concentration for vannamei shrimp is 130-180 ppm. This alkalinity is the ability of water to neutralize additional acids without lowering the pH level of the water. Alkalinity indicators need to be monitored regularly because they directly affect the growth of shrimp and supporting microorganisms in pond ponds.

7. Water Salinity

The ideal pond water salinity ranges from 15-25 ppt. This salinity condition must be maintained to remain stable. This is because less salinity can result in less optimal shrimp growth. In addition, too fast fluctuations in salinity can also cause stress in shrimp and can trigger death.

Vannamei Shrimp Salinity and How to Control Its Stability during Cultivation

Vannamei shrimp salinity is an essential factor that must be considered when cultivation occurs. This is because salinity significantly impacts the health and growth of shrimp in ponds.

Vannamei shrimp, also known as white leg shrimp, are shrimp native to the Pacific Ocean that can tolerate various levels of salinity. However, the optimal salinity for vannamei shrimp is around 15-25 ppt with a pH level of 7.5-8.5.

If the water salinity is too high, vannamei shrimp can become stressed, and their growth will be less than optimal. On the other hand, if the salinity is too low, the shrimp cannot absorb enough oxygen resulting in respiratory problems.

So, for those who want to know more about vannamei shrimp salinity and how to control its stability during cultivation, check out the following article.

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

What is Water Salinity?

Water salinity refers to the amount of salt content in seawater, river water, or lake water which is calculated in ‰ (thousand/ppt). For vannamei shrimp, the optimal range of water salinity is around 15-25 ppt which allows the shrimp to absorb sufficient oxygen.

The salinity of vannamei shrimp must be monitored and tested regularly during cultivation. This aims to ensure that the salinity rate remains within the optimal and stable range.

If the salinity is too high, it can be reduced by adding fresh water to the system. Meanwhile, if the salinity is too low, it can be increased by adding a brine or salt mixture to fresh water.

Also Read: This is The Best Water Color for Vannamei Shrimp Pond

How to Control the Stability of Pond Water Salinity

Maintaining the stability of vannamei shrimp salinity during cultivation is very important. This is because the saltiness of the water directly affects the health and growth of shrimp.

For vannamei shrimp, the ideal water salinity is around 15-25 per thousand (ppt). At this salinity level, vannamei shrimp can absorb sufficient oxygen through their gills and are less likely to experience stress or disease.

To ensure that the salinity of the water is at the proper level, farmers need to test and monitor the water regularly using a salinity meter or hydrometer.

Usually, the best time to measure salinity is in the morning and evening. Because, at these times, the salinity can change due to the influence of water evaporation by sunlight. In addition, when it rains, there is usually a decrease in the salinity due to the volume of rainwater entering the pond.

Not only that, but farmers also have to keep the water clean and have a stable dissolved oxygen content. This is so that the growth and health of the shrimp are appropriately maintained.

If the vannamei shrimp salinity is too high during the measurement, the farmer can anticipate this by adding fresh water up to the initial height before evaporation occurs.

Meanwhile, farmers can dispose of fresh water on the pond’s surface if the water salinity is low. This is because freshwater has a lower density than salt water, so freshwater is on the pond’s surface.

By following these guidelines and properly managing water salinity, shrimp farmers can help ensure the health and growth of their vannamei shrimp, leading to higher yields and profits.

The Importance of Wastewater Treatment Plant (WWTP) for Shrimp Ponds

The importance of WWTP or Wastewater Treatment Plant has recently become a concern in every shrimp culture. This is because WWTP functions to manage waste generated from ponds.

The waste generated from vannamei shrimp farming usually consists of water mixed with feces, leftover feed, and other organic debris. These wastes can cause water to become cloudy and polluted if not appropriately managed.

Therefore, let’s get to know more deeply the importance of WWTP for the following shrimp ponds.

As long as vannamei shrimp farming takes place, pond water can produce waste consisting of shrimp droppings, leftover feed, and organisms often found settling at the bottom of the pond.

This wastewater can become a pollutant that harms the environment. However, pollutant levels depend on the length of rearing, the stocking density of vannamei shrimp, the substrate in the pond, and the construction of the pond.

If measured by water quality parameters such as biological oxygen demand (BOD), total suspended solids (TSS), entire organic matter, turbidity, total nitrogen (TN), and total phosphate (TP), wastewater will show exceptionally high levels.

Wastewater Treatment Process

Treating vannamei shrimp pond wastewater usually considers two things: effective processing and efficiency in reducing pollutant levels. At the same time, the processing techniques are divided into three types, namely mechanical, chemical, and biological processing methods.

Meanwhile, the importance of WWTP in shrimp ponds is used to avoid chemical waste processing. This is because processing with chemical techniques can harm the environment. After all, it can threaten food safety.

Mechanical waste treatment is carried out through a settling process to reduce TSS. The settling process can be carried out in several ways, such as by filtering or slowing down the water flow’s speed so that it does not exceed 20 m/s.

While wastewater treatment with biological processes is carried out under aerobic, anaerobic conditions, or a combination of both. Aerobic conditions are usually used for wastewater treatment with a BOD load that is not too large, while anaerobic biological processes are used for wastewater treatment with a high BOD.

Biological wastewater treatment is divided into three: suspended culture, biological processes with attached cultures, and processing with lagoon or pond systems.

Stages of Waste Treatment Through the WWTP System

The WWTP system helps farmers to treat pond water waste, so it is safe for the environment. The waste treatment process through the WWTP system usually consists of three stages:

1. Filtering

Waste from the vannamei shrimp farming process is first filtered through filter media such as cloth or biological media such as rock which can capture large particles such as dirt and leftover feed.

2. Biological Approach

After the waste is filtered, the waste is treated biologically using bacteria that can decompose organic waste into gas and water.

3. Clearing

After the waste is decomposed into gas and water, the water is filtered to remove any remaining particles. After that, the water can be reused for vannamei shrimp cultivation or discharged into the environment with a level of turbidity per the standards applied.

Using the WWTP system, the waste generated from vannamei shrimp farming can be appropriately managed so that it does not cause water pollution and damage the environment.

Factors Influencing WWTP Design

The design of the Wastewater Treatment Plant (WWTP) is influenced by several factors, including:

1. Waste Water Volume

WWTP design is influenced by the volume of wastewater produced because the volume is used to determine the capacity of wastewater treatment units. If the volume of sewage is large, the capacity of the treatment unit must be made large to accommodate it.

2. Wastewater Flow Rate

The velocity of wastewater flow dramatically affects the sedimentation process. The sedimentation process can be optimal if the water flow rate is < 20 m/sec.

3. Availability of Land and Space

The amount of land or space for a wastewater treatment plant is determined by several factors: the volume of wastewater that must be treated and the level and variety of wastewater pollution materials.

4. Cost Availability

Construction of ponds, operations, and maintenance of WWTP requires a lot of money, and the amount depends on the technology and equipment used.

1. Choose The Right Farm Location

The selection of a pond location is the first thing that must be considered when starting a shrimp pond business. It aims to get a suitable and precise location according to the criteria. A good pond location must pay attention to the topography level, the soil’s content, and the water supply’s adequacy.

2. Make Sure to Choose Ideal Shrimp Fry

The fry is shrimp seeds. This term refers to the chicks that have entered the post-larva stage and are ready to be stocked into the pond. The ideal fry has a big impact on the success of shrimp farming.

Therefore, choose and prepare the best fry for those just starting a shrimp farming business. The ideal fry criteria include disease free and resistant.

3. Prepare Farm Equipment and Tools

When starting a shrimp farming business, you don’t only need pond land and fry. But there are a series of tools to support the sustainability of your cultivation. Starting from anco, waterwheels, and pumps, to laboratory equipment.

Each pond must have its equipment and should not be used interchangeably. Because this is to avoid confusion about the results of the examination of the condition of each pond pond.

4. Ensure the Right Feeding Management

Feeding in shrimp farming must be done appropriately and efficiently in terms of time and amount. This is because most of the capital in shrimp farming is spent on feeding.

Feeding time in the shrimp farming business is usually regulated in feed management, whose quantity has been adjusted and calculated based on the age of the shrimp. In addition, the feeding area (feeding area), feeding level (feeding level), and frequency of feeding (feeding frequency) are also considered in

5. Do Regular Water Quality Observations

Before starting a shrimp farming business, the last thing that must be considered is observing water quality. By observing water quality, each farm personnel can find out if changes or fluctuations in parameters may harm shrimp development.

Usually, water quality observations are carried out physically, chemically, and biologically. Measurements of physical parameters can be directly carried out when in ponds. Meanwhile, chemical and biological parameters must be carried out in the laboratory.

Vannamei Shrimp Feed Management Tips for Your Anti-Loss Cultivation!

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.
