JALA Strengthens Aquaculture Resilience in Indonesia 

In shrimp farming, saponin is often applied during the pond preparation stage before stocking post-larvae. Its main purpose is to eliminate unwanted wild fish, especially predators that may inhabit the pond. Saponin is a natural compound typically derived from plants such as tea seeds, papaya leaves, noni leaves or seeds, and sea bidara leaves, as well as from marine animals like sea cucumbers and certain types of bacteria.

This article explores the benefits of saponin and how to use it effectively and safely in shrimp farming.

<ToC />

## Benefits of Saponin in Shrimp Farming
Here are some key benefits of saponin that shrimp farmers can consider when using it in their ponds.

<LoginSection />
<HiddenContent />

- **Controls wild fish (predators).** Saponin can eliminate wild fish in the pond by damaging their gill respiratory system, causing osmotic stress, and eventually leading to death. This process helps clear the pond of natural shrimp predators before the culture cycle begins.
- **Acts as a detoxifying agent.** Certain saponin formulations contain antioxidants and immunostimulant compounds that help neutralize toxic residues, such as leftover organic pesticides, before stocking shrimp post-larvae.
- **Stimulates molting and plankton growth.** Saponin also contributes to synchronized [molting](https://jala.tech/blog/cultivation-tips/ways-to-speed-up-molting-in-vannamei-shrimp) in shrimp and supports [plankton](https://jala.tech/blog/cultivation-tips/effective-strategies-to-control-plankton-in-shrimp-farming-1) development. Shrimp shells and organic residues after molting act as natural fertilizers that promote plankton growth at the pond bottom.
- **Reduces wild plankton populations.** At specific concentrations, saponin can suppress uncontrolled growth of wild phytoplankton or zooplankton in the pond water.
- **Produces foam.** When saponin is applied and mixed with the water current generated by paddlewheels, it creates foam on the pond surface, a common visual effect of saponin use.

<MiddleAds />

## How to Use Saponin
Farmers should pay attention to several key points when applying saponin in shrimp ponds.
1. Timing of application: Saponin should be applied during the pond preparation phase, typically 5–7 days before stocking post-larvae, to ensure that its toxicity is completely neutralized before shrimp introduction.
2. Application procedure: Dissolve saponin in water before evenly spreading it throughout the pond, preferably with the help of paddlewheels for better distribution.
3. Dosage: The effective dosage of saponin for pest control ranges between 10-20 ppm before stocking, while for plankton reduction, it ranges between 5-10 ppm, depending on plankton monitoring results.

## Risks of Using Saponin
While saponin offers many benefits, improper use can cause negative effects on shrimp and pond conditions.
- Toxicity to shrimp. If applied at excessive concentrations or after shrimp have been stocked, saponin can cause stress or even mortality in shrimp.
- Side effects on water quality. Overuse of saponin may increase surface foam, which can interfere with oxygen exchange and reduce shrimp comfort if water flow and aeration are not well maintained.
- Residue buildup. Unbroken saponin residues or sludge may accumulate at the pond bottom, contributing to long-term water quality problems if not properly managed.

## Conclusion
Saponin provides numerous benefits in shrimp farming, from eliminating pests and improving water quality to supporting shrimp growth and resilience. However, it must be applied at the correct dosage and following proper procedures to ensure it remains safe for both shrimp and the pond environment. To make it easier to monitor pond water conditions from the preparation stage to the grow-out phase, use [Baruni](https://jala.tech/baruni), multi-parameter water quality monitoring. Get accurate, real-time results right in your hands and ensure your shrimp ponds stay in top condition!

Saponin is beneficial for eliminating pests in shrimp ponds, but the timing and dosage of its application must be carefully managed to avoid harming the shrimp.

Safe and Effective Use of Saponin in Shrimp Ponds

The demand for high production often pushes shrimp farmers to focus solely on achieving production targets, sometimes overlooking one crucial aspect, carrying capacity. Carrying capacity refers to the ecological suitability level that determines the maximum biomass or residual water load that a pond ecosystem can sustain. Ideally, it’s determined by the balance between the rate of waste generation from farming activities and the ecosystem’s ability to recycle or discharge that waste.

Carrying capacity of a shrimp pond is influenced by several factors, including pond size and depth, the aeration system (number and capacity of [paddlewheels](https://jala.tech/blog/cultivation-tips/the-importance-of-paddle-wheels-in-shrimp-farms)), and the availability of Dissolved Oxygen (DO). In addition, the type of feed and its management, wastewater handling, and overall water quality conditions play vital roles in maintaining ecosystem balance and supporting shrimp growth.

Read on to learn how to determine your pond’s carrying capacity accurately!

<ToC />

## Why Carrying Capacity Matters in Shrimp Farming
Farmers should pay attention to carrying capacity to keep their farming activities optimal, understanding this helps to:
- Ensure the number of shrimp does not exceed the pond’s environmental limits, keeping water quality stable.
- Prevent stress and disease, as shrimp living in optimal conditions have stronger immunity.
- Maximize production by maintaining appropriate stocking density for optimal growth and higher yields.
- Keep ponds productive across multiple farming cycles for long-term sustainability.

## How to Calculate Carrying Capacity
Carrying capacity can be calculated using simple to more advanced scientific approaches. Below are practical methods farmers can apply:

<LoginSection />
<HiddenContent />

### 1. Based on pond area and stocking density
**Basic formula:**
Carrying Capacity (shrimp count) = Pond area (m²) × ideal stocking density (shrimp/m²)
**Example:**
If the pond area is 1,000 m² and the ideal stocking density is 100 shrimp/m², then:
1,000 × 100 = 100,000 post-larvae.
Typically, the ideal stocking density ranges from 80-120 shrimp/m², depending on the farming system and aeration capacity.

### 2. Based on oxygen capacity and environmental support
Carrying capacity can also be estimated by comparing the shrimp’s total oxygen demand with the pond’s oxygen production capacity:
a. Calculate the shrimp’s daily oxygen requirement (based on biomass and oxygen consumption per gram of shrimp).
b. Measure the oxygen generated through plankton photosynthesis and aeration.
c. Adjust shrimp density so that oxygen demand never exceeds production capacity.

<MiddleAds />

## How to Increase Carrying Capacity
Farmers must ensure that farming activities do not exceed the pond’s environmental limits to maintain good shrimp growth rates. Increasing shrimp production can be achieved by improving the pond’s carrying capacity.
- Reduce waste generated per kilogram of shrimp by using high-quality feed.
- Minimize wastewater discharge into the environment.
- Distribute wastewater evenly and avoid reusing untreated water in ponds.
- Improve environmental resilience by planting mangroves around ponds.
- [Treat and recycle wastewater](https://jala.tech/blog/shrimp-industry/guide-shrimp-farm-wastewater-management) for reuse in production ponds.

However, it’s important to remember that carrying capacity should never be exceeded. Signs of overcapacity include slow shrimp growth or declining ADG, deteriorating water quality (low DO, unstable pH), and organic matter buildup at the pond bottom. Increased disease outbreaks and higher mortality rates are also strong indicators that the pond’s capacity limit has been surpassed.

## How to Reduce Pond Carrying Capacity Load
When the pond exceeds its carrying capacity, farmers can take several actions to ease the load:
- Conduct [partial harvests](https://jala.tech/blog/cultivation-tips/shrimp-partial-harvest) when shrimp biomass surpasses the limit.
- Adjust post-larvae stocking density according to pond capacity.
- Feed according to actual shrimp needs and avoid overfeeding to prevent organic waste buildup (feed residue and feces).
- Add or upgrade paddlewheels/aerators to increase DO levels.
- Perform gradual water exchange (10–20%) to reduce waste concentration and stabilize water quality parameters.
- Regularly siphon sludge and feed residues from the pond bottom to prevent excessive organic accumulation.

## Conclusion
Understanding and calculating the carrying capacity of shrimp ponds is essential for achieving productive and sustainable farming. By determining carrying capacity accurately, farmers can optimize stocking density, maintain environmental quality, and reduce the risk of farming failure.

How to Determine the Ideal Carrying Capacity in Shrimp Farming

Vannamei shrimp has become one of the most promising aquaculture commodities in Indonesia. However, feed costs which account for 60-70% of total operational expenses, often pose a major challenge for farmers. Inaccurate feeding can lead to waste and reduced farming efficiency. To address this, the index method offers a practical solution after the [blind feeding](https://jala.tech/id/blog/tips-budidaya/mengenal-dua-trik-manajemen-pakan-blind-feeding-dan-puasa) stage, helping farmers adjust [feed amounts](https://jala.tech/blog/cultivation-tips/effective-feeding-practices-for-shrimp) based on shrimp needs and pond conditions to reduce costs and maintain productivity.

Let’s explore how to calculate feed using the index method in detail!

<ToC />

## Understanding the Feed Index Method
The feed index method determines the amount of feed based on a specific percentage (index), calculated from the shrimp’s age [(Day of Culture/DoC)](https://jala.tech/blog/cultivation-tips/shrimp-doc-is), total number of stocked shrimp, and target daily growth [(ADG)](https://jala.tech/blog/cultivation-tips/what-is-adg). This method is generally applied from DoC 30 until harvest, with index values typically set at 1.5-2 times the target ADG.

<LoginSection />
<HiddenContent />

## Formula for Feed Index Calculation
![Screenshot 2025-10-08 133224.png](https://strapi.jala.tech/uploads/Screenshot_2025_10_08_133224_f0be1d39f4.png)

Explanation:
- Index: 2 × target ADG. For example, if the target ADG is 0.15 gram, the index is 0.30.
- DoC: Shrimp age in days.
- Stocking density: Number of shrimp stocked in the pond.

Example calculation:
- DoC: 30 days
- Stocking density: 100,000 shrimp
- Target ADG: 0.17 gram, index 0.34

Then:
![Screenshot 2025-10-08 133442.png](https://strapi.jala.tech/uploads/Screenshot_2025_10_08_133442_53443f775d.png)

## Feed Index Table Example
Below is an example feed index table for a stocking density of 100,000 shrimp.
![Menghitung Pakan Sistem Indeks_EN.png](https://strapi.jala.tech/uploads/Menghitung_Pakan_Sistem_Indeks_EN_ccce34bfaf.png)

To achieve optimal results, several factors should be considered when using the feed index table. Generally, the index value is set at twice the target ADG to ensure sufficient feed for growth. It can be adjusted according to pond conditions and shrimp feeding behavior. During the early stage (DoC <30), farmers usually apply the blind feeding method, so the index method becomes effective after DoC 30. Regular [feeding trays checks](https://jala.tech/blog/cultivation-tips/daily-feed-evaluation-and-feed-management-with-feeding-trays) are also important to avoid overfeeding or underfeeding. For best results, combine the index method with the [Feeding Rate (FR)](https://jala.tech/blog/cultivation-tips/shrimp-feed-fr-table) method.

## Advantages of the Feed Index Method
Farmers can apply this method to make shrimp farming more effective and efficient.
- Simple and practical: No need for daily shrimp sampling, calculations are based on age and stocking density.
- Efficient: Minimizes risks of overfeeding or underfeeding, maintains water quality, and reduces production costs.
- Flexible: Index values can be adjusted according to growth targets and pond conditions.

<BottomAds />

## Conclusion
Calculating feed using the index method is a practical and efficient solution for shrimp farmers. With proper understanding, farmers can adjust feed quantities based on shrimp needs, optimize growth, and reduce production costs. However, it remains essential to monitor pond conditions and adjust feeding strategies regularly to maintain optimal farming performance. To make shrimp farming management even easier, farmers can use [JALA App](http://app.jala.tech) recording feature, which allows tracking of over 40 parameters, from water quality and daily feed to shrimp growth, harvest, treatments, mortality, and disease test results.

The index method helps farmers manage feed efficiently, reduce costs, and maintain optimal shrimp growth.

How to Calculate Shrimp Feed with the Index System

Algae are a type of plankton, and when they grow excessively in shrimp ponds, they can cause various serious problems, such as deteriorating water quality, reduced dissolved oxygen levels, and blocked sunlight penetration. Plankton overgrowth is generally caused by high nutrient content from feed or shrimp feces, poor aeration, high sunlight exposure, and the absence of natural predators or microbial competitors.

These conditions can lead to stress and even mortality in shrimp, making plankton control an essential step for healthy and productive shrimp farming. Let’s discuss why plankton control is a critical part of water quality management in shrimp aquaculture.

<ToC />

## Types of Plankton in Shrimp Ponds
Several types of plankton are commonly found in shrimp ponds, each showing different signs depending on pond conditions.
1. **Diatom (brown algae)**: Light brown in color, usually appearing in the early stages of culture. Their presence indicates stable and clean pond water with medium to high salinity.
2. **Green algae**: Ranges from dark to light green, indicating sufficient light and nutrients, with high Dissolved Oxygen (DO) during the day. They need to be monitored to avoid uncontrolled blooming.
3. **Blue-green algae (cyanobacteria)**: Bluish-green and slimy in texture, indicating water rich in organic waste and nutrients. These can produce toxins and lower water quality, so they require close attention.
4. **Euglenoid**: Greenish-red or brownish-green in color, indicating high organic matter and unstable water conditions.

## Signs of Plankton Blooming in Shrimp Ponds
When these signs appear, should not be ignored. Continuous monitoring and early action are necessary to prevent uncontrolled plankton growth:

<LoginSection />
<HiddenContent />

1. [Pond water](https://jala.tech/blog/cultivation-tips/hidden-threats-behind-murky-water-in-shrimp-ponds) turns very dense in color (dark green, bright green, or brownish), and water transparency drops drastically (usually <30 cm).
2. The water emits a strong or fishy odor, indicating organic buildup and high microbial activity.
3. Water pH fluctuates sharply (often above >8.5).
4. DO becomes unstable, typically high during the day but dropping sharply at night.
5. Shrimp show signs of stress, such as swimming at the surface in the early morning.

<MiddleAds />

## How to Control and Eliminate Plankton
To prevent unwanted effects of excessive plankton on shrimp, farmers should pay attention to the following.
1. [Feed appropriately](https://jala.tech/blog/cultivation-tips/effective-feeding-practices-for-shrimp) and avoid overfeeding.
2. Apply dolomite or quicklime according to water lab test results.
3. Replace 10-30% of pond water regularly with clean water.
4. Apply Bacillus probiotics (1-3 ppm) in the morning to break down waste.
5. Use copper sulfate with caution, adjusting the dosage and timing carefully.

## Daily Practices to Prevent Plankton Blooming
Farmers should develop these daily habits to monitor plankton conditions in the pond.
1. Check pH and DO every morning and evening to ensure no extreme fluctuations occur.
2. Observe the water’s color and odor visually to detect sudden changes caused by dominant plankton. 
4. Perform pond bottom siphoning regularly to reduce organic deposits that serve as plankton nutrients.
5. Evaluate daily feeding to ensure overfeeding does not occur, which can fuel plankton growth.
6. Measure water transparency using a secchi disk. If too turbid (<30 cm), take immediate action to reduce plankton.
7. Record all observations and measurements in daily logs to monitor trends and anticipate issues early. Use [JALA App](http://app.jala.tech) to make pond monitoring and record-keeping easier, so [plankton blooming](https://jala.tech/blog/cultivation-tips/ledakan-alga-di-tambak-udang) can be prevented at the earliest stage.

<BottomAds />

## Conclusion
The presence of plankton in shrimp pond ecosystems is often considered a problem that needs immediate attention. Plankton control must begin as soon as early signs appear, not after a major bloom occurs. Use pH, DO, temperature, and water transparency data to evaluate pond health daily. Ultimately, the key to sustainable shrimp farming lies in farmers’ ability to understand and manage the pond ecosystem as a whole.

Manage Your Farm More Efficiently: Enjoy the New JALA App Mobile, Now 4x Faster!

Shrimp size is an important parameter in cultivation and [harvest](https://jala.tech/blog/cultivation-tips/what-are-6-important-steps-of-shrimp-harvesting-process). Within one cycle, farmers usually aim for a specific size of shrimp, hence it is essential for you to know how to calculate shrimp size.

By understanding how to calculate shrimp size and knowing the exact numbers, you will be able to plan feed management better and determine the optimal price at harvest. You can save money on feed and sell your shrimp at best prices.

However, before figuring out how to calculate shrimp size, you have to understand what shrimp size is. Check out the discussion below.

<ToC />

<LoginSection />
<HiddenContent />

## What is Shrimp Size?
Shrimp size is closely related to the amount of shrimp and becomes a benchmark for profits in one cycle. Here’s the short explanation:

### An indicator of the amount of shrimp in 1 kilogram
A shrimp's size is determined by counting how many shrimp there are in every one kilogram. For instance, if you find a size 50 shrimp, it means there are 50 shrimp per one kilogram. The smaller the shrimp size number, the heavier and bigger the shrimp.

### Benchmark for selling prices
Shrimp size becomes a benchmark for selling prices to suppliers and an estimate of the future profits. Therefore, the smaller the shrimp size number, the higher the selling price and vice versa. For example, size 50 shrimp has a higher price than size 100 shrimp.

Farmers usually aim for a minimum size of 100 during the first partial harvest. Size 100 shrimp already has a solid economic value and the demand for it is quite high. In addition to size 100, the demand for size 90 to size 50 shrimp on both domestic and export markets is high as well.

## How to Calculate Vannamei Shrimp Size?
Once you understand what shrimp size is, you also need to understand how to calculate vannamei shrimp size. Apart from being calculated at harvest, vannamei shrimp size can also be calculated on a certain Day of Culture (DoC) through [sampling](https://jala.tech/blog/cultivation-tips/does-weekly-sampling-really-cause-losses-in-shrimp-farms).

Sampling is the activity of monitoring shrimp condition through multiple samples in feeding trays or nets. This activity is conducted periodically to determine the size, growth rate, Average Body Weight (ABW), and [Average Daily Gain (ADG)](https://jala.tech/blog/cultivation-tips/what-is-adg) of the shrimp from time to time. From the sampling results, farmers can also identify potential disease symptoms.

During sampling, you can use the following formula for calculating shrimp size:
![How to Calculate Shrimp Size.png](https://strapi.jala.tech/uploads/How_to_Calculate_Shrimp_Size_014209b2b0.png)

For example, a farmer conducted sampling on DoC of 56 days and found that the ABW of his shrimp sample was 10.47 grams. The farmer wanted to know the shrimp size, hence he did the following calculations:

Size = 1,000 grams / 10.47 grams = 95,5

From the calculation above, the shrimp size obtained is 95.5 shrimp/kg.

## Conclusion
In vannamei shrimp farming, size is 
- A measurement based on the amount of shrimp in every one kilogram
- One of the benchmarks for selling prices

Vannamei shrimp size calculation is done by dividing 1,000 grams by ABW. This calculation can be conducted both at harvest and at periodical sampling.

How to Calculate Vannamei Shrimp Size: Here's the Complete Explanation!

The vannamei shrimp life cycle consists of several stages, starting from eggs to finally becoming adult shrimp. Every developmental stage has different characteristics.

It is important to understand the life cycle of vannamei shrimp larvae to provide them with appropriate treatment. By understanding the life cycle of vannamei shrimp, you can identify their needs and adjust their surroundings.

What are the stages of vannamei shrimp life cycle and how should the larvae be treated? Read more in this article.

## What is the Life Cycle of Vannamei Shrimp?
The life cycle of vannamei shrimp begins with spawning between male and female shrimp. Female shrimp that have reached maturity or have reached 7-8 months and have an orange color on their backs can become broodstock. 

The female shrimp will release pheromones that stimulate male shrimp. After that, the mating process occurs. Later, the mating process between the male and female shrimp produces eggs which will be laid by the female shrimp.

About 4-5 hours later, female shrimp or now broodstock lay eggs. These eggs are pre-larvae which will later develop into cultivated vannamei shrimp.

Furthermore, read the following explanation about stages of shrimp life cycle:

<MiddleAds />

### 1. Eggs
A broodstock is usually capable of delivering 500,000-1,000,000 eggs each time it lays eggs. These eggs are kept apart from their broodstock in a different pond.

It takes 12-16 hours for the eggs to eventually hatch into microscopic larvae (naupli).

### 2. Naupli
Naupli or nauplius is the initial stage of development of vannamei shrimp larvae. At this stage, shrimp larvae at this stage have food reserves such as egg yolk stored in their bodies, hence they do not need artificial feed intake yet.

Throughout the naupli stage, the larvae undergoes six changes of form, namely Nauplius I, Nauplius II, Nauplius III, Nauplius IV, Nauplius V, and Nauplius VI.

![Naupli Udang Vaname.png](https://strapi.jala.tech/uploads/Naupli_Udang_Vaname_2168b28ce1.png)
Naupli (Wyban and Sweeney, 1991 in Nuraini, 2021)

### 3. Zoea
Naupli will grow into zoea or 1.05–3.30 mm shrimp larvae. At this stage, zoea undergo three changes of form, namely Zoea I, Zoea II, and Zoea III, and can be fed natural feed. This stage lasts for 3-4 days.

![Zoea Udang Vaname.png](https://strapi.jala.tech/uploads/Zoea_Udang_Vaname_20ccc25218.png)
Zoea (Wyban and Sweeney, 1991 in Nuraini, 2021)

### 4. Mysis
At the mysis stage, the larvae start to resemble shrimp because they have a fan-shaped tail. These larvae have the characteristic of moving backwards and bending their bodies (Azizah, 2018). 

Similar to zoea, mysis will undergo three changes in form, namely Mysis I, Mysis II, and Mysis III.

![Mysis Udang Vaname.png](https://strapi.jala.tech/uploads/Mysis_Udang_Vaname_fc974ca77e.png)
Mysis (Wyban and Sweeney, 1991 in Nuraini, 2021)

### 5. Post Larvae
The count used at this stage uses days, for example if the post larvae are 1 day old, they are PL1. Apart from that, shrimp in the post-larvae stage have started to actively move around.

Post larvae are usually raised until PL11-PL12. At this stage, the post-larvae is known as [shrimp fry](https://jala.tech/blog/cultivation-tips/the-strategy-to-choose-the-right-shrimp-fry) which are resistant to rearing conditions and are ready to be stocked in ponds.

Post Larvae (Wyban and Sweeney, 1991 in Nuraini, 2021)

### 6. Juvenile
Juvenile is the next stage of the shrimp life cycle following post larvae. At this stage, the shape of the shrimp already resembles adult shrimp. 

However, this stage is considered a vulnerable period in the shrimp life cycle because shrimp require a habitat with the right amount of feed and environmental conditions (Putri, Nitisupardjo, & Hendrarto, 2014). At this stage, the shrimp are transported from the hatchery to the farm for cultivation.

### 7. Young Shrimp
After 80-90 days from the juvenile stage, the shrimp will grow to be young shrimp. Its weight depends on the [cultivation system in the farm](https://jala.tech/blog/cultivation-tips/shrimp-farm-type), ranging from extensive to supra-intensive.

### 8. Adult Shrimp
About 25-30 days later, the young shrimp grow to be adult shrimp, and this is the final stage of the shrimp life cycle. 

Shrimp can be said to be adult starting 4 months after the juvenile phase. In this stage, the shrimp are ready to be harvested because they already reach enough economic value.

## Tips for Rearing Shrimp Larvae
Vannamei shrimp larvae require the proper treatment during their life cycle to ensure the best potential growth into shrimp. Here are some measures that need to be taken to rear vannamei shrimp larvae:

### 1. Maintain Water Quality

Water is a crucial factor since it is the habitat where shrimp larvae grow. Therefore, make sure that the water quality parameters in the rearing pond, such as pH, temperature, [salinity](https://jala.tech/blog/cultivation-tips/change-of-salinity-level-shrimp-ponds), and dissolved oxygen are in ideal conditions.

It is best to measure [water quality parameters](https://jala.tech/baruno) every day and record developments over time. These records can provide insights to help you take action in cultivation.

### 2. Manage Feed Properly
During the rearing period, shrimp larvae consume natural feed such as phytoplankton and zooplankton, especially since the zoea stage. However, if necessary, the hatchery will also provide artificial feed based on the nutritional needs of each larvae stage.

Shrimp larvae are fed 4-6 times a day in the [hatchery](https://jala.tech/blog/shrimp-industry/the-crucial-sector-in-shrimp-industry-hatchery). As the age of the shrimp larvae adds, the size of the feed and the dose given will increase. This is because the nutritional needs of shrimp larvae are increasing.

### 3. Prevent Diseases
[Shrimp disease](https://jala.tech/blog/shrimp-diseases/5-effective-ways-to-prevent-vannamei-shrimp-diseases) must also be paid attention to during the rearing period. Zoea Syndrome is one disease that often attacks shrimp larvae and is characterized by the larvae's unwillingness to eat since the Zoea I stage.

To prevent the spread of disease, it is best to separate the spawning tanks from the larvae rearing tanks. Additionally, maintain the sterility of the rearing area by, for example, making sure the person that helps with spawning them has received disinfection.

## Conclusion
The vannamei shrimp life cycle consists of 8 stages, namely
1. Eggs
2. Naupli
3. Zoea
4. Mysis
5. Post Larvae
6. Juvenile
7. Young Shrimp
8. Adult Shrimp

Once you understand the life cycle, make sure the hatchery where you get your shrimp fry implements the proper measures for rearing vannamei shrimp larvae. An SPF or SPR certificate is also required to minimize the risk of disease attacks and improve [the quality of the shrimp](https://jala.tech/blog/cultivation-tips/successful-tips-in-maintaining-shrimp-quality) itself at harvest.

The next important thing is recording the daily conditions of cultivation. In addition to the development of the shrimp fry, other variables such as feed, disease, and water quality measures should also be recorded.

## Various Types of Freshwater Shrimp
There are several types of freshwater shrimp that are popularly cultivated in Indonesia, such as the giant freshwater prawn, monkey river prawn, and the red nose shrimp. Let's explore the characteristics of each shrimp type!

### 1. Giant Freshwater Prawn
Next is the giant freshwater prawn (_Macrobrachium rosenbergii_), which is commonly found in rivers and coastal estuaries in Sri Lanka, Indonesia, and China. With a large body size, reaching up to 30 cm, and sweet, juicy flesh, giant freshwater prawns have a slow growth rate, taking about 180 days to reach a high economic value.

![udang galah](https://strapi.jala.tech/uploads/udang_galah_4d67f2736d.png)

Giant freshwater prawns come in various colors such as green, blue, brown, and yellow, with a curved long rostrum and longer claws compared to their legs.

### 2. Monkey River Prawn
The monkey river prawn (_Macrobrachium lar_) is commonly found in the West Indo-Pacific region. This type of shrimp thrives in both saltwater and freshwater habitats. Still, it is one of the most common types of freshwater shrimp cultivated in farms, where cultivation approximately takes 110 days.

![udang lar](https://strapi.jala.tech/uploads/udang_lar_748af1cb3b.jpeg)

Monkey river prawns have a considerably large body, with lengths reaching up to 18 cm. They can withstand high salinity in water, and exhibit good resistance to diseases, contributing to high productivity.

### 3. Red Nose Shrimp
Another type of cultivated shrimp with high economic value is the red nose shrimp (_Caridina gracilirostris_). They can be found in various regions such as Japan, Fiji, Indonesia, and Madagascar, particularly in rivers and estuaries. 

![udang beras](https://strapi.jala.tech/uploads/udang_beras_1b3c12cfd4.jpeg)

These yellow-orange, slightly transparent shrimp are not only sold as food but also popular as aquarium decorations due to their attractive red rostrum. They also consume algae, which makes them beneficial for aquarium owners.

### 4. Freshwater Crayfish
Freshwater crayfish (_Astacoidea_) is another type of freshwater shrimp commonly cultivated in farms. This type of shrimp lives in swamps, lakes, and rivers of various continents. Due to its low stress level and disease susceptibility, as well as the ability to grow quickly, this type of freshwater shrimp can be cultivated easily in soil-based ponds. 

![lobster air tawar (sumber: pak tani digital)](https://strapi.jala.tech/uploads/lobster_air_tawar_26d04e85d6.jpeg)

Several kinds of popular freshwater crayfish for cultivation include the red claw crayfish, red swamp crayfish, which is smaller in size, and the common yabby, known for its high tolerance towards extreme weather conditions including drought.

### 5. Roshna Prawn
The final type of shrimp on the list is the roshna prawn (_Palaemon styliferus_). This type of shrimp is also commonly found in Indo-Pacific regions including Iraq, Bangladesh, and Hong Kong. These freshwater shrimp grow well in tropical areas.

Roshna prawns are pale yellow and slightly transparent with a cone-shaped head are popularly processed as ebi with a high market price which makes it attractive for farmers.

## Conclusion
Various types of freshwater shrimp that are popular for cultivation include:
- Giant freshwater prawn
- Monkey river prawn
- Red nose shrimp
- Slipper lobster
- Roshna prawn
