Shrimp farmers should be aware of how to make liquid organic fertilizer. Fertilizers help boost plankton growth, which is beneficial for cultivation. Making organic fertilizer is also cheaper than purchasing inorganic ones. Organic fertilizers can be made by mixing organic materials with mineral nutrients. Learn 2 ways to make liquid organic fertilizer for shrimp farms in this article!

<ToC />

## How to Make Simple Liquid Organic Fertilizer
The first way to make liquid organic [fertilizer](https://jala.tech/blog/cultivation-tips/fertilizers-for-growing-planktons-in-shrimp-farms) can be done with fewer ingredients. Hence, it is suitable for farmers who want to make fertilizers at less cost. Here are the ingredients:
- 1 kg of bran
- 100 g of ZA fertilizer
- 4 ml of MSG 3
- 100 ml of aquaculture EM4  
- 3 tbsp of instant yeast
- 100 ml of molasses
- Sterilized water as needed

Follow these steps to make the simple liquid organic fertilizer:
1. Mix all the ingredients in a covered container.
2. Let it sit for 48 hours.
3. After 48 hours, filter the liquid fertilizer and dispose the residue. The liquid organic fertilizer is ready to be used. 

The dosage above is suitable for one-time stocking. Adjust the amount of ingredients based on the desired usage.

## How to Make Enhanced Liquid Organic Fertilizer
Aside from the first way, you can also make liquid organic fertilizer with this second method. This method requires more ingredients and is suitable for those of you who want to add more nutrients into your pond. Here are the ingredients you need to prepare:
- 500 grams of high-protein shrimp pellets
- 500 grams of mung bean sprouts
- 500 grams of pineapple with skin
- 500 grams of banana stems, trunks, and fruit
- 25 grams of tapai yeast
- 250 grams of fish meal
- 2 liters of coconut water
- 1.2 liters of rice wash water
- 250 ml of aquaculture EM4 
- 300 ml of molasses

Follow these steps to make enhanced liquid organic fertilizer:
1. Blend pellets, sprouts, pineapple, bananas, and fish meal in a blender. Add water if needed for a smoother blending process.
2. Transfer the blended mixture to a gallon or container.
3. Add coconut water, rice wash water, and plain water until the total liquid reaches 10 liters.
4. Add molasses and yeast, then stir until dissolved.
5. Add EM4, stir, and cover the container.
6. Let it ferment anaerobically for 3 days.
7. The liquid organic fertilizer is ready to be applied.

## How to Apply Liquid Organic Fertilizer in the Pond
Liquid organic fertilizers help in supporting [plankton growth](https://jala.tech/blog/cultivation-tips/tips-on-growing-the-plankton-in-shrimp-farm), which functions as a natural food source and a light buffer in shrimp ponds. In addition, the use of EM4 in the fertilizer adds probiotics or beneficial microorganisms to the pond, helping to reduce the population of pathogenic bacteria and improve water quality.

Since liquid fertilizers quickly release their nutrient content, shrimp farmers need to apply it regularly at certain intervals and monitor water clarity as an indicator of adequate plankton population in the pond.

Apply the liquid organic fertilizer once a week in the morning with a dosage gradually increased, starting from 2 liters/ha in the first month, 4 liters/ha in the second month, and 8 liters/ha in the third month. Dilute the measured fertilizer with water from the tank and pour it into the pond. Store the remaining fertilizer in a shaded place away from direct sunlight. Stop applying the fertilizer when the pond water reaches a sufficiently brownish green color.

## Conclusion
Liquid organic fertilizers can be made by mixing organic materials and mineral nutrients. This type of fertilizer supports plankton growth in the farm.

When applying fertilizers in pond water, it is important to keep monitoring water quality. For a more convenient monitoring of water quality and overall farm condition, you can use [JALA App](https://jala.tech/app). JALA App is a shrimp farm management application that helps you record and analyze cultivation conditions to take the best step in your farm.

2 Ways to Make Liquid Organic Fertilizer for Shrimp Farms 

The benefit of TSP fertilizer for shrimp farms are gaining attention among shrimp farmers. This type of fertilizer is known to promote the growth of plankton in shrimp farms.

TSP (triple superphosphate) fertilizer is an inorganic or [mineral](https://jala.tech/blog/cultivation-tips/minerals-for-vannamei-shrimp) fertilizer rich in phosphorus. This fertilizer is commonly used in agriculture to cultivate and fertilize plants.

Besides agriculture, TSP fertilizer can be utilized in aquaculture, including shrimp farming. Some farmers utilized it as a treatment material. The benefit of TSP fertilizer for shrimp farms will be discussed in detail below.

<ToC />

## The Benefit of TSP Fertilizer for Shrimp Farms
TSP fertilizer can supply primary nutrients to the pond, including phosphorus. Phosphorus from TSP fertilizer is one of the essential nutrients required for [plankton growth](https://jala.tech/blog/cultivation-tips/tips-on-growing-the-plankton-in-shrimp-farm) in shrimp farms.

Plankton is a natural feed source for shrimp, particularly in their early phases of growth after being stocked. If the demand for this natural feed is met, shrimp will be able to grow optimally. 

In addition, plankton also contribute to the photosynthesis process to produce oxygen in the pond throughout the day. If the oxygen levels in the water are sufficient, the shrimp's respiration and metabolism processes will run more smoothly. This will minimize the slow growth case of shrimp.

## Using TSP Fertilizer for Shrimp Farms
You can apply TSP fertilizer after the pond drying stage. If it has dried, proceed with the water refilling stage. During this stage, mix TSP and urea fertilizer in one sack and hang it under the feeding tray bridge. The fertilizer will disperse itself into the pond.

## Conclusion
The benefit of TSP fertilizer for shrimp farms is to help in [growing plankton](https://jala.tech/blog/cultivation-tips/fertilizers-for-growing-planktons-in-shrimp-farms). Plankton requires sufficient phosphorus to grow properly, and TSP fertilizer can meet this demand.

You can apply TSP fertilizer as a treatment after draining the pond. Keep track of the results by recording each treatment in [JALA App](https://jala.tech/app), the shrimp farm management application.

Not only does it facilitate treatment recording, but JALA App is also #HeretoHelp you to

The Benefit of TSP Fertilizer for Shrimp Farms

Maintaining good biosecurity for shrimp farmers isn’t just an operational task; it’s a critical measure to protect the health of their stock, preserve productivity, and safeguard investment. Implementing highly accurate pathogen testing can make all the difference in mitigating risk and ensuring the long-term success of shrimp farms. 

<ToC />

## The Risks of Inadequate Testing in Quarantine Procedures
Without rigorous pathogen testing, shrimp farms (and production systems) expose themselves to significant risks. Shrimp pathogens — including viruses, bacteria and microsporidia — can spread rapidly within and between farms, leading to costly outbreaks that can devastate operations. Comprehensive early detection is particularly vital in the quarantine phase, where any pathogens present in new stock can be identified and the biosecurity risk managed before spreading further.

Steve Arce, Global Technical Manager for Shrimp BU at Hendrix Genetics, emphasizes that current mandatory testing requirements (while helpful) may not be enough given the evolving nature of pathogens and variations in testing standards between countries. He explain that,

 
>Each country is at different levels.


>The need is there to apply more rigorous application in terms of proper PCR techniques and understanding of the pathogens of concern.

This evolving landscape requires farms to think beyond compliance, prioritizing thorough testing to safeguard their biosecurity and ensure dangerous pathogens don’t slip through the cracks.

## Real-World Benefits of Comprehensive Testing
For Atlantic Shrimpers, a shrimp farming operation based in Nigeria, additional pathogen testing in quarantine has become standard practice. Project Manager Françoise Pironet shares that they encountered a pathogen, LSNV, in their stock despite the broodstock passing supplier-provided tests. Pironet also explain,

 
>Our suppliers test batches before shipment, but we use Genics Shrimp MultiPath as a second line of defence.

>Without it, we wouldn’t have detected LSNV in the batch of broodstock, which could have spread throughout our entire stock.

This additional layer of screening prevented a potentially damaging outbreak, saving Atlantic Shrimpers from significant financial and operational impacts. 

Genics Shrimp MultiPath allows farmers to act with confidence, protecting their investment, surrounding environments, and the integrity of local shrimp populations.

Similarly, on an isolated island farm in Seychelles, Islands Development Company’s Fisheries & Aquaculture Development Manager, Riaz Aumeeruddy, oversees strict testing protocols. 

>The accuracy and sensitivity of pathogen testing are of major importance for our farm - Aumeeruddy explains. 

The island’s isolation amplifies the importance of preventing any pathogens from entering the farm, as the spread to surrounding oceanic waters would jeopardize both the farm and the local ecosystem. By placing new shrimp larvae in quarantine until all pathogen tests return negative, Aumeeruddy and his team are implementing best-practice and doing everything they can to have a high-level of confidence to introduce only healthy stock to grow-out ponds.

>With Shrimp MultiPath, we are confident we are screening as comprehensively as possible.

## Going Above and Beyond: The Value of Highly Sensitive Testing
The experiences of Atlantic Shrimpers and Islands Development Company highlight a crucial point for shrimp farmers worldwide: going beyond standard testing requirements is an investment that protects the long-term viability of their farms. Routine pathogen screening that uses sensitive, accurate methods enables farms to detect even trace levels of pathogens. This level of scrutiny, often above and beyond what regulations require, provides essential security.

Steve Arce recommends a similar approach for the industry, particularly for quarantine testing. 

>Routine screening of all shrimp stocks with statistically significant sample sizes provides at least 98% confidence in health status. 

In his experience, adding these practices and employing Shrimp MultiPath alongside histopathology significantly reduces the risk of pathogens going undetected. By investing in testing practices that ensure pathogen detection at the earliest stage, farmers can stop potential outbreaks before they start, preserving farm productivity and profitability.

MultiPath testing provides qualitative and quantitative data, giving farmers a clear picture of the pathogen load in their stock. For shrimp farmers, this detailed insight translates to better decision-making and the ability to implement timely interventions, protecting both their stock and their investment.

As Pironet describes,
 
>Genics MultiPath testing doesn’t just identify pathogens but also allows us to develop the best strategy tailored to our needs.

>This service goes beyond basic testing and helps us make informed decisions that protect our operation.

## Reducing the Spread of Emerging Pathogens
The shrimp industry faces an ever-present challenge of emerging pathogens and changes in existing pathogen strains. 

As Arce points out,

>It’s not the pathogens we know of now that pose the greatest threat, but the yet-to-be-identified pathogens which should be considered and proactively addressed.

With the rapid movement of live shrimp stock across countries, farms are at constant risk of encountering new pathogens. A highly sensitive testing approach allows farms to screen comprehensively for known and emerging threats, protecting the health of their current stock while preventing the spread to other farms.

## Case for Best Practices in Pathogen Testing
For shrimp farmers, investing in highly accurate, sensitive pathogen testing isn’t just about protecting a single crop; it’s about preserving the entire operation and, ultimately, the future of their farm. 

By integrating MultiPath into their testing protocols, farms like Atlantic Shrimpers are able to detect pathogens like LSNV in imported broodstock, where other tests failed, minimizing the risk of outbreaks.

>The cost of Genics Shrimp MultiPath testing is worthwhile. Additional screening ensures that each batch that arrives is safe, significantly reducing the risk of a disease outbreak.

For isolated farms like Islands Development Company in Seychelles, additional testing supports the entire ecosystem in which they operate, ensuring that farms contribute to sustainable shrimp production rather than creating vulnerabilities.

Incorporating thorough, statistically significant testing in quarantine practices gives farmers confidence in their stock’s health, while also setting a high standard for biosecurity across the shrimp industry. 

In a world where pathogens are constantly evolving, the importance of sensitive and accurate testing before translocation or movement cannot be overstated.

In shrimp cultivation, ensuring the growth of planktons in pond water is an essential step that farmers should take to maintain water quality. One of the ways farmers can support plankton growth is by applying rice bran ferment. Rice bran fermentation can be done easily in just five steps. What are the steps of rice bran fermentation for shrimp farms? Learn more in this article.

<ToC />

## Benefits of Fermented Rice Bran 
Fermented rice bran has various benefits for shrimp farms, such as helping create an environment which supports the growth of planktons and beneficial bacteria for shrimp. Moreover, fermented rice bran also serves as an extra source of nutrients which is easily digestible for shrimp to speed up their growth rate and increase their immunity.

## How to Make Fermented Rice Bran for Shrimp Farms 
Here are the ingredients you need to make fermented rice bran, which can be used for farms with an area of 500 m²:
- 500 g of rice bran
- 5 ml of _Lactobacillus_ sp.
- 500 g of water (1:1 ratio with the rice bran)
- 2.5-5 mg of yeast

You can adjust the amount of each ingredient to your farm area.

Make fermented rice bran easily with these five steps:
1. Prepare a clean and hygienic container with a minimum capacity of 25 liters.
2. Pour water into the container.
3. Add all the ingredients and mix until they form an even mixture.
4. Close the container tightly to prevent air from entering.
5. Let it sit for 24 hours, and the fermented rice ban is ready to use.

## How to Apply Fermented Rice Bran in Shrimp Farms
Fermented rice bran has a distinct aroma which is similar to fermented cassava. If you detect a foul smell, discard the fermented rice bran as it may have been contaminated by harmful microbes that can poison the shrimp. Repeat the fermentation process and ensure the container is completely sealed to prevent contamination.

Apply the fermented rice bran in the pond three times a week in the afternoon or evening. Wait 5-7 days to observe changes in pond water color due to plankton growth. Stop applying rice bran once the water has reached a brownish green color.

## Conclusion
Fermented rice bran is one type of treatment in the farm for farmers who want to improve water quality by promoting plankton growth. Rice bran can be fermented with the _Lactobacillus_ bacteria and yeast in a sealed container for 24 hours and applied to ponds thrice a week until the pond water turns brownish green.

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.

## 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.

## The minimal size target of vannamei 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.

To assist you in monitoring the sampling results, [JALA App](https://jala.tech/app) is #HeretoHelp with the recording and analysis features of 40+ cultivation parameters. In addition to record sampling results, you can also record [water quality parameters](https://jala.tech/blog/cultivation-tips/four-important-physical-parameters-of-water-quality-in-shrimp-farms), feed, disease, shrimp mortality, harvest, and many more.

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:

### 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 Larva Udang Vaname.png](https://strapi.jala.tech/uploads/Post_Larva_Udang_Vaname_70ad575395.png)
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.

Vannamei Shrimp Life Cycle: From Eggs to Adult Shrimp

Shrimp cultivation is often considered [a promising business](https://jala.tech/blog/shrimp-industry/4-reasons-why-shrimp-farming-is-considered-promising), especially in Indonesia, a country with significant potential for cultivation due to its geographical location and climate. Among various types of shrimp, the ones commonly cultivated are freshwater shrimp.

Before starting a [shrimp farming business](https://jala.tech/blog/cultivation-tips/5-things-to-consider-before-starting-a-shrimp-farming-business), prospective farmers interested in exploring the shrimp cultivation industry need to get familiar with the various types of freshwater shrimp that are often cultivated in ponds in order to decide which type of shrimp to cultivate based on their characteristics.

## 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

Before starting cultivation, make sure to understand the characteristics of each shrimp type to choose the most suitable one for your business goals. Additionally, provide appropriate [treatment](https://jala.tech/blog/cultivation-tips/7-effective-treatments-in-shrimp-cultivation-management) in your farm according to the type of shrimp, ensuring that they grow well and can be sold at a profitable price.

5 Popular Types of Freshwater Shrimp that are Often Cultivated in Farms

<h2>Regencies where shrimp is the main commodity</h2>
<p style="text-align: justify;">Shrimp is one of the most in-demand fisheries commodities. According to data from the <a href="https://www.kkp.go.id/" target="_blank" rel="noopener noreferrer">Indonesian Ministry of Maritime Affairs and Fisheries</a>,&nbsp; shrimp is the largest export commodity in Indonesia compared to other fishery commodities. In 2020, its export volume reached 239.28 million kgs, with a value of US$ 2.04 billion.</p>
<p style="text-align: justify;">The rising demand for shrimp has prompted the growth of shrimp farming in numerous regions in Indonesia. As a result, the shrimp farming industry in Indonesia continues to expand. Over a ten-year period (2009-2019), the annual growth rate of vannamei <a href="https://jala.tech/blog/shrimp-industry/key-to-successful-cultivation-sustainable-shrimp-production" target="_blank" rel="noopener noreferrer">shrimp production</a> in Indonesia reached 2.4 percent.</p>
<p style="text-align: justify;">Shrimp farming business in Indonesia is spread in coastal areas. Some of them are:</p>
<h3>South Lampung, Lampung</h3>
<p style="text-align: justify;">Vannamei shrimp is one of the leading commodities in South Lampung. Despite being affected by the COVID-19 pandemic, the industry is gradually getting back on its feet&nbsp; This is shown by the rising market price of vannamei shrimp. Furthermore, the shrimp industry in South Lampung is being supported by the development of pilot ponds in an endeavor to restore the glory of the shrimp commodity in Lampung.</p>
<h3>Cirebon, West Java</h3>
<p style="text-align: justify;">Rebon shrimp is a popular commodity in Cirebon. However, in addition to rebon shrimp, people in Cirebon are also interested in vannamei shrimp farming because the risk of failure is lower. Cirebon's extensive water area helps to support vannamei shrimp farming.</p>
<h3>Situbondo, East Java</h3>
<p style="text-align: justify;">The majority of shrimp ponds in Situbondo Regency use an intensive cultivation system where the density of stock is high. This is one of the reasons behind the regency's high productivity per area of shrimp ponds. In terms of quality, shrimp cultivated in Situbondo are also relatively better because the sea water on the area's coast is calmer and less polluted by industrial pollutants.</p>
<h3>Jembrana, Bali</h3>
<p style="text-align: justify;">In contrast to the majority of Bali's other districts which prioritize tourism, Jembrana Regency prioritizes the fishery sector, particularly shrimp farming. Almost all of the farmers in the district cultivate in traditional or <a href="https://jala.tech/blog/cultivation-tips/extensive-pond-can-also-be-productive" target="_blank" rel="noopener noreferrer">extensive ponds</a>. Nonetheless, the shrimp industry actors and the local government continue working to boost its production.</p>
<h3>Lombok, West Nusa Tenggara</h3>
<p style="text-align: justify;">Aside from tourism, the fisheries sector, particularly shrimp farming, is significant to Lombok Island. Farmers in Lombok can produce more than 200 tons of Vannamei shrimp in a single harvest cycle. Shrimp farming on this island is primarily focused on meeting the country's need for shrimp.</p>
<p style="text-align: justify;">Shrimp farming in Indonesia's shrimp production areas should be maximized. Its productivity will undoubtedly increase if it runs optimally. To that aim, the Indonesian Ministry of Maritime Affairs and Fisheries has implemented a number of strategies to boost shrimp farming productivity in Indonesia. Two of these are projects for integrated shrimp farming and pond revitalization.</p>
<p style="text-align: justify;">In addition, <a href="https://app.jala.tech/register" target="_blank" rel="noopener noreferrer">digital technology</a> for shrimp farming must be implemented. Farmers will be more supported in running cultivation through the use of digital technology, and cultivation production is expected to increase. If these measures are effective, the Indonesian Ministry of Maritime Affairs and Fisheries'&nbsp;production target of 2 million tons by 2024 is not impossible to achieve.</p>
