What Is MBW Term In Shrimp Farming and How To Calculate It?

In shrimp farming, there are many important terms that farmers must know, one of them is MBW or Mean Body Weight. The term MBW refers to the average weight of vannamei shrimp per head resulting from sampling in a certain period.

MBW term in shrimp farming plays an important role during the cultivation period. It is because MBW is also used to calculate various other aspects of growth in shrimp. For example, to calculate ADG (average daily growth) and biomass of the vannamei shrimp.

So, how to calculate the MBW of vannamei shrimp? Let’s get to know about it in this article!

If you have been in the aquaculture industry for a long time, especially shrimp farming, you might know there are many unique terms which generally abbreviated. Starting from ABW, MBW, FCR, SR, and many more.

The term MBW comes from the mean body weight, which means the average weight. In shrimp farming, MBW is the average weight of shrimp per head obtained from routine sampling during cultivation.

The purpose of doing this MBW calculation is to determine the condition and growth of shrimp. In addition, if certain diseases attack the shrimp, it can also be known from the sampling carried out regularly by looking at the anomalies of its growth.

In addition, if there is an anomaly in the growth of shrimp or even if the shrimp is infected with diseases, it can also be identified through abnormal MBW conditions as an early detection before further lab research is carried out.

How to Calculate MBW of Shrimp?

How to calculate the MBW of shrimp is quite easy to do; the first step is to take a random sampling of shrimp at several anchor points in the same pond map. The shrimp that were successfully taken were then weighed and counted.

After calculating each weight and number of shrimp in the sampling, you can use a special formula, namely by dividing the total weight of the shrimp by the total number of shrimp weighed.

Simply put, the shrimp MBW formula is as follows:

Isn’t it easy to calculate the MBW of shrimp? However, keep in mind that sampling must be done in the same place on each pond plot. This aims to obtain more accurate results in measuring the growth of shrimp.

How to Cultivate Vannamei Shrimp from Preparation to Harvest

Many people want to start vannamei shrimp cultivation but still need to figure out where to start. It is because shrimp cultivation can not be arbitrary. There are many preparations and things that you must consider before starting it.

Vannamei shrimp is a fishery commodity that has high economic value. Since it was first introduced to Indonesia, vannamei shrimp has become a prima donna among farmers.
This is because the shrimp, which has the Latin name Litopenaeus Vannamei, has excellent resistance to the environment and can adapt quickly. Not only that, market demand for vannamei shrimp also continues to increase.

Unsurprisingly, many people are interested in starting vannamei shrimp cultivation. Well, for those who want to begin vannamei shrimp farming. Check out the following ways in this article!

Cultivation Preparation Stage

1. Pond Preparation

In vannamei shrimp cultivation, the first thing you must do is the Preparation of the pond to form an ecosystem conducive to the maintenance of shrimp during one cultivation cycle.

During pond preparation, there are several things you must ensure:

The pond is clean, dry, and not leaking.
Adjustment of aeration and turbulence needs with production targets, configurations, energy availability, and cultivation systems.
Ensuring ponds are free from potential remnants of microorganisms that can harm aquaculture activities, such as bacteria, viruses, etc.

2. Preparation of Farm and Laboratory Equipment

Each pond must have its equipment and may be used differently from other ponds. Both tools in the field, such as siphon hoses, Secchi disks, scoops, wall mounts, buckets, and water samplers, and laboratory equipment, such as water quality checkers, pH meters, and DO meters.

Therefore, the farmers must properly prepare every tool needed. Ensure all the equipment is complete and ready to use before the cultivation cycle begins.

3. Preparation of Human Resources

Not only pond preparation and equipment, competent and adequate human resources must also be prepared for vannamei shrimp cultivation. This is so that the cultivation of vannamei shrimp can run effectively and efficiently.

Make sure the number of human resources, expertise, and division of tasks for each person is carried out clearly. Good human resource preparation will result in neat pond data recording and more successful vannamei cultivation.

4. Pond Sterilization

Pond sterilization is included in the water preparation stage, which forms the essential ecosystem where the shrimp will grow and develop. Farmers must ensure that the combination of autotrophic and heterotrophic bacteria in the pond is balanced through this stage.

In addition, make sure no pathogens and other pests remain in the pond. Usually, sterilization is carried out by adding chlorine according to the rules and dosages that apply.

5. Microorganism Spreading

The final Preparation before cultivating vannamei shrimp is the spreading of microorganisms. These microorganisms can later become natural food for shrimp. But not only that, but microorganisms can also help absorb ammonia, produce oxygen, stabilize water temperature, and fight harmful bacteria.

Vannamei Shrimp Cultivation Procedures

1. Selection and Stocking of Seeds

cara budidaya udang vaname — Source: DELOS Documentation

The selection of fry is the key to success in vannamei cultivation. The ideal fry should be disease-free and disease resistant. In addition, several other criteria must be met, including body length > 10 mm, size variation < 1, intense color pigment, and active swimming spread.

Before the fry is stocked, acclimatization must first be carried out to accelerate the adaptation of the fry from the bag water medium to the pond water ecosystem. This stage also avoids stress on the fry and reduces the mortality rate when stocking.

2. Feeding Management

Intensive vannamei shrimp cultivation cannot be done without artificial feed. Therefore, farmers must prepare good feed management to maximize the cultivation that is carried out.

Shrimp feed management is a step to maximize the benefits of feed to support successful cultivation. Feed management is one of the most critical factors, especially about the capital spent. The more effective and efficient a person manages vannamei shrimp feed, the more efficient the money spent will be.

3. Do Routine Sampling

Routine sampling aims to determine the condition and development of shrimp during cultivation. Sampling is an important activity to see the growth of laws needed for evaluation, one of which is feeding.

Usually, sampling is carried out within a certain period to determine average body weight (ABW), growth (ADG), population estimation, survival rate (SR), biomass, and to observe the quality of the shrimp.

4. Water Quality Management

As long as vannamei shrimp cultivation takes place, farmers must implement good water quality management and continue to observe it. This is so that if there is a change or fluctuation in water quality parameters during cultivation, it will be easier for farmers to find out.

The water used for vannamei cultivation is seawater with a salinity level above 15 ppt which must be replaced every 60 days. While the parameters used to measure water quality include pH, DO, temperature, brightness, total ammonia nitrogen, NH3, total vibrio count, alkalinity, salinity, and the type and amount of plankton.

5. Vannamei Shrimp Treatment

Farmers must ensure that the shrimp are healthy and receive optimal nutritional intake during cultivation. Therefore various treatments, such as giving probiotics and vitamins, are necessary.

In addition, ponds must also be disinfected according to standards to inhibit the growth of microorganisms that are bad for the sustainability of cultivation.

6. Harvest

The last is the harvest stage, the process of picking the results from your vannamei cultivation. The harvest stage is divided into four: the overall harvest (total harvest), partial harvest (partial harvest), abnormal harvest, and emergency harvest.

A typical harvest occurs if the vannamei shrimp AW reaches more than 14 grams. Partial harvest is usually done when the pond capacity has reached the maximum limit. At the same time, abnormal and emergency harvests are carried out when certain things occur during cultivation, such as a high mortality rate.

Capital for Vannamei Shrimp Farming

Vannamei shrimp business is indeed promising, with fantastic profit potential, which has made it increasingly popular among the community. However, on the other hand, the capital required to start vannamei shrimp farming is not insignificant.

The amount of capital for vannamei shrimp farming depends on several factors. For example, the type of technology applied, whether it’s traditional, semi-intensive, intensive, or super-intensive.

The capital for vannamei shrimp farming can be divided into two categories: fixed capital and working capital.

Fixed capital refers to the initial capital invested when starting vannamei shrimp farming. The amount remains constant and is not affected by the fluctuation of operational costs. It includes expenses such as purchasing land (if you don’t already own it), equipment costs, and pond construction.

Working capital for vannamei shrimp farming is the ongoing expenses incurred during the farming process. These costs are fluctuating and depend on the operational needs of the farm. For example, costs for seedlings, fertilizers, feed, supplements, probiotics, and so on.

The amount of working capital can vary depending on your choice of high-quality fertilizers, feed, supplements, and probiotics. This will ultimately result in good harvest quality.

4 Types of Vannamei Shrimp Farms You Have to Know

A shrimp farm is an artificial pond that is used as a habitat for aquaculture activities, one of which is vannamei shrimp. Generally, the pond’s location is near a spring, for example, in a coastal area.

Most people think all vannamei shrimp farms are the same. However, this is not the case. There are several types of farms around us based on management techniques and density levels.

The types of farms include traditional, semi-intensive, intensive, and super-intensive farms. So, what are the characteristics of these farms? Find the full answer in this article!

Also Read: 7 Easy Ways to Cultivate Vanname Shrimp for Beginners

Types of Vannamei Shrimp Farms

1. Traditional Farm

The traditional vannamei shrimp farm is a type of farm that is made quite simply with a relatively low scale of shrimp seed stocking density. Usually, this type of farm does not require a pump and waterwheel. Meanwhile, the change of water depends on the tides.

The stocking density of traditional farm or extensive shrimp farming is <50 shrimp/m².

Due to its relatively low density, traditional shrimp farms have an easier level of maintenance when compared to other types of shrimp farms. Likewise, the risk of shrimp getting diseases is also smaller.

2. Semi-Intensive Farm

The second type of shrimp farm is the semi-intensive farm. This type of farm has a higher stocking density than traditional farms. Therefore, pumps and waterwheels are needed, which are adjusted to the size of the farm area to manage the water flow.

The stocking density of semi-intensive vannamei shrimp ponds is <100 shrimp/m².

As for the feed problem, since the seeds are sown, semi-intensive farms usually directly use artificial feed as the main source of nutrition for vaname shrimp. Along with water quality, this feed is the most important part that must be considered during cultivation.

3. Intensive Farm

An intensive farm is a shrimp farm with a fairly high stocking density of seeds. Usually, this type of farm requires complex design and layout calculations. Starting from the depth of the water, the need for a pump, and the need for a waterwheel, it must follow the needs.

The stocking density of intensive vannamei shrimp ponds is >100 shrimp/m².

When building an intensive farm, waste management also needs to be considered. The reason is that the higher the farms’ density level, the higher the waste generated during cultivation.

4. Super Intensive Farm

The last type of vannamei shrimp farm is the super intensive farm. As the name suggests, this type of farm requires more complex maintenance than other types of ponds. Many considerations must be prepared, ranging from supporting equipment to the impact of cultivation on the environment.

Super-intensive shrimp ponds are the same as intensive ponds, but the size and stocking density is more prominent. Usually, the stocking density of semi-intensive shrimp ponds is >200 shrimp/m².

Starting from the design, layout, need for pumps, number and type of waterwheels, as well as technology and management, must continue to be considered because the impact will be huge on the sustainability of cultivation and the environment where the farm is located.

After knowing the types of farms above, you must already know that we must consider many things before building a shrimp farm. Moreover, for semi-intensive, intensive, and super-intensive farms. Therefore, choosing the right location is very important to do.

The selection of farm locations aims to get the right and appropriate location so that the vannamei shrimp cultivation process can take place properly and the resulting harvest can be optimal.

The ideal farm location must have a good topography level to facilitate farm construction, contain clay-containing soil to hold water and build dams, and have sufficient water supply farms.

1. Water Quality Management

farm management yang baik — Source: DELOS Documentation

Water is the main component in aquaculture, so every aquaculture activity must have good water quality management as well. Then, how to have it? Well, the first thing that we have to do is monitor water quality. This could inform you if there is a change in water quality parameters during cultivation.

Water quality measurements are carried out physically, chemically, and biologically. Physical measurements can be carried out directly in each shrimp pond with parameters pH, temperature, DO, and water salinity.

Meanwhile, chemical and biological parameters can be carried out in the laboratory with parameters such as alkalinity, an abundance of plankton species, total bacteria, total vibrio, nitrite, nitrate, ammonia, phosphate, TOM, and total suspended solids.

In addition, the basic management of shrimp ponds must also be considered for the sustainability of aquaculture. The basic management of this pond includes the layout of the waterwheel, the activity of removing sludge, and the treatment of decomposing bacteria.

2. Vannamei Shrimp Feed Management

Vannamei shrimp feed management is another element that must be considered in shrimp farm management. The goal is to maximize feed use to support success and efficiency in shrimp cultivation.

Feed management is important in terms of the efficiency of capital spending during cultivation. This is because almost 60% of the capital is spent on feeding vannamei shrimp.

Several steps in feed management can be done through blind feeding, feeding after the first month, and using anco control.

Vannamei shrimp health management is carried out to observe any changes in the shrimp. These changes are usually signs of health problems and certain diseases that attack the shrimp.

Observations can be made first by looking at the characteristics of healthy shrimp, such as having active movements, complete and intact limbs, red and bright gills, full and unbroken gut contents, proportional body shape, bright skin color and clean, tail intact, and normal length growth.

If some anomalies or discrepancies appear during a health observation, be sure to immediately investigate and mitigate the disease.

4. Aquaculture Waste Management

Vannamei Shrimp Farm Management — Source: DELOS Documentation

As we know, aquaculture, including vannamei shrimp, produces organic waste that can pollute the surrounding waters. Therefore farmers need to have aquaculture waste management.

Farm waste is mostly in the form of easily degraded organic waste. These wastes come from feed residues, fermented materials, shrimp manure, and other organisms in the pond.

The management of vannamei shrimp culture waste can be carried out by being disposed of or cleaned through a siphon channel, decomposed with probiotics, or oxidized with oxygen.

Vannamei Shrimp Probiotics and Its Benefits For Cultivation

Vannamei shrimp probiotics are essential in aquaculture, to be precise, to maintain shrimp health. Moreover, if the cultivation is carried out in intensive or super intensive type ponds with a high stocking density.

Before using probiotics, farmers used antibiotics to treat health problems in shrimp. However, people gradually realize that the use of antibiotics creates antimicrobial resistance, which harms the environment.

Through this article, we will learn more about vannamei shrimp probiotics and their benefits.

Also Read: 7 Easy Ways to Cultivate Vannamei Shrimp For Beginners

What is Vannamei Shrimp Probiotic?

Vannamei shrimp probiotic is a feed supplement in the form of live microbes that are beneficial for vannamei shrimp by providing balance to the intestines. Through the administration of this probiotic, the use of feed during cultivation can become more efficient.

However, in aquaculture, probiotics do not only play a role in the digestive system of farmed animals. Still, they can also increase the nutritional value, immune system, and improve water quality.

Types of Probiotics for Aquaculture

Vannamei shrimp probiotics — Source: DELOS Documentation

Probiotics for aquaculture are broadly divided into two types, namely, aqueous probiotics and gut probiotics. Each of these probiotics

1. Aqueous Probiotics

As the name suggests, the use of water probiotics in vannamei shrimp cultivation by mixing them directly into pond water. While the way it works is by inhibiting the development of pathogenic bacteria and improving water quality.

Usually, the bacterial strains used in this probiotic are Bacillus acidophilus, Bacillus subtilis, Bacillus licheniformis, Nitrobacter spp., Aerobacter, and Saccharomyces cerevisiae.

2. Feed Probiotics

Feed probiotics are a probiotic used to improve the microbial balance in the intestines of vannamei shrimp. Usually, it is used by mixing the bacterial strain into the shrimp feed.

While the types of bacterial strains used include Lactobacillus or Saccharomyces cerevisiae, nitrifying bacteria, Streptococci, Roseobacter, and Bacillus sp. This bacterial strain works in the shrimp’s gut by modifying its microbial balance and inhibiting the growth of harmful microbes.

The use of probiotics provides positive benefits and impacts in vannamei shrimp cultivation. Some of these benefits include:

1. Stimulating Shrimp Immune System

The bacterial strains in probiotics act as immunostimulants to increase the body’s immunity in vannamei shrimp. This immune boosting can be done in three ways, namely:

Increase macrophage activity
Increasing the production of systematic antibodies in the form of immunoglobulins and interferons
Increase local antibodies on mucous surfaces such as the intestinal wall.

2. Producing Bad Microbial Growth Inhibiting Compounds

Probiotics with lactic acid bacteria and Bacillus strains can produce several compounds that can inhibit the growth of harmful microbes. One of the most numerous and essential is the bacteriocin compound, a protein produced by certain strains.

3. Increased Nutritional Competition in Shrimp Intestines

Theoretically, nutrient competition plays a vital role in the composition of organisms in the vannamei shrimp gut. Increasing the presence of specific bacterial strains through probiotics may decrease the available substrate for other bacterial populations.

With competition for space in shrimp’s intestine or digestive tract, it can be an antagonistic mechanism for colonizing pathogenic bacteria by probiotics.

4. Avoiding the Disadvantages of Using Antibiotics

The use of antibiotics as a way to cure diseases in animals and humans has been around for a long time. However, antibiotics have a negative impact if used in the long term, namely the presence of bacterial resistance.

Therefore, probiotics can be a choice to avoid the harmful effects of these antibiotics.

5. Stimulates Growth and Improves Shrimp Nutrition

Not only feed with high nutrition, vannamei shrimp cultivation also requires protein content and good bacteria as well as several other supplements to maintain the health and growth of shrimp.

In this case, probiotic bacteria are the best choice for farmers. The reason is that, in several studies, it was found that shrimp growth can be more optimal with the presence of probiotics.

Challenges in Aquaculture Industries: Building a Sustainable Future

Aquaculture is cultivating aquatic organisms, which is increasingly relied upon to meet the growing demand for seafood consumption and reduce fishing practices in the ocean. Despite offering significant potential for food security and economic growth, several challenges in aquaculture require careful consideration and innovative solutions.

In this article, we will further discuss the challenges in aquaculture and the steps taken to ensure the long-term sustainability of this industry.

Also Read: Get to Know the Vannamei Shrimp as a Farmers’ Favorite

Challenges in Aquaculture

1. Environmental Impact

Environmental impact is the biggest challenge in aquaculture that needs to be addressed if cultivation practices are not carried out properly. Responsible practices are essential From waste management to using feed and medications.

To tackle this challenge, stakeholders in the aquaculture industry must focus on implementing sustainable practices such as optimizing feed efficiency and adopting sustainable aquaculture systems with proper waste management.

2. Disease Management

Disease outbreaks pose a significant threat to the aquaculture industry. They can cause economic losses and environmental degradation. Therefore, industry stakeholders must be prepared and vigilant in disease management.

Some measures that can be implemented for disease management in aquaculture include strict biosecurity protocols, vaccination programs, and the development of disease-resistant strains through selective breeding and genetic improvement.

Adopting technology with early monitoring and detection systems through applications like AquaHero can also be a viable option for farmers.

3. Food Production

Food production is a problem that can be addressed through aquaculture, but it can become another issue if not practiced well. Seafood is an important source of nutrition for individuals, besides being more affordable.

By 2030, 62% of seafood supplied and consumed by humans will come from aquaculture. Furthermore, the UN projects that by 2050, there will be 9.7 billion people on Earth, leading to a continuous increase in food demand.

4. Regulatory Framework

Establishing effective regulations and governance structures is crucial for sustainable aquaculture practices. The development of the aquaculture industry and environmental conservation must always be balanced.

Therefore, transparent and science-based regulations and policies are needed to ensure responsible practices, encourage investment, and build public trust.

In this regard, collaboration among governments, industry associations, and other stakeholders is necessary to develop strong standards and guidelines that support responsible aquaculture practices.

5. Social Acceptance

Perceptions and public acceptance of aquaculture are also one of the challenges in the industry. Concerns about environmental impact, animal welfare, and food safety can influence public support for this industry.

Socialization programs to increase awareness can help address this issue while promoting the positive aspects of aquaculture itself. For example, addressing overfishing, providing sustainable protein sources, and involving local communities directly.

6. Water Quality Management

Another issue in aquaculture is water quality management. Aquaculture practices heavily rely on water quality management, and the quantity and quality of water supply used to rear aquatic organisms are crucial for successful cultivation.

Almost all aquaculture commodities depend on optimal water quality parameters such as dissolved oxygen, temperature, salinity, hardness, ammonia, nitrite, and pH as the environment in which they live and grow.

5 Characteristics of Intensive Vannamei Shrimp Pond You Should Know

An intensive vannamei shrimp pond is a type of pond that was developed as a means to increase the productivity of vannamei shrimp aquaculture. However, on the other hand, intensive ponds also produce more waste due to their high stocking density.

The waste from this intensive pond comes from the feed given to vannamei shrimp, usually in the form of carbon, nitrogen, and phosphorus compounds. These three compounds can decompose naturally on their own but in a longer time than one cultivation cycle. Therefore, waste will accumulate if the leftover materials from a prior process are not correctly disposed of.

In addition to residual waste, the calculation and layout of intensive vannamei shrimp ponds are more complex when compared to other types of ponds.

Also Read: Latest Vannamei Shrimp Prices in Indonesia

Characteristics of Intensive Vannamei Shrimp Pond

Vannamei shrimp-intensive ponds have unique characteristics that are different from other types of ponds. This is influenced by the stocking density of this type of pond. The characteristics of vannamei shrimp ponds are as follows:

1. Not Affected by Tidal Cycles

Water sources in intensive ponds do not depend on the ebb and flow of seawater. So, even when the sea water recedes, the water in the pond will not be affected.

2. Regularly Shaped Pond Plot

Intensive ponds have a regular pond shape. Usually, it is a square with an area of 0.2-0.5 ha per plot.

3. Using Aeration System

Another characteristic of intensive ponds is the existence of an aeration system in ponds that is useful for increasing dissolved oxygen in pond waters. This aeration system is usually supported by waterwheels, blowers, source pumps, and other equipment.

4. High Stocking Density

In an intensive cultivation system, it is necessary to adjust the stocking density so that production results can be maximized with minimal costs.

Stocking density determines the level of technology required in the cultivation system.

5. Rely on Artificial Feed

Considering the high stocking density of shrimp fry in intensive pond types, the need for feed is also high. Therefore, since the fry is stocked, the need for feed is immediately met with artificial feed.

Also Read: Getting to Know the DOC Term in Shrimp Farming

Purpose of Adjusting Vannamei Shrimp Stocking Density

The stocking density of vannamei shrimp fry must be adjusted to the capacity of the existing pond. This is because the stocking density affects the pond’s productivity and the costs incurred for cultivation.

1. Maintain Good Water Quality

Water quality in vannamei shrimp culture is influenced by feed residues and faeces. The greater the density of vannamei shrimp during cultivation, the more feed residues and manure are produced.

If there is too much manure and leftover feed is in the water, water quality conditions can be disturbed and even toxic.

2. Maintain the Growth of Vannamei Shrimp

The stocking density of vannamei shrimp that is not adjusted to the capacity of the pond can cause the cultured shrimp not to grow well. This is because shrimp will fight for space and nutrients from food which can cause shrimp growth to be slow if the stocking density is too high. Meanwhile, if the stocking density is too low, the space utilisation will be less than optimal.

3. Avoid Disease Attacks

Adjusting the stocking density of white shrimp can also prevent shrimp from disease during cultivation. If the stocking density is too high, the risk of death of vannamei shrimp during disease is also quite high, and vice versa.

4 Types of Vannamei Shrimp Harvest Time

The vannamei shrimp harvest time is done when the shrimp are more than 100 days old with an average weight of 20 grams per head. However, shrimp must be harvested early in special conditions such as mass mortality.

Harvesting is the process of taking shrimp from ponds that are more than 100 days old and weigh up to 20 grams per head. This activity is the most anticipated activity by the farmers as the final part of cultivation.

Generally, vannamei shrimp harvest time is done when the shrimp have reached a certain age. However, under special conditions, other types of harvest must be done. For example, when the capacity of the pond is insufficient or when there is a mass death of shrimp.

In one cultivation cycle, vannamei shrimp can be harvested at more than 100 days old or approximately three months old. However, if the pond’s capacity is close to the maximum limit, a partial harvest is usually carried out first to avoid increasing shrimp mortality due to lack of oxygen.

Partial harvest of vannamei shrimp is usually done when the DOC (day of culture) reaches 60-70 days. This is one of the vannamei shrimp cultivation strategies so that shrimp growth remains normal and stable.

2. Partial Harvest

Partial harvest in vannamei shrimp culture is usually done to reduce the pond’s biomass or capacity. Because if the capacity of the pond has passed the maximum limit, the growth of shrimp becomes less than optimal.

3. Abnormal Harvest

The next type of shrimp harvest is abnormal harvest. This harvest occurs when the shrimp in the pond experience several symptoms, including a mortality rate of more than 100 heads per day for three consecutive days, slow growth of shrimp, and a decrease in feed daily.

4. Emergency Harvest

The last one is emergency harvest which carried out due to an emergency condition. For example, when shrimp are infected with a deadly virus that causes mass deaths of up to 1000 individuals per day, embankments slide, electricity goes out, and waterwheels die.

Vannamei Shrimp Life Cycle

Before becoming a shrimp you often find at supermarkets, vannamei has several stages of its life cycle that must be passed. Starting from eggs, nauplius, protozoea, mysis, post-larvae, juveniles, sub-adult, to adult shrimp.

1. Egg

Female shrimp will mate with male shrimp and released up to hundred thousands eggs into the water.

2. Nauplius

The fertilized egg will then develop to the nauplius stage with a size of 0.32-0.58 mm. At this stage, vannamei shrimp do not yet have a perfect digestive system. Meanwhile, they get their food from the yolk sac.

3. Protozoea

Nauplius, which doesn’t have the yolk sacs and undergoes a molt, then turns into protozoea. At this stage, the vannamei begins to need food from the surrounding environment, such as phytoplankton.

4. Mysis

Vannamei will then undergo three moltings and turn into a mysis. The most visible development of this stage is the emergence of swimming legs (pleopods) and the addition of body segments. At the mysis stage, the size of the vannamei shrimp reaches 3.50-4.80 mm.

5. Post-larva

When it reaches the post-larva stage, the vannamei shrimp looks like an adult shrimp. At this stage, the shrimp have started to actively move straight ahead. Meanwhile, for farmers to find out the age of the post larvae, add a number behind it, for example, PL 1 for one-day-old post-larva.

6. Juvenile

The shrimp are referred to as juvenile when it reaches PL 10 or post-larva aged ten days.

7. Sub-Adult

Yuwana which is 80-90 days old, can already be called a young shrimp or sub-adult shrimp. Usually, these young shrimp have reached a weight of 21-23 grams per head.

8. Adult Shrimp

To reach the adult shrimp that are ready to be harvested, young shrimp need 25-30 days with an average weight of 28-30 grams per head.
