Characteristics of Healthy Shrimp

1. Active Swimming and Responsive

The characteristics of healthy shrimp can be seen from the level of activity. Healthy shrimp will usually actively swim around and be responsive. For example, when fed, healthy shrimp will surface.

2. Clear and Bright Colored Body

Clear and bright body color can indicate that the shrimp is in a healthy condition. Meanwhile, shrimp with shells that are dull, faded, or discolored can be an indication of a health problem.

3. Hard Body Texture

Healthy shrimp have a hard and dense body texture. There should be no mucus or body that is soft to the touch.

4. Have a Good Appetite

A good appetite for shrimp can also be an indicator of healthy shrimp. Healthy shrimp will eat regularly and eat the food that has been provided.

5. No Signs of Stress

The last characteristic of healthy shrimp is the absence of signs of stress, such as being lethargic, hiding at the bottom of the pond, and showing signs of aggression towards other shrimp.

Also Read: 5 Tips on Managing Vannamei Shrimp Ponds

Characteristics of Diseased Shrimp

1. Lethargic or Weak

The first characteristic of diseased shrimp is that they appear lazy or weak. Usually, the shrimp will move slowly or even not move at all. Diseased shrimp will tend to stay on the bottom of the pond even when being fed.

2. Has Faded Color

Diseased shrimp have discolored or faded shells. In addition, several diseases such as myo disease and white spots can also trigger discoloration of the shrimp’s body.

3. Slimy or Mushy Texture

Diseased shrimp usually have slimy or mushy bodies. This slime usually covers the entire outside of the shrimp.

Parts of Sustainable and Environmentally Friendly Ponds

Ponds are places where shrimp, fish, and other aquaculture commodities are cultivated. In practice, parts of the pond should be manufactured according to sustainable and environmentally friendly standards.

As a place where shrimp grow, ponds must be designed and given special care to provide ideal conditions for shrimp. This pond consists of various essential parts to function correctly and produce high productivity.

Therefore, below we have summarized the parts of a sustainable and environmentally friendly pond that you can use as a reference.

Also Read: 5 Types of Shrimp Pond Aerators and Their Functions

Environmentally Friendly Parts of Ponds

1. Quarantine Pond

The first parts of the pond are quarantine ponds which function as water reservoirs with standard water quality standards. This quarantine pond is used as a water supply when changing new water to rearing ponds or reservoir ponds.

Quarantine ponds are placed before rearing ponds to facilitate water distribution. Optimally, a quarantine pond can accommodate between 30-50% new water, depending on the level of technology applied.

2. Water Distribution Channels

The next part of the pond is the water distribution channel which helps divide water into each rearing pond. Usually, the water distribution channel is placed on a strategic side to facilitate the distribution of water.

For ponds that are small in scale, this pond is usually combined with a quarantine pond to save land.

3. Cultivation Pond

The fry is stocked and raised in a rearing pond until harvest time. Ideally, this pool is located in the middle of the pond. Meanwhile, the area of the pond depends on the cultivation system being run, for example, for an intensive system between 2000-4000 square meters.

Rearing ponds can be square or circular. However, ideally, each corner should be obtuse to facilitate water and waste management at the bottom of the pond.

4. Sludge Pond

As the name suggests, a sludge pond is a storage area for sludge originating from the rearing pond. This pond is located near the water and waste disposal center to facilitate its operation.

5. Reservoir Pond

Reservoir ponds or also known as biofilters, are ponds used to filter organisms, pests, and diseases that can harm shrimp. These ponds are usually located after settling patches.

In reservoir ponds, seaweed, mangrove shells, oysters, and mangrove plants are usually found, which function as biofilters to absorb toxic substances such as NH3, CO2, and nitrites in the water.

6. Waste Treatment Pond

The next part of the vannamei shrimp pond is the waste treatment pond, a reservoir for wastewater from the grow-out pond. The water will be chemically and biologically sterilized in this pond before being discharged into the sea.

7. Central Sewer

The central drain is a water disposal system in the middle of a shrimp-rearing pond. This channel is made of cast cement in a round shape to drain water toward the sewer. While in terms of size, it can be adjusted to the needs of each pond.

8. Monik’s Door

The last parts of the pond are monik doors and water discharge gates. This door is made of cast cement and buis concrete, with a control door on the bund’s inner side.

The size of the monic gate depends on the pond area and the existing bund construction. In simple ponds, the drain gate is usually not made of concrete but of wood or PVC.

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

Manajemen pakan udang — Source: DELOS Documentation

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.

3. Shrimp Health Management

Manajement kesehatan udang — Source: DELOS Documentation

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.

Cultivating Vannamei Shrimp with Biofloc System

Vannamei shrimp biofloc has become a popular cultivation system lately. Biofloc technology was first applied by Dr. Yoram Avnimelech in Israel and experienced immediate success. Finally, the biofloc system was also implemented in shrimp ponds in Indonesia.

In a way, the vannamei shrimp aquaculture biofloc system is a form of innovation to address feed problems experienced by farmers. The reason is by implementing the biofloc system, the shrimp’s natural feed supply becomes more abundant.

Farmers who want to apply the biofloc system to vannamei shrimp cultivation must practice it correctly because a bit of wrong in practice can be fatal.

Therefore, here we have summarized the method of cultivating vannamei shrimp using the biofloc system, which you can use as a reference.

Also Read: Get to Know Myo (IMNV) Disease in Vannamei Shrimp and Its Characteristics

What is the Biofloc System?

Biofloc is a bunch of microorganisms such as bacteria, protozoa, fungi, plankton, and organic matter from undecomposed waste.

While the biofloc system attempts to utilize leftover shrimp feed waste to become microbial feed, the rest of the feed waste will be degraded, and the microbes in it will develop and multiply until, finally, the floc is produced.

Floc can be a good source of protein for shrimp. This is because decomposed organic compounds contain carbon (C), hydrogen (H), oxygen (O2), nitrogen (N), and phosphorus (P) compounds.

With the vannamei shrimp biofloc, the farmers can reduce operational costs, which are usually used to purchase feed. This is because the biofloc system can lessen the Feed Conversion Ratio (FCR) while minimizing disease outbreaks.

However, keep in mind that the biofloc system does not affect overall farm productivity because the microorganisms formed only serve as additional feed.

Vannamei shrimp cultivation using the biofloc system can be applied to start from intensive to super-intensive system ponds that have high stocking densities. However, firstly the pond must have a high level of aeration with the appropriate wheel position. The pond must be covered with concrete or high-density polyethylene (HDPE), as well as additional pellets and molasses.

In addition, farmers must always carry out biofloc control during vannamei shrimp cultivation.

How to Cultivate Vannamei Shrimp with the Biofloc System

Until now, many Indonesian shrimp farmers are interested and have applied the biofloc system. However, few also experience failure due to a lack of understanding of this technology.

Therefore, here is a method of cultivating vannamei shrimp with the biofloc system that you can practice.

1. Prepare the Pond very Well

The vannamei shrimp biofloc system can only be applied in some ponds. Particular standards must be met so that the cultivation of vannamei shrimp goes well and does not suffer losses.

The standards for pond ponds that must be met include pond sizes adapted to the cultivation system, ponds that do not leak and have been coated with thick HDPE concrete or plastic, sound aeration systems, and pond heights ranging from 0.8-3 meters.

2. Choose the Right Probiotic Bacteria

The vannamei shrimp biofloc system relies on probiotic bacteria for each pond. Bacillus subtilis is a type of probiotic bacteria that can be selected because this bacteria can decompose nitrogen elements properly and can maintain water quality.

Another type of bacteria that can be used is Bacillus cereus which can form bacterial flocs while controlling the growth of green algae.

3. Make Biofloc Starter

After selecting probiotic bacteria, the next step is to make a biofloc starter. This stage is the same as fermentation to increase the number of bacteria in the pond, which functions as a quality guard for Biopolymer (PHA), which helps the process to suppress harmful pathogens.

4. Spread High-Quality Shrimp Fry

When the ponds with biofloc technology are ready, farmers can start spreading the shrimp fry into the pond. However, to get the best quality cultivation results, choose high-quality and certified fry.

5. Perform Proper Feed Management

When the flock has not been formed, farmers can provide feed like ordinary vannamei shrimp cultivation. For example, feeding in pellets twice a day according to needs.

Then when the flock has begun to form, you can start reducing feeding because this is where the role of floc is as a natural food source for shrimp. With this flock, farmers can reduce FCR and save farm operational costs.

6. Ensure Dissolved Oxygen Supply (DO) is fulfilled

When choosing to use biofloc technology, farmers must ensure a continuous supply of dissolved oxygen (DO). This is because ponds that lack an oxygen supply can cause the shrimp in them to die.

To ensure that the supply of dissolved oxygen (DO) is met, farmers can use aerators or waterwheels as additional tools to supply extra oxygen. In addition, make sure the number of aerators or water wheels per the pond’s area.

In biofloc vannamei shrimp farming, the aerator or waterwheel not only acts as an oxygen supply but also keeps the biofloc suspended. However, it should be noted that high levels of suspended biofloc biomass can cause a decrease in pond water quality and ultimately result in crop failure.

Advantages and Disadvantages of the Biofloc System

The biofloc system is only sometimes superior to the vannamei shrimp farming system. There are positive and negative sides to this cultivation system. Following are the advantages of biofloc technology:

Very high biosecurity
Production capacity and carrying capacity are usually 5-10% higher
Shrimp grow bigger with lower FCR
15-20% lower production costs

Meanwhile, the shortcomings of the biofloc system include the following:

Requires a high energy supply for the aerator
Failure of energy supply for more than 1 hour can be fatal and critical
The biofloc pond must be lined
Technicians must receive specific knowledge and training to understand this technology fully.

Disease

Recognize 7 Characteristics of AHPND Disease in Vannamei Shrimp Before It’s Too Late

Acute Hepatopancreatic Necrosis Disease, also known as AHPND disease in vannamei shrimp, is a problem that farmers often face. This disease can cause mass death resulting in heavy losses and harvest failure.

Acute hepatopancreatic necrosis disease (AHPND) originates from a bacterial infection with a strain of Vibrio parahaemolyticus (Vp AHPND). This disease is also known as early mortality syndrome (EMS), which can cause farm productivity to decrease by up to 60% and result in considerable losses.

To be on time in carrying out mitigation if attacked by AHPND, farmers must know its characteristics. Here we summarize some of the characteristics of Acute Hepatopancreatic Necrosis Disease (AHPND) that you can use as a reference.

Also Read: Vannamei Shrimp Probiotics and Its Benefits for Cultivation

What is AHPND?

Acute Hepatopancreatic Necrosis Disease or AHPND disease in vannamei shrimp is a disease caused by bacterial infection with the Vibrio parahaemolyticus (Vp AHPND) strain.

AHPND disease first appeared in China in 2009 and then spread to Vietnam in 2010, Malaysia in 2011, Thailand in 2012, Mexico in 2013, the Philippines in 2015, and South America in 2016.

As a result of the outbreak of AHPND disease in vannamei shrimp in these countries, shrimp production has decreased by up to 60%, resulting in considerable losses.

Not only attacking vannamei shrimp, but AHPND disease also attacks other shrimp species, such as P. monodon (tiger prawn), M. rosenbergii (giant prawn), and other types of crustaceans.

Usually, shrimp in the early life phase is more susceptible to AHPND infection. Furthermore, AHPND attacks the digestive glands (hepatopancreas) and destroys hepatopancreatic cells R (resorptive), B (blister), F (fibrillar), and E (embryonic) which results in organ dysfunction leading to massive death.

Also Read: Get to Know Myo IMNV Disease in Vannamei Shrimp and Its Characteristics

Characteristics of AHPND Disease in Shrimp

Vannamei shrimp infected with AHPND usually look lethargic and exhibit abnormal swimming behavior. Apart from this, here are other characteristics when shrimp have been infected with Acute Hepatopancreatic Necrosis Disease.

1. Infecting the Early Life of Shrimp

Acute Hepatopancreatic Necrosis Disease in vannamei shrimp infects in the early phase of cultivation, from the 1st to the 35th day of cultivation. Usually, this will be followed by the mass death of up to 100% of the stocked shrimp.

2. Shrimps Have No Appetite

AHPND disease causes shrimp to have no appetite and thus show symptoms of anorexia. Furthermore, this symptom is followed by emptying the digestive tract and loss of tissue pigmentation.

3. Shrimp growth slows down

Shrimp with no appetite due to AHPND infection indirectly triggers slower shrimp growth. This is because the growth of shrimp is directly influenced by the food consumed.

4. The digestive tract becomes empty

Shrimp that has been infected with AHPND disease show an empty digestive condition. Because this disease attacks the digestion of shrimp directly.

5. Hepatopancreas Turns Pale

When infected with AHPND disease, the vannamei shrimp hepatopancreas tissue will experience fragility at the beginning of the infection. Then as the disease progresses, this tissue will become pale and rigid.

6. Appearance of Black Spots on the Hepatopancreas

After becoming pale and rigid, the next phase will appear with black spots or fine lines on the hepatopancreas. These black spots indicate foci of melanization in the tubular cells of the hepatopancreas.

7. High Mortality Rate

The death rate from AHPND disease in vannamei shrimp reaches 100% in most countries. However, in several other countries, it shows the opposite, namely a low death rate.

The difference in tolerance for death rates is because regions with low mortality rates have had a history of similar diseases. This makes the vannamei shrimp’s immune system better compared to other areas.

How to Overcome AHPND Disease in Shrimp

Only now the treatment for AHPND disease in vannamei shrimp is known with certainty. However, farmers can take preventive measures in farm management, for example, by aeration, providing appropriate feed, and maintaining pond water quality.

Diseases caused by pathogenic bacteria in vannamei shrimp are generally controlled using appropriate management strategies, including immunostimulant supplementation, prebiotics, probiotics, maintaining water and feed quality, and maintaining pond aeration.

However, this control cannot stop the spread of the disease when the vannamei shrimp have been attacked by Acute Hepatopancreatic Necrosis Disease. Conventional approaches such as stopping feeding or giving disinfectants can be another solution, although the success rate is also relatively low.

Disease

Get to Know Myo IMNV Disease in Vannamei Shrimp and Its Characteristics

Myo disease in white shrimp is also known as IMNV disease. This disease is caused by the Infectious Myonecrosis Virus (IMNV), which damages muscle tissue in shrimp. As a result, from the body tissue until the tail of the shrimp dies and the color becomes red.

Myo disease was first discovered in Brazil in 2002. This disease is classified as malignant and deadly in vaname shrimp, with a mass mortality rate reaching 70% of the total shrimp stocked in ponds.

While in Indonesia, this disease was first discovered in 2006, precisely in one of the ponds in Situbondo Regency. Since then, research has been carried out on this shrimp disease.

So what exactly does Myo IMNV disease look like in vannamei shrimp, and what are its characteristics? Check out the following explanation.

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

What Is Myo Disease in Vannamei Shrimp?

Infectious Myonecrosis Virus (IMNV), or myo disease, attacks white shrimp and can cause substantial economic losses due to mass deaths.

IMNV virus can infect all stages of shrimp life, including post-larvae, juveniles, to adult shrimp. However, more deaths were found at the stage of young to adult shrimp.

Meanwhile, the transmission of this virus can occur in two ways, namely horizontally and vertically. Cannibalistic behavior in infected shrimp can be a way of horizontally transmitting this disease. While vertically, this virus can be transmitted from the parent to the fry it produces.

Vannamei Shrimp Cultivation Prospect

The increasing global market demand for vannamei shrimp has made many people start looking at this business. Both include small-scale ponds, such as traditional ponds, and large-scale ponds, such as intensive and super-intensive ponds.

Vannamei shrimp has a fast growth rate, shorter cultivation time, and better environmental resistance when compared to other types of shrimp. In addition, vannamei shrimp are also relatively more resistant to disease.

Since it was officially introduced in Indonesia in 2001, vannamei shrimp have immediately become the prima donna of farmers. Moreover, due to disease, tiger prawn cultivation continued to decline at that time.

Indonesia has long been one of the largest shrimp exporters in the world. In 2021, Indonesia was ranked 4th after India, Ecuador, and Vietnam.

However, considering that Indonesia is the largest maritime country in the world, the potential stored in vannamei shrimp production still has relatively large prospects. If optimized, Indonesia can become a leader in shrimp producers and exporters.

Until now, of the total ponds in Indonesia, 75% of them can only contribute 10% of the total quantity of exports. The lack of full maintenance and management of ponds causes this.

Therefore, until now, the prospect of vannamei shrimp farming is still quite tempting. Given the broad market potential, environmental conditions and human resources support Indonesia.

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.

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

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.
