Tips for Providing Minerals for Shrimp Ponds

Minerals for shrimp ponds play an important role in stabilising pH, stimulating plankton growth, and breaking down harmful compounds in the pond. There are two types of minerals in ponds: from the aquatic environment and those from feed.

The mineral content in ponds can fluctuate during cultivation, both in quality and quantity. This is influenced by shrimp assimilation, water exchange, and seepage.

In addition to benefiting shrimp, minerals also support the process of plankton photosynthesis in ponds. If plankton in the pond is stable, the environment will also be good.

So, what are the tips for providing minerals for shrimp ponds for optimal cultivation results? Find out more in the following article!

The Importance of Sufficient Minerals for Shrimp Ponds

The mineral requirements for vannamei shrimp range from 2-5% of the total shrimp feed. However, in ponds with higher stocking densities, the required mineral supply should also be higher.

If minerals for shrimp ponds are insufficient or unbalanced, the consequences can be fatal. This can range from disturbances in the pond ecosystem, and shrimp health problems, to decreased productivity and quality of harvests.

A lack of minerals in shrimp ponds can also result in microorganisms such as plankton not thriving properly. This can also lead to a decrease in water quality, which can cause shrimp to become stressed and more susceptible to pathogen infections.

Tips for Providing Minerals for Shrimp Ponds

1. Choose the Needed Minerals

Select minerals for shrimp ponds according to the needs of the cultivated shrimp. Some common minerals important for shrimp growth include Calcium, Magnesium, Sodium, Potassium, Phosphorus, Chlorine, Sulfur, Iron, Copper, Manganese, Zinc, Cobalt, Molybdenum, Chromium, Selenium, Fluorine, Iodine, and Nickel.

2. Pay Attention to Calcium Levels

Calcium is a crucial micromineral for the formation of strong shrimp shells. Ensure an adequate amount of calcium in the pond water, either through direct supplementation or by adding it to the feed.

3. Provide the Right Dosage

Minerals for shrimp ponds should be in the correct composition and needed by the shrimp in the pond. Avoid giving too many minerals, especially if not needed, as this can cause overdoses and have negative impacts on shrimp health and overall water quality.

4. Consider Environmental Factors

Take into account environmental factors such as water quality parameters before providing minerals for shrimp ponds. Different water environment conditions or conditions not being optimal can affect mineral absorption by shrimp.

5. Continuously Monitor Mineral Balance

Changes in mineral balance can occur over time due to various factors, including shrimp growth, water usage, and decomposition of organic matter.

Monitoring mineral levels in ponds can be done by routinely testing the water. This includes chemical, physical, and biological testing.

Disease

11 Types of Shrimp Diseases that Often Occur During Cultivation

Shrimp disease is one of the factors causing failure that must be overcome during cultivation. What’s more, these diseases can also cause mass mortality which can lead to significant economic losses and decreased production.

Various influencing factors cause disease outbreaks, from pathogens, poor environmental conditions, and pond management to shrimp being carriers of shrimp that have previously been infected with the disease.

So, what types of diseases are often encountered during shrimp cultivation? Check out the following explanation.

Also Read: The Threats of Nitrite in Shrimp Ponds and How to Overcome It

Factors Causing Vannamei Shrimp Disease

1. Pathogen

The most common causes of vannamei shrimp disease are viruses, bacteria, fungi, and parasites. Some examples of conditions in shrimp caused by pathogens include White Spot Syndrome Virus (WSSV), Early Mortality Syndrome (EMS), Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV), Taura Syndrome Virus (TSV), and Vibriosis.

The spread of diseases caused by pathogens in shrimp can be transmitted through contaminated water, feed, or equipment and can spread quickly in ponds.

2. Poor Environmental Conditions

Environmental conditions are also directly a factor causing disease outbreaks in shrimp. Poor water quality, high levels of pollutants, and low dissolved oxygen can make shrimp more susceptible to disease.

Not only that, stressful conditions such as drastic and sudden changes in temperature or salinity can also increase the risk of disease in shrimp.

3. Poor Farm Management Practices

Poor pond management is a trigger factor for the emergence of subsequent diseases. This management includes feed, water quality, shrimp health, cultural waste, and biosecurity.

The overall management of this pond management must be synergized and well-practiced. This is because if one is lacking, it will directly impact the shrimp and increase their potential to get sick.

4. Import of Infected Shrimp

Indonesia takes a lot of shrimp fry from other countries, for example, the United States. However, before these imported fries are cultivated, they must first check the quality of the fry to ensure they are not attacked by disease or become carriers.

Imported fry already infected can become carriers for other fries in the same pond. This makes the spread of the disease faster and more massive.

Also Read: Get to Know the Covert Mortality Nodavirus (CMNV) which Can Attack Vannamei Shrimp

Types of Shrimp Diseases That Often Infect

1. White Spot Syndrome Virus (WSS)

White spot disease or white spot disease is a disease in vannamei shrimp that is highly contagious and deadly. A virus causes this disease from the crustacean group. In addition, environmental factors can also trigger white spot disease infection.

The appearance of white spots and redness on the shrimp’s body indicates early symptoms of white spot disease. Over time, shrimp attacked by this disease will die slowly because it causes them to lose their appetite and eventually die.

2. Early Mortality Syndrome (EMS)

Early Mortality Syndrome (EMS), also known as Acute Hepatopancreatic Necrosis Disease (AHPND), is a disease that attacks pond shrimp and is characterized by sudden death, loss of appetite, and abnormal swimming behaviour.

This type of disease is the most frightening for fish farmers. This is because the death rate from EMS disease can reach 100% of the population.

3. Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV)

Infectious Hypodermal and Hematopoietic Necrosis Virus is a type of disease caused by a virus that causes shrimp to experience defects in the abdomen and snout.

Shrimp infected with IHHNV will show signs of swimming behaviour to the surface of the water, then remain motionless and eventually sink to the bottom of the pond. This behavior will continue until the shrimp die.

4. Taura Syndrome Virus (TSV)

Taura Syndrome Virus is a disease that first appeared in the Taura River, Ecuador. Meanwhile, transmission can occur through water and direct contact between shrimp or other crustaceans, carriers of the TSV virus.

The Taura Syndrome Virus has spread only in Colombia, Peru, Brazil, Hawaii, Texas, and Florida until now. Meanwhile, in Asia, no shrimp has been infected with this virus.

5. Vibriosis

Vibriosis is a type of shrimp disease caused by the attack of Vibrio sp. When shrimp are infected with vibriosis, symptoms will appear in a thin skin, black sores on the body, and incomplete shrimp limbs.

Vibriosis disease is no less deadly than other illnesses found in shrimp. The death rate caused by this disease can reach 85% of the population.

6. White Feces Disease

White feces disease, also known as white feces disease, was first detected in Indonesia in 2014. This type of disease causes the death of up to 40% of the total name shrimp intensive pond population.

Symptoms caused by shrimp infected with White Feces Disease include decreased appetite, shrimp intestines changing color to white and even looking empty due to lack of food intake, abnormal shrimp growth, and feces floating on the surface of the water.

7. Infectious Myonecrosis Virus (Myo/IMNV)

Infectious Myonecrosis Virus (IMNV) or Myo in vannamei shrimp is a type of disease that can cause mass death. Symptoms of shrimp infected with this disease are reddening of the lower segment of the shrimp’s tail. Then slowly, the shrimp will die and sink to the bottom of the pond.

Myo disease is caused by an RNA (Ribonucleic Acid) virus and is classified as malignant because it causes mass death in a short time when the shrimp are 60-80 days old.

8. Black Gill

Black gill disease in vannamei shrimp is caused by the genus Fusarium or fungus. Besides fungi, ciliates can also cause black gill syndrome.

Black gill causes normally white gills to darken in response to the presence of ciliates, the primary agents causing gill melanization, leading to damage to the respiratory surface.

The normal colour of shrimp gills is dull white. In the early stages of black gill disease, black spots appear on the gills. External signs of severely infected shrimp show black gills compared to normal ones.

All gills turn black, with some turning brown, which is the initial stage of black gill infection. The gill lamellae of shrimp infected with black gill show the presence of fungal spores.

9. Black Spot

Black spots, also known as black spots, can form on the body of shrimp. Shrimp shells are usually brown and may show black spots. These black spots usually appear after harvesting shrimp, indicating a decrease in shrimp quality.

The cause is a bacterium called Vibrio anguillarum, which thrives in saltwater at temperatures between 25 to 32 degrees Celsius. This bacterium is commonly found in pond environments and does not cause disease if its concentration is kept under control.

However, Vibrio bacteria can become dangerous when water quality in the ponds deteriorates, especially due to the accumulation of organic feed residues at the pond bottom. Decreased pond quality can trigger Vibrio bacterial growth. Additionally, direct sunlight on post-harvest shrimp can also accelerate the appearance of black spots on shrimp.

To prevent this, farmers can regularly clean the pond bottom of waste, including leftover feed and moult residues. They should also maintain water quality by monitoring plankton levels, increasing dissolved oxygen, providing sufficient minerals, and managing feeding to avoid overfeeding, which can make the pond bottom dirty.

10. Yellow Head

Yellow head disease increases mortality rates up to 100% within 3 to 5 days after infection. The triggering factors are sudden changes in pH and dissolved oxygen (DO) levels. Clinical symptoms usually appear 2-4 days after infection, with death occurring within 3 to 5 days.

Like WSSV disease, this disease is classified as a category C-1 pathogenic virus. Clinical symptoms of the yellow head disease include increased shrimp appetite followed by a drastic decrease until the late stages of the disease, changes in the colour of the shrimp tail to reddish with a yellowish head, and paleness or brownish colouration in the gills.

These signs may not always be visible in infected shrimp; therefore, accurate diagnosis requires gill staining and hemolymph examination and can be further confirmed through RT-PCR.

11. Enterocytozoon hepatopenaei (EHP)

Enterocytozoon hepatopenasei (EHP), also known as EHP disease in shrimp, is a disease caused by the microsporidian parasite. This parasite leads to slow growth in shrimp.

EHP disease in shrimp was first detected in 2004 in Thailand in cultured giant tiger shrimp. In Indonesia, this disease was first reported in 2015.

Although EHP disease does not directly cause shrimp mortality, its impact is felt through a decrease in shrimp growth rate during cultivation. This can result in significant differences in shrimp size within a single cultivation pond.

Export

What is the Projection for the Increase in Indonesia Shrimp Exports in 2024?

The increase in Indonesian shrimp exports is one of the major targets set by the Ministry of Marine Affairs and Fisheries (KKP) in 2024. Since 2020, the KKP has set an ambitious target to increase shrimp exports by 250 percent.

This 250% figure is based on the national shrimp production throughout 2020, which reached 856,753 tons. This significant increase in shrimp production has given the KKP confidence in achieving the target of increasing Indonesia’s shrimp exports in 2024.

Of course, this has sparked discussions about the strategies that will be implemented to achieve this target. Find out more in this article:

Is This Target Realistic?

According to the National Coordinator of Destructive Fishing Watch (DFW) Indonesia, Moh. Abdi Suhufan, the target of increasing shrimp export volume by 250% is quite realistic if accompanied by breakthroughs and innovations. Of course, this requires good and strong cooperation from all stakeholders involved in the aquaculture sub-sector.

Furthermore, several fundamental issues have been overlooked by the KKP which could potentially hinder the achievement of this target. These issues are related to shrimp production processes, land tenure status, water channel conditions, water availability for cultivation, and so on.

According to Suhufan, if the KKP only intervenes in providing the necessary facilities and infrastructure such as seedlings, water gates, and generators, this alone cannot drive a significant increase in shrimp production figures, which will certainly affect the volume of shrimp exported.

Also Read: Key Success Factors in Building an Excellent Shrimp Export Image

1. The Importance of Shrimp Exports for National Fisheries

Shrimp exports have been a major contributor to the total value of national fishery product exports. In 2023, Indonesia’s shrimp export volume reached 241,200 tons with a total value of USD 2.16 billion.

While national shrimp production in 2022 reached 1.48 million tons with a value of IDR 92.69 trillion, showing a 21.25% increase compared to the previous year. However, the challenge lies in the significant production increase not being accompanied by a proportional rise in export value.

2. KKP’s Targets and Strategies

The Ministry of Maritime Affairs and Fisheries has set a target of a 250% increase in shrimp exports for 2024. KKP has implemented several strategies to achieve this target, including the construction of modern shrimp ponds in BUBK Kebumen.

Minister of Maritime Affairs and Fisheries, TB Haeru Rahayu, stated that achieving a 250 percent increase in shrimp export value relies on intensive and super-intensive shrimp ponds with higher productivity levels.

Application of Proper Biosecurity for Shrimp Ponds

Biosecurity for shrimp ponds involves a series of measures to prevent the entry of diseases into the pond area. The scope of biosecurity typically includes both the cultivation ponds and the entire pond area.

As the saying goes, “prevention is better than cure,” biosecurity is one of the best ways to minimize the risk of losses due to diseases during shrimp cultivation. However, its implementation must adhere to the established standards.

Applying biosecurity in shrimp ponds is essential to reduce the risk of cultivation failure. This applies to all types of ponds, ranging from traditional to super-intensive scales.

So, how can we properly apply biosecurity and adhere to the standard guidelines? Let’s explore further in this article.

Proper Application of Biosecurity

In the application of biosecurity for shrimp ponds, several aspects need to be considered, including juveniles (benur), shrimp feed, water, probiotics, and others.

1. Using High-Quality Shrimp Fry (Benur)

The first step in implementing biosecurity is to select high-quality and certified shrimp fry (benur). Ensure that the juveniles you choose are free from diseases to prevent infections and growth issues in the future.

2. Monitoring Water Quality in the Ponds

Water quality in the ponds is a critical aspect that must be monitored throughout the cultivation process. Regularly test water quality parameters to ensure that the pond water remains in optimal conditions. Additionally, you can add probiotics to improve water quality and enhance the shrimp’s immune system, protecting them from diseases.

3. Paying Attention to Accessibility

The accessibility of the pond, including the entry and exit of vehicles, people, and animals, can act as vectors that carry diseases into the pond. To prevent pathogens from entering the pond, you can implement the following activities:

Limiting the number of people entering the pond.
Restricting access to the cultivation area.
Establishing reporting and authorization procedures for pond entry (all visitors must report their presence).
To prevent wild animals from entering the pond, you can install deterrents such as bamboo fences, Crab Protecting Line (CPL), and Bird Scaring Line (BSL).

Another biosecurity measure is to use disinfectants at every pond entrance for people and vehicles entering the area. This helps prevent potential pathogens from being carried in by individuals or vehicles.

4. Following Biosecurity Protocols during Juvenile Stocking

During the juvenile stocking process, biosecurity protocols should be strictly followed and monitored, starting from the arrival of the juveniles to their release into the pond. The truck transporting the juveniles should pass through a wheel bath facility before entering the pond area. Additionally, the bags containing the juveniles should be disinfected (by dipping them in a disinfectant). Equally important is the requirement for all personnel involved in the stocking process to disinfect themselves before entering the cultivation pond, especially during manual stocking.

5. Pond Water Management

Implementing biosecurity in shrimp ponds also involves managing the water that flows in and out of the pond. This is typically achieved by providing storage tanks and treatment ponds to filter and disinfect the water before it enters the main pond.

In the storage tanks, physical treatments such as sediment settling, coarse particle filtration, and total organic matter reduction from the water source are conducted. The treatment ponds involve chemical processes aimed at killing pathogens before the water enters the cultivation pond, and one common method is disinfecting the water in the treatment pond. This reduces or eliminates the possibility of pathogens in the water entering the cultivation pond.

Likewise, the water leaving the pond must also be treated before being discharged into the environment to preserve the surrounding ecosystem. Directly discharging water without filtration could lead to environmental pollution and disease outbreaks due to pathogen contamination.

The Role of Biosecurity in Controlling Diseases in Shrimp Larvae

The presence of disease infections in shrimp ponds is one of the factors leading to failures in cultivation, especially when the infection occurs during the larval stage, causing socio-economic losses.

Viruses and bacteria cause diseases affecting shrimp. Controlling the spread of diseases is crucial to support sustainable aquaculture, and one effective strategy is the implementation of biosecurity measures in shrimp ponds, particularly starting from the stocking phase.

Some biosecurity measures to control diseases in shrimp larvae include:

Quarantining newly introduced shrimp broodstock.
Laboratory testing of broodstock for diseases.
Proper management of solid and liquid waste.
Regulating personnel and vehicles entering the cultivation area.
Regularly changing water to ensure its quality.
Conducting routine health screenings.

Implementing biosecurity to control the spread of pathogens can have positive effects, minimising the occurrence of diseases caused by bacterial and viral infections during the larval-rearing stage.

Consistent adherence to biosecurity policies by all pond personnel greatly supports the success of shrimp disease control. To ensure the success of biosecurity measures, shrimp farmers must document the regulations in writing.
