1. Determining the Right Harvest Time

Selecting the appropriate harvest time is essential to ensure optimal shrimp quality. Shrimp should be harvested when they have reached the desired market size. Allowing shrimp to stay in the pond for too long can lead to overgrowth and a decrease in shrimp meat quality.

2. Pond and Equipment Preparation

Before harvesting, make sure the shrimp ponds are clean from various debris and uneaten feed. The pond water should be in good condition and free from substances that can harm shrimp quality.

Also, ensure that harvesting equipment such as nets and storage containers are thoroughly cleaned and sterilized before use. Contamination from dirty shrimp equipment can lead to decay and a decline in shrimp quality.

3. Use of Anesthesia

Using anesthesia before harvesting can help reduce stress on shrimp and prevent damage to the shrimp’s quality. Anesthesia keeps the shrimp calm during the capture, transportation, and further handling processes. Some shrimp farmers use natural materials like coconut leaf extract or clove extract as anesthesia, which is safe for shrimp and does not leave harmful residues.

4. Proper Handling

During harvesting, farmers should be careful not to damage or cause injuries to the shrimp. Injured or damaged shrimp can become a source of infection for other shrimp.

Avoid stepping on shrimp or stacking them excessively. Additionally, do not expose shrimp to air for too long, as they need moisture to remain fresh.

5. Rapid Cooling

After harvesting, shrimp should be immediately cooled to slow down the decomposition process and maintain the freshness of the shrimp meat. Shrimp are perishable organisms, so proper storage temperatures are essential. Use ice or other cooling methods to keep shrimp at a low temperature during transportation from the pond to processing or market areas.

6. Sorting and Grading

Sorting and grading are other essential steps in maintaining shrimp quality. Shrimp should be sorted based on size and type. Larger shrimp usually command higher prices, while shrimp with good quality should be separated from defective ones. Grading ensures that the shrimp being sold meets consumers’ expected standards.

7. Proper Preservation Methods

If shrimp will not be sold or processed immediately, farmers should use appropriate preservation methods to maintain their quality. Common preservation methods include salting, drying, or applying low temperatures. The choice of preservation method should be based on market needs and the type of shrimp being harvested.

3. Managing Water Quality

Poor water quality can cause stress in shrimp, leading to weakened immune systems and increased susceptibility to diseases. Therefore, managing water quality is key to preventing disease spread in shrimp ponds.

Some actions to take in water management include:

a. Regular Checks

Farmers should routinely measure water quality parameters such as temperature, salinity, pH, dissolved oxygen, ammonia, nitrate, nitrite, alkalinity, and hardness. Regular checks can help identify changes that may affect shrimp health.

b. Adjusting Water Quality Parameters

Based on the measurement results, farmers should take action to improve any suboptimal water quality parameters. Treatments can be adjusted according to which water quality parameters need optimization.

4. Using Proper Feed and Feed Additives

The quality of the feed provided is essential for enhancing shrimp immunity. Poor-quality feed or feed that doesn’t meet their nutritional needs can weaken the shrimp’s immune system, making them more vulnerable to diseases. Farmers should ensure that shrimp receive feed with complete nutritional value to support growth and immune functions.

High-quality feed with suitable nutrient content for specific shrimp developmental stages should be used. Additionally, shrimp immunity can be supported by providing appropriate feed additives such as immunostimulants and probiotics. If there are signs of diseases in the shrimp, farmers should consult aquaculture experts or fish veterinarians for accurate diagnosis and proper disease management measures.

5. Implementing Strict Biosecurity

Implementing biosecurity measures is of utmost importance in preventing disease spread in shrimp ponds. All potential sources of disease transmission, whether from within or outside the pond environment, should be minimized.

a. External Biosecurity

Restrict access of outsiders to the shrimp ponds, and ensure that all shrimp farm equipment and vehicles entering the area are properly cleaned and sterilized to prevent disease transmission through external contamination.

b. Internal Biosecurity

Keep the shrimp farming environment isolated from other animals suspected of being carriers or disease vectors. Additionally, during pond changes, all workers should disinfect their hands and the equipment.

Understanding Sampling in Shrimp Farming and Its Benefits

During shrimp farming, farmers must constantly monitor the condition and growth of shrimp in the ponds. This is usually done through periodic sampling of the shrimp.

Sampling involves periodically observing the shrimp by taking several specimens from each pond for further examination. This activity is crucial to prevent adverse events in shrimp farming, such as disease outbreaks or suboptimal shrimp growth.

So, what are the objectives and benefits of sampling? Let’s find out in the following article!

Also Read: Using Probiotics for Shrimp Health, What’s the Impact?

What is Shrimp Sampling?

Shrimp sampling is the periodic observation of shrimp by taking several specimens from each pond for further examination. This is done to assess shrimp growth and condition and estimate their feeding requirements.

Sampling is typically conducted periodically from the time the shrimp post-larvae are stocked in the ponds until shortly before harvesting. Shrimp can be collected from different parts of the pond or through netting and then physically examined and tested in the laboratory.

Objectives of Shrimp Sampling

1. Assessing Shrimp Condition

One of the main objectives of sampling is to assess the condition of the shrimp. The observations from sampling serve as a basis for making decisions related to shrimp farming treatments. For instance, if signs of disease are detected, the farmers can promptly take mitigation measures after identifying the issue through sampling.

2. Evaluating Shrimp Uniformity

Shrimp populations are considered good when the size and weight are relatively uniform. To determine this, sampling can be carried out at a specific age of the shrimp, and then the weight and size uniformity can be observed. Knowing the uniformity helps farmers plan the appropriate feed management.

3. Calculating the Survival Rate

Shrimp sampling is also useful for calculating the survival rate (SR) over a specific period. The survival rate is determined by dividing the shrimp biomass by the initial number of post-larvae stocked and then multiplying it by 100%.

4. Calculating Average Body Weight

The average body weight (ABW) is the average weight of shrimp in a population during a specific period. ABW is calculated by dividing the total weight of the sampled shrimp by the number of shrimp collected.

5. Calculating Shrimp Biomass

Biomass refers to the total weight of shrimp in a population during a specific period, expressed in weight units. Shrimp biomass can be estimated by multiplying the survival rate (SR) with the initial population and then multiplying it by the ABW at a specific time.

6. Measuring Shrimp Size

Sampling is also used as a basis for measuring shrimp size. Shrimp size can be determined by counting the number of shrimp per 1 kg. For example, if there are 90 shrimp in 1 kg, it is referred to as “size 90.”

7. Assessing Pond Bottom Conditions

Sampling can also be beneficial for assessing the condition of the pond bottom. This can be done by observing the sediment brought up when casting the net in the pond for sampling. Observations are made to determine if there are shrimp deaths within acceptable limits.

Types of Shrimp Sampling in Shrimp Farming

1. Larvae Sampling

Larvae sampling is conducted to estimate the population size and quality of shrimp post-larvae that will be stocked into the ponds. This is done by randomly collecting a sample of larvae and transferring them to a container for further evaluation. The larvae can be observed under a microscope, undergo stress tests, activity tests, and their numbers are counted.

2. Corner Pond Sampling (Anco)

Corner pond sampling is done with the help of corner nets in each pond. The corner nets are useful for capturing small-sized shrimp. Typically, anco sampling is conducted when the shrimp have reached 25-35 days of age and are not too large.

3. Net Sampling

The last type of sampling in shrimp farming is net sampling. As the name suggests, this sampling method involves using a net to capture shrimp from the pond. Net sampling is usually carried out when the shrimp have reached a relatively larger size (2.5 grams) or at around 30 days after stocking.

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.

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

budidaya udang vaname — Source: DELOS Documentation

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

vannamei shrimp cultivation — Source: DELOS Documentation

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.

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.

Disease

Recognize the Symptoms of IHHNV Disease in Vannamei Shrimp and How to Prevent It

IHHNV, or Infectious Hypodermal and Hematopoietic Necrosis Virus, is a disease caused by a viral infection that attacks vannamei shrimp. This disease can cause shrimp to become stunted and deformed in some body parts.

IHHNV disease can attack all stages of shrimp life, from eggs, larvae, postlarvae, and juveniles to adult shrimp. Therefore, you must be careful and mitigate if you encounter shrimp with IHHNV symptoms.

However, you don’t need to worry; read more about the symptoms and how to prevent IHHNV in this article!

Symptoms of IHHNV Disease in Vannamei Shrimp:

IHHNV disease infects the hypodermal and hematopoietic tissues of vannamei shrimp, such as gills, cuticle epithelium, connective tissue, lymphoid organs, and others. Symptoms can vary depending on the severity of the infection. Some of the common symptoms of IHHNV in vannamei shrimp include:

1. Decreased Appetite

Vannamei shrimp infected with IHHNV showed a decrease in appetite. This can lead to slower growth rates and poor shrimp survival rates.

2. Discoloration and Deformity of the Body

Shrimp infected with IHHNV can show discoloration and deformities, namely stunting in some parts of the body and deformity of the rostrum. In acute conditions, the shrimp skin will appear pale white, the body’s surface will be overgrown with bacteria or fungi, and necrosis is seen in the cuticles, nerves, and antennae.

How to Prevent IHHNV in Vannamei Shrimp

There are several mitigation strategies that you can use to reduce the impact of IHHNV on the vannamei shrimp population in your pond, namely:

1. Implementation of Strict Biosecurity

Implementing strict biosecurity such as disinfecting ponds, water, and equipment, limiting interactions between people from outside the pond and the pond, and using disease-free broodstock and juveniles.

2. Do Early Detection and Treatment

Monitoring the condition of shrimp every day regularly can help you detect symptoms of IHHNV disease so that mitigation and treatment can be carried out immediately to reduce losses. Molecular disease checks using polymerase chain reaction (PCR), carried out regularly before stocking or during the cultivation process, are also very helpful in the early detection of IHHNV disease.

3. Implement Good Water Quality Management

Maintaining optimal water quality parameters with good management can also help you reduce stress on vannamei shrimp so that the shrimp are not susceptible to disease.

4. Select Disease Resistant Parent

Choosing parents who are genetically resistant to disease can help reduce the risk of infection in their offspring, including infection with IHHNV. The reason is that, in some cases, broodstock shrimp can reduce the disease in the fry produced.

5. Practice Good Feed Management

Good feed management will significantly help shrimp to meet their energy needs. Shrimp whose energy needs are met adequately will be more resistant to environmental stress and disease infection and grow faster.

6. Administer Immunostimulants and Feed Additives

Immunostimulants and feed additives, such as β-glucans, probiotics, vitamins, and others, can also improve the shrimp’s immune system to resist environmental stress and viral infections.
