5 Important Aspects in Vannamei Shrimp Farming that Must Be Known

important aspects in vannamei shrimp farming
Important Aspects in Vannamei Shrimp Farming

Before engaging in shrimp farming, farmers must be aware of the crucial aspects of Vannamei shrimp cultivation. This is essential to ensure that the farming activities proceed smoothly and yield satisfactory harvests. Considering that shrimp is one of the vital commodities in the fisheries industry, it becomes imperative to understand these aspects thoroughly.

The Ministry of Maritime Affairs and Fisheries has set ambitious targets regarding Vannamei shrimp production, aiming to reach 2 million tons by 2024. Achieving this goal requires collaboration from various parties, including the government and shrimp farmers. The following are the crucial points that should be considered in Vannamei shrimp farming:

Important Aspects in Vannamei Shrimp Farming

1. Availability of Water Source

One of the crucial aspects in Vannamei shrimp farming is the presence of a good water source. Vannamei shrimp require good water quality for optimal growth. Ensure that the pond water is free from contaminants such as industrial waste, agricultural waste, pathogens, and carriers of pests that can harm shrimp’s health.

Additionally, it’s important for farmers to routinely monitor water quality parameters daily. Optimal water quality conditions can promote optimal shrimp growth.

2. Type of Pond

When planning to construct shrimp ponds, it’s important to consider the type of pond that suits the budget and project objectives. There are four different types of ponds in terms of technology: extensive ponds (traditional), semi-intensive, intensive, and super-intensive.

Extensive ponds are known for low stocking densities, hence they tend to have lower productivity. However, they are easier to maintain compared to other types of ponds, resulting in lower risks of shrimp diseases. Typically, stocking densities in extensive ponds are <50 shrimp/m2.

On the other hand, semi-intensive ponds have higher stocking densities than extensive ponds, but are not as densely stocked, typically around <100 shrimp/m2.

Intensive ponds generally use direct earthen ponds but can be equipped with liners to reduce soil erosion. Intensive pond depths are also deeper than 1 meter to allow shrimp to move freely. Stocking densities in intensive ponds are >100 shrimp/m2.

Super-intensive ponds have even higher stocking densities, >200 shrimp/m2. However, this type of pond requires considerable investment due to the higher oxygen demand, necessitating more oxygen supply equipment. The depth of intensive ponds should also be increased to around 2.6 meters to prevent overcrowding of shrimp.

3. Selection of Postlarvae (PL)

The selection of postlarvae (PL) is crucial in Vannamei shrimp farming and should be carefully considered. The PL to be stocked should be healthy and free from diseases. Therefore, the PL must undergo a series of tests to ensure their health.

Before stocking, the PL should be in a stress-free condition after the shipping process. During transportation, the PL will be anesthetized and needs to recover before stocking. The recovery process can be done by gently swirling the PL bags. PL that are in good condition will swim against the current, while stressed PL will follow the current. Stressed PL should not be stocked immediately to reduce mortality rates.

The transportation of PL from the hatchery to the ponds poses its own challenges. PL must have sufficient oxygen supply during transportation to remain alive and reduce stress due to shipping.

4. Feed Selection

Choosing the right feed with appropriate nutrition is important in Vannamei shrimp farming and should be considered by all farmers. Various types of feeds are available for Vannamei shrimp farming, ranging from natural feeds to artificial feeds.

Ensure that the feed you choose has a balanced nutrient content suitable for the shrimp’s growth at each stage. Additionally, the amount and frequency of feeding should be well-regulated to avoid overfeeding or underfeeding.

5. Farm Management During Farming

Effective pond management is crucial to achieve optimal harvest results. This includes routine monitoring of pond environmental conditions, disease and predator control, feed management, and maintenance of pond infrastructure. Additionally, a risk management plan should be developed to anticipate potential issues that may arise during shrimp farming.

When buying shrimp, several things need to be considered to determine whether the shrimp are fresh. The shrimp’s color, texture, smell, and physical condition are the leading indicators that need attention.

By understanding the characteristics of fresh shrimp, you can make the right decision before buying it. This is to ensure you get the highest quality shrimp while ensuring it is healthy and safe.

So, what characteristics should you know of fresh shrimp before buying them? Read more in this article.

Also Read: Causes and Ways to Overcome Stress in Vannamei Shrimp

Characteristics of Fresh Shrimp

1. Bright Color

The first and most important characteristic of fresh shrimp is the bright color of the shrimp’s body. This is because the color of the shrimp is directly related to its freshness. Fresh shrimp usually have a clear pink or grayish color.

2. Hard Textured

The texture is hard and slightly chewy, another characteristic of fresh shrimp that you can use as a benchmark. The surface of fresh shrimp should be firm and not slimy. If the shrimp are slimy or mushy, they may not be fresh or have gone bad.

3. Mild Smell

The following characteristic of fresh shrimp is that it has a light fishy smell. If the prawns have a strong fishy odor, this is an indication that they are not fresh. So make sure the fishy smell of the shrimp you choose is manageable.

4. Clear Eyes

Fresh shrimp have clear, bright eyes without any cloudiness or discoloration. The eyes of the prawns are a good indicator of freshness as they tend to get cloudy if the prawns sit too long after harvesting. If the shrimp’s eyes are gray or damaged, this could indicate that the shrimp is no longer fresh.

5. Intact Shell

The next characteristic of fresh shrimp is that they have intact shells and show no signs of cracks or damage. Freshly caught prawns have a shiny, smooth shells. If the shrimp’s shell is cracked or damaged, the shrimp is not fresh.

6. Tight Tail

Shrimp tails are tight and tightly curled, indicating freshness. If you get prawns with loose tails, they may not be fresh anymore. Therefore, please pay attention to the shrimp tail before buying it.

7. No Black Spots

Fresh shrimp should not have any black spots on the body. These black spots indicate decay. If you find shrimp in the market or supermarket with black spots on the body, the shrimp is not fresh and has been exposed to bacteria.

8. Not Yellowing

Fresh shrimp tend to be transparent gray. If you find shrimp with a yellow body, this indicates that the shrimp is not fresh and indicates spoilage.

9. No Ammonia Odor

Fresh shrimp should not smell ammonia. This ammonia smell indicates that the shrimp is no longer fresh and starting to go bad. So please pay attention to how the shrimp smell before buying them.

10. Stored in the Right Place

The last characteristic of fresh shrimp is that they are stored in the right place in the refrigerator at a temperature of 0°C to 4°C to maintain their freshness and quality. Keeping shrimp at the right temperature can prevent bacterial growth and preserve their texture and taste.

Characteristics of Stale Shrimp

Aside from taste, stale shrimp can also have negative effects on the body when consumed. Here’s a more detailed explanation of the characteristics of stale shrimp!

1. Unpleasant Odor

The first characteristic of stale shrimp is the presence of an unpleasant odour. This odour is usually caused by bacterial growth or tissue damage in the shrimp’s body.

2. Change in Shrimp Color

Fresh shrimp have bright and transparent colours. If the shrimp’s colour starts to become cloudy, yellowish, or even greyish, this could be a sign that the shrimp is no longer fresh.

3. Soft Texture of Shrimp

When shrimp is no longer fresh, its texture will also change. Stale shrimp typically feel soft, and mushy, and have a slippery surface. This is caused by cell damage or physical changes due to shrimp spoilage.

4. Slimy Shrimp Skin

Slimy shrimp skin can indicate that the shrimp is no longer fresh. This slime is formed due to bacterial or fungal growth on the surface of the shrimp’s skin, which has started to deteriorate.

5. Appearance of Black Spots

The appearance of black spots on the shrimp’s skin is another characteristic of stale shrimp. These black spots are caused by bacteria that have entered the shrimp’s body, causing it to spoil and also indicating poor storage conditions.

Tips for Choosing Fresh Shrimp

To ensure you’re selecting fresh shrimp when shopping, you can follow these tips:

1. Check the Color and Aroma of the Shrimp

When choosing fresh shrimp, pay attention to its colour and aroma. Fresh shrimp usually have bright colours. A dull or pale colour could indicate that the shrimp is not fresh. Additionally, the aroma of fresh shrimp is a fresh and distinctive seafood scent. Avoid shrimp that emit an unpleasant or fishy odour, as this could indicate that the shrimp has been stored for a long time or contaminated by bacteria.

2. Examine the Texture of the Shrimp

One way to check the freshness of shrimp is by touching or pressing it directly. Fresh shrimp will feel firm and slightly resilient to the touch. When pressed, fresh shrimp retain their shape and not easily crushed. However, stale shrimp will feel soft and release water when pressed. This could be a sign that the shrimp is not in its best condition.

3. Observe the Adhesion of the Body

When selecting shrimp, also observe the adhesion of its skin to the body. In fresh shrimp, the skin usually adheres tightly to the flesh and is transparent or clear in colour. Avoid shrimp with loose or peeling skin, as this could indicate that the shrimp is not fresh or may have been damaged. Additionally, make sure that the shrimp’s head is still attached to its body, as this is also an indicator of its freshness.

Water Quality

The Use of Dolomite Lime in Shrimp Farming: Benefits and Implementation

dolomite lime
Source: DELOS Documentation

Shrimp farming has become an increasingly important industry in the aquaculture sector. To achieve optimal results, environmental factors affecting shrimp well-being must be carefully managed. The application of dolomite lime is one common treatment done to support pond productivity.

Dolomite lime becomes one important aspect of shrimp farming is maintaining proper water quality and pH. Various types of lime, including dolomite lime, play a significant role in this regard. Let’s explore further!

What Is Dolomite Lime?

Also known as calcium magnesium carbonate or CaMg(CO3)2, dolomite differs significantly from agricultural lime. Dolomite is a pure substance rich in calcium and magnesium, whereas agricultural lime only contains calcium used to address soil acidity. The presence of dolomite is crucial for cultivation success, especially in shrimp farming.

Dolomite is produced through a process known as dolomitization, which has a composition similar to limestone or calcite. The use of lime in shrimp farming also helps to address issues related to alkalinity, pH stability, and the breakdown of organic matter in cultivation media.

Dolomitic lime has high levels of magnesium and calcium, which can address various issues including soil acidity, soil toxins, soil porosity, and nutrient availability. In contrast, agricultural lime only contains calcium used to address soil acidity.

Also Read: The Importance of Minerals in Vannamei Shrimp Farming

Benefits of Dolomite Lime in Shrimp Ponds

The acidity level, or pH, plays a crucial role in the physiological stability and metabolism of shrimp. The recommended pH range for water in shrimp farming is between 7.8 and 8.5. Therefore, shrimp farmers must continuously maintain the pH range of shrimp pond water to remain in optimal conditions. One way to do this is by adding dolomite lime when necessary.

Dolomitic lime primarily functions to increase pH in both water and soil. The lime works by binding hydrogen ions (H), thereby reducing the acidity levels in water and soil. Lime can be directly added to water, sprinkled onto soil, or mixed into shrimp feed. Here are the details:

1. Increasing Alkalinity

The first benefit of dolomite lime for shrimp ponds is increasing the alkalinity of ponds that fall below the optimal threshold. The pond water’s alkalinity should ideally range between 130-180 ppm as it significantly influences pH stability.

An increase in alkalinity impacts pH control and calcium concentration. Adequate alkalinity can maintain pH fluctuations between morning and afternoon within the range of 0.2 to 0.5. pH changes should not exceed 0.5. Drastic changes can cause shrimp to go into shock and stop eating.

2. pH Stabilization of Water

A critical aspect of shrimp farming is maintaining the right water pH. Significant pH fluctuations can disrupt the biological balance in the aquatic environment and negatively impact shrimp health. Dolomite lime can be used to counteract pH fluctuations by acting as a pH buffer. It can bind the acids present in the water and prevent sharp drops in pH.

3. Providing Calcium and Magnesium

Dolomite lime provides a source of essential calcium and magnesium for shrimp growth and development. Calcium is vital for forming strong shells and exoskeletons, while magnesium is required in various biochemical processes within the shrimp’s body.

4. Accelerating Molting Processes

Dolomite lime treatment will provide a source of calcium that shrimp need during the molting process. The more frequently shrimp moult, the faster their growth. To support this, an adequate supply of minerals, especially calcium, is crucial. Calcium plays a role in the formation and hardening of new shrimp shells.

Dolomite lime can be applied by spreading it directly into the water or mixing it into shrimp feed. If added to feed, lime will increase the mineral content of the feed as a source of calcium to facilitate the shrimp moulting process. Adjusting the calcium-to-phosphorus (Ca/P) ratio in feed also contributes to the health of shrimp shells and feed efficiency.

5. Improving Water Quality

The addition of dolomite lime to shrimp farming ponds can help control heavy metal levels and toxins in the water. This helps maintain optimal water quality, which, in turn, supports shrimp growth and health.

6. Accelerating the Organic Matter Decomposition Process

The primary benefit of dolomite lime for shrimp ponds is to accelerate the decomposition process of organic matter, especially for ponds with soil that tends to be acidic. Soil acidity disrupts vital nutrient cycles.

In shrimp ponds, soil often becomes more acidic due to the accumulation of organic matter from leftover feed and shrimp metabolic waste (feces). This can lead to decreased productivity and environmental degradation. The process of organic matter decomposition also becomes suboptimal.

The dolomite lime application also serves as a solution for ponds with excessively murky water, indicated by low water clarity, which is an indication of excessive algae growth (blooming algae). Lime helps increase sunlight penetration into the water, thereby improving water clarity. Lime binds phosphate from water, especially through its calcium content, which limits the photosynthesis process of phytoplankton. As a result, water pH increases and carbon dioxide concentration decreases.

7. Algae Control

Excessive algae growth can lead to a decrease in water quality and disrupt shrimp well-being. Dolomite lime can help control excessive algae growth by reducing the availability of nutrients needed by algae.

Implementation in Shrimp Farming

The use of dolomite lime in shrimp farming should be based on regular water quality analysis. The amount of dolomite lime needed will vary depending on water conditions, pond size, and the shrimp species being cultured. It is important to collaborate with aquaculture experts or consultants to determine the appropriate dosage.

Furthermore, the use of dolomite lime should be integrated with sustainable farming practices. Efforts such as proper feed management, regular monitoring of water parameters, and responsible waste management will support the effectiveness of dolomite lime in maintaining a healthy farming environment.
