Benefits of Ice in Preserving the Freshness of Vannamei Shrimp

To maintain the freshness of vannamei shrimp post-harvest until it reaches processing, ice is commonly used. The optimal ice ratio used is 1:1. However, this depends on the terrain and the duration of the shrimp’s journey to processing.

The use of ice with the right ratio helps in preserving the quality and nutrients in shrimp. As a result, consumers will receive optimal nutrition when consuming them. Here are five benefits of ice in preserving the freshness of shrimp:

1. Cooling the Shrimp

After harvest, shrimp must be cooled promptly to slow down the spoilage process. The use of ice plays a key role in maintaining the freshness of shrimp during transportation to processing. Properly cooled shrimp will remain fresh and of high quality.

2. Temperature Control

Shrimp quality is highly dependent on temperature, and ice serves as an effective cooling medium to maintain optimal temperature during transportation, ensuring the freshness of shrimp.

3. Preserving Shrimp Texture

Inadequate post-harvest temperature and handling can alter the texture of shrimp. Ice can help preserve shrimp, ensuring consistent texture until it reaches processing for further treatment.

4. Preventing Physical Damage to Shrimp

Shaking and friction during the transportation of shrimp to processing can cause physical damage such as broken tails, heads, or damage to the carapace. Ice acts as a protective layer and shock absorber, reducing the risk of physical damage and maintaining shrimp quality.

5. Increasing the Shelf Life of Shrimp

Ice helps maintain the low temperatures necessary to preserve shrimp quality. By slowing down the spoilage process, ice also extends the shelf life of shrimp, allowing for longer-distance transportation without sacrificing quality.

What is Traceability in Shrimp Farming?

Traceability refers to the ability to track the origin and history of a product from the source to the end, including the entire production and distribution processes. In the context of shrimp farming, traceability helps to identify the resources used, the cultivation techniques applied, and the processing methods of each shrimp product. 

This includes everything from hatchery practices, feed used, and the use of medications, to the methods of product delivery to consumers.

The Importance of Traceability in Shrimp Farming

1. Food Safety

Traceability is crucial in ensuring food safety for consumers. With the ability to trace the history of shrimp products, authorities and consumers can verify whether shrimp have been produced under high food safety standards and whether there are any contamination risks or allergen concerns to be worried about.

2. Disease Management

The shrimp industry often faces the risk of disease outbreaks that can cause significant losses. Traceability enables farmers to track the source of the problem and identify the causes of the outbreak quickly. This way, preventive measures can be taken earlier to reduce its impact, such as isolating infected areas and using appropriate medications.

3. Resource Management

In order to maintain the sustainability of shrimp farming, it is essential to manage resources wisely. Traceability allows better monitoring and evaluation of water usage, feed, and chemicals. This data can help reduce waste and optimize the use of natural resources.

4. Compliance with Legal Requirements

Several countries have implemented strict regulations regarding food quality, safety, and production sustainability. Traceability systems help shrimp producers comply with these legal requirements by clearly documenting their farming practices.

5. Building Consumer Trust

In an era where consumers are increasingly concerned about the origin of the products they buy, traceability can be a crucial tool in building trust. Environmentally and socially conscious consumers are more likely to choose products with traceable production histories, knowing that the products were produced responsibly and ethically.

6. Crisis Management Capability

In the worst-case scenario, such as food scandals or shrimp-related health incidents, traceability enables producers to handle crises more effectively. With accurate data, companies can isolate the problem and take corrective actions in a timely manner.

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.

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.

5 Types of Shrimp Pond Aerators and Their Functions

A shrimp pond aerator is one of the main components in aquaculture, especially in intensive and super-intensive ponds. An aerator is a tool that serves to dissolve free oxygen into pond water.

The existence of a water wheel and other supporting equipment for shrimp growth in aquaculture is intended so that ponds can become a comfortable ecosystem for shrimp growth. So that shrimp can grow optimally.

Shrimp pond aerator functions to create aeration. Aeration is a process of increasing the oxygen content in the aquatic environment to ensure that the organisms that live in it get an adequate supply of oxygen and live healthily.

In this article, let’s discover the types of waterwheels commonly used in shrimp ponds and their functions!

Also Read: 4 Types of Vannamei Shrimp Harvest Time

The Function of the Shrimp Pond Aerator

  1. Increasing the supply of oxygen in the water stabilizes the biological processes of shrimp.
  2. Ensuring the shrimp get an adequate supply of dissolved oxygen
  3. Improve the quality of the water where shrimp live.
  4. Helps distribute nutrients and feed evenly into the pond.
  5. Make it easier for pond bottom manure to be directed to the disposal center so that the pond bottom is easier to clean.

Types of Pond Aerators

1. Pond Waterwheel with Paddle Wheel

In terms of performance, the paddle-wheel water wheel is the most effective aerator on the pond surface. The parts consist of a frame, motor, float, clutch, deceleration engine, bearings, and paddle wheel.

This waterwheel works by splashing water into the air and capturing oxygen to increase the DO content. The more bubbles produced, the more oxygen is captured.

2. Spiral Aerators

A spiral aerator is an improvised form of a paddle-wheel water wheel, the difference being the shape of the wheels. As the name suggests, this aerator wheel is spiral. In addition, there are several other differences, such as reducing the gearbox or reducer, handle, and connecting shaft.

Meanwhile, in terms of how it works, spiral aerators also sprinkle water into the air to capture oxygen. However, it gets many more bubbles than a regular paddle wheel waterwheel.

3. Pump Sprayer Aerator

A pump aerator is a type of aerator that works by drawing water into a vertical tube and then sprinkling it into the air to capture oxygen. The water will be deflected radially and then fall back to the surface in an umbrella-like pattern.

This type of aerator is widely chosen because it does not require much special care. However, its use can only reach a small area, while it needs to be optimal in large sizes.

In-use pump aerators are usually used in small ponds or can also be used in large ponds but in combination with other types of aerators.

4. Vertical Pump Aerator

A vertical pump aerator has the same working principle as a pump aerator, which is to draw water into the pump tube and then sprinkle it into the air.

Vertical pump aerators are more suitable for small ponds up to 0.25 Ha because the splash produced by this aerator is not as big as a waterwheel. Meanwhile, the capacity ranges from 1 kW to more than 50 kW.

5. Jet Aerators

The jet aerator consists of a shrimp pond water wheel composed of a frame, air suction pipe, propeller, and driving motor. Unlike other types of aerators, the propellers of this aerator are in the water.

The way it works starts with a propeller rotating in the water and sucking in air from outside the pool through a pipe. After the air is sucked in and enters the water, bubbles will appear, indicating that the oxygen supply is starting to enter.
