How to Make Shrimp Farming More Resilient to Climate Change

Creating shrimp farming that is more resilient to climate change is crucial to maintaining high productivity. Especially since many shrimp ponds rely heavily on environmental conditions, particularly the availability of clean water at stable temperatures.

Fluctuating climates significantly impact shrimp farming, especially regarding water temperature, changes in rainfall patterns, and the potential for storms. While the effects of climate change are highly unpredictable, adaptation measures must be implemented by farmers to ensure their shrimp farming becomes more resilient to these changes.

Adapted from the writings of Kyra Hoevenaars and Jonah van Beijnen, here are some tips you can follow to make shrimp farming more resilient to climate.

Tips For Making Shrimp Farming More Resilient to Climate Change

1. Implement Good Farming Management

Implementing good shrimp farming management is the first step in addressing climate change, especially concerning the location of shrimp farming, ensuring appropriate stocking densities, and ensuring the biosecurity of your shrimp ponds.

Vulnerability to diseases is likely to increase with climate change because shrimp immune systems can be compromised when experiencing stress due to significant environmental changes in relatively short periods. By implementing good shrimp farming management, vulnerability to climate change-induced diseases can be prevented and mitigated.

2. Conduct Risk-Based Analysis

If you’ve just opened a new shrimp farming area, risk-based analysis should be conducted regarding climate change and other extreme weather events. This can also be applied to existing shrimp ponds. Analysis can be performed by examining climate change risks, potential impacts, and risk mitigation capacities.

If after conducting risk-based analysis problems cannot be addressed, relocating ponds to safer areas should be considered. Typically, this issue is faced by areas prone to drought and flooding.

3. Product Diversification

Product diversification is a common strategy used to reduce risks of losses due to climate change. This allows production to continue if one type of farming fails.

Diversification only works if different species are not subject to the same risks, such as specific disease outbreaks. Economically, diversification also makes farmers’ income sources more varied, stabilizing production and potentially increasing resource efficiency.

Additionally, market diversification between local, national, and international options is also important.

4. Utilize Early Warning Systems

Farmers should be familiar with climate change information and climate variations from reliable sources. Obtaining timely information or even earlier can allow farmers to respond more quickly to potential risks.

For example, understanding weather forecasts from the Meteorology, Climatology, and Geophysics Agency (BMKG). Through this, you can prepare for upcoming extreme weather, so you know what treatments your ponds will need next.

5. Improve Pond Infrastructure

To make shrimp farming more resilient to climate change, you need to improve your shrimp pond infrastructure. For example, by building higher and stronger embankments to protect against floods or creating deeper ponds in preparation for the dry season.

During the rainy season, it is important to ensure that your ponds can drain water out properly. For this, it is important to ensure that pipes and channels for water inflow and outflow, as well as drainage, work properly.

Moreover, ensure that the water channels are wide enough to accommodate extra water during heavy rains and floods. While during the dry season, these channels can be useful for ensuring the supply of water from the sea or rivers to the ponds.

6. Collaborate with Others

Most climate adaptation measures cannot be implemented by individuals alone. Therefore, farmers need to collaborate to achieve a common goal of productive and climate-resilient farming.

Through this organization, the exchange of knowledge and experiences can become stronger. Furthermore, access to information and existing resources. Taking collective responsibility in adapting to climate change is an important step in building farming that is more resilient to climate change.

Also Read: 3 Family Favorite Sweet and Sour Shrimp Recipes

How to Process Shrimp So It’s Not Fishy

1. Get Fresh Shrimp

Before knowing how to process shrimp, you must first buy fresh shrimp of the highest quality. Choose shrimp with a firm texture and a distinctive aroma. Because this is a sign of good quality shrimp.

If you buy frozen shrimp, make sure the shrimp are stored in the freezer, packed tightly, and have no signs of damage to the packaging.

2. How to Clean Shrimp

If you buy frozen shrimp, before cleaning them, you must first defrost them. An easy way to thaw frozen shrimp can be done by placing the shrimp in a bowl of cold water for about 20 minutes.

Meanwhile, if the shrimp you buy are fresh, you can immediately clean them. Cleaning shrimp can be done by removing the head and legs of the shrimp.

Then use a sharp knife to make shallow cuts along the back of the prawns, then remove the veins. After that, rinse the shrimp thoroughly with clean water and drain.

3. How to Peel the Shrimp

After removing the legs and head and cleaning the shrimp veins, the next step is peeling the shrimp skin. You can start by holding the shrimp’s body and carefully pulling the shell, so the shrimp meat doesn’t get crushed.

However, if you like shrimp with the shell on, you can skip this step and leave the shell on the shrimp.

4. Add Lime Juice

Just like seafood in general, shrimp also has a distinctive fishy smell. Therefore, how to process shrimp, so they are not fishy can be done by adding lime juice which can help disguise the fishy smell.

When adding the lime juice, don’t forget to let it rest for 10 to 15 minutes so that the fishy smell of the shrimp completely disappears.

5. Don’t Cook Shrimp for Too Long

After the shrimp are cleaned perfectly, the following way to process the shrimp is to ensure that the shrimp are not overcooked or cooked too long. This is because cooking shrimp for too long can remove the nutrients and make the shrimp meat tough.

What Is MBW Term In Shrimp Farming and How To Calculate It?

In shrimp farming, there are many important terms that farmers must know, one of them is MBW or Mean Body Weight. The term MBW refers to the average weight of vannamei shrimp per head resulting from sampling in a certain period.

MBW term in shrimp farming plays an important role during the cultivation period. It is because MBW is also used to calculate various other aspects of growth in shrimp. For example, to calculate ADG (average daily growth) and biomass of the vannamei shrimp.

So, how to calculate the MBW of vannamei shrimp? Let’s get to know about it in this article!

What is MBW Term in Shrimp Farming?

mbw in shrimp farming — Source: DELOS Documentation

If you have been in the aquaculture industry for a long time, especially shrimp farming, you might know there are many unique terms which generally abbreviated. Starting from ABW, MBW, FCR, SR, and many more.

The term MBW comes from the mean body weight, which means the average weight. In shrimp farming, MBW is the average weight of shrimp per head obtained from routine sampling during cultivation.

The purpose of doing this MBW calculation is to determine the condition and growth of shrimp. In addition, if certain diseases attack the shrimp, it can also be known from the sampling carried out regularly by looking at the anomalies of its growth.

In addition, if there is an anomaly in the growth of shrimp or even if the shrimp is infected with diseases, it can also be identified through abnormal MBW conditions as an early detection before further lab research is carried out.

How to Calculate MBW of Shrimp?

How to calculate the MBW of shrimp is quite easy to do; the first step is to take a random sampling of shrimp at several anchor points in the same pond map. The shrimp that were successfully taken were then weighed and counted.

After calculating each weight and number of shrimp in the sampling, you can use a special formula, namely by dividing the total weight of the shrimp by the total number of shrimp weighed.

Simply put, the shrimp MBW formula is as follows:

Isn’t it easy to calculate the MBW of shrimp? However, keep in mind that sampling must be done in the same place on each pond plot. This aims to obtain more accurate results in measuring the growth of shrimp.

Water Quality

Understanding the Types of Plankton in Shrimp Ponds

The presence of various types of plankton in shrimp ponds is quite diverse. Despite being microscopic in size, plankton plays a significant role and has a substantial influence on the shrimp pond ecosystem. Therefore, their presence must be constantly controlled.

The diversity of plankton in shrimp ponds indicates a stable and favourable pond environment. However, it’s important to remember that not all plankton have a positive impact on the pond ecosystem and shrimp growth.

This article will discuss what plankton is, the various types of plankton found in shrimp ponds and their impact on water quality, as well as which types of plankton can benefit or harm shrimp ponds.

What Is Plankton?

Plankton is a collection of small organisms that float or drift in water. They generally cannot actively move against water currents and rely on water movements to change their position.

Plankton is divided into two main groups: zooplankton (animal plankton) and phytoplankton (plant plankton). Both play important roles in the aquatic ecosystem of shrimp ponds, including serving as a natural food source for shrimp.

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

Types of Plankton in Shrimp Ponds and Their Effects on Water

a. Phytoplankton

Phytoplankton is a group of plankton consisting of microalgae and cyanobacteria. They play a role in oxygen production through photosynthesis and provide a food source for zooplankton.

However, uncontrolled phytoplankton growth can lead to issues in shrimp ponds. Excessive phytoplankton growth can cause a decrease in dissolved oxygen in the water (hypoxia) and affect water quality. This can be detrimental to shrimp as they require sufficiently oxygenated water to breathe.

b. Zooplankton

Zooplankton consists of various microscopic animals such as copepods, rotifers, and bivalve larvae. They serve as a natural shrimp feed source in shrimp ponds.

Adequate zooplankton populations in shrimp ponds can enhance shrimp growth and health. However, a population of zooplankton that is too low can lead to competition for food and slow shrimp growth.

Also Read: The Influence of Ion Composition on the Growth and Survival of Vannamei Shrimp

Beneficial Plankton Types for Shrimp Ponds

Some types of plankton that benefit shrimp ponds include:

a. Green Algae (Chlorophyta)

Chlorophyta, also known as green algae, are commonly found in shrimp ponds because they can thrive in various environmental conditions. Chlorophyta produce a light green to green colour in the water.

As the name suggests, Chlorophyta produces chlorophyll, which is beneficial for photosynthesis and provides additional oxygen in the pond, serving as a natural food source for shrimp.

b. Diatoms

Diatoms, also known as Bacilliariophyceae, are a crucial phytoplankton type that serves as a significant food source for shrimp. They contain nutrients such as omega-3 fatty acids that support the healthy growth of shrimp.

Harmful Plankton Types for Shrimp Ponds

Some types of plankton that can harm shrimp ponds include:

a. Cyanophyta

Cyanophyta, or blue-green algae, are plankton that can turn water green or even blackish. They can produce toxins that can poison shrimp in the pond and lead to toxic blooms, which can be highly detrimental to aquaculture.

b. Dinoflagellata

Toxic dinoflagellates can produce toxins from their flagella, which can be harmful and even fatal to shrimp. They can also disrupt water quality by releasing waste that causes water discolouration. Therefore, the presence of dinoflagellates in the pond should not exceed 5%.

Tips for Choosing and Determining the Number of Shrimp Pond Aerators

Shrimp pond aerators are one of the essential equipment in intensive and super-intensive aquaculture. These aerators, also known as aerators, are useful for maintaining dissolved oxygen (DO) levels within the optimal range.

Additionally, aerators serve several other functions, such as stratifying DO concentrations in ponds, regulating sediment deposition, stabilizing water currents in ponds, maximizing feed distribution areas, and minimizing dead spots in ponds.

The presence of shrimp pond aerators is crucial, so you need to ensure you have chosen good quality aerators and installed them in the right quantity in your vannamei shrimp ponds. Find out more tips in this article!

Also Read: How to Easily Calculate Vannamei Shrimp Size

Tips for Choosing Shrimp Pond Aerators

1. Ensure the Quality of Shrimp Pond Aerators

Currently, many domestic and international aerator factories offer high-quality aerators at affordable prices. Aquaculturists can conduct small research to compare the quality and prices of each aerator factory available. By conducting this research, aquaculturists can obtain the necessary information to make the right decision in choosing aerators that suit their needs.

2. Pay Attention to Aerator Power

The oxygen requirements in each pond can vary depending on several factors, such as stocking density, pond area, and shrimp growth stage (Day of Culture/DoC). Ponds with high stocking densities require more aerators than ponds with lower stocking densities. The size of the aerator should also be adjusted to the pond area to ensure sufficient oxygen distribution. The same applies to the shrimp growth stage.

In the initial stage, when the shrimp are still in the larval stage, fewer aerators may be needed compared to when the shrimp have grown larger. It is important to ensure that the selected aerators can effectively increase oxygen levels and distribute them evenly throughout the pond. As a guide, an aerator with a 1 Horse Power (HP) rating is considered ideal for supplying oxygen for every 500 kg of shrimp. Furthermore, to determine the number of aerators required, the total biomass of shrimp needs to be estimated first.

3. Choose Rust-Resistant Aerators

Shrimp pond aerators are often exposed to water directly, requiring sturdy construction and materials. The main component that is very vital is the dynamo or engine part. Therefore, it is advisable to ensure that this part has good resistance to water exposure and is not prone to rust.

4. Ensure Aerators Have Easily Accessible Spare Parts

When selecting shrimp pond aerators, it is important to ensure that their spare parts are easily accessible. Thus, if there are any problems or damage to the aerators, you can immediately complete the necessary repairs and maintenance.

Determining the Number of Required Aerators

To determine the number of shrimp pond aerators required, you need to consider several factors such as the available pond area, shrimp stocking density, available water resources, and proper shrimp pond management. Here are the steps you can follow:

1. Calculate Pond Area

The first step in determining the number of aerators needed for shrimp cultivation is by calculating the pond area. This is because not all ponds are the same size. Make sure you also measure the size of the aerators to fit the pond area you have.

2. Calculate Shrimp Stocking Density

The vannamei shrimp stocking density is also one of the factors that determine the number of shrimp pond aerators you need. The higher the stocking density, the more aerators are required. This is to ensure that the amount of oxygen received by the shrimp remains sufficient even when cultivated at high stocking densities.

3. Determine the Number of Aerators

After knowing the pond area and shrimp stocking density, you can then determine the number of shrimp pond aerators needed. Calculate the number of aerators required based on the pond area and aerator size. Make sure each area of the pond receives sufficient aeration to support healthy shrimp growth.

The Influence of Feed Quantity on the Growth Rate of Vannamei Shrimp

The influence of feed quantity on the growth rate of vannamei shrimp depends on how the feed management for vannamei shrimp is implemented. The amount of feed given to shrimp in ponds will relatively decrease as the shrimp grow. Therefore, giving the appropriate amount of feed will maximize the growth rate of the cultivated shrimp.

Feed for vannamei shrimp is a significant factor in aquaculture, especially in intensive and super-intensive systems. Additionally, feed accounts for up to 70% of the total costs incurred during cultivation. Therefore, to maximize the growth rate of vannamei shrimp, farmers must implement proper feed management.

Also Read: How to Increase the Appetite of Vannamei Shrimp

The Influence of Feed Quantity on Growth Rate

The amount of feed given to vannamei shrimp daily must match the shrimp’s needs in the pond, including nutrition, quantity, and frequency. Indeed, the shrimp growth rate can be influenced by internal factors such as genetics and external factors like nutrition in the feed, stocking density, and pond water environment.

Proper feeding can increase shrimp growth rates, leading to increased average shrimp body weight (ABW). Conversely, underfeeding can result in suboptimal shrimp growth, which in the long run affects the harvest yield.

How to Easily Calculate Vannamei Shrimp Size

Vannamei shrimp size is one of the crucial parameters for determining the success of cultivation. Usually, there is a target size to be achieved for certain post-larval shrimp stages. Therefore, farmers must know how to calculate shrimp size accurately.

Knowing how to calculate vannamei shrimp size accurately can provide many benefits for farmers. This includes feed planning, determining selling prices at harvest, and assessing whether shrimp cultivation is being done correctly.

For those who are not familiar with vannamei shrimp size, here is a summary for you.

Also Read: Understanding the Term “Anti-Dumping” in Shrimp Export

What is Vannamei Shrimp Size?

Size in shrimp cultivation is one of the indicators of successful farming. By knowing the size of the shrimp, you can determine the profit you will get in one cycle because size also determines the selling price to suppliers.

Vannamei shrimp size is a measurement system based on the number of shrimp per kilogram. The smaller the size number, the heavier and larger the shrimp produced. For example, a size 20 shrimp means there are 20 shrimp per kilogram.

Usually, during cultivation, shrimp with a size of 100 already have a market value, so partial harvesting is done. Subsequently, farmers can harvest when the shrimp reach size 90, size 50, and so on.

Calculating vannamei shrimp size is not difficult to understand. Usually, shrimp size is measured periodically during cultivation at certain post-larval stages and at harvest. Both are done using sampling methods.

After taking several shrimp for sampling using a scoop net or net, you can calculate the size using the formula:

For example, if sampling is done at post-larval stage 50 and the average body weight of shrimp obtained is 15 grams. Then, the size calculation is as follows:

Size = 1000 grams / 15 grams = 66.67

So, the calculated shrimp size is 66.67 shrimp/kg.

Tips to Achieve Optimal Shrimp Size

1. Ensure Water Quality Remains Optimal

The first tip to achieve optimal shrimp size is to ensure that all water quality parameters are always within the optimal range. Poor water quality can hinder shrimp growth. Moreover, sudden changes in water quality can stress the shrimp.

2. Choose High-Quality Post-Larvae

In essence, selecting high-quality post-larvae is the key to successful vannamei shrimp farming, including achieving optimal shrimp size. Incorrect selection and uncertified post-larvae can result in slow growth or increased susceptibility to diseases, making it difficult to achieve optimal size.

Furthermore, improper post-larvae stocking can lead to suboptimal shrimp growth. For example, excessive exposure to direct sunlight, stocking post-larvae without prior acclimatization, neglecting water quality, and overstocking.

3. Implement Best Operational Management

Implementing good operational management of shrimp ponds can also be a factor in achieving optimal shrimp size or not. Operational management includes feed management, water quality management, and daily shrimp maintenance.

4. Ensure Shrimp Nutrition is Met

When conducting intensive to super-intensive vannamei shrimp farming, providing feed and other supporting nutrition is crucial for optimal shrimp growth. Make sure to provide feed suitable for shrimp age, both in terms of nutrient composition and quantity.

5. Conduct Regular Sampling

To monitor the growth of your shrimp size and determine whether your shrimp are growing optimally, you need to conduct regular sampling. This sampling is very useful for checking the overall condition of your shrimp, including their health.

Function of Anco Shrimp Pond and How to Use It

Anco shrimp pond is a type of pond equipment that must be present in every shrimp pond. This tool is useful for monitoring the condition of shrimp through sampling, including in terms of feeding and monitoring the health conditions of the shrimp.

Anco is usually made of circular or square-shaped netting. This shrimp pond equipment is usually installed on each side of the pond, while the number varies according to the size of the pond.

Now, how do you use anco? Find out more in this article!

What is Anco Shrimp Pond?

Anco is shrimp pond equipment useful for sampling, both for controlling feed and shrimp health. Usually, anco is checked every day to detect anomalies, so that special treatments can be given immediately.

Anco are usually made of nets with various shapes and sizes. These shapes and sizes are adjusted to the needs of each pond. Typically, the size of anco ranges from 80 cm to 100 cm.

For vannamei shrimp ponds with an area of less than 0.4 hectares, the recommended number of ancos is between 2-4. Shrimp ponds with an area between 0.4-0.5 hectares should use 4 ancos. Shrimp ponds with an area between 0.6-0.7 hectares should use 5 ancos. And shrimp ponds with an area of 0.8-1 hectare should use 8-10 ancos.

Functions of Anco

1. Monitoring the Efficiency of Shrimp Feed Usage

The first function of anco is to monitor the efficiency of shrimp feed usage. Feed efficiency can be observed when the amount of feed given matches the needs of the shrimp for optimal growth. Therefore, shrimp farmers should not overfeed or underfeed.

You can adjust the amount of feed based on the age and estimated average weight of the shrimp. It is advisable to regularly check whether your shrimp are consuming the feed properly or not. This checking is usually done using anco.

2. Monitoring Shrimp Health

The next function of anco is to monitor the health of shrimp in the pond. You can sample by taking shrimp from anco and routinely checking their health conditions so that if anomalies occur, action can be taken promptly.

3. Sampling Shrimp Conditions

Routine sampling of shrimp conditions is usually also done with the help of anco in each pond. Anco, in this case, facilitates the retrieval of shrimp.

How to Install and Use Anco in Ponds

To install anco in shrimp ponds, you can follow these steps:

Prepare the anco and evenly spread the feed inside it.
Slowly submerge the anco into the pond water.
Wait for a moment until the shrimp consume the scattered feed.
Lift the anco carefully and check for remaining feed and shrimp reactions to the feed.
After installing the anco in the shrimp pond, you can start sampling to determine the shrimp feed consumption rate.
