The Importance of Sea Level Altitude for Aquaculture

Shrimp cultivation is one of the industries that is growing rapidly in various countries in the world. One factor that determines this cultivation’s success is the sea level altitude.

However, the impact of recent climate change is rising sea levels. This change in sea level is visible and occasionally continues, extending to the vulnerable lowlands near the coast.

The consequences of rising sea levels are quite diverse, from the risk of major floods that can damage coastal areas to the impact on the fishing and aquaculture industries.

Directly, sea level altitude affects shrimp farming in several aspects, including water quality, salinity, and temperature. Here are some reasons why sea level is important for shrimp farming:

The Importance of Sea Level Altitude for Aquaculture

1. Water Quality

Water quality is one of the most important factors affecting the growth and survival of shrimp. The water quality of shrimp ponds is directly affected by sea level altitude.

Vannamei shrimp ponds usually use irrigation sources from the sea or estuaries. A higher sea level means more seawater enters the pond, indirectly obtaining water quality with high levels of dissolved oxygen and low pollution.

On the other hand, lower sea levels can cause stagnant water in ponds, which can lead to a buildup of harmful bacteria and algae, degrade water quality and cause disease outbreaks among shrimp. This can cause significant losses for shrimp farmers.

2. Salinity

Salinity is another factor that affects the growth and survival of shrimp. The optimal salinity level in vannamei shrimp ponds ranges from 15 to 25 parts per thousand (ppt).

Higher sea levels mean more seawater will enter the pond, increasing the water’s salinity level. Salinity that is too high can cause shrimp to become stressed, resulting in less than-optimal growth.

Conversely, lower sea levels can result in lower pond salinity levels, affecting shrimp growth and survival rates.

Therefore, farmers need to maintain the pond water salinity level always to be optimal.

3. Temperature

The temperature of the pond water is also affected by the sea level. Shrimp need an optimal temperature range of 28 to 32 degrees Celsius to thrive. Temperature fluctuations can also be affected by sea levels.

Higher sea levels can result in cooler water temperatures, which can slow down the growth rate of the shrimp. On the other hand, lower sea levels can cause higher water temperatures and can stress shrimp.

4. Disease Control

The sea level also plays an important role in controlling disease in vannamei shrimp farming. Higher sea level means more seawater entering the pond, which reduces the buildup of disease-causing bacteria and viruses.

Shrimp Farm Equipment for Water Installation

When vannamei shrimp ponds are built higher than sea level, these ponds will require pumps and supporting installations to drain the water. This is necessary to ensure the quality of pond water when cultivation is properly maintained and optimal.

Intensive to super-intensive scale shrimp ponds rely heavily on seawater as the main water source. Therefore it takes the role of pumps and other supporting installations such as pipes which play a crucial role.

At least the pipes and pumps used are made of materials resistant to corrosive seawater. The pipes must also be strong and resistant to coastal climate and weather conditions.

Vannamei Shrimp Stocking Density and How to Calculate It

One important aspect of aquaculture is determining the optimal vannamei shrimp stocking density. This can be done to consider the number of shrimp that can be accommodated from start to harvest in the pond that has been prepared.

Stocking density plays an important role in the success of aquaculture because excess density can cause poor water quality, disease attacks, and stunted shrimp growth in ponds.

In addition, shrimp stocking densities that are too high can also increase competition for food and space. So, what is the ideal stocking density for traditional, semi-intensive, intensive, and super-intensive ponds? Read more in this article.

Also Read: Vannamei Shrimp Salinity and How to Control Its Stability during Cultivation

Why is it Important to Consider Stocking Density?

Farmers must consider the stocking density of the vannamei shrimp they will choose before starting cultivation. This is because stocking density directly affects the growth and quality of the cultivated vannamei shrimp.

There are several other reasons why it is important to consider the stocking density, including:

1. Ensuring Optimal Shrimp Growth and Health

Traditional and intensive vannamei shrimp stocking densities significantly impact the growth and health of vannamei shrimp. Overcrowding can lead to poor water quality, increased competition for food and space, and increased risk of disease outbreaks.

Calculating the stocking density of vannamei shrimp and adjusting it to pond conditions ensures it can grow and develop optimally.

2. Maximizing Cultivation Results

Intensive vannamei shrimp stocking density is closely related to the cultivation results obtained later. The density that is too low in large ponds is the same as not utilizing available resources efficiently, so the yields are not optimal.

Conversely, a density that is too high and does not match the capacity of the pond can cause an increase in mortality and a decrease in growth rates. Therefore, by calculating the stocking density and adjusting it according to needs, farmers can maximize the potential of their ponds.

3. Cost Effectiveness

Vannamei shrimp cultivation is a lucrative business because the profits are very abundant. However, like business, this abundant profitability must be accompanied by cost-effective use during the cycle.

Calculating the stocking density of vannamei shrimp is one way to help cultivators determine capital and maximize their profits from this cultivation.

Too high density can lead to increased mortality, decreased growth rates, and increased FCR numbers. This will also impact increasing costs and reducing profits when the harvest arrives.

4. Disease Management

The density of vannamei shrimp directly affects the risk of disease outbreaks during cultivation. Pond ponds that are too dense can affect water quality, triggering disease outbreaks over time.

By calculating stocking densities and maintaining them at optimal levels, farmers can reduce the possibility of disease outbreaks and minimize the need for expensive shrimp health care.

5. Environmental Sustainability

Vannamei shrimp cultivation can cause significant environmental impacts, especially in intensive and super-intensive cultivation types that must be carried out sustainably.

The more shrimp cultivated in the pond, the more dirt and food scraps are produced during cultivation. Dirt and food scraps can turn into chemical compounds that harm the environment.

Therefore, by calculating the stocking density and maintaining it at an appropriate level, farmers can minimize the negative impact on the environment that may occur.

How to calculate the stocking density of Vannamei Shrimp

Calculating the stocking density of vannamei shrimp requires careful measurement and accurate recording. This is so that your cultivation can bring maximum profit and avoid losses.

Then, how to calculate the stocking density of vannamei shrimp? Here are the steps.

Calculate the Capacity of the Pond 

The first step you have to take is to calculate the pond capacity that will be used for vannamei shrimp cultivation. How to calculate the area of a vannamei shrimp pond can be measured using a measuring tape or other measuring device.

If the pond you have is rectangular, you can use the volume formula as follows:

Volume = pond length (meters) x pond width (meters) x pond depth (meters)

For example, if you have a pond with a length of 10 meters, a width of 5 meters, and a depth of 3 meters. Then the capacity of the pond = 10 x 5 x 3 = 150 cubic meters.

After knowing the capacity of your vannamei shrimp pond, choose a stocking density following this capacity.

However, if you already know the area of the pond that you have for sure, you can immediately follow the second step, namely calculating the stocking density of vannamei shrimp.

Calculate the Stocking Density of Vannamei Shrimp

Vannamei shrimp stocking density depends on the cultivation method used. For example, use traditional, semi-intensive, intensive, or super-intensive cultivation methods.

The formula for total stocking density = pond area (square meters) x stocking density per meter

This total stocking density is usually used for calculating the amount of feed, aerators, and other pond needs.

The stocking density of vannamei shrimp in traditional ponds is usually a little, which is around 5-8 PL per square meter. If your pond is 100 square meters in area, then 100 x 5 = 500 shrimp fry that can be stocked in the pond.

While in intensive ponds, the stocking density of vannamei shrimp tends to be higher. The stocking density of intensive ponds is above 100 per square meter. At the same time, the calculation formula must also be adjusted to the number of wheels and aerators used.

5 Tips on Managing Vannamei Shrimp Ponds

Success when cultivating always depends on our way of managing vannamei shrimp ponds. Both in terms of technical and non-technical factors. Therefore, farmers need to have good pond planning and management.

This method of managing shrimp ponds also directly affects harvest productivity. Thus, many factors must be considered in vannamei shrimp farming, such as human resource factors, feed management, shrimp health management, and the harvest process.

Here we have summarized some tips on managing shrimp ponds, especially for you, so that the harvests are as expected.

Also Read: These are 7 Tips for Successful and Profitable Vannamei Shrimp Harvest

Ideal Shrimp Pond

Talking about the ideal shrimp pond, the first thing that comes to your mind is how it is constructed. This is because construction has an important role in the sustainability of shrimp ponds.

So, here are the criteria for ideal shrimp ponds regulated in the Ministry of Maritime Affairs and Fisheries Regulation No. 75/PERMEN-KP/2016 concerning General Guidelines for Enlargement of Tiger Shrimp (Penaeus Monodon) and Vannamei Shrimp (Litopenaeus Vannamei).

  1. Have sufficient water availability.
  2. Ponds do not have dead spots.
  3. Effective and efficient in the use of land and mills.
  4. The bund as an access road in the pond must be passable by vehicles and workers.
  5. Guaranteed maximum security and safety (K3).

If you have fulfilled the five criteria based on the Minister of Maritime Affairs and Fisheries Regulation No. 75 of 2016 above, you can then select the ideal pond location. Some of the criteria for an ideal pond location include the following:

  1. The location of the shrimp ponds is under the Regional Spatial Plan (RTRW) and applicable regulations.
  2. The location of the new shrimp ponds above/behind the shoreline (100 meters from the highest tide point) and the riverbank.
  3. Having sufficient and good quality source water.
  4. Located in an area protected from routine flooding and the influence of toxic and hazardous waste (B3) pollution.
  5. Do not build new ponds on mangrove land and the core zone of the conservation area.
  6. Do not build shrimp ponds in areas where saltwater seepage has the potential to affect surrounding agricultural areas or freshwater sources.
  7. Adequate transportation and communication infrastructure is available.

Tips for Managing Shrimp Ponds

1. Choose the Right Pond Lining

The pond bottom lining is important to ensuring biosecurity during shrimp farming. Ground ponds directly exposed to water can trigger anoxic reactions, which are highly toxic to shrimp. Therefore, coatings such as high-density polyethylene (HDPE) plastic or concrete can be a solution.

In addition to biosecurity issues, using HDPE concrete and plastic layers also makes it easier to manage water and pond bottoms.

2. Consider Pond Design

The design of the vannamei shrimp pond has various shapes, including rectangular, square and round. This pond’s shape has advantages and disadvantages, as well as an effect on water flow and pond sediment accumulation.

While at the bottom of the pond can be designed with a central channel to minimize sedimentation. It works by utilizing the sedimentation and centrifugal currents generated by the aerator to push and concentrate the solids that settle in the middle of the pond.

Then, these solids can be manually pumped out of the pond through a pumping system connected to the sewer.

3. Place the Pond Aerator Properly

In intensive system vannamei shrimp farming, the aerator plays an important role in providing oxygen while helping to push sludge into the sewer. While the type and number of aerators can be adjusted to the needs of each pond based on pond size and stocking density.

To set up the aerator, you need to make sure that the aerator has covered all the corners and sides of the pond so that no mud remains untouched. There are two main designs for placing aerators: parallel and diagonal.

4. Clean the Pond Base Manually

The next tip for managing vannamei shrimp pond is routinely cleaning the pond’s bottom. Manual cleaning or suctioning of waste is good for maintaining optimal pond bottom quality.

So, how often should the bottom of the pond be cleaned? In general, there are no specific rules regarding how often to clean. However, it is recommended to do it once daily so that the waste that settles does not accumulate too much.

5. Periodic Basic Evaluation of Ponds

As the vannamei shrimp farming cycle progresses, it is very important to know the sediment condition at the bottom of the pond to prevent negative impacts. So it is necessary to evaluate periodically by taking sediment samples at certain points. The evaluation parameters include Redox potential, pH, pH2S, and NH4-N sol.

Sampling should be done regularly, at least twice per cycle. Precisely in the middle of the cultivation cycle when the mud begins to form and at the end of the cycle as an evaluation.

However, more frequent evaluations should be carried out in special cases such as mass mortality or slow growth of shrimp.

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

The threat of nitrite in shrimp ponds is an impact on the environment from intensive vannamei shrimp cultivation that all shrimp farmers can face. Therefore, farmers must find out ways to prevent and overcome them immediately.

Vannamei shrimp has long been a species of shrimp cultivated in Indonesia. This is because this type of shrimp is a food that is very popular with people around the world, so its export value continues to increase from year to year.

However, the intensive cultivation of vannamei shrimp can cause various impacts on the environment, one of which is the threat of nitrites. So, how to overcome it? Read more in this article!

Also Read: Get to Know Myo IMNV Disease in Vannamei Shrimp and Its Characteristics

What is Nitrite in Shrimp Ponds?

Nitrite in shrimp ponds is a toxic substance produced from nitrogen which is only partially oxidized. This substance is not found in fresh wastewater but in wastewater that has long been settling and accumulating.

High nitrite levels can result from overfeeding of shrimp, excessive sediment density, poor water circulation, and other factors that upset the balance of the nitrogen cycle.

Nitrite is very toxic to vannamei shrimp. Its presence can cause various adverse effects, including stunted growth and development of shrimp or even death.

Nitrite is not fixed and can turn into ammonia or be oxidized to nitrate at any time. When compared with nitrate, the presence of nitrite in the waters is less. However, the level of toxicity for vannamei shrimp is very high.

The danger of nitrite toxicity in vannamei shrimp ponds is especially evident in the early stages of the cultivation cycle. During this initial stage, nitrite levels can rise rapidly and reach dangerously toxic levels.

The presence of oxygen in shrimp ponds affects the presence of nitrites in shrimp ponds. In general, waters that get an adequate supply of oxygen have lower levels of nitrite concentration when compared to waters that do not get an oxygen supply.

How to Overcome Nitrite Threats in Shrimp Ponds

Even though it has a high level of toxicity, it does not mean that the nitrite threat cannot be overcome. One of the most important steps must be taken is monitoring water quality regularly and keeping other parameters optimal.

This can be done by adjusting the feeding, increasing oxygen circulation, and adjusting the stocking density of vannamei shrimp to prevent overcrowding.

How to deal with the threat of nitrite in shrimp ponds can also be done by adding nitrite-reducing bacteria into the pond. These bacteria can consume nitrites and convert them into less harmful substances, such as nitrogen gas.

Not only that, the presence of bacteria known as Nitrobacter can also help improve water quality along with reduced nitrite levels, making it safe for the growth of cultivated vannamei shrimp.

In addition, it is also essential to keep the pond well-aerated, especially in the early stages of the culture cycle. Adequate aeration helps ensure dissolved oxygen levels remain high, reducing the risk of nitrite toxicity and other water quality problems.

Vannamei Shrimp DOC 20, How is it Growing and How is the Feeding?

During cultivation, the growth of vannamei shrimp must constantly be monitored, including vannamei shrimp DOC 20. This is because this type of shrimp has a faster growth rate when compared to other kinds of shrimp.

For farmers, understanding growth patterns during vannamei shrimp cultivation are very important for successful cultivation. This is because the growth of vannamei shrimp also affects the feeding given to the shrimp.

So how is the growth of vannamei shrimp DOC 20, and how is the feeding? The following is an explanation we have summarized especially for you, which can be used as a reference.

Also Read: How to Cultivate Vannamei Shrimp from Preparation to Harvest

Vannamei Shrimp Growth DOC 20

Vannamei shrimp DOC 20, which is still at the beginning of cultivation, has an ideal growth rate of 1-2.5 grams per week. At the same time, the ideal weight is approximately 2 grams per head.

This ideal growth can be obtained if the number of shrimp populations in the pond is by its capacity. On the other hand, if the pond has excess capacity, the growth of the vannamei shrimp in it can be lower than the ideal growth average.

So, how do you cultivate vannamei shrimp DOC 20 or, more precisely during the early stages of cultivation? Like aquaculture in general, farmers must continue to control shrimp and pond water conditions every day. This is useful for detecting more quickly if anomalies in shrimp growth and water conditions can harm aquaculture.

Also Read: These are 7 Tips for Successful and Profitable Vannamei Shrimp Harvest

Vannamei Shrimp DOC 20 Cultivation

Vannamei shrimp cultivation always uses the age or day of culture (DOC) of shrimp as a benchmark in carrying out various actions related to pond management, one of which is how to feed it.

Feeding based on the age of the shrimp is helpful to prevent shortages or excess feed during cultivation which can inhibit the growth of vannamei shrimp.

Meanwhile, how to feed shrimp aged 20 days can be done by blind feeding method. While the type of feed given is in the form of granules with a frequency of 4 times a day and a feed dose of 25-15%.

This type of granule feed is suitable for shrimp from the age of 16 days to 45 days. Meanwhile, granules can be replaced with pellets until the vannamei shrimp are ready to harvest.

What is Aquaculture and Why is It Important?

What is aquaculture? Aquaculture is an action to breed, raise, and harvest aquatic organisms such as fish, shellfish, and crustaceans in a controlled environment, including ponds and tanks, by humans.

With increasing population, economic prosperity, and urbanization globally, the need for food is also growing. Meanwhile, we must rely on something other than capture fisheries that depend on nature. Therefore, aquaculture plays an essential role in meeting the demand for food.

Aquaculture has provided more than half of all fishery products we eat every day. In a way, aquaculture is the fastest-growing food-producing sector in the world and is playing an essential role in helping to meet food needs as the human population continues to grow.

Also Read: Vannamei Shrimp Salinity and How to Control Its Stability during Cultivation

What is Aquaculture?

What is aquaculture? Aquaculture is the production of aquatic organisms under controlled conditions throughout part or all of their lifecycle, with the majority being seafood such as fish, crustaceans, and shellfish. This activity is similar to agriculture, but the difference is what is bred in marine organisms.

To date, aquaculture is the fastest-growing food sector in the world. Moreover, with aquaculture, more sustainable seafood production activities can be carried out without damaging the environment.

Various types of aquaculture have been carried out until now. Cultivation purposes, operational techniques, and hydro-biological features distinguish these species. Meanwhile, shrimp and fish farming is arguably the most widely practised type of aquaculture worldwide.

Cultivating shrimp, fish, and other marine organisms is almost the same, starting with preparing ponds, seed selection, feeding and care, water quality management, and harvesting.

Why is Aquaculture Important?

Overfishing in the ocean continues to increase from year to year. This is because the increase in the human population makes the need for food also increase. Therefore, we need other alternatives to meet the needs of this seafood.

So, where lies the role of aquaculture? That being said, aquaculture is the right way to meet this seafood supply need. By cultivating aquatic commodities responsibly and sustainably, we can meet the needs of healthy protein for future generations while still being environmentally friendly.

Tiger shrimp (Penaeus monodon) is a sea shrimp native to Indonesia and has long been a mainstay of fishery export commodities. This shrimp has a distinctive striped pattern on its shell which makes it nicknamed The Black Striped Shrimp.

In their growth, tiger shrimp can reach a length of 35 cm and weigh up to about 260 grams. No wonder this shrimp has always been the belle of the world of aquaculture in Indonesia for years.

Meanwhile, vannamei shrimp (Litopanaeus vannamei) just entered Indonesia in 2001. This shrimp originally comes from the Pacific Ocean region and also has a high level of market demand.

In contrast to tiger shrimp, vannamei shrimp have smaller body sizes with transparent white body colors. This makes vannamei shrimp also known as white shrimp.

Choose Vannamei Shrimp or Tiger Shrimp for Cultivation?

Tiger shrimp vs vannamei shrimp cannot be directly compared. Both have their advantages for the shooters.

Before cultivating vannamei shrimp popular in Indonesia, tiger shrimp was the leading choice for farmers. However, the fame of the tiger prawns had declined due to an outbreak of white spot syndrome that attacked.

At that time, the mortality rate of tiger shrimp due to white spot disease reached almost 100% in just seven days. Because they don’t want to take risks, many farmers switch to vannamei shrimp.

Even so, market demand for tiger shrimp is still very high. So tiger shrimp cultivation can still be a profitable business.

Meanwhile, on the other hand, vannamei shrimp from the Pacific Ocean region seemed to steal the spotlight that tiger shrimp previously owned. Vannamei shrimp comes with various advantages when cultivated.

Some of the advantages of vannamei shrimp compared to other species include the following:

  • Being able to cultivate them with high stocking densities.
  • Being more resistant to disease and poor environmental quality.
  • Having a high survival rate.
  • A short cultivation time of around 90-100 days per cycle.

All those advantages above make vannamei shrimp superior when compared to tiger shrimp.
