This Is the Best Water Color for Vannamei Shrimp Pond

Pond water is an indicator that must always be considered when cultivating. The best color for vannamei shrimp pond is brownish green and dark green. This colors can describe the living conditions of the shrimp in it. However, this color only becomes a benchmark and farmer needs to check it with other indicators regularly.

Each pond can have a different color of the water. This color can indicate the types of organisms that are in it. Through the visible colors of pond water, farmers can identify anomalies and predict if problems arise.

What color of water is the best for vannamei shrimp pond? Let’s learn about it through this article!

The Meaning of Pond Water Colors

The color of pond water is not always bright blue like seawater. Many color variants indicate certain conditions in ponds. Here are the meanings of pond watercolors that you need to know.

1. Greenish Yellow

The color of pond water greenish yellow is indicating that the amount of phytoplankton in the pond is still unstable, so TSP or urea is needed. Farmers must carry out routine checks to observe changes when applying this fertilizer. If it is still changing and not stable, farmers can add dolomite lime.

2. Brownish Green

When pond water is green-brown, it means that the water contains sufficient phytoplankton. This color is the best color for vannamei shrimp pond. However, to maintain its stability, it is necessary to apply fertilizer every week.

3. Blue Green

The bluish-green color in vannamei shrimp ponds indicates abundant blue-green algae phytoplankton. This shows that there are porous shrimp, and it is necessary to replace the water, add dolomite lime, and apply TSP fertilizer.

4. Dark Green But Not Concentrated

The color of pond water is dark green, indicating that the amount of phytoplankton in the water is relatively stable. This color is the best water color for vannamei shrimp pond. Meanwhile, to optimize it, farmers can give a little TSP fertilizer while continuing to observe if there is any changes.

5. Deep Dark Green

When pond water is thick dark green, and feels slimy, this indicates that there is toxic phytoplankton which can cause many shrimp to get sick. Of course, this color is not the best color for vannamei shrimp pond and farmer must avoid it.

But there is no need to worry about overcoming this can be done by replacing water and giving dolomite lime.

6. Dark Brown

The dark brown color of pond water indicates a lack of phytoplankton growing in it. To overcome this, urea and TSP fertilizers can be used, and further land reclamation is needed.

7. Reddish Brown

When the color of the pond water is reddish brown, this indicates a high content of toxic phytoplankton and sulfuric acid. To deal with this, you need to neutralize it by changing the water, giving lime, giving urea fertilizer, and rinsing the pond repeatedly.

8. Black

The black pond water color indicates that the phytoplankton is not growing properly. In addition, this color can also be an indication of the amount of decaying organic matter at the bottom of the pond. Of course, this color is not the best water color for vannamei shrimp pond.

The only way to overcome this condition is to remove the sludge that has settled at the bottom of the pond until it runs out.

Indicators of Pond Water Quality

Knowing the quality of pond water is an important thing that must be done every day. This is to make it easier if there are changes or anomalies, farmers can take steps as quickly as possible.

Not only observing the color of pond water which is suitable for vannamei shrimp but there are also other indicators that must be monitored regularly every day. The following are the indicators:

1. Pond Water Color

As previously explained, the color of pond water indicates the quality of the water in it. The best color for vannamei shrimp pond is dark green without slime and light brown.

2. Pond Water Brightness

Good pond water brightness ranges from 25-60 cm. Meanwhile, the brightness number is below it. In that case, it is difficult for sunlight to penetrate the water, resulting in low water temperatures and the photosynthesis process not running optimally.

3. Pond Water pH

pH is the level of acidity of water that is measured physically and greatly affects the organisms that live in it. The ideal pond water pH ranges from 7.5-8.5. Changes in pH in vannamei shrimp ponds can cause shrimp to become stressed. Therefore, it is vital to keep the pH ideal.

4. Dissolved Oxygen

Dissolved oxygen, also known as DO, supports shrimp in the respiration process. This indicator also dramatically affects the growth of shrimp. Usually, to keep the DO stable, aerators are used according to the needs of each pond.

5. Water Temperature

The ideal pond water temperature ranges from 28-31 degrees Celsius. Farmers must maintain this perfect temperature to remain stable every day. This is because temperatures that decrease or increase drastically can cause the death of shrimp in large enough numbers.

6. Pond Water Alkalinity

A good level of alkalinity concentration for vannamei shrimp is 130-180 ppm. This alkalinity is the ability of water to neutralize additional acids without lowering the pH level of the water. Alkalinity indicators need to be monitored regularly because they directly affect the growth of shrimp and supporting microorganisms in pond ponds.

7. Water Salinity

The ideal pond water salinity ranges from 15-25 ppt. This salinity condition must be maintained to remain stable. This is because less salinity can result in less optimal shrimp growth. In addition, too fast fluctuations in salinity can also cause stress in shrimp and can trigger death.

5 Characteristics of Intensive Vannamei Shrimp Pond You Should Know

An intensive vannamei shrimp pond is a type of pond that was developed as a means to increase the productivity of vannamei shrimp aquaculture. However, on the other hand, intensive ponds also produce more waste due to their high stocking density.

The waste from this intensive pond comes from the feed given to vannamei shrimp, usually in the form of carbon, nitrogen, and phosphorus compounds. These three compounds can decompose naturally on their own but in a longer time than one cultivation cycle. Therefore, waste will accumulate if the leftover materials from a prior process are not correctly disposed of.

In addition to residual waste, the calculation and layout of intensive vannamei shrimp ponds are more complex when compared to other types of ponds.

Characteristics of Intensive Vannamei Shrimp Pond

Vannamei shrimp-intensive ponds have unique characteristics that are different from other types of ponds. This is influenced by the stocking density of this type of pond. The characteristics of vannamei shrimp ponds are as follows:

1. Not Affected by Tidal Cycles

Water sources in intensive ponds do not depend on the ebb and flow of seawater. So, even when the sea water recedes, the water in the pond will not be affected.

2. Regularly Shaped Pond Plot

Intensive ponds have a regular pond shape. Usually, it is a square with an area of 0.2-0.5 ha per plot.

3. Using Aeration System

Another characteristic of intensive ponds is the existence of an aeration system in ponds that is useful for increasing dissolved oxygen in pond waters. This aeration system is usually supported by waterwheels, blowers, source pumps, and other equipment.

4. High Stocking Density

In an intensive cultivation system, it is necessary to adjust the stocking density so that production results can be maximized with minimal costs.

Stocking density determines the level of technology required in the cultivation system.

5. Rely on Artificial Feed

Considering the high stocking density of shrimp fry in intensive pond types, the need for feed is also high. Therefore, since the fry is stocked, the need for feed is immediately met with artificial feed.

Purpose of Adjusting Vannamei Shrimp Stocking Density

The stocking density of vannamei shrimp fry must be adjusted to the capacity of the existing pond. This is because the stocking density affects the pond’s productivity and the costs incurred for cultivation.

1. Maintain Good Water Quality

Water quality in vannamei shrimp culture is influenced by feed residues and faeces. The greater the density of vannamei shrimp during cultivation, the more feed residues and manure are produced.

If there is too much manure and leftover feed is in the water, water quality conditions can be disturbed and even toxic.

2. Maintain the Growth of Vannamei Shrimp

The stocking density of vannamei shrimp that is not adjusted to the capacity of the pond can cause the cultured shrimp not to grow well. This is because shrimp will fight for space and nutrients from food which can cause shrimp growth to be slow if the stocking density is too high. Meanwhile, if the stocking density is too low, the space utilisation will be less than optimal.

3. Avoid Disease Attacks

Adjusting the stocking density of white shrimp can also prevent shrimp from disease during cultivation. If the stocking density is too high, the risk of death of vannamei shrimp during disease is also quite high, and vice versa.

The Importance of Alkalinity in Shrimp Ponds, Check Your Alkalinity Now!

Alkalinity in shrimp ponds is the capacity of pond water to neutralize acid, which is measured based on its constituent components in the form of bicarbonate ions (HCO3-), carbonate (CO32-), and hydroxide (OH-). Alkalinity is an important parameter of water quality and influences the success of cultivation.

Alkalinity is also a buffer or water pH buffer. Stable water pH is crucial for shrimp growth because any fluctuation outside the optimum limit can cause stress, decreased growth rate, susceptibility to disease, and even death.

Water in an aquaculture system can come from direct watershed runoff, rivers, lakes, estuaries, seas, or wells with varying alkalinity values. If the alkalinity is low, liming is usually done to increase it.

What Is Alkalinity in Shrimp Pond?

Alkalinity is the ability of water to buffer pH by neutralizing hydrogen cations using water anion components which include bicarbonate ions (HCO3-), carbonate (CO32-), and hydroxide (OH-). Therefore, alkalinity is an important water quality parameter in shrimp ponds.

Maintaining optimal alkalinity in shrimp ponds is critical to stabilizing pH levels, which can affect shrimp health and growth. Optimal alkalinity in shrimp ponds ranges from 130-180 ppm.

Alkalinity below the optimum range in shrimp ponds can cause pH fluctuations. This can cause stress to the shrimp and increase the risk of disease outbreaks. Agricultural lime is usually added gradually to overcome this until it reaches the optimum alkalinity range.

Factors Affecting Changes in Alkalinity

The alkalinity may remain constant, increase, or decrease during the shrimp culture period. Occasionally, the reduction may be so drastic as to require additional liming to keep the alkalinity within the optimal range.

1. Adding Water to the Pond

Adding water to pond ponds can often cause the alkalinity to change. For example, the alkalinity will decrease when a pond gets additional healthy water. To overcome this, farmers need to add limestone, which will dissolve and increase the alkalinity of the water.

2. High Rainfall

In addition, high rainfall can also affect changes in pond alkalinity. Significantly when water evaporation exceeds precipitation, which causes alkalinity to increase. On the other hand, if the precipitation is higher, the alkalinity will decrease because rainwater usually does not contain measurable alkalinity.

3. Denitrification Process

Denitrification, or the process of reducing nitrate to nitrogen gas by bacteria that occurs in ponds, can also increase the alkalinity of the water. This is because denitrification releases one hydroxide ion for every nitrate ion converted into nitrogen gas. While the nitrification process releases two nitrogen ions for every ammonium ion converted to nitrate.

Tips to Increase Alkalinity Value in Shrimp Ponds

1. Increase Alkalinity in Shrimp Ponds with Addition of Dolomite (Calcium Magnesium Carbonate)

Dolomite is widely used to increase alkalinity values. This is because dolomite is also rich in calcium, magnesium and carbonate. With the addition of dolomite lime, the alkalinity of the water can be appropriately maintained.

2. Soda Ash (Sodium Carbonate)

Soda sodium carbonate can also be used to increase the alkalinity of water. However, its use is better done by adding it little by little in one day to hold pH variations properly.

3. Increase Alkalinity in Shrimp Ponds with Baking Soda (Sodium Bicarbonate)

Lastly, baking soda can also be used to increase the alkalinity value of water. Applying sodium bicarbonate is also the same: mixing it gradually into the pond water.
