Ammonia in Vannamei Shrimp Ponds

Ammonia is a chemical compound formed as a byproduct of shrimp metabolism and undigested feed. High concentrations of ammonia can disrupt shrimp’s health, poison them, and even lead to mortality. Therefore, controlling ammonia is key to achieving success in Vannamei shrimp aquaculture.

Ammonia is a chemical compound generated from shrimp metabolism, the accumulation of unconsumed feed, decomposition of dead organisms, and feces. In shrimp ponds, there are two types of ammonia: free ammonia (NH3) and ionised ammonium (NH4+), which are accumulated as Total Ammonia Nitrogen (TAN).

Essentially, ammonia is also required in the shrimp pond ecosystem for the nitrification process by plankton. However, ammonia levels in the pond should not exceed 0.1 ppm to ensure healthy shrimp growth.

Causes of High Ammonia Levels in Ponds

1. Shrimp Metabolism

The metabolism of Vannamei shrimp produces ammonia as a byproduct. The more shrimp cultivated in the pond, the more ammonia is produced through their metabolic processes.

2. Overfeeding

Overfeeding can result in an excess of leftover feed that rots and accumulates at the pond’s bottom, becoming a source of ammonia.

3. Suboptimal Water Temperature

Elevated water temperatures can increase shrimp metabolism, leading to higher ammonia production. Conversely, when the water temperature is too low, the growth of ammonia-reducing bacteria can be inhibited, impeding ammonia breakdown.

4. Poor Waste Management

Organic waste from Vannamei shrimp cultivation, such as unconsumed feed, feces, and deceased organisms, accumulates at the pond’s bottom. Inefficient waste management systems can lead to waste accumulation, which contributes to elevated ammonia levels.

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.

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.

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%.

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

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.

Addressing Harmful Algal Blooms in Shrimp Ponds

In the cultivation of vannamei shrimp, various types of algae or plankton exist within the shrimp ponds. The presence of diverse plankton indicates that the pond environment is stable and healthy. However, harmful algal blooms, or a sudden increase in the number of plankton, can be detrimental to the shrimp’s survival.

Harmful algal blooms or plankton explosions occur when there is a rapid rise in the population of algae in the pond, causing a change in the colour of the pond water. These blooms can be harmful to shrimp as certain types of algae can release toxins.

What is Algae?

Algae, also known as phytoplankton, are microscopic organisms that move freely and float in the pond water. The presence of algae directly affects the colour of the pond water.

In vannamei shrimp farming, algae serve as both a natural shrimp feed and a source of oxygen beneficial for shrimp respiration. However, the presence of algae must be consistently controlled to avoid harmful algal blooms that can threaten shrimp survival.

Also Read: Treat or Toxin: Plankton – Friend or Foe?

Importance of Algae in Shrimp Ponds

1. Oxygen Source

Algae play a crucial role as suppliers of more than 30% of the total oxygen needed by vannamei shrimp in the pond. This oxygen is produced through photosynthesis during daylight with the assistance of sunlight.

However, in intensive to super-intensive vannamei shrimp farming, additional oxygen supply through the use of aerators is typically required.

2. Natural Shrimp Feed

The presence of algae in the vannamei shrimp farming industry is essential and valuable. These microscopic organisms serve as a food source for shrimp larvae. As a natural feed, the presence of algae in the pond needs to be controlled daily.

3. Pollution Indicator

Algae can also indicate contamination in your shrimp pond, particularly when their growth becomes uncontrolled. This is caused by increased mineral content in the water due to agricultural chemicals and fertilizers rich in nitrogen and phosphorus.

What is Algal Blooming?

Algal blooming refers to a rapid increase in the accumulation of algae populations within shrimp ponds. This occurrence is usually identified by changes in the pigment color of the water.

Algal blooming results from an excessive accumulation of nitrogen or phosphorus fertilizers in the pond environment, leading to excessive algae growth. Algal blooms can be detrimental to vannamei shrimp farming, such as preventing sunlight from entering the ponds and causing a decrease in oxygen levels in the water.

Causes of Algal Blooms

1. Nutrient Excess

Excessive nutrients can lead to uncontrolled growth in phytoplankton populations in shrimp ponds. The increased population of phytoplankton, also known as algal blooms, is indicated by a change in water colour to a dense green. During algal blooms, the pond loses oxygen intake, and the water’s pH becomes unstable and fluctuates.

2. Presence of Organic Waste

Vannamei shrimp ponds generate a considerable amount of organic waste, originating from unconsumed feed, dead shrimp, and shrimp feces. If this waste is not properly managed, it can lead to uncontrolled algae growth.

Impacts of Algal Blooms in Shrimp Ponds

Green-coloured pond water is quite common and indicates a rich plankton environment. However, when plankton populations become excessive, it can have negative effects on shrimp survival.

When plankton populations explode uncontrollably, the pond water becomes densely green. This density prevents sunlight from penetrating the pond, depriving the shrimp of sunlight exposure.

This high density also inhibits proper oxygen circulation. Consequently, shrimp may experience oxygen deficiency, especially if there is no aerator supporting oxygen circulation in the pond.

Ways to Address Algal Blooms in Shrimp Ponds

1. Reducing Pond Nutrient Levels

Reducing nutrients means reducing the amount of feed provided to the shrimp in the pond. This is because excessive, unconsumed feed will settle at the bottom of the pond. This sedimentation can trigger algal blooms.

Therefore, managing proper feed distribution is crucial. This includes reducing the feed provided when the shrimp are in a less voracious feeding phase.

2. Ensuring Proper Aeration

Ponds lacking a proper aeration system can be a triggering factor for the excessive growth of phytoplankton. Thus, ensuring that the existing pond aerators operate continuously is essential for reducing the phytoplankton population.

Poor aeration can lead to the accumulation of waste at the pond bottom. Aeration also helps increase the level of dissolved oxygen in the water.

Treat or Toxin: Plankton – Friend or Foe?

What lies beneath? With limited tools to see what is in our water, the microbiome is hard to measure while its management is vital to consistent success.

This poses constant challenges which should spook us into action, a healthy microbiome resists pathogenic factors and promotes growth and survival.

Plankton are free-living microscopic organisms that drift in water columns. They are classified into two groups: phytoplankton and zooplankton. Phytoplankton are a group of plankton that can produce their own food from inorganic compounds such as ammonia and carbon dioxide. Zooplankton are plankton groups that get their nutrition from organic compounds such as organic carbon and leftover feed. In shrimp farming, we usually report phytoplankton daily with four different classifications.

Then, is plankton a trick or treat for your shrimp farm? Read the full article written by Gabrian Suryaputra (Researcher at RnD Department of DELOS) on THE CRUST Magazine Issue #13
