How to Grow Plankton in Shrimp Ponds
There are several practical and easy ways to grow plankton in shrimp ponds. Plankton is an important component during vannamei shrimp cultivation because of its many benefits for shrimp survival.
Naturally, vannamei shrimp ponds contain a lot of plankton. These organisms play an essential role in pond ecology and affect water quality. However, under certain conditions, plankton can also bring problems in cultivation.
Plankton is very diverse, some of which can grow in almost any type of water. However, some are only able to grow in certain environmental conditions. Here’s how to grow plankton in shrimp ponds practically and efficiently.

How to Grow Plankton in Shrimp Ponds
1. Add Dolomitic Limestone
The first way to grow plankton in shrimp ponds is to add dolomite lime (CaCO3). Dolomite lime increases the alkalinity of pond water, which is used by nitrifying bacteria to convert ammonia (NH3) to nitrate (NO3), which plankton can use to grow.
2. Add Fermentation
Adding fermentation, such as molasses, can also be another way to grow plankton in shrimp ponds. The existence of this fermented material helps accelerate the growth of plankton in your vannamei shrimp pond.
3. Creating the Right Environmental Conditions for Plankton Growth
Plankton requires special conditions to grow in pond waters. Phytoplankton needs sunlight, nutrients, and carbon dioxide to grow. Meanwhile, zooplankton requires an adequate food source, oxygen, and appropriate water temperature.
To encourage the growth of phytoplankton and zooplankton in ponds, it is crucial to maintain a balance of ecosystems that provide the right amounts of these essential elements.
4. Controlling Nutrition Levels
Nutrient levels in shrimp ponds can have a significant impact on plankton growth. High levels of nutrients such as nitrogen and phosphorus can lead to high algae growth, while low levels of nutrients can result in poor phytoplankton growth rates.

Potential Adverse Effects of Plankton on Shrimp Ponds
Although plankton has many benefits, excess amounts of plankton can have negative impacts. For example, at night, in ponds with dense phytoplankton, the respiration of phytoplankton and other organisms can lead to low dissolved oxygen concentrations, suppressing or killing cultured species.
In addition, in ponds with low aeration or even no aeration at all, the presence of high plankton can reduce the depth of visibility under the pond water, which can cause dissolved oxygen concentrations at night to be too low.
Meanwhile, during the day, vannamei shrimp ponds with too many phytoplankton concentrations can cause the water pH to be too high. This is because phytoplankton carries out photosynthesis during the day and can drain water from existing free carbon dioxide.
