The demand for high production often pushes shrimp farmers to focus solely on achieving production targets, sometimes overlooking one crucial aspect, carrying capacity. Carrying capacity refers to the ecological suitability level that determines the maximum biomass or residual water load that a pond ecosystem can sustain. Ideally, it’s determined by the balance between the rate of waste generation from farming activities and the ecosystem’s ability to recycle or discharge that waste.
Carrying capacity of a shrimp pond is influenced by several factors, including pond size and depth, the aeration system (number and capacity of paddlewheels), and the availability of Dissolved Oxygen (DO). In addition, the type of feed and its management, wastewater handling, and overall water quality conditions play vital roles in maintaining ecosystem balance and supporting shrimp growth.

Why Carrying Capacity Matters in Shrimp Farming
Farmers should pay attention to carrying capacity to keep their farming activities optimal, understanding this helps to:
- Ensure the number of shrimp does not exceed the pond’s environmental limits, keeping water quality stable.
- Prevent stress and disease, as shrimp living in optimal conditions have stronger immunity.
- Maximize production by maintaining appropriate stocking density for optimal growth and higher yields.
- Keep ponds productive across multiple farming cycles for long-term sustainability.
How to Calculate Carrying Capacity
Carrying capacity can be calculated using simple to more advanced scientific approaches. Below are practical methods farmers can apply:
