1. What is a Tilapia Stocking Density Calculator?

Definition: This calculator determines the stocking density of tilapia fish in aquaculture systems based on the number of fish and water volume.

Purpose: It helps aquaculturists maintain optimal fish density for healthy growth and efficient resource use.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( D \) — Stocking density (fish/m³)
• \( N \) — Number of fish
• \( V \) — Water volume (cubic meters)

Explanation: The number of fish is divided by the water volume to determine how many fish can be sustainably raised per cubic meter.

3. Importance of Stocking Density Calculation

Details: Proper stocking density ensures fish health, optimal growth rates, and prevents overcrowding that can lead to disease and poor water quality.

4. Using the Calculator

Tips: Enter the number of tilapia and the water volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the recommended stocking density for tilapia?
A: Typically 10-20 fish/m³ for extensive systems, 20-50 fish/m³ for semi-intensive, and 50-100 fish/m³ for intensive systems with aeration.

Q2: How do I measure my water volume?
A: For rectangular tanks: length × width × depth. For circular tanks: π × radius² × depth.

Q3: When should I adjust stocking density?
A: Reduce density if you notice poor growth, disease, or water quality issues. Increase only with proper aeration and filtration.

Q4: Does this include fry or only adult fish?
A: Calculations should be based on expected final size. You may start with higher numbers and thin out as fish grow.

Q5: How does stocking density affect feeding?
A: Higher densities require more precise feeding management to maintain water quality and prevent overfeeding.
