How to Use the Tilapia Stocking Density Calculator
Free. No sign-up. Works on your phone.
What it gives you
- Fingerlings to stock, from pond area and density per square meter.
- Fish expected at harvest, from your survival rate.
- Expected harvest in kilos and in kilos per square meter.
- A rating: normal, high or crowded, with or without an aerator.
Stock too few fingerlings and the pond is wasted; stock too many and the fish grow slowly and the water turns bad. This free calculator gives the number to stock for your pond size and tells you if the harvest fits what the pond can carry.
How to use the Stocking Density, step by step
Open the tool
Go to arandcagriventures.com, tap Tilapia Tools, then choose Stocking Density.
Enter the pond area
Type the water surface area in square meters.
Set the stocking density
Fish per square meter. Three per m² is a common starting point for ponds without aeration.
Set the expected survival
The percentage of fish you expect to reach harvest.
Enter the harvest weight
The average weight per fish you plan to sell at, in grams.
Choose aerator or no aerator, then tap Calculate
The result shows the fingerlings, the harvest and the rating.
The example in the video
| Pond area | 1,000 m² |
|---|---|
| Stocking density | 3 fish per m² |
| Expected survival | 70% |
| Harvest weight | 300 g |
| Aerator | No aerator |
| Fingerlings to stock | 3,000 pcs |
|---|---|
| Fish at harvest | 2,100 |
| Expected harvest | 630 kg |
| Load at harvest | 0.63 kg per m² (Normal) |
How to read the result
At 3 fish per m², a 1,000 m² pond takes 3,000 fingerlings. With 70% survival and 300 g fish, that is 2,100 fish and 630 kg at harvest, or 0.63 kg per m². A pond without an aerator carries about 1 kg per m², so this is rated Normal. Above 1 kg per m² the tool warns that the pond is getting crowded.
Questions growers ask
How many tilapia fingerlings per square meter?
Around 3 per square meter is a common starting density for ponds without aeration. The right number depends on your water supply, aeration and harvest size, which is what the calculator checks.
How many fingerlings for a 1,000 square meter pond?
At 3 per m², stock 3,000 fingerlings. With 70% survival and 300 g harvest weight, expect about 630 kg.
