Fish Pond Stocking Calculator

Work out fish pond stocking instantly with clear inputs, formula shown and shareable results.

About Fish Pond Stocking Calculator

Multiplies pond area by the stocking rate, applies expected survival and converts the surviving fish into a harvest weight.

Formula

Pond stocking

Fingerlings = area x stocking rate; harvest number = fingerlings x survival; yield = harvest number x target weight / 1000

Worked example

With the default values below, Fish Pond Stocking Calculator returns Fingerlings to stock of 4,000. Change any input above and every figure here is recalculated in your browser.

Inputs used

Pond areaaccepts 1–1,000,000 m2: 1,000 m2
Stocking rateaccepts 0.1–100 fish/m2: 4 fish/m2
Expected survivalaccepts 20–100: 85
Target harvest weightaccepts 10–10,000 g: 500 g

Results

Fingerlings to stock: 4,000
Fish expected at harvest: 3,400
Expected yield: 1,700.00 kg
Yield per hectare: 17,000.0 kg/ha

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What limits the stocking rate?

Dissolved oxygen and feed supply. Rates above 3 to 4 fish per square metre usually require aeration.

Should mortality be front-loaded?

Yes. Most losses occur in the first weeks after stocking, so early survival checks matter most.
