Aquaponics Stocking
Stocking density, fish biomass and daily feed amount.
About Aquaponics Stocking
Fish count comes from tank volume and density, total weight is biomass, and a percent of that is fed daily. Fish both produce plant nutrients and consume dissolved oxygen, so density and feeding drive the whole balance.
Formula
Aquaponics Stocking
Fish = tank x density; biomass = fish x weight; feed = biomass x rate%
- stocking density
- Fish per gallon, low for grow-out systems
Worked example
With the default values below, Aquaponics Stocking returns Fish to Stock of 50. Change any input above and every figure here is recalculated in your browser.

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 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
How is Aquaponics Stocking calculated?
Fish = tank x density; biomass = fish x weight; feed = biomass x rate% Fish count comes from tank volume and density, total weight is biomass, and a percent of that is fed daily.
Why does Aquaponics Stocking matter?
Fish both produce plant nutrients and consume dissolved oxygen, so density and feeding drive the whole balance.
What values do I need to enter?
This calculator takes 4 inputs: Tank volume, Stocking density, Average fish, Feed rate. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
