Aquaculture & biofloc
Plan tank volume, stocking, feed, aeration and water-quality arithmetic with visible farm assumptions.

- Energy charge
Aquaculture salt and alkalinity dosing calculator
Estimate NaCl for a salinity increase and sodium bicarbonate equivalent for an alkalinity increase.
- Salt mass balance
- Bicarbonate equivalent
- Editable initial and target values
TAN to un-ionized ammonia calculator
Estimate the unionized NH₃ fraction and concentration from TAN, pH and water temperature.
- Temperature-adjusted fraction
- NH₃ mg/L screen
- Explicit equation scope
Fish survival rate and harvest biomass calculator
Estimate survivor count and harvest biomass from initial stock, expected survival and harvest weight.
- Survivor count
- kg and tonnes
- Editable survival scenario
Measure the system before changing it
Start with water volume, standing biomass, feed records, meter readings and tested water values. Each calculator makes one part of the farm arithmetic visible; no single output describes the whole production system.
Treat water and animal-health inputs as operational data
Stocking, carbon additions, aeration and chemistry changes can affect fish welfare quickly. Use calibrated tests, farm-specific protocols, species guidance and qualified local advice before acting on a calculation.
