## How is it calculated?

- Daily feed = Biomass × Feeding rate ÷ 100

- Period feed = Daily feed × Number of days

- Note: the calculation assumes constant biomass; as fish grow, update the feeding rate according to your table.

## FCRSOFT does this for you automatically

You don’t need to do the calculations and checks on this page by hand every day. FCRSOFT derives them all automatically from the records entered in the field.

- The daily feeding plan is generated from biomass.

- Feeding records entered in the field are deducted from stock automatically.

- Feedings that deviate from the plan are flagged in reports.
