Results

Biomass at harvest
40,000 kg
Fish at harvest
100,000 pcs
Juveniles to stock
117,647 pcs
Juveniles per m³
58.8 pcs

How is it calculated?

  • Harvest biomass = Volume × Target density
  • Fish at harvest = Harvest biomass × 1000 ÷ Harvest weight (g)
  • Juveniles to stock = Fish at harvest ÷ Survival rate

FCRSOFT

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.

  • Entering a sample weighing updates biomass and average weight.
  • Mortality and harvest exits are deducted from stock automatically.
  • Stocking density is tracked live for every cage.
