- 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.
