Cohort Biomass Explorer

A live implementation of the BiologicalModel — staggered batches of smolts grow on a sigmoid curve, thin out under linear mortality, consume feed against FCR, and land as single-month HOG harvest. Adjust any parameter to see the system respond in real-time.

Standing Biomass in the Water

Total live weight across all active cohorts. Plateau height indicates steady-state stock the site must hold.

Cohort Overlap — The Water Column

Each band represents one batch's biomass. They stagger and stack into the total above.

Single Cohort Lifecycle

Sigmoid weight gain (k=7) versus linear mortality decline for a single batch.
