Calculated Survival Rate

100.0%

Estimated Pond Biomass

How the Formula Works

Est. Surviving = Avg Pcs per Cast Net × 4,047 | Survival % = (Est. Surviving ÷ Total Stocked) × 100

Why This Calculation Matters:

Cast net sampling provides an empirical field estimate of population before negotiating harvest buyers and ice requirements.

Pro Farming Tips:

  • Take at least 8 to 10 cast net samples across different pond areas (corners, center, near aerators) for an accurate average.
