How to Use This Calculator
  1. Enter Water Body Area (acres) and Average Depth (feet) to establish carrying capacity.
  2. Input Summer Water Temperature (°C) — warmer water limits dissolved oxygen and reduces stocking density for cold-water species.
  3. Select Species (trout, bass, bluegill, catfish, etc.) to apply species-specific density requirements.
  4. Set Stocking Goal (trophy fishery, put-and-take, balanced ecosystem) and Natural Reproduction level.
  5. Review Total Fish to Stock and Stocking Rate (fish/acre) to plan your hatchery order.
  6. Adjust inputs seasonally and after each stocking event to track cumulative population toward carrying capacity.
