Fish Stocking Rate

Calculate optimal fish stocking density per acre based on pond size, species, and target harvest weight for sustainable aquaculture production.

Inputs

acres
lbs

Results

Stocking Rate

5,000 fish/acre

Total Fish to Stock

10,000 fish

Selected SpeciesCatfish
Fingerlings Needed (incl. mortality)11,765 fingerlings
Total Harvest Biomass15,000 lbs
Harvest Density7,500 lbs/acre
Growth Period18 months
Expected Survival Rate85%
How to Use This Calculator
  1. Enter Pond Size, Fish Species, and Target Harvest Weight.
  2. Review Stocking Rate (fish/acre) and Total Fish to Stock (fish).
  3. Use Selected Species and Fingerlings Needed (incl. mortality) (fingerlings) to inform your decision.
  4. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means

Pond Size
Total water surface area of the pond in acres. 1 acre = 43,560 sq ft.
Fish Species
Target species: 1 = Catfish, 2 = Tilapia, 3 = Trout, 4 = Bass.
Target Harvest Weight
Desired weight per fish at harvest time in pounds.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Pond Size = 2, Fish Species = 1, Target Harvest Weight = 1.5 = 3 input(s) provided
  2. Calculate Stocking Rate
    Stocking Rate
    5000 = 5000
  3. Calculate Total Fish to Stock
    Total Fish to Stock
    10000 = 10000
  4. Calculate Selected Species
    Selected Species = sp.name
    Catfish = Catfish
  5. Calculate Fingerlings Needed
    Fingerlings Needed
    11765 = 11765
