Fish Yield Calculator

Calculate the expected yield of fish based on initial stock, growth rate, and harvest period

Input Parameters

Calculation Results

Calculation Formula

Final Yield = Initial Stock × (1 + Growth Rate/100)^Harvest Period × Harvest Efficiency/100

Where:
Initial Stock: The starting weight of fish stock in kilograms
Growth Rate: Monthly growth percentage of the fish stock
Harvest Period: Number of months the fish are grown before harvesting
Harvest Efficiency: Percentage of fish that can be harvested successfully

Results

Final Yield (kg):

0.00

Total Growth:

0.00 kg

Harvested Amount (kg):

0.00 kg

Fish Yield Calculator Calculator Usage Guide

Learn how to use the Fish Yield Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the Initial Stock of fish (in kg) you start with.
  2. Input the Growth Rate as a percentage per month (e.g., 5% for 5% growth per month).
  3. Specify the Harvest Period in months.
  4. Enter the Harvest Efficiency as a percentage (e.g., 90% if you expect to harvest 90% of the final yield).
  5. Click the Calculate button to see the expected yield.
  6. Use the Reset button to clear all inputs and start over.

Principle Explanation

This calculator uses the compound growth formula to estimate fish yield. The growth is calculated month by month, compounding the growth rate over the specified harvest period. The harvest efficiency accounts for any losses during harvesting.

Example

Suppose you start with 100 kg of fish (Initial Stock), expect them to grow at 4% per month (Growth Rate), and plan to harvest them after 6 months (Harvest Period). If your harvest efficiency is 85% (Harvest Efficiency):

The final yield would be calculated as:

100 kg × (1 + 4/100)^6 × 85/100 = 100 kg × 1.2653 × 0.85 = 107.80 kg

Applications

This calculator can help aquaculture farmers:

  • Plan production targets
  • Optimize harvest timing
  • Estimate potential income
  • Make informed decisions about resource allocation
