What does "on-track" mean?

On-track means actual growth is 90–110% of the required pace. Ahead is >110%, behind is 70–90%, and critical is <70%.

How often should I check growth performance?

Monthly sampling is standard. Bi-weekly checks are recommended during critical growth phases or when problems are suspected.

What should I do if growth is behind?

Check water quality (temperature, DO, ammonia), feeding rates, feed quality, stocking density, and health status. Adjust the timeline if necessary.

Representative sampling

Sample at least 30 fish from different areas of the tank/pond to get an accurate average weight.

Growth catch-up is possible

Fish that fall behind due to a temporary stressor can sometimes achieve compensatory growth when conditions improve.

Method

Compares actual ADG to required ADG as a percentage. Status thresholds: ahead (≥110%), on-track (90–110%), behind (70–90%), critical (<70%).

Growth Performance Monitoring

Tracking actual growth against planned targets is essential for production management. Early detection of growth shortfalls allows timely intervention (adjusting feed, water quality, or stocking) before harvest delays become inevitable. This tool compares actual vs required average daily gain (ADG) to give a simple traffic-light status.
