Aquaculture Yield and Feed Projection Report

You calculate FCR by dividing the total weight of feed distributed by the total wet weight gain of your fish over a specific period. For most commercial species like tilapia or trout, a highly efficient target FCR ranges between 1.1 and 1.5. Keeping this ratio low requires precise feed sizing, strict temperature tracking, and avoiding wasted feed.

A safe stocking density for intensive RAS typically ranges from 40 to 80 kilograms of fish per cubic meter of water, depending entirely on your filtration and oxygenation capabilities. Exceeding these limits risks sudden biological filter collapse and lethal ammonia spikes. Always design your system with a 15% safety margin below maximum carrying capacity.

Fish are ectothermic, meaning their metabolism and feeding activity rise and fall directly with the surrounding water temperature. Your feed chart must scale down daily rations during colder months or extreme heat waves to prevent uneaten feed from rotting on the pond floor. Conversely, optimal temperature ranges require aggressive feeding to maximize growth rates.

Standard projections should assume a baseline cumulative mortality rate of 5% to 15% from fingerling to harvest, depending on species resilience and water source security. Spread this loss incrementally across the weekly projections rather than deducting it all at the end of the cycle. This ensures your active biomass calculations and feed distribution volumes remain accurate throughout the season.
