Stocking density optimization, aquaponics system design, feed conversion ratio analysis, and water quality modeling — grounded in USDA ARS and NOAA aquaculture research.
Official USDA price received and yield data by commodity, state, and year. Price auto-populates Storage Loss market price (SF23-S.003). Yield provides per-acre quantity reference for drying and storage calculators.
Source: USDA NASS QuickStats. Reference data used as fallback. Not endorsed by NASS.
Monthly USDA WASDE forecast — U.S. production, use, ending stocks, and projected season-average price. Use alongside NASS actuals to stress-test storage loss and drying calculations against forecast price scenarios.
Source: USDA FAS PSD Online (WASDE-aligned monthly forecast). Reference data used as fallback.
Side-by-side view of NASS historical actuals versus USDA WASDE forecast. Fetch both sources first, then select a commodity to compare. Use the price difference to run scenario analysis in the economics calculators.
Tip: Use the WASDE forecast price in economics calculators to model best-case / worst-case ROI scenarios alongside the NASS actual.
Calculate optimal fish stocking density for pond, tank, or raceway systems based on oxygen carrying capacity, water exchange rate, and target harvest weight. Based on USDA-ARS aquaculture research.
Balance fish biomass, plant growing area, and nitrification capacity in an aquaponic system. Calculates nutrient loading, plant uptake ratio, and system equilibrium parameters.
Calculate feed conversion ratio (FCR), specific growth rate, and protein efficiency ratio for aquaculture systems. Analyze feed cost per pound of fish produced using USDA-ARS aquaculture nutrition research.
Assess water quality risk in aquaculture systems by evaluating dissolved oxygen, ammonia, pH, and temperature interactions. Generates management alerts and corrective action recommendations.
Built on USDA-ARS Aquaculture Research Unit science — AgrStak SF23 science calculators translate federal aquaculture research into production-level decisions. From fish stocking density optimization and aquaponic system balance to feed conversion efficiency and water quality risk modeling, these 4 tools support commercial aquaculture producers, aquaponic operators, and extension specialists.
Models integrate USDA-ARS aquaculture nutrition research, water quality management science, and integrated recirculating aquaculture system (RAS) data. Part of AgrStak's 431-model platform — patent pending.
