Calculators
Pond stocking
density norms by species, survival, harvest forecast kg/ha
Stocking density
ha × mode → fish count
Fish feeding
daily ration % of biomass by water temperature, FCR feed cost
Daily feed rate
% of biomass by water temperature
Pond volume & aeration
pond m³, aerator kW by intensity, exchange flow
Polyculture
species mix and stocking split
Cycle profitability
costs vs harvest revenue
Water parameters
oxygen, pH, temp, ammonia by species
Fingerlings
quality assessment: size, uniformity, activity, origin, transport
Growth forecast
stocking → market weight over weeks
Fish diseases
symptoms and prevention
Wintering
wintering norms: depth, oxygen, ice cover, overgrowth, preparation
Documents
permits, water use, veterinary, business form, reporting — full list
Paid fishing pond
fees vs catch and restocking
Fish sales
channels: live fish, processing, paid fishing, wholesale — margins and docs
RAS
calculation: volume, density, biofiltration — when it pays off
Water rights
Water rights for fish farming: lease, special water use, permits, common mistakes
Feed base
zooplankton, fertilization, melioration — cutting feed costs
Dam & levee
Trapezoid cross-section → m³ of soil, +12% compaction, works estimate
Ice & winter risks
Winter kill: oxygen monitoring, ice holes, aeration, pond winter preparation
Aquaponics
fish + plants: balance, crops, economics, starter setup
