Design a hatchery to supply local fish farmers with 200,000 African catfish and 300,000 tilapia fingerlings per year (5 g).
Separate recirculating aquaculture systems (RAS) for catfish, tilapia and broodstock replacement, each with: cyclone pre-filter → drum filter → moving-bed biofilter → UV disinfection → sump. Bio-blocks above the tanks strip CO₂ and add oxygen.
Water is heated by solar heaters made of black HDPE pipe on the roof, with no fuel costs. Catfish eggs are incubated in Weiss jars. A flow-through quarantine tank and a settling pond treat the discharge before it reaches the river.
Send the species, target capacity and site location. Dmitry Yakovlev, PhD, will review your inputs and suggest the next step: feasibility study, CAPEX/OPEX estimate or engineering design.
