Indoor Aquaculture + RAS MEP for India — FAO + BAP + ASC + CIBA + CPCB Aquaculture

A 500 t/yr indoor RAS shrimp + tilapia farm demands ₹153 Cr MEP capex with mechanical + biological filtration + UV + foam-fractionator + LOX + 2N recirculation pumps + 24-hr backup. FAO + BAP + ASC + CIBA + CPCB govern. Indoor RAS uses 50 L/kg water (vs 8000 L/kg open-pond) with 40 kg/sqm/yr yield. Three failures: biofilter under-sized for 2-3x peak NH3 spike at feeding causing toxicity die-off, backup power without redundant pumps allowing 30-min ride-through kill, CPCB effluent compliance ignored discharging raw causing CAA closure.

Indoor aquaculture + RAS Recirculating Aquaculture System framework

India aquaculture (Avanti Feeds, Coastal Corp, Devi Sea Foods, IFB Agro) shifting from open-pond shrimp + fish to indoor Recirculating Aquaculture Systems (RAS) for biosecurity + climate-resilience + protein-efficiency. Standards stack — FAO Aquaculture Code of Conduct + BAP Best Aquaculture Practices + ASC Aquaculture Stewardship Council + WHO Sanitation in Aquaculture + Indian Coastal Aquaculture Authority + CIBA Central Institute of Brackish-Water Aquaculture + CPCB Aquaculture Effluent.

Indoor RAS shrimp + tilapia farm MEP — 500 t/yr production

Three Indian indoor aquaculture MEP failures

1. Biofilter under-sized for nitrification peak — shrimp + tilapia produce NH3 spikes during feeding. Standard nameplate biofilter cannot handle 2-3x peak — NH3 toxicity event kills stock. Specify 3x peak ammonia + 2-week start-up cycling.
2. Backup power without redundant recirculation pumps — RAS depends on continuous flow; 30-min stoppage = oxygen depletion + die-off. Specify 2N pumps + 24-hr UPS + DG auto-start + battery for 90-min ride-through.
3. Effluent CPCB compliance ignored — RAS produces concentrated effluent (NO3 + suspended solids). CPCB Aquaculture norms require dedicated treatment before discharge. Many Indian indoor farms discharge raw — face Coastal Aquaculture Authority closure.
