High-Density Biofloc GIFT Tilapia
Commercial aquaculture blueprint covering target water quality tolerances, extruded floating pellet nutrition, biosecure disease prophylaxis, and PMMSY 40%–60% capital grant eligibility.
Medium Biofloc Unit (7 Coated PVC Tanks of 4m Diameter)
Tailored to maintain high biomass carrying capacity, dissolved oxygen stability, and non-stress environmental conditions.
- Zero-land intensive aquaculture: Requires only 300 to 500 square meters of shed space for a 7-tank unit
- Microbial Biofloc technology recycles toxic fish ammonia into protein-rich microbial biomass (flocs) using carbon sources (jaggery/molasses)
- Exceptional FCR of 1.2 to 1.3: Fish continuously graze on suspended bioflocs, reducing commercial pellet feed bills by 25%
- Eligible for ₹7.5 Lakhs PMMSY standard unit cost subsidy (40% to 60% DBT release)
Stocking Density & Survival Targets
Target Water Chemistry Parameters
Daily monitoring thresholds required to avoid ammonia toxicity, gill asphyxiation, and stress-induced mortalities.
Precision Extruded Pellet Feeding Schedule
Optimized crude protein and feeding frequencies across life stages to minimize feed wastage and maximize growth velocity.
| Life Stage | Duration | Crude Protein (CP %) | Feed Type & Pellet Size | Feeding Rate (% Biomass) | Feeding Frequency |
|---|---|---|---|---|---|
| Fry to Fingerling Tank Stocking | Day 1 to Day 30 | 32% – 35% CP | 0.8 mm to 1.2 mm micro pellets | 5% of biomass | 4 times / day |
| Biofloc Grow-out Phase | Day 31 to Day 165 | 28% – 30% CP | 2.0 mm to 3.0 mm floating extruded pellets | 2.5% to 3% of biomass | 3 times / day |

5 Golden Aquaculture Rules for High-Density Biofloc GIFT Tilapia
Maintain the Floc Volume Index (FVI) between 25 to 40 ml/L using an Imhoff cone; purge sludge if floc exceeds 50 ml/L.
Maintain Carbon:Nitrogen (C:N) ratio at 12:1 to 15:1 by dosing powdered jaggery or sugarcane molasses whenever TAN rises > 0.5 ppm.
Aeration must be 100% uninterrupted 24/7; install an auto-start ATS changeover diesel generator for instantaneous power failover.
Stock only 100% all-male mono-sex GIFT fingerlings to prevent unwanted reproduction that crashes tank bio-capacity.
