Complete Production Cycle Summary
Hatchery Phase
Egg to 1-2cm juvenile
Tank Grow-out
Juvenile (1-5g) to market (200-300g)
Market Weight (Fresh)
16-22cm length | ~40g dried
Survival Rate
At 1-2 ind/m² density
Growth Rate
Juveniles (1-5g) reach market size (200-300g) in approximately 6 months under optimal conditions.
Feeding Behavior
Detritivores - feed on organic matter in sediment. Supplemental feeding with rice bran (0.2-0.5 kg/m² bi-weekly) enhances growth.
Reproduction
Spawning typically occurs in warmer months. Females release ~1.9 million eggs per spawning event.

Revenue & Market Prices
CRITICAL: Use REAL Market Prices!
Many calculators use inflated prices (Rs. 1,500/kg), leading to unrealistic projections. NARA 2023 case study shows actual farm-gate price: Rs. 975/kg.
📘 NARA: Rs. 975/kg (PROVEN) | Market: 950-975
Processor export: USD 6-8/kg = Rs. 1,840-2,460
💡 Export gets 15% tax rate (vs 30% domestic) = Massive savings!
🎯 Export Tax Incentive (CRITICAL ADVANTAGE!)
Standard corporate tax rate on domestic revenue
Reduced rate for foreign exchange earners!
- 100% domestic sales = Pay Rs. 3.0M tax (30%)
- 100% export sales = Pay Rs. 1.5M tax (15%)
- Savings from exporting: Rs. 1.5M!
🏦 Financing Options & Government Support
