  1. Biofloc-based Vannamei Experiences in India What We Started, How Are We Doing & Where Are We Going? Anil Ghanekar www.ecosecuresystems.com

  2. THE BEGINNINGWater Exchange- The Only Technology • Water-exchange to control water quality • Traditional tidal fed ponds • Shrimp aquaculture’s happy beginning High tide Pond Low Tide

  3. WATER EXCHANGE has PROBLEMS withBiosecurity, Environment & Profitability • Entry of water borne infections – WSSV • Environmental issues- CAA was formed • Water treatment of both raw water and waste water is expensive

  4. How to reduce water exchange? • ALGAE = Sunlight + Nitrogen Reduced water exchange • R.A.S. = Autotrophic Bacteria + Nitrogen Exchange through filters • Biofloc = Heterotrophic Bacteria + N + Carbon Zero exchange

  5. Comparative Setup Costs Between Autotrophic & Heterotrophic Systems Bio-filtration High Cost Biofloc Low Cost 2004 onwards 2007 onwards

  6. Comparative FCRs of RAS And Biofloc Nursery Systems Results with RAS nursery system (2004-2005) Results with Biofloc Nursery systems (2007) (Published in GAA May 2009)

  7. Why Biofloc? • Low Or Zero Exchange • Better Biosecurity • Lower FCR • Better Immunity • Higher Density

  8. Biofloc Nursery • 100 m3 circular tanks • Farm starter feed • No venturi or air lifts • Only aerotube based aeration of 1 Hp/tank • Max stocking density of 10,000/m3

  9. Results With L. Vannamei Juveniles Reared In Low Salinity Biofloc Nurseries & Farms (2012-13) Max 10,000 juveniles/m3 6 hours 95%+ survival Compensatory growth

  10. Biofloc Nursery Reared Juveniles Show Compensatory Growth In The Farm

  11. Biofloc Growout Trials • 1000 m2 Lined Ponds • Central Drain • Aerotube Aeration • Biomass Of 3kg /m3 • 40 Count In 80 Days • 0.3gm Stunted Juveniles Stocked

  12. Biofloc Nursery A Potent Link • Longer Testing Window • Better Immunity • 3 Crops Instead Of 2 Crops A Year • Larger Animals • Higher Farm Survival • Productivity 150%

  13. Hitide Farms • 3 Years • 5 Crops • Excellent For Zero Exchange • Sludge removal is very critical

  14. Biofloc at Research Institutions • C.I.B.A. • Dr. Krishnani from National Institute of Abiotic Stress Management, Baramati • Dr. Kurup and students - Kerala University of Fisheries and Ocean Studies.

  15. FUTURE Less Area Less Water Less Workers Less Power Totally Biosecure Predictable Production Weekly/Daily Supply

  16. Future Solutions Less Area Less Water Less Workers Less Power Totally Biosecure Predictable Production Weekly/Daily Supply High Density Zero Exchange Automation Efficient Technology Zero Exchange High Survival More Ponds

  17. Future Research & Development • Pure Biofloc Nurseries And Farms • Low Density Biofloc With Mixed Systems • Genetics • Specialized Feeds • Molecular Biology • Different Species • Both Biofloc and Vannamei are here to stay
