Carp-SIS Polyculture in Nepal: Present Status and Future Prospects. By Sunila Rai.

  1. 1. Sunila Rai Associate Professor/Assistant Dean (Academics) Animal Science, Veterinary Science and Fisheries Faculty Agriculture and Forestry University Chitwan, Nepal Carp-SIS polyculture in Nepal: Present Status and Future Prospects
  2. 2. Fish production in Nepal Fish production (t) in 2009/10 Fish production (t) in 2010/11 Fish production (t) in 2011/12 Fish production (t) in 2012/13 Aquaculture 28230 30950 32857 36020 Capture fisheries 21500 21500 21500 21500 Total 49730 52450 54357 57520
  3. 3. Aquaculture in Nepal • Growing gradually • Annual growth rate - 10% • Terai and mid hills
  4. 4. Carp-SIS-Prawn polyculture (2008-2011)
  5. 5. Project objectives a. to improve the health and nutrition of women and children through increased intake of nutrient-dense SIS b. to increase household income c. to empower women
  6. 6. Household Income Household consumption to improve nutrition
  7. 7. Partial harvesting of SIS for household consumption and improvement of nutrition level
  8. 8. Project site ChitwanKailali KAILALI
  9. 9. Final harvesting
  10. 10. Household fish production and consumption Total fish consumption (kg/household) byhousehold in 270 days 0 5 10 15 20 25 Carp Carp-Prawn Carp-Prawn-SIS Consuption (kg/household) Total production (t/ha/y) in different farming practices 0 0.5 1 1.5 2 2.5 3 3.5 4 Carp Carp-Prawn Carp-Prawn-SIS Production (t/ha/y)
  11. 11. Bottlenecks Prawn seed: Brought from Bangladesh Expensive High mortality due to long transport Not sustainable because no commercial seed production in the country Niche utilization: 4 carp species might not utilized all niches
  12. 12. Carp – SIS polyculture (2011) Household Income Household consumption
  13. 13. Stocking density (No./ha) of Carp and SIS Species Carp SIS Carp+SIS Rohu 2,000 - 2,000 Mrigal 500 - 500 Silver carp 3,000 - 3,000 Bighead carp 1,000 - 1,000 Common carp 2,000 - 2,000 Grass carp 1,500 - 1,500 SIS - 2,00,000 30,000 Total 10,000 2,00,000 40,000
  14. 14. Total production of Carp and SIS (t/ha/yr) in three treatments (Mean±S.D.) Carp SIS Carp+SIS Carp (t/ha/yr) 3.21±0.34a - 3.72±0.30a SIS (t/ha/yr) - 0.26±0.19a 0.33±0.14a Total (t/ha/yr) 3.21±0.34b 0.26±0.19c 4.05±1.80a Gross Margin (Rs./100m2 ) 1775±713a 269±220b 2556±446a
  15. 15. Periphyton based Carp-SIS polyculture (2012-2013) Household Income Household consumption
  16. 16. Household fish production and consumption
  17. 17. Periphyton based carp-SIS polyculture Removes nutrients from water Adds oxygen in water Quality food (23-26% protein)
  18. 18. In Five Years (2008-to date) KAILALI Horizontal expansion: 2 to 5 districts No. of households: 136 to >1200 No. of direct beneficiaries: 1000 to 8000 Initially implemented districts Expanded districts
