3. Aquaculture in Nepal
• Growing gradually
• Annual growth rate - 10%
• Terai and mid hills

4. Carp-SIS-Prawn polyculture
(2008-2011)

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

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
