- Fish production in Nepal has been gradually increasing annually, with aquaculture growing at 10% per year. A carp-SIS-prawn polyculture project from 2008-2011 aimed to improve nutrition, increase income, and empower women. It showed higher fish production and household consumption from adding SIS and prawn to carp culture. However, importing prawn seed was unsustainable. - A carp-SIS polyculture from 2011 showed higher yields and profits than carp or SIS monocultures. Periphyton-based carp-SIS polyculture from 2012-2013 further increased production and consumption. The project has now expanded to benefit more households across multiple districts. Ongoing
