First crop/pre-kharif/spring rice (February, March-June, July) is dying down in Manipur due to many factors such as non-availability of suitable variety, susceptibility to lodging and sprouting because of rain during harvest, meager irrigated area, submergence of shallow lake areas due to Loktak Hydel Power Project, etc. and improper land preparation due to lack of time. A study was conducted during 2014 to 2016 at twelve farmers’ field under refined SRI method (without ploughing, fertilizer or manure). After the harvest of fish in the month of February, rice nursery was raised and after the harvest of rice, fishes raised from the previous years in a separate nursery pond was stocked in the ratio of grass carp (500 no.), silver carp (500 no.), rohu (1000 no.), mrigal (1000 no.) and common carp (1000 no.). This practice has enabled the farmers to earn an average annual gross income of Rs. 348850/ha giving a B: C ratio of 2.56.
