Due to lack of sufficient technical knowledge and training on improved rice-fish culture which is expanding every day, many farmers are not getting optimum results in production. World Fish Center, from the start of the CSISA-BD project took the initiative to develop guideline for improved system for rice-fish culture. It was felt that there is a lack of efficient and skilled trainers and appropriate training materials. Presently there are a number of training manuals published on rice-fish culture by different Government and non-government organization including Department of Fisheries, Bangladesh Fisheries Research Institute, World Fish Center. Based on field experience and with the help of current manuals World Fish Center published this training manual on “Improved Rice-Fish Culture and Dyke Cropping” considering different ecological, socio-economic risks faced by the farmers and present demand as well as evolving problems.
