A study was undertaken on duck farming in a North-eastern part of India (Assam), representing almost all the agro-climatic zones. Five districts were selected, one from each agro-climatic zone except for the hill area. Twenty-five duck farmers from each district, a total of 125 in all, were selected on the basis of flock size. Results of the study in respect of socio-economic status of the farmer, demographic distribution, husbandry and feeding practice, production performance, incidence of diseases, mortality pattern and health protection programmes, marketing, finance and costs and returns from the flocks are highlighted.
