Abstract
The study was conducted in a society pond of Gandhibasti village of Abhayapuri, Bongaigaon, Assam to assess the impact of duck droppings on water quality and pond productivity. The pond was integrated with ducks (Anas platyrhynchos) to obtain the benefit of duck litters on the pond productivity and fish growth. The mean dry weight of 80 ducks excreta was estimated as 3.864 kg/ha/day, discharging into the pond. 18,000 fingerlings. Indian major carps along with few exotic carp were stocked in the month of April, 2013. Supplementary feed was also given to the fishes in alternate days to ensure their steady growth. All the studied physico-chemical parameters were found within the permissible limit and the growth of fishes was also satisfactory. The maximum growth was recorded in Catla followed by silver carp, common carp, Rohu and Mrigala.
