Abstract : The pond `Padm-Sarowar’ was controlled by ‘Jain Management’, so collection of any material from the pond was strictly prohibited. However, based on general survey in September, 2007, the pond was classified as a ‘Mixed Type’. The special features of the pond at that time were the macrophytes mainly dominated by red lotus and the carps fishes in central or deeper parts of the pond. In April, 2008, when the pond almost got dried and it was being excavated for renovation, there was no prohibition in collecting the materials. It was this period, when the thick or storage rhizomes and fruits of Nelumbium speciosum Willd. were collected, and their biomass and energetic were determined. Based on these findinas, the nond was found highly productive and economically very important.
