Nature and human race have been ruthless to the River Dolphins and there has been mass exodus of dolphins from their original homes.Consquently their numbers have been dwindling over the years. The number of dolphins this year has come down to 34, six less than last year, studies reveal. Before 1980 the river dolphins, also called 'Sasu' were quite abundant in the Ganges and the Brahmaputra river system and their population estimated to be 6000.
There is an alarming decline in the number of dolphins, ranging from 10 to 15 per cent per annum, the study says. A programme called 'Save River Dolphin Programme' was initiated by WWF India and 'Nature Exploration Group to look into the problem. The recent study revealed that most of the dolphins have moved upstream leaving the old homes in and near Narora Barrage Reservior. Bureau Report.
