A REVIEW ON THE BIOLOGICAL RESOURCES OF GANGA
As its water is used for human and cattle consumption, power generation, fish processing and irrigation and for pilgrimage, the Ganga River in northern India is of great importance. The upper Ganga River has known a total of 40 zooplankton species, four crustaceans, 15 molluscs, 51 insects, 83 fish, 12 freshwater turtles, two crocodiles, 48 aquatic birds and two species of mammals. The river has been under constant threat of sewage and industrial waste contamination, dead body disposal, deforestation, excessive fertilizer usage and pesticides, programs for bathing, pilgrimage and water production.The river's contamination has become a matter of concern for everyone. Any alteration in the aquatic ecosystem can alter the structure of the biotic population and its composition. The government of India has implemented an Action Plan for the biological conservation of the Ganga River. For example, several departments, the Central Ganga Authority, several research institutions, government and non-governmental organizations have done significant work on different projects. Local involvement in different programmes has significantly contributed to the ecological conservation of the Ganga River. This paper provides lists of species and addresses significant resource management concerns in the upper Ganga River.
