ASSESSMENT OF PHYSICO-CHEMICAL PARAMETERS OF SELECTED WETLANDS OF JAMMU DISTRICT WITH REGARD TO AQUATIC ORGANISMS

The study was conducted to Analysis the Physicochemical parameters of wetlands of Jammu district and to know the survival status of aquatic organisms found in the water of all these wetlands of Jammu district during the period from January 2020 to March 2020. Over exploitation of fisheries resources and human activities are gradually hampered the aquatic environment of the wetlands. For existence and conservation of aquatic resources, it is essential to investigate the water quality and surrounding environment of the wetlands of Jammu district. The results of the study showed that Some water quality parameters lies in permissible limit except Dissolved Oxygen, pH, Nitrate, Alkalinity were not within the tolerance limit of IS 2296:1982 of class D prescribed by Bureau of Indian standard for inland surface water for fish culture and wildlife and IS 13891:1994 prescribed by Bureau of Indian standard for fresh water fish culture. Except Gharana wetland water quality of other wetlands such as Pargwal, Makhwal, Mansar and Surinsar wetlands were found not suitable for the survival of Aquatic Organisms due to higher concentration of pH, Nitrate and Ammonical Nitrogen and lower concentration of Dissolved oxygen and Alkalinity which were not within tolerance limits of both standards IS 2296:1982 of class ‘D' and IS 13891:1994 prescribed by BIS for fish culture and wildlife. Some other reasons which are responsible for the polluted water quality of all these wetland are due to agrochemical pollution, presence of toxic chemicals, contamination of water by human activities like dumping of waste, throwing of garbage, washing clothes and bathing in the wetland.
