Study of water quality using of physico-chemical parameters of two perennial fish ponds of Darbhanga

Abstract

Darbhanga is known as city of ponds. The current investigation was undertaken the study of the physico-chemical conditions of two perennial fish ponds- Harahi Talab and Maharani Pokhar of Darbhanga city. Present study revealed that physico-chemical parameters were comparatively higher of Harahi Talab to other pond, Maharani Pokhar. The water samples were analyzed for water temperature, transparency, TDS, pH, free CO2, chloride, carbonate, bicarbonate, magnesium, dissolved oxygen (DO) and biological oxygen demand (BOD). Higher value of physico-chemical parameters BOD, is considered to be sewage water pollution indicator for eutrophication and it also lower down the fish production.
