Abstract– In the present work an attempt has been made to study the water quality index in selected river system (namely- Harmu river, near Nagadi Block, Ranchi; Swarnarekha river, near Namkum; and Damodar River, near Ramgarh, Dhanbad, Barakar and Bokaro) with a purpose to assess its suitability for fish growth and other purposes. The physico-chemical parameters studied were DO₂, free CO₂, water temperatures, pH, K+, Na+, Ca+, Cl-, SO₄, PO₄ and alkalinity etc. The difference in DO₂ at different sites were statistically significant (P<0.05). Bokaro site of the river Damodar seem to be most suitable for fish growth and development but Ramgarh site was most unfavourable as evidenced by comparable study of water quality index. The details have been discussed in this paper.
