چکیده

An attempt has been made to evaluate pollution status and aquatic bio-resources of the Moirang river near its mouth in the Loktak Lake. The river water is considered polluted as it has high concentration of free CO2 (14.8 mg/l), nitrite-nitrogen (0.040 mg/l), inorganic phosphorus (0.107 mg/l and faecal coliform bacteria (162/100 ml). Aquatic bio-resources of the river include 24 species of fishes representing 20 genera of 13 families and 16 species of macrophytes representing 14 genera of 9 families. The floral and faunal compositions of the river were mostly widely distributed forms that can survive in polluted environments. Fishery potential and conservation strategies of the river are discussed.
