Abstract
A sizable number of macrophytes growing luxuriantly in Kawar lake, the largest one of its kind in Bihar, are utilized by the native folk for food (Euryale ferox, Ipomoea aquatica, Nelumbo nucifera, Nymphaea nouchali, Nymphaea sp. – a probable hybrid, Cyperus rotundus), fodder (Commelina benghalensis, Cynodon dactylon, Cyperus iria, C. rotundus, Echinochloa colonum, E. crus-galli, Leersia hexandra, Oryza rufipogon, Phragmites karka, Saccharum spontaneum, Schoenoplectus articulatus, S. supinus), fuel (I. aquatica, S. spontaneum), medicine (Centella asiatica, N. nouchali, N. sp.), fish food/duck feed (Ceratophyllum demersum, Hydrilla verticillata), decoration (N. nucifera), worship (N. nucifera, N. nouchali) etc. Besides fulfilling household requirements, the sale of certain macrophytes for medicine (flower of N. nouchali), fish food (whole plant of C. demersum and H. verticillata) and multipurpose materials (C. iria, P. karka) boosts up their economy. These aquatic resources need optimum commercial exploitation for the upliftment of poor people residing around the lake.
