A Combined Field Study of Barbus (= Puntius) Nigrofasciatus GÜNther (Pisces, Cyprinidae) and Water Chemistry of Its Habitat in Sri Lanka

A COMBINED FIELD STUDY OF BARBUS (= PUNTIUS) NIGROFASCIATUS GÜNTHER (PISCES, CYPRINIDAE) AND WATER CHEMISTRY OF ITS HABITAT IN SRI LANKA by K. KORTMULDER1, E. J. FELDBRUGGE1 and S. S.
