Abstract

River Kubanni, a major tributary of River Galma, receives both organic and inorganic wastes through run-offs and seepage from residential and agricultural areas of Tundun-Wada, Zaria. Water and phytoplankton samples were collected once a month from three stations on a stretch of the river, for eight months (February, 1994-0ctober, 1994). The physico-chemical parameters and phytoplankton composition were determined and correlated to one another. The distribution and composition of phytoplankton species are affected by variations through fluctuations in environmental variables such as temperature, velocity, transparency, pH, dissolved Oxygen, total alkalinity, total hardness, electrical conductivity and total dissolved matter. Highest dissolved oxygen concentration in February coincided with the minimum water temperature due to the cool harmattan winds. Low alkalinity resulted in low phytoplankton productivity while a rise in total dissolved matter resulted in increase in electrical conductivity and high phytoplankton productivity. The presence of Oscillatoria sp and Euglena sp in station 2 and 3 are indicative of organic pollution in these stations. However, the river stretch is suitable for fish production with respect to water hardness and pH
