Abstract

A preliminary survey was carried out during the dry (November – March) season and the wet (April – October) season of the year 2000 and 2002 to determine the physico-chemical limnology of two small ponds in Kaduna, northern Nigeria. The investigated physico-chemical water quality parameters responded to general hydro-climatic, local micro-environmental and anthropogenic influences. The ponds were distinctly different in cationic hierarchy with the pond receiving fish meal dropping having a significantly higher conductivity, carbon dioxide, biochemical oxygen demand (BOD5), nitrate, phosphate, sodium, and potassium than the other pond. However, the levels of the physico-chemical variation among the water quality parameters in both ponds still occurred within the allowable guidelines for most public, domestic and general agricultural uses such as fish culture and livestock productions.
