Abstract: Studies on the limnology of a fishpond of Rajshahi University campus were made over a period of 12 months between January-December 2002. Fluctuations of some physico-chemical parameters were noted. This pond was found to be of eutrophic in nature with slightly acidic to alkaline pH, with high bicarbonate content. Diurnal change of water temperature was also observed. Like other stagnant water bodies the thermal stratification occurs in this pond.
