Abstract: The limnological condition of water plays a vital role in aquatic ecosystem. The various physico-chemical parameters of water of pond have been studied during July, 2018 to June, 2019 to find out its impact on fish food production (plankton) of Muntjibpur pond located in Prayagraj district of Uttar Pradesh, India. Various physico-chemical factors such as temperature, transparency, pH, dissolved oxygen, free carbon dioxide, total alkalinity, total hardness, nitrates and phosphate fluctuate within a range conducive to high biological productivity. Total 16 species of phytoplankton and 16 species of zooplankton were recorded. In the present study, the maximum density of plankton was recorded in summer followed by monsoon and winter season. The physico-chemical and biological conditions were also found suitable for fish culture.
