Abstract : Biodiversity of river Gomti is heavily affected by pollution. Planktons are important biological parameters to access the pollution level. Zooplanktons are the source of food for higher organism and phytoplankton play important role in biosynthesis of organic material and influence the river ecosystem, aquatic food chain and water characteristic. The biological productivity as ecological indicator to identify the ecological quality of river Gomti. The phytoplankton density fluctuated maximum in between the range of (140-900 In/l) during monsoon season and minimum (40-140 In/l) during winter season. Zooplanktons were reported to be highest (168-220 In/l) during winter and lowest (114-155 In/l) during summer season. During study period the total of phytoplanktons (17 sp.) and zooplanktons (10 sp.) were noticed during different seasons. Present study concluded that seasonal differences of planktons density will help in further planning of water management and their use for beneficial purpose like agricultural, drinking for mankind.
