Abstract

This research has been undertaken to investigate the seasonal fluctuation of planktons and to examine the healthiness of water by analyzing the diversity and density of planktons in Keerat Sagar pond at Mahoba district. Samples were collected from four sites (A, B, C and D) of pond throughout a year from December 2002 to November 2003. After analyzing, it was concluded that sixteen species of phytoplanktons and seventeen species of zooplanktons, belongs to three and four genera respectively were found sufficiently in Keerat Sagar pond and noticed that maximum and minimum density of planktons were present in summer and winter season. The sufficient availability of phytoplanktons and zooplanktons indicated that pond was healthy and fit for the purpose of fish and prawn culture because both types of planktons are the good bioindicator of aquatic pollution as well as water quality status and occupies the first and second tropic level in aquatic grazing food web.
