Plankton diversity and density in Pandey Taal of Gonda district, Uttar Pradesh, India

The importance of the plankton is well recognized as these have vital part in food chain and play a key role in cycling of organic matter in the aquatic ecosystem. The inadequate knowledge of plankton and their dynamics is a major drawback for the better understanding of the life process of fresh water bodies. In the present investigation, total 23 species of phytoplankton and 22 species of zooplankton were also recorded. Bimodal pattern of seasonal variation of plankton was observed with a primary peak in the month of July and secondary peak in January. The physico-chemical and biological conditions were found suitable for fish culture and agriculture.
