Macrozoobenthos are the best indicators of the stress in the aquatic ecosystem. Distribution of macrozoobenthos is determined by a number of factors such as physical nature of the substratum, depth, nutritive content of the water body. Present study was conducted to assess the diversity of macrozoobenthos of Khyra Mandir Taal of District Gonda, U.P. during July 2014 to June 2015. During the present investigation a total number of 21 genera of macrozoobenthic fauna were recorded from one year's investigation. Observations revealed that phylum mollusca acquires dominant position with 42.85% of total faunal composition while phylum annelida constitutes 33.33% and comes on second position whereas, least faunal abundance was found from phylum arthropoda which contributes 23.80%.
