Abstract

Bakhira Lake is the largest man‐made lake of Eastern Uttar Pradesh. It is utilized for Boro (coarse paddy) cultivation, irrigation and fishing by poor village farmers. Hydrographical features, qualitative and quantitative composition of the macro‐zoobenthos, and the physico‐chemical characteristics of the bottom water and sediment were studied from October 1976 to April 1977.

Molluscs, insects, ostracods, annelids, nematodes and crustaceans are the main groups of zoobenthos. Molluscs together with insects dominate the benthic fauna (95.2 to 96.4% of numbers). The benthic density varied from 273 to 517 individuals/m^2^. Average density of macro‐zoobenthos is more or less inversely related to the total alkalinity of the bottom water. Molluscs showed a positive correlation to temperature and a negative correlation to insect density.
