Abstract: Studies on the aquatic insects of some swamps in Rajshahi University campus were made for a period of 12 months from November, 2001 to October, 2002. The insect population mainly consists of Coleoptera, Diptera, Hemiptera and Epimeroptera. The highest number of insects were recorded during November and December, 2001 and from February to May, 2002. A total of 18 genera under 13 families and 4 orders were identified. Some hemipterans (Corixidae, Gerridae, Nepidae and Hydrometridae) and dipterans were surface dwellers, Notonectidae of order Hemiptera were middle dwellers and others were bottom dwellers. The investigation of natural fish production was also considered. From the above investigation, it is concluded that the insect population in swamps was very high and it can be used as natural food for fish culture
