Abstract
The microscopic structural details of gills inrnfour fresh water fishes collected from an aquatic body (Bheema river) has beenrninvestigated in relation to some Physico-chemical characteristics of water.rnAmong the four fishes investigated, the fish Labeo rohita exhibited somerndegenerative changes in the gill filaments whereas the other three fishes suchrnas Channa punctatus, Notopterus notopterus and Tilapia mossambicus havernnormal structure, which indicate that the water is providing proper ecology forrnsurvival and good health condition of three fishes harboured in the aquaticrnbody. The changes observed in the gill of Labeo rohita may be because ofrnits sensitivity to some of the unwanted factors present in the aquatic mediumrnwhich may be specific to the fish.
