Abstract: Effect of the cypermthrin on the ultra structure (SEM) studies of the gill tissues of fish Labeo rohita. The fish were exposed for 24, 48, 72 and 96 hours in 10% and 20% sublethal concentration of 96 h LC 50 of cypermthrin (0.0037 ppm). Exposur of fishes to 10% and 20% sublethal concentrations of cypermethrin caused several changes in the gills: secondary lamellar fusion, disintegration of gill lamellae, intensive vasodilatation of the lamellar vascular axis.
