dc.description.abstractThis experiment has clarified the ultrastructural pathology, by scanning (SEM) and transmission electron microscopy (TEM), induced by 1- naphthyl-N- methylcarbamate (carbaryl) in the gills of juvenile goldfish (Carassius auratus Linneaus). Carbaryl is a low toxicity pesticide commonly used in forestry and agriculture and for controlling aquatic weeds and crustacean predators of shellfish, and has been known to cause gill damage in fish and clams. A variety of cellular changes were observed after exposure of goldfish for 96 h to a sublethal dose of 10 mg carbaryul of water. SEM revealed secondary lamellar fusion, distortion, thinning, and mucus release. TEM responses included enlargement of subepithelial lymphatic spaces and mitochondrial disruption and distortion of the lamellar covering epithelium. Pillar cells became detached and chloride cells were vacuolated. Fish were able to withstand these changes in subacute experiments due to redundacy in gill surface area.es
