Histopathological changes in liver and gill epithelium of Nile tilapia, Oreochr...
Figueiredo-Fernandes,António; Ferreira-Cardoso,Jorge V.; Garcia-Santos,Sofia; Monteiro,Sandra M.; Carrola,João; Matos,PedroNile tilapia, Oreochromis niloticus, of both sexes were reared in freshwater and exposed to 0.5, 1.0 and 2.5mg L-1 of waterborne copper for a period of 21 days. Liver and gill samples were collected after 21 days of exposure to copper and lesions were analyzed by light microscopy. The main histopathological changes observed in gills exposed to the highest concentration were edema, lifting of lamellar epithelia ...
