- Metal contaminants in Largemouth Bass (Micropterus salmoides, Lacépède, 1802) from different originsPublication . Rodrigues, A.M.; Antunes, Paulo; Paulo, Luísa; Pereira, Maria Eduada; Andrade, L.P.The aim of this work was to evaluate the presence of some metals (Cd, Cr, Cu, Fe, Hg, Mn, Pb, Zn) on largemouth bass (Micropterus salmoides) liver and muscle tissue collected in two different areas: section of Tagus River that makes border between Portugal and Spain and in three small irrigation reservoirs located in Tagus River basin. Individuals were weighed and measured. Age were determined by examining fish scales, and sex determined by gonads observation. Samples of dorsolateral muscle, tail muscle and liver were collected to evaluate metal contaminants. We concluded that metallic concentrations of largemouth bass muscle tissues were below the maximum permissible for a safety utilization of theses fishes in human nutrition.
