“…The concentrations of Ba, Cd, Mn, Pb, Sr and Zn recorded for muscle were predominantly greater in the present study than in the ones reported by Avigliano et al (2015) for Odontesthes bonariensis in the RdlP and several shallow lakes of the Pampean plain region (Buenos Aires, Argentina). On the other hand, Mn and Zn concentrations in muscle were rather similar to the ones obtained by Vazquez et al (2015) in the same shallow lakes. Furthermore, fish that feed on plankton accumulate Mn in bone tissues to a greater extent than those that feed on benthos (Petkevich 1967), and the concentration of Mn in muscle rarely exceeds 0.5 μg g − 1 wet weight (Eisler 2010).…”

In this study, we analyze the concentration of ten metals in two freshwater fish-the benthic catfish Trichomycterus areolatus and the limnetic silverside Basilichthys microlepidotus-in order to detect possible accumulation differences related to fish habitat (benthic or pelagic), tissue type (gill, liver and muscle), and the river of origin (four different rivers) in central Chile. The MANOVA performed with all variables and metals, revealed independent effects of fish, tissue and river. In the case of the fish factor, Cu, Cr, Mo and Zn showed statistically higher concentrations in catfish compared with silverside for all tissues and in all rivers (p < 0.05). In the case of the tissue factor, Al, Cr, Fe and Mn had statistically higher concentrations in liver and gills than in muscle (p < 0.05). For the river effect, the analysis showed higher concentrations of Cr, Mn and Pb in the Cogoti river and the lower concentrations in the Recoleta river. These results suggest that not all metals have the same pattern of accumulation; however, some metals tend to accumulate more in readily catfish, probably due to their benthic habit, and in liver and gill tissue, probably as a result of accumulation from food sources and respiration.
