Abstract: 
The development of nonlethal methods for the monitoring of environmental contamination isessential to minimize the negative effects on studied species and communities. Fish scales and fin clips canbe used as nonlethal indicators of water quality given that they are in direct contact with the environment andcan accumulate high concentrations of metals and trace elements. Fin clipping causes minimal harm to fishand it does not affect fish growth or survival. In this study, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Znconcentrations were measured by inductively-coupled plasma mass spectrometry (ICP-MS) in scales, fins,and muscle of common bream (Abramis brama), white bream (Blicca bjoerkna), wels catfish (Silurusglanis), northern pike (Esox lucius), and pikeperch (Sander lucioperca) from the Danube River. The analysisshowed a positive correlation for Hg between scales and muscle in pikeperch. Anal fin and muscle werepositively correlated in white bream for Hg, in wels catfish for Cu, and in northern pike and pikeperch for As.The results suggest that scales and fins have a potential to be used as indicators of muscle tissuecontamination with As, Cu, and Hg, depending on species’ecological traits.
