This study presents the results of a microsatellite and allozyme analysis on natural populations of the gudgeon (Gobio gobio) located in a pollution gradient of cadmium and zinc. Differences among contaminated and reference populations were observed at 2 allozyme loci, as well as a relationship between the fish condition factor and glucose-6-phosphate dehydrogenase genotypes, the locus that showed...
This study assesses the applicability of a sentinel fish species as a biomonitor of metal pollution. Gudgeon (Gobio gobio) were collected from 14 sites in metal polluted lowland rivers in Flanders, including a clear Cd and Zn pollution gradient. Fish tissues were analysed for Cd, Cr, Cu, Ni, Pb and Zn. Metal levels in organs were related to levels in water and sediment. At some sites Cd and Zn levels...
