    Background. A wide range of morphological anomalies, including abnormalities in scale shape and structure, have been described from a large number of fish species worldwide. Quite often, such reports linked the observed abnormalities to the quality of aquatic environment. The presently reported study was initiated to explore and categorize the abnormalities found in the scales of seven freshwater fish species of Czech Republic: Ctenopharyngodon idella (Valenciennes, 1844); Gymnocephalus cernua (Linnaeus, 1758); Hypophthalmichthys molitrix (Valenciennes, 1844); Hypophthalmichthys nobilis (Richardson, 1845); Leuciscus idus (Linnaeus, 1758); Perca fluviatilis Linnaeus, 1758; and Sander lucioperca (Linnaeus, 1758). The observed abnormalities are discussed in the context of contaminated aquatic environments with the intention to understand the aetiology of the abnormalities
