“…The Danubian whitefin gudgeon ( R. vladykovi ) and the Gobio taxa of this region show high similarity in scale size. The former species is the dominant gudgeon in lowland sections of the Middle Danubian river system (Eros, 2007; Kottelat & Freyhof, 2007), while Gobio species prefer the slow flowing hilly streams in this area (Takács et al., 2008). Among the analysed Gobionid species, the sole stagnophilic species, the stone moroko ( Pseudorasbora parva ) (Table 1), has the largest scales.…”

“…Gobionid species changes along the submontane-piedmontlowland gradient, and these changes also manifest in significant changes in scale sizes (Figure 3b).

It has long been recognized that presence–absence, localisation, size, number and shape of fish scales can be important taxonomic features. Although there are some notes on the relationship between scale morphology and ecological needs, in the absence of a sufficiently large and detailed database, the morphological variability of fish scales and the factors responsible for this variability have not yet been explored in detail. For this reason, a database—which contains the shape and relative size data of 193 freshwater fish taxa of 14 orders, originated from five biogeographic realms—has been built. Database analyses showed that both the scale shape and relative size are proper taxonomic indicators. They can be used to separate higher taxonomic categories (e.g., orders), and by the simultaneous analysis of shape and size scale morphology, we showed increased sensitivity for species‐level detachments. Our results suggest that while both the shape and the size of the fish scales are genetically determined, they are also useful descriptors of the niche segregation (habitat use, flow preference) of close relative species. Scale morphology is a promising additional tool to specify the environmental preferences of lesser known or close relative recent and extinct fish species. And also can be of great help in such cases when only the scales are available for taxonomic identification, for example, in the research field of archaeology and palaeontology.
