| Summary: | Scardinius is a genus of ray-finned fish in the Cyprinidae family commonly called rudds. The common rudd
(Scardinius erithrophthalmus) is a bentho-pelagic freshwater fish that occurs mainly in nutrient-rich, well vegetated
lowland rivers, backwaters, oxbows, ponds and lakes and it is widespread in Europe and middle Asia. It has a medium
length of 20-30 cm, but it can reach 50 cm. The classification of cyprinids has always been controversial the morphological
traits have an unclear homology this led to the idea that the recognized monophyletic groups are surely misinterpreted. This
paper aims to assess the current level of molecular data regarding Scardinius genera. Some of the molecular data obtained
for Scardinius genus is from DNA barcoding studies on fresh water fishes, but studies regarding this genus and Cyprinidae
family used mitochondrial genes like cytochrome b (cyt b) and cytochrome oxidase (CO), but nuclear genes or nuclear
microsatellites were also used. We found that molecular data exists for both nuclear and mitochondrial genes, but this genus
wasn’t studied separately and as many of the researchers suggest more taxonomic studies are required in order to solve the
uncertainties within it. |
