The family of silurid fishes (Siluridae) contains approximately 100 species with presence in Eurasia. Although, the family Siluridae occurs cross much of Europe and Asia, the hot spot of diversity is located in Asia. Four species of catfish are closely related to European catfish: i) Acheloos catfish (Silurus Aristotelis), ii) amur catfish (Silurus asotus), iii) Kunming catfish (Silurus mento), and iv) Soldatov´s catfish (Silurus soldatovi). European catfish (Silurus glanis) originally comes from countries in Central and Eastern Europe, and catchment area of Asian rivers with estuaries in Black and Caspian Sea. European catfish is now invasive in the west and south of Europe. Further, human introduced this large catfish species to other countries. The information about impact of catfish in these new localities is generally lacking. Aquatic ecosystems in these localities are complex and rich in fish species, therefore we may expect lower negative impact of the invasive species here in comparison with the localities such as at Iberian Peninsula in Europe. However, European catfish is a large species with only few competitors, and so the impact must be apparent in any locality. Moreover, there is additional threat of hybridization between the invasive European catfish and closely related native species.
