Modern Distribution of Armored Catfishes (Siluriformes: Loricariidae) in Central Vietnam

Resumo

The modern distribution of South American armored catfishes (Loricariidae) is studied in three provinces in Central Vietnam. In the investigated area, representatives of the genus Pterygoplichthys occur, and at present they have moved into all main river basins. During the last 2–5 years, alien species have entered into many water bodies isolated from the places of their first discovery by natural and manmade barriers. This indicates the important role of the human factor for the expansion of loricariids in the region.
