Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
The Ebro Barbel (Luciobarbus graellsii) is a freshwater fish native to river drainages in northern Spain. L. graellsii is a sportfish in Europe. The history of invasiveness for L. graellsii is not documented. L. graellsii has become established in Italy. It is theorized that this species could detrimentally impact the native barb, Barbus tyberinus, which is already threatened by another introduced Barbus sp. Negative impacts on B. typerinus from the presence of L. graellsii have not been scientifically documented. The climate match with the contiguous United States is medium. Six States had high individual climate scores. The certainty of assessment is medium. Records of introductions and establishments were found and there is some information on potential impacts. However, no records of documented impacts were found. The overall risk assessment category is uncertain.
