Alburnus spp (bleak)

Two species of Alburnus are known from the perialpine region investigated in Projet Lac: Alburnus alburnus from Rhine and Rhone catchments, and Alburnus arborella from the Adriatic catchment. It is noteworthy that both species were recorded exclusively within their expected native range.The population of Alburnus arborella from Lake Lugano was originally described as Alborella maxima, Fatio 1882 , considered distinctively larger than A. arborella, Bonaparte 1841 . Buj et al. [146] found that the Lugano population grew indeed much larger than other A. arborella and was also meristically distinct. However, because those authors studied East Adriatic Alburnus populations plus the Lugano population, but did not include populations from the lakes between these regions, it is difficult to interprete their findings with regard to the status of the Lugano population. Currently, Alborella maxima is considered a synonym of Alburnus arborella .
