| Impact Description | In the Turkish Lake Egredir, Sander lucioperca was introduced in 1955 and from 1961 it became an important species in commercial fisheries in the lake. The introduction also had the result that 5 out of 9 indigenous fish species disappeared, among these three species of Phoxinellus, two of which were endemic to Lake Egredir. Consequently, these two species must now be considered extinct worldwide. |
