Population [top]

Population:This species is now Extinct. The extinction is thought to have happened after the 1950s but the actual date of extinction cannot be identified due to the introduction of A. escherischii into the lake and the potential identification of this alien species as the native one.

Threats [top]

Major Threat(s): The introduction of Sander lucioperca (in 1955) appears to be the main reason for the extinction of this species. Overfishing also contributed to declines and if any individuals had survived, it is likely that alien Alburnus escherischii would have hybridized with the native species.
