Overview

Alburnoides bipunctatus, the schneider, spirlin, bleak, riffle minnow or bystranka, is a species of brackish and fresh water ray-finned fish belonging to the family Leuciscidae, which includes the daces, the minnows and related fishes. This is a widespread species in Europe.

Schneider (Alburnoides bipunctatus) faces severe threats from habitat degradation and water pollution across its freshwater range. Dam construction, river channelization, and agricultural runoff have significantly impacted water quality and flow regimes in the streams and rivers this species depends on for survival and reproduction.

Threat summary

Frequently asked questions

Why is Schneider classified as Critically Endangered?
Schneider is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Schneider (Alburnoides bipunctatus) faces severe threats from habitat degradation and water pollution across its freshwater range. Dam construction, river channelization, and agricultural runoff have significantly impacted water quality and flow regimes in the streams and rivers this species depends on for survival and reproduction.
Where does Schneider live?
Schneider occurs in Afghanistan, Albania, Australia, Austria, Belarus, and Belgium (plus 29 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Schneider?
The main threats to Schneider are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
