Freshwater fish biodiversity in Austria and Germany

Overview

Freshwater fish biodiversity in Austria and Germany is facing significant challenges due to human-driven factors such as climate change, pollution, and migration barriers. In Austria, more than 45 percent of fish species are considered endangered, prompting conservation efforts like the targeted breeding and reintroduction of the Sterlet.

Ecological assessments in Germany indicate that 43 percent of native freshwater fish and jawless fish species are threatened, with migratory species like eel and smelt under particular pressure. Conversely, some species such as the brook lamprey and bullhead have shown status improvements. In Austrian alpine lakes, while native fish populations remain under pressure, noble crayfish populations have shown positive developments in several areas.
