Semester hours
Lecturer (assistant)
Offered in
Wintersemester 2022/23
Languages of instruction


The lecture covers the following topics in applied fish ecology:

- Discussion of impact models (e.g. drivers and pressures - DPSIR, cascade models)
- Overview of the status quo of running waters (global, EU/Alps, Austria)
- Overview of major human pressures/related impacts
- Discussion of different types of human impacts
- Discussion of case studies


#1 - Introduction

#2 - Impacts due to hydro-power production (Hydro-power use: run-of-river-/diversion-/storage power plants)

#3 - Residual flow/water abstraction (minimum flow requirements)

#4 - Hydropeaking (magnitude, frequency, duration, effects on hydro-morphology)

#5 - Impoundments & reservoir flushing (flow patterns, sediment transport etc.)

#6 - Morphological impacts (effects on physical environment, riverine habitats, floodplains, vegetation/land-use etc.)

#7 - Land use change (forms of land use, nutrients etc.)

#8 - Organic impacts (organic pollution, toxic substances etc.)

#9 - Multiple impacts (interactions of pressures etc.)

Previous knowledge expected

Basic knowledge in hydrobiology & fish ecology

Objective (expected results of study and acquired competences)

1. Get an overview of fish-ecological conditions in Austrian & European rivers.
2. Evaluate the impacts of human activities on running waters.
3. Lern and discuss methods for assessing and improving ecological integrity.
