Dirk Algera



I am interested in how and why human interactions affect fish and wildlife. My research involves empirical studies, meta analysis, and policy assessment to contribute to scientifically sound, evidence-based fish and wildlife conservation and management.

Research Interests

Fish behaviour, the impacts of hydropower on fish and aquatic organisms, catch and release angling science, imperilled species management, invasive species biology and management, sustainable aquaculture.
