Research interests

Professor Enders is primarily interested in fish ecology, fish and habitat conservation and restoration, and environmental impact assessments of anthropogenic flow and climate changes on fish populations. The focus is on the following issues:

  • The winter biology of freshwater fishes in respect to habitat use and availability, energetic costs of overwintering, survival, and activity patterns
  • Fish passage through fishways and culverts
  • The effects of turbulence on fish behaviour and energetics

The Riverine Fish Ecology Lab of the INRS – Centre Eau Terre Environnement has broad research interests in conservation biology, ecophysiology, fish behaviour and bioenergetics, and aquatic ecology to provide scientific advice for Species at Risk and Fish Habitat Protection. Freshwater fishes are used as research models for experiments conducted in both the laboratory and the field.
