Endangered river fish: threats and conservation options
Colorado River in the Grand Canyon by Craig Paukert.

Globally, riverine fish face many threats associated with human activity including altered hydrology, migration barriers, fisheries exploitation, riparian and flood plain alteration, environmental change, and introduction of invasive species. Collectively, these threats have made riverine fish some of the most threatened taxa on the planet. This special issue explores the range of threats facing riverine fish, with a focus on species or large river systems that are particularly imperilled. In addition, it examines various alternatives available to conserve and restore endangered river fish populations and riverine ecosystems (e.g.use of aquatic protected areas, co-management and stakeholder engagement, refinements in flows, restoration of connectivity, control of non-native fishes). Contributions span large river-resident and diadromous fish species which are not only listed as endangered by federal governments or international organizations, but have been defined by local and regional agencies as imperilled. Case studies from around the globe integrate the science and practice of river fish conservation and environmental management.
