Résumé
Continental aquatic ecosystems are particularly affected by human activities including the modification or elimination of habitats because of territorial planning works, pollution from different sources, and overfishing. The consequences of these activities, now amplified by population growth and increasingly heavy pressure on natural resources, endanger ichthyological fauna the world over. Long spared these impacts, Africa is now feeling their effects even though pollution, for instance, is still relatively limited in extent.
