Inland freshwaters with a greater variety of fish species (biodiversity) have higher-yielding and less variable fisheries according to a new study from the University of Southampton and the International Union for Conservation of Nature (IUCN).
At least two billion people depend directly on inland freshwaters, such as lakes, rivers and wetlands, for the provision of food. However, despite thousands of freshwater species contributing to food security, the relationship between biodiversity and yield remains poorly understood.
