Many rivers, lakes and other inland waters have been modified and degraded by human activities. Rehabilitation of degraded systems and mitigation of impacts of ongoing stresses are needed to preserve ecosystem services and fisheries, and are of a high priority if the aquatic biodiversity of inland waters is to be conserved. The new FAO Technical Guidelines for Responsible Fisheries, Inland Fisheries - Rehabilitation of inland waters for fisheries, recommend to apply methods available for the rehabilitation and mitigation to restore habitat diversity in an aim to benefit fish and fisheries.
