Abstract

The contributions presented at the European Inland Fisheries Advisory Commission Symposium on The Effects of Fisheries Management Practises on Freshwater Ecosystems in 2002 are reviewed. The principal mechanisms of inland fisheries management concentrate on four categories: fish stock enhancement (stocking and introductions); rehabilitation and habitat manipulation for fisheries purposes, including biomanipulation; fisheries regulations; and conservation and protection of fish and fisheries. The negative and beneficial impacts of these activities are summarised and options for improving the outputs of fisheries management practices to accrue wider benefits to society are discussed. Wider stakeholder participation and a shift from traditional fisheries towards ecosystem-based management approaches are the main mechanism proposed. This calls for new management tools to cater for legitimate human demand for water abstraction, hydropower generation and effluent disposal, as well as alternative commercial use of water bodies such as bathing, boating and tourism, in addition to fisheries exploitation and conservation needs.
