The twenty-fourth session of the European Inland Fisheries Advisory Commission (EIFAC) was held in Mondsee, Austria, from 14 to 21 June 2006, in concomitance with a Symposium on Hydropower, Flood Control and Water Abstraction: Implications for Fish and Fisheries. The session reviewed EIFAC's activities since 2004 in the fields of fishery biology and management, aquaculture, protection of the aquatic environment, and social and economic issues. EIFAC revised and decided its future programme of work, in particular the activities which should be carried out until the next session of the Commission in 2008. The twenty-fifth session will be preceded by a Symposium that will focus on interactions between socio-economic and ecological objectives of inland fisheries, commercial and recreational, and aquaculture.
