This document contains nine papers on cage aquaculture including a global overview, one country review for China, and seven regional reviews for Asia (excluding China), northern Europe, the Mediterranean, sub-Saharan Africa, Latin America and the Caribbean, North America and Oceania, all of which were presented during the FAO Special Session on Cage Aquaculture - Regional Reviews and Global Overview at the Asian Fisheries Society Second International Symposium on Cage Aquaculture in Asia (CAA2), held in Hangzhou, China, from 3 to 8 July 2006. Each review, by geographic region, gives information about the history and origin of cage aquaculture, provides detailed information on the current situation, outlines the major regional issues and challenges and highlights specific technical, environmental, socio-economic and marketing issues that cage aquaculture faces and/or needs to address in the future. The review recognizes the tremendous importance of cage aquaculture today and its key rote for the future growth of the aquaculture sector. The global overview discusses the available data on cage aquaculture received by FAO from member countries, summarizes the information on cultured species, culture systems and culture environments and explores the way forward for cage aquaculture, which offers especially promising options for multitrophic integration of current coastal aquaculture systems as well as expansion and further intensification at increasingly offshore sites.
