The ninth session of the Committee on Aquaculture (CAQ) of the General Fisheries Commission for the Mediterranean (GFCM) was held in Marrakech, Morocco, from 24 to 26 February 2015. The session was attended by delegates from GFCM Members, observers from the International Organisation for the Development of Fisheries in Eastern and Central Europe (Eurofish), the Centre for Marketing Information and Advisory Services for Fishery Products in the Arab Region (Infosamak), and the International Union for Conservation of Nature (IUCN), as well as representatives of the Food and Agriculture Organization of the United Nations (FAO) and the GFCM Secretariat. The agenda also included a special session of the Information System for the Promotion of Aquaculture in the Mediterranean (SIPAM), which examined aspects related to online consultation of GFCM aquaculture data. During its ninth session, the Committee reviewed its intersessional activities and the outcomes of its working groups, and discussed important issues regarding its functioning and reorganization in light of the ongoing amendment of the GFCM legal and institutional framework, with a view to proposing a new reference framework to the next annual session of the GFCM. The Committee also endorsed the conclusions of the Regional Aquaculture Conference “Blue Growth in the Mediterranean and the Black Sea: developing sustainable aquaculture for food security” (Italy, December 2014), agreed upon actions towards the development of national aquaculture platforms in order to support the GFCM Aquaculture Multistakeholder Platform (AMShP) and formulated advice on the following aspects: (i) sustainable management of coastal lagoons; (ii) use of regional indicators to monitor sustainable aquaculture development; (iii) use of environmental monitoring programmes (EMP); (iv) aquaculture stock enhancement; and (v) data reporting for the transmission of information on aquaculture production centres. Finally, the Committee adopted its work programme for 2015–16.
