The recordings in this collection are the annual progress reports of NACA’s regional lead centres in India, Thailand, China and the Philippines, plus a summary of NACA’s progress over the past five years and a special address by Professor E.G. Silas. The presentations were made at the 22nd NACA Governing Council Meeting in Cochi, Kerala, from 9-11 May 2011, which was hosted by the Government of India. The Governing Council is NACA’s peak policy body, which meets annually to review the organisation’s activities and set priorities for the year ahead. Collectively NACA’s 18 member states produce more than 90% of global aquaculture by volume, which now represents around 50% of the global food fish supply.
