This chapter details the findings of two methods which were used to rankissues: (a) consensus opinions obtained at the Workshop during discussion sessionsin October 1996 and (b) a Post-Workshop Survey of all participants in September–October1997.* University of Western Sydney Macarthur, PO Box 555, Campbelltown, New South Wales 2560, Australia.† Network of Aquaculture Centres in Asia–Pacific (NACA), PO Box 1040, Kasetsart Post Office, Bangkok10903, Thailand.93
