The data on food fish supply (total and per capita) presented for the world in the Overview section of Part 1 (Tables 1 and 2) differ from those presented in the Fish utilization section of Part 1 (Table 8) owing to different time frames. The source of the more detailed figures reported in the latter is the FAO Fisheries Circular No. 821, Rev. 6. [Laurenti, G. (comp.) 1961-1999. Fish and fishery products: world apparent consumption statistics based on food balance sheets], which was compiled using statistics held in the FAO fishery statistical database in August 2001. The world total data presented in the Overview (Tables 1 and 2) are based on more recent production figures of March 2002, which also incorporated historical revisions. The food fish supply data in Tables 1 and 2 are indicative and may be subject to further revision when the food balance sheets are updated.
