||The 2002 United Nations World Summit on Sustainable Development called for species whose catches had been drastically depleted to be restored to health within 2015. An approach is proposed here to a preliminary classification, based solely on information included in the FAO capture database. Three criteria were used to filter catch data: the trend in recent years, the long-term trend, and the extent of decline in catches over the long term. These were applied sequentially to the data series for species items by fishing area recorded in the FAO capture database. About ten percent of the species items examined matched the selecting criteria. This is the same proportion of stocks classified as “depleted” by FAO based on assessment data although there are differences in the species identified. Reasons for these discrepancies are discussed. The species groups with the highest percentages of species matching the three criteria were Gadiformes, molluscs (excluding cephalopods) and miscellaneous coastal and demersal fishes. Pelagic fishes (including Clupeoids) and crustaceans showed low percentages of depleted resources. Species considered depleted by this procedure are listed by FAO fishing area.
