  • 摘要:We reconstructed Greek fisheries catches from 1950-2003. The landings data recorded by the National Statistical Service of Greece have been compared with those reported by FAO for 1964-2003. For 1969- 2003 we also reconstructed landings derived from rowing boats and coastal boats with engine power <19HP, which are not reported by either dataset. We disaggregated these landings by taxon, based on recent reports of the mean catch per unit of effort of all species caught by different small-scale gears. This allowed estimation of the total Greek marine fisheries landings and comparison with the corresponding FAO data. The reconstructed total landings indicated an average underestimation by 35% (range: 10-65%) of Greek landings based on the reported landings as presented by FAO on behalf of Greece. Except for the taxonomic differences (e.g., the case of Sardinella aurita) and the different taxonomic resolution (e.g., the case of Spicara spp.), which accounted for several discrepancies between the two datasets, the two datasets also differed for most taxa over the period 1964-1969 and for the years 1997 (FAO landings are overreported) and 1998 (FAO landings are underreported). With respect to catches by individual taxa through time, the two datasets generally agreed for the small pelagics and, to a lesser extent, for demersal taxa. The taxa which accounted for the larger and more consistent difference between the two datasets were the large pelagics (swordfish, bluefin tuna and other tuna-like fishes), which were commonly underreported by the national dataset by a factor of 2 for the years following 1990.
