Kelleher, K. Discards in the world’s marine fisheries. An update. FAO Fisheries Technical Paper. No. 470. Rome, FAO. 2005. 131p. Includes a CD-ROM. Abstract This study provides an update of the quantity of discards in the world’s marine fisheries based on a fishery-by-fishery approach. The weighted discard rate is estimated at 8 percent (proportion of the catch discarded). Based on this discard rate, in the 1992-2001 period, yearly average discards are estimated to be 7.3 million tonnes. Because of the different method used in the current estimate, it is not directly comparable with the previous estimates of 27 million and 20 million tonnes. |
