Notes
1. Source of capture tonnage: Reference 1 (below).
2. (a) The capture tonnage used for reduction for species categories (except for Norway pout) is estimated using the proportions of total capture used for reduction for the top 20 capture species categories in nine geographical regions for 2007-2011 obtained from Reference 2 (below). (b) The capture tonnage used for reduction for Norway pout is assumed to equal total capture based on Reference 3 (below).
3. Source of estimated mean weights (EMWs) : Study to estimate the global annual numbers of fish caught.
4. (a) The tonnage used for reduction divided by estimated mean weight (EMW) where a mean weight has been estimated for the species category. (b) The figures in italics are extrapolated from the figure not in italics based on the precentage of total reduction tonnage.
5. The capture tonnage for species whose estimated reduction tonnage is nil can be viewed here. These are species which, according to Reference 2 (below), are used 100% for human food uses rather than for reduction in the regions in which they are one of the top capture species.
6. For some species, the proportion used for reduction cannot be estimated from data given in Reference 2 (below) since they are not one of the top capture species in any geographical region. The capture tonnage for species for which capture tonnage for reduction has not been estimated can be viewed here. The total capture for reduction for these species is derived as the total fish capture used for reduction (see note 7) less the total capture for reduction estimated for specific species.
7. The total fish capture tonnage used for reduction is derived as the total fisheries capture used for reduction obtained from Reference 4 (below) less the capture for Antarctic krill. Antarctic krill is a small crustacean which we assume is used entirely for reduction and is the only non-fish species caught for this purpose.
8. (a) Sub totals for species categories based on regional reduction percentages. These are estimated reduction tonnages for species categories in regions based on the proportions of total capture used for reduction for the species category and region obtained from Reference 2 (below). (b) Sub totals for species categories based on extrapolated regional reduction percentages. These are estimated reduction tonnages for species categories in regions based on the proportions of total capture used for reduction for the species category and region extrapolated from Reference 2 (below). The extrapolated reduction percentage is the lowest reduction percentage of all regions for that species category.
