Figure 7.12: Plots from Baird and Wood (2010) of the areas of each BOMEC Class (top), the fishing footprint up to
2004/05 shown in Figure 7.8 (centre), and percentage of each BOMEC Class area covered by the fishing footprint
(bottom).
Table 7.3: Estimated area of each BOMEC class (within the outer boundary of the EEZ), the minimum and
maximum values for the trawl footprint in each, and cumulative footprint over the 16 years studied by Baird and
Wood (2010).
