Comparison of theWest, Central and Southern African
LME Fisheries
The DOI for all three LMEs, before adjusting for MSY or
subtracting 10 per cent for fish nurseries, totals an estimated
US$ 23.35 billion (see appendix D).
122
The GCLME fisheries,
with an estimated US$ 18.8 billion DOI, provides the bulk of
the total DOI, followed by the CCLME fisheries with US$ 4.1
billion and then the BCLME fisheries with US$ 517 million
(Figure 17; all figures include IUU catch). The GCLME ocean
region is 2.2 times the size of the CCLME which would
perhaps explain the larger DOI, but the GCLME’s estimated
per hectare DOI of US$ 74.3 is still twice that of the CCLME per
hectare impact of US$ 35.9.
123
The GCLME DOI figure is about
31 times that of the BCLME even though the GCLME catch
of approximately 1.59 million tons (2003) is only about 1.6
times that of the BCLME catch of 0.96 million tons (2006).
124
Furthermore, the DOI estimates for Angola’s fisheries comes
to $105 million in the BCLME study versus over $2.5 billion
(not adjusted for MSY levels or double-counting of fish
nurseries) in the GCLME study. These massive differences
elucidate a disparity in valuation methodologies.
CCLME, $4,040.8
BCLME, $517

Figure 17:
The Direct Output Impact (DOI) from each of
the west, central and southern African LME fisheries in US$
million per year. Not adjusted to Maximum Sustainable
Yield (MSY) levels. The value of fish nurseries has not been
subtracted from the total. The DOI is chosen as a measure
for comparison in Figure 17 because the BCLME study does
not examine MSY levels nor deduct for the impact of fish
nurseries (a coastal ecosystem review is not part of the study).
The GCLME and CCLME values include the IUU catch values.
