Table 10 refers specifically to the areas designated in Figure 50. The table shows SP-1, SP-2 and SP-3<br />
and the expected effort for each of the four fisheries for which we had adequate data:<br />
a) Our historical data is from 2008 to 2010<br />
b) We have the number of vessels in each sector for 2009 and 2008 but for 2010 we have<br />
assumed the 2009 values;<br />
c) The column “records per year” is the actual number of times these vessels reported in their<br />
catch logs to be in each area;<br />
d) We also used the total effort hours reported for each fishery to estimate the expected time<br />
per day each vessel would trawl in the areas designated. Note that this does not mean that<br />
the vessel will move from the area. Typically vessels remain in an area if fishing is good.<br />
9.2 CONCLUSIONS<br />
The data shown here is a further refinement of the analysis done in Para. 6.3. We stress that these<br />
are approximations of the effort and vessels expected in the area based on the data available to us.
