Effort was greatest in block 737 where 51% of the total buoy density was observed, after standardizing for the area surveyed. This was followed by block 757 with 36% and block 738 with 13%. Effort in block 757 was initially the most consistent registering the smallest change between the first and second survey while the remaining block-specific densities declined each month (Figure 2b). Block 757 densities registered the largest month-month decline with 48% fewer buoys observed between the December and January surveys, as compared to the October baseline. The subsection densities revealed distinct variations in effort within each block (Figure 3). Subsections 3, 9, and 1 lb were among the most intensively fished subsections. These include relatively unique areas, in comparison to the rest of the survey area, including the headlands of Dana Point (subsection 3) and an area located adjacent to the HPSMR (subsection lib). Effort in subsections 3 and 14b was the greatest during the first survey near the season opening while subsection lib surrounding the HPSMR.
