The shelf between Agadir and Cape Juby was covered to the 200 m depth contour in the period 23-27 September. The survey net with trawl stations are shown in Figure 1.
The main biomass of small pelagic fish was found within the 60 m depth contour between Cape Juby and abt. latitude N 29°20'. This area was then covered twice with acoustic transects and additional trawl stations in the period 27 September to 1 October, as shown in Figure 2. Finally a course track of abt. 110 nm was selected from the detailed coverage and this track was sailed four times with two coverages during daylight and two during night. The selected path was sailed during the days 2-4 October with new moon and complete darkness during night hours. The track with some few additional trawlstations is shown in Figure 3.
A total of 2200 nm was sailed on the shelf and 44 trawl stations were carried out.
