    In an agreement between NORAD and FAO/UNDP the R/V “Dr. Fridtjof Nansen” has been scheduled to work in the region from Morocco to Sierra Leone within the CECAF programme from August to December 1986. A planning meeting was held on 7-9 April at Santa Cruz de Tenerife, where it was agreed that the R/V “Dr. Fridtjof Nansen” should work in Morocco for abt. 14 days in September and in November, in cooperation with the new R/V “Charif El Idrissi”. The first survey was set to the period 22 September to 5 October. Due to technical problems the “Charif El Idrissi” could not participate in the September survey, and it was decided that “Dr. Fridtjof Nansen” should do the acoustical work by itself. In November the two vessels plan to do a joint survey. In accordance with the survey plan a main acoustical coverage of the shelf from Agadir to Cape Juby was first to be made to localize the aggregations of small pelagic fish, mainly sardines. Then effort was to be concentrated on these aggregatio ns with detailed studies on biomass estimation, target strength and fish behaviour.
