Abstract	The objectives of the cruise were to survey by means of trawling the abundance of adult and recruiting hake; to investigate the the diurnal cycle of hake and other demersal species; to investigate the environment and interrelationships of hake and other demersal species; to establish the offshore limit of hake and monkfish distribution and to collect deep-water specimens of fish and cephalopods; to conduct mouth-opening experiments with transducers on each wing of the net, and to compare the mouth opening and fishing capabilities of V doors and Polyvalent doors; to study community interrelationships and assemblages and to collect data on hake and other species from the International Commission for the South-East Atlantic Fisheries (ICSEAF) Division 1.5, ie: north of the South African border.
