West Coast Hake Biomass on the Africana Voyage 015, January 1984

The purpose of this cruise was to survey by means of trawling the abundance of recruiting and adult hake between the Orange River and longitude 20° E. The objectives also included investigating the diurnal cycle of hake and other demersal species, to compare the trawling results of R.S. Africana with those of M.F.V. Chicha Touza, the Spanish trawler used for similar surveys, to investigate the environment of hake and other demersal species and to carry out acoustic target identification of mesopelagic species using RMT 8 nets.
