Abstract The South West African Pilchard and Anchovy Biomass Survey was conducted on the Africana Voyage 074 from 22 June - 4 July 1989. The objectives of the survey were to undertake an acoustic / trawling survey of the pilchard stock off SWA and arrive at a stock estimate; to survey the horse-mackerel and anchovy stocks off South West Africa (SWA) and obtain stock estimates if possible and to collect the environmental information on the habitat of the above species primarily by means of Conductivity-Temperature-Depth (CTD) and U³ dips in the upper 200m.
