Abstract	Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 08 and 22 June 1989 during Voyage 073 on the FRS Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. Neil Brown MK3 and MK4 CTD instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000. The objectives of the Anchovy Recruitment Survey were to assess anchovy recruitment strength in South African waters in order to recommend a final quota for the 1989 RSA anchovy fishing season; to collect data for the determination of the target strength of anchovy and other pelagic and mesopelagic species; to collect data on shoaling behaviour of pelagic fish, specifically anchovy, pilchard and red-eye; to investigate relationships between the distribution of pelagic fish, zooplankton and water temperature; to determine standing stocks of phytoplankton and zooplankton in different regions and to estimate copepod secondary production in these regions through egg-production and moulting rate experiments.
Methods	Neil Brown MK3 and MK4 Conductivity-Temperature-Depth (CTD) instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000.
