Raw CTD continuous observations from the Anchovy Spawning Stock Survey on the Africana Voyage 038, November 1985

This is raw Conductivity-Temperature-Depth (CTD) continuous data from the Anchovy Spawning Stock Survey on the Africana Voyage 038, collected between 11 and 29 November 1985. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa and the Agulhas Current Large Marine Ecosystem (ACLME) on the south coast of South Africa. The objectives of this cruise were to assess the size of the anchovy spawning stock in Cape waters by acoustic survey and estimation of egg production; describe the distribution and behaviour of other pelagic and mesopelagic fish of commercial importance; describe anchovy spawning patterns and estimate the precision of the parameters used in assessing spawning stock size by the egg production method (sex ratio, spawning fraction, fecundity, mean weight); and to investigate relationships between the distribution of pelagic fish, eggs and water temperature.
