Anchovy Spawning Stock Survey on the Africana Voyage 038, November 1985

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.
