West Coast Hake Biomass Survey on the Africana 069, January 1989

The West Coast Hake Biomass Survey was conducted on the Africana 069 from 5 - 26 January 1989. The cruise was multi-disciplinary. The main target was to determine, by means of the swept area method, the present status of the hake resource on the South African west coast. In carrying out this study, it was possible also to collect some information on the environment and zooplankton (including squid larvae) in the vicinity of the catches and to determine some ecological interrelationships of...
