Abstract
The NRF/SA Pelagic and Rock Lobster Industries International Stock Assessment Workshop, held in July 2007 recommended that a relationship between the survey CV and abundance, and possibly also survey effort, be included in the operating models for anchovy and sardine. This recommendation was reiterated at the MARAM International Stock Assessment Workshop in December 2008. Initial results (de Moor et al. 2008) suggested that only a relationship with biomass could be found. Further investigations have now been carried out.
